Implant for holding and/or forming a dental prosthesis, implant set and kit with an implant set.

[0001] The invention relates to an implant for holding and/or forming a dental prosthesis according to the preamble of claim 1.

[0002] The implant can in the lower jaw - or upper jaw bone of a patient are used and there for holding a component, particularly for holding said assembly element for the formation of a dental prosthesis abutment has often also serve. This may have for example a single artificial tooth crown and forming an artificial single tooth. The implant may also together with at least one additional implant or a residue of a natural tooth for holding and/or forming a bridge or a partial - or full denture serve.

[0003] Many known implants have a hole with an internal thread on. Components used for establishing a dental prosthesis, in particular structure elements, can then be bolted to the implants.

[0004] Many known implants are wholly made a one-piece implant body of a metallic material, about titanium or a titanium alloy. Wherein the external thread is screwed into the inner thread of such implants and screws or other components are normally formed as a control - implants or standard thread, as usual in metallic screws and nuts etc. for general fixing purposes. The internal thread in metallic implant bodies therefore have ridges and grooves, the wedge - or triangular in profile in axial section are normally about respectively.

[0005] It is also known implants, the implant body also consist entirely of a ceramic and have a hole with an internal thread.

[0006] Ceramic material is a metallic material as the material of the natural jawbone similar. The bone can therefore may increase on a ceramic implant body better than a metallic implant body. If an implant said gingiva, i.e. the soft tissue, or at least contacts penetrates, the soft tissue may also connecting to a tight and close to a metallic implant body as ceramic implant body. Ceramic implant material in the region of the soft tissue also reduces the risk of infections and therefore the deposit of plaque and gingival fading. In certain patient allergies may trigger further titanium, which is avoided by ceramic material. Ceramic implant material can advantageously impact on the stability and durability of all these reasons anchoring of the implant. Titanium implant body further have an approximately gray color, therefore when in the front mouth portion by the gleam possibly through soft tissue can be directly visible fading or gums. Ceramic implant body have a similar color as natural teeth against it, so that when they are in the front mouth portion hardly disturbing also aesthetically.

[0007] Ceramic implant body therefore have various advantages relative to metallic implant bodies. But they have the disadvantage, that it is quite difficult and costly, they produce internal thread. It is important to note, that these female threads have only small, for example about 1.8 mm or 2 mm nominal diameter end amount. It is possible in particular not practically, to form the internal thread in ceramic implant bodies as a control - or standard thread. The internal thread of known ceramic implant bodies have for example in axial section profile or rounded grooves and ribs therebetween quite flat peaks. These female threads are certain mass from a combination of round and flat threads so threads. The external thread of the screw for screwing into the ceramic implant body provided with internal threads complementary to the external thread and other components must of course in profile or axial cut arcuate ribs and grooves have flat bottom.

[0008] In constructing a dental prosthesis is often at least a first component, e.g. a healing or closure element - and possibly an impression member, temporarily screwed to an implant. Then at least one component, in particular a construction element is permanently screwed to the implant. The components can be fixed temporarily and permanently screwed originally separate according to their species and formations with screws or with fixed, non-continuous threaded bolt and with them permanently on the implant. Depending on the nature of the dental prosthesis to be formed here are used, the position of the implant in the mouth and the nature of the different implants jaw bone in the jawbone and particularly different components or permanently screwed to the temporary implants.

[0009] Now known implants with metallic implant bodies and when both known implants with ceramic implant bodies are provided for selective use, for screwing into the ceramic implant body must screws and threaded bolt thread than the screws and have certain different threaded for screwing into the metallic implant body. As a result, manufacturers of implants that a steep numerous different screws, threaded bolt screwed implants and other components and bearing must take. Accordingly dental clinics and dentists, the selectively inserting implants with metallic and ceramic implant bodies, many different screws and others must also obtain components and possibly take on bearing. This is causing considerable additional costs.

[0010] There have been proposed implants, have a metallic base body, and whose outer surface is coated with a ceramic material. The production of such appropriate and durable coatings but is difficult and costly. Such implants are therefore rarely used practically.

[0011] Further from the publications wo 00/06 042, wo 2005/058 178 and CH 702,586 known implants, the implant body and a non-releasably secured thereto a metallic, a short portion of the metallic implant body surrounding ceramic sleeve. The ceramic sleeve is in the vicinity of the mouth of the hole in the bone and trans-gingival implants also penetrates the gums. The gums such implants, i.e. the contacting portion of the outer surface of the implant is therefore equal to soft tissue formed entirely of a ceramic implant body as with implants consisting of ceramic material. The implants with a ceramic sleeve so similar benefits as a result in the range of this all-ceramic implant. On the other hand have a metallic implant body and a ceramic sleeve with implants in the implant body formed from the metallic outer surface (only) the same properties as a fully metallic implant.

[0012] The invention is based on the, disadvantages of the known implants and other components for building and to avoid forming a dental prosthesis. In particular the whole and possibly coming in contact with the bone with the soft tissue to the outer surface of the implant in the known equal area -, ceramic - existing implant bodies consist of ceramic material completely. The implant should be as small as possible can be produced simply and with further costs. To enable also, with screws or bolts to screw on permanently or temporarily on the implant components, have the same external thread as the screws and threaded bolt for screwing components at metallic implant bodies.

[0013] This task is based on the known, entirely of ceramic implants according to the invention by an implant existing with the features of claim 1 dissolved.

[0014] Claim 1 advantageous refinements of the implant from the dependent claims from go out.

[0015] The invention also relates to an implant assembly with the features of claim 8.

[0016] The invention relates to a kit having the features of claim 9 also.

[0017] At a invention with a ceramic implant body in its hole and a fixed implant, internally threaded, preferably metallic or plastic sleeve is possibly the Aussennfläche of the implant by the ceramic implant body at least substantially formed. This is thus in particular the portion of the implant surface, in contact with the bone and the soft tissue of a patient can pass. The sleeve is preferably completely within the hole of the ceramic implant body and for example in distance from the mouth of its hole arranged. The outer surface of the implant is then completely and exclusively by the ceramic implant body formed. The implant relative to the contact with the bone and soft tissue has therefore the same properties and advantages as a fully and exclusively of ceramic material existing implant.

[0018]Amanufacturer of implants and associated therewith a kit components can now with an implant set steep, the at least one implant according to the invention with a ceramic implant body and a in this SE fixed, internally threaded, preferably metallic sleeve and at least one implant comprises, the exclusively from a metallic, internally threaded implant body. The implant set comprises preferably several implants in both types.

[0019] The kit may also matching components to these implants, in particular screws, threaded bolts and screwed with such construction elements comprise. The kit can also comprise locking elements or healing elements screwed to the implants, the implants during the healing stage cover and their holes pass to closing. The kit can further to the implants and structure elements matching and possibly directly to the implants for creating prints comprise Abformelente screwed.

[0020] In the internal thread of the ceramic implant body of the invention attached implant, preferably metallic sleeve can have the same thread characteristics as the internal thread of an implant, the implant body is entirely of a metal. With the feature "the same thread characteristics" is meant here, the internal thread of the sleeve and of the completely metallic implant body within the normal manufacturing tolerances on the same nominal diameter - -, the same core diameter, the same thread profile, have the same pitch and the same direction of rotation. Further wherein said female threads are two types of implants have the same number of single thread or otherwise processes.

[0021] For clarification was noted however, that the mutually corresponding mouths or ends of the internal thread or, more precisely, the mouths or ends of the internally threaded hole end portions of the sleeve and this completely metallic implant body, may be the same or possibly a little instead formed differently. The hole portions with the internal threads can for example up to the mutually corresponding internal thread ends and including cylindrical or slightly conical ends of these be for example, about conical recesses, have. In this respect it should be noted, that the holes in the implant bodies so are blind holes, so that the internal thread of a fully and exclusively from a metallic implant body existing in a portion of the blind hole of the implant necessarily implant. Although the sleeve could also have a blind hole, but is preferably open at both ends and having a through hole provided their internally threaded. The base of a blind hole located closer to the end of an internal thread and is often slightly different but almost inevitably formed as a through hole at the end of a finding end of an internal thread. It should also be noted, that the internal thread of the metal sleeve and a fully metallic implant body preferably metallic or have different lengths can approximately equal.

[0022] The internal thread are constructed and dimensioned however, that screws and threaded bolt with external threads for implants with a ceramic implant body both same and a sleeve fixed in this for a metallic implant body existing implants can be used completely. We can therefore identically constructed for example screws, identically constructed threaded bolt, identically constructed verschlußbzw. Healing elements, identically constructed and any constituent elements screwed, identically constructed Abformelente selectively as desired with a ceramic implant body and a sleeve fixed in this implants or implants screwing, the consist entirely of a metallic implant body.

[0023] The internal thread in the sleeve and in the metallic implant bodies and the external thread of the screw which can be screwed into this internal thread and other components preferably consist of control - or standard threads, for example from metric to ISO control threads. They can but instead by customs standard - or control thread, such as the widespread default in the US - or control thread are formed according to the default (UTS at) use Unified threaded. The nominal diameter of the thread is preferably at most 2.5 mm, preferably at least 1.5 mm and 1.8 mm or approximately 2 mm for example about.

[0024] The invention gives the advantage, that the number of different screws, threaded bolts and other components, the for selectively screwing into implants with a ceramic implant body inserted therein and a bushing or implants with a fully metallic implant body are required, can be significantly reduced.

[0025] Of the invention and further features and advantages of this article are now explained with reference to the drawings embodiments represented. In the drawings shows:

[0026] 1 1 Into the bone of the lower jaw and these are figfig. covering 3 showing a patient's soft tissue. The bone with a bone penetrating hole in it is 1 when comb ST, namely a blind hole provided.

[0027] 1 Is a designated fixed dental prosthesis with the bone 5 as a whole. The user has a holding part 11 on it and forming implant, the rotationally symmetrical to an axis 13 is generally. The implant in the bone is fixed a gingival 11 is trans 1. It projects out from the bone and soft tissue also penetrates the 1 accordingly, i.e. the gums. The implant has a non-visible, closer to the base of the hole ST finding, first end and a second end, near the bone outside of the bone is the comb.

[0028] The main component of the implant 11 consists of a ceramic implant body 15. This forms the anchoring portion of the implant. The anchoring portion is generally cylindrical, for example with a - or multiple external thread into the hole of the bone in this screwed and 1 provided and anchored. The ceramic implant body 15 further forms the projecting shoulder part of the implant from the bone a little, for example towards the second end of the implant tapers conically about. The outer surface of the implant body 15 when the mouth of the hole can also closer end portion of the anchoring portion and the shoulder portion of the ST located implant at least one respective annular rib.

[0029] The ceramic implant body 15 has an axial hole 15a, the the first end of the implant by a arcuate or conical base 15b is completed for example in axial section of a blind hole and is therefore. A cylindrical hole portion closes the base 15b 15c on. This is in the vicinity of its distal end provided with an annular groove 15d 15b further from the base. To the cylindrical hole portion closes a conical mouth portion 15e at 15c, 15b extending from the base and away from the cylindrical hole portion located at the second end of the implant for 15c situated 15f of the hole widens in mouth 15a. The mouth 15f is an annular, for example conical shoulder surface 15g enclosed and limited. The conical mouth portion is provided with a recess at a circumferential location 15e 15h, towards the mouth along the axis 13 into the conical mouth portion 15e 15f expires.

[0030] 11 Also has another metallic sleeve 17 on the implant, the implant body 15 is entirely within the hole 15a of the ceramic, spaced from the mouth of the hole is generally cylindrical and coaxial with the axis and 15f is 13. The sleeve 17 is still figfig. 2 separately in open at both ends and therefore has subscribed a through, axial hole 17a. This is at least substantially over the entire length of the sleeve with an internal thread extending 17b provided. The outer circumferential surface of the sleeve is mostly by a cylindrical lateral surface section 17c formed. The mouth of the hole of the ceramic body closer to the end portion of the sleeve 17 is located 15 15a by axially parallel slots in at least three and eight somewhat resilient tongues divided for example 17d. Each tongue has at its free 17d, closer to the mouth of the hole 15a 15f from the cylindrical lateral surface section 17c and end located from the axis 13 path outwardly projecting cam 17e. Each cam at the end of the sleeve has a flat, rectangular stop surfaces on axis 13 17f. This closes a exterior surface portion on the outside of the cam 17g to, forms a part of a cylindrical surface. On the external surface portion follows a 17g 17h exterior surface portion, the cylindrical lateral surface section and inclined towards the axis 13 for 17c and is part of a cone surface forms.

[0031] Since the ceramic implant body 15 in contrast to known, instead of a completely ceramic implants extending relatively close to the mouth of the internal thread only 15f has annular groove disposed hole 15d, can much easier and at a lower cost than the known he produced, completely ceramic implants. On assembly of the implant 11 is the metallic sleeve 17 into the hole 15a of the ceramic implant body 15 pushed. The inclined outer surface portions allow the cam 17e 17h, in that the cam slightly into the hole 15a slide into. When the sleeve is pushed into position achieved in 1 figfig. subscribed, catches the cam 17e into the annular groove of the ceramic implant body 15 and then engage behind a 15d their stop surfaces also serving as abutment surface 17f, closer to the mouth of the hole located in the annular groove side surface 15a 15f 15d. The ceramic implant body 15 and the sleeve 17 are cylindrical hole portion in the cylindrical lateral surface section 15c or 17c by a light interference fit also assembled. The metallic sleeve is engaged by the cam 17e and the press-fit joining in the ceramic implant body fixed in position 1 in the figfig. subscribed. The sleeve if necessary but could additionally or instead of the mounting by a press fit with an adhesive or cement in the ceramic implant body be fixed.

[0032] 5 The dental restoration has a structural member 21 with a blind hole of the ceramic implant body 15 21a seated on inner portion 15a. This has a conical main portion, the mouth portion of the hole on the inner surface of the conical 15e 15a rests. The inner section further has a short cylindrical end portion, the cam 17e into the cylindrical hole portion to the vicinity of 15c engages. The conical support portion at a circumferential location has a away from cam projecting outwardly and into the recess 15g 21b on. This defines a rotational position about the axis of the construction element and secures it against rotations 13. The structural member 21 has a holding portion projecting from the hole 15a 21c, for example a tapered pillar away from the implant forms. The structural member 21 is with a continuous, coaxial hole 21 d is provided axis 13. This is stepped and has a narrower and a further cylindrical hole portion and a hole arranged between these portions, annular, planar bearing surface on. The closer hole portion opens into the hole 15a of the ceramic body 15.

[0033] The structural member 21 is often referred to as occlusal screw with a screw 23 11 fixed to the implant. The screw 23 has a further portion of the hole 21 d is arranged, on said, annular bearing surface head, a cylindrical hole portion extending closer to the mouth of the extends approximately, cylindrical shank and a threaded portion screwed into the internal thread of the sleeve 17 17b. This extends for example approximately until closer to the base end of the sleeve 15b located. The screw pulls the sleeve 23 in the direction of the structural member in the direction of the sleeve mouth and 15f, so that the stop surfaces of the one side surface of the annular groove to the 17f the cam stop surface and the conical bearing surface of the inner portion of the 21a 15d formed on the conical hole portion of the ceramic implant body 15e superstructure element 15 are pressed. These together with the cam engaging into the recess 15g of the ceramic implant body 21b a solid, rotary safe, stable and tight connection of the structural element at least approximately with the ceramic implant body 15 21.

[0034] 5 25 Has a superstructure on the dental restoration. This is on the annular shoulder surface of the implant body 15 as well as on the holding portion 21c on ceramic 15g of the construction element is in one of the known species on the structural member 21 and on and possibly fixed directly on the implant. The superstructure for an artificial tooth crown forms for example a single tooth.

[0035] The whole outer surface of the implant 11 is by the circumferential surface, the base surface and the shoulder surface of the ceramic implant body 15 formed. The implant 1 contacts the bone and the soft tissue so the outer surface of the ceramic implant body with 3 exclusively. This consists of a biocompatible ceramic material, for example a material based on zirconium dioxide. The sleeve and the screw 23 are made of a biocompatible metallic material 17, for example titanium or a titanium alloy or stainless steel. The structural member 21 is also for example of a biocompatible, ceramic material. The course should also be biocompatible superstructure 25. The metallic sleeve 17 furthermore by the structural member 21 containing hole 15a, the screw 23 and the superstructure 25 against the environment practically completed.

[0036] Figfig. 3 into a lower jaw bone are 1, 3 and a soft tissue with a 105 seen here designated dental prostheses. This differs from the dentures in 5, be that of a metallic implant body 115 is completely and exclusively implant III to. This is for instance of titanium or a titanium alloy, has the same contour form the same outline and dimensions as the ceramic implant body 15 and also an axial hole 115a, which is a blind hole. The hole as the hole 15a has a base 115a 115b, a generally cylindrical hole portion 115c, a conical mouth portion 115e and 115f a mouth. The cylindrical hole portion is narrower than the cylindrical hole portion 15c of the body 15 115c has none of the annular groove and corresponding annular groove 15d, but is provided with an internal thread 115d. This begins the transition from conical hole portion into the cylindrical hole portion and extending in the latter 115e 115c to about near the base 115b, where it terminates.

[0037] The internal thread in the whole implant forming metallic implant body 115 115d 111 has the same thread characteristics as the internal thread 15d in the sleeve end near the bottom of the hole be 15th since 115a 115b expires, it is possibly a little longer than the continuous internal thread in the sleeve 15 15d, 15d and 115d for example both internal thread so that approximately the same usable length.

[0038] The mouths of the holes have large diameter equal or 15a 15f and 115f 115a. Further form the conical mouth portions 115e 15e and the same angle with the axes of the implants, are of equal length and have the same large diameter at their thinner ends. Since the internal thread containing, generally cylindrical hole portion 115c of the metallic implant body 115 has a smaller diameter than the cylindrical hole portion 15c of the ceramic implant body 115c, is between the hole portion and the conical mouth portion still present a transition section 115c 115e 115i, with a narrow conical enlargement and a short from a cylindrical surface is. Where otherwise previously written, has the metallic implant body 115 same shapes and dimensions as the ceramic implant body 15.

[0039] 105 The dental restoration has a structural member 21, and a superstructure on a screw 23 25. The structural element 21 of the dental prosthesis is formed equal to that of the dental prosthesis is 105 is analogous with the conical main portion 5 and its inner portion 21a on the how this conical mouth portion 115e of the hole 115a on. The cylindrical end portion of the inner portion projects into the transition section into the hole 21a 115i 115a. The structural member 21 is seated in the hole 115a in the internal thread of the metal implant body 115 with a screw which is screwed to the implant body 115d 23 115 fixed. This screw as the screw is formed equal, the 17 of the implant is screwed into the sleeve 11. The formations of the implants allow 11 and 111 therefore, identically constructed with identically formed on the implant screws 23 21 constituent elements 11 and 111 on the implant tight. The superstructure of the dental prosthesis 25 105 can for example be formed as that of the same or similar and fixed dental prosthesis 5.

[0040]Amanufacturer of implants in accordance with the manner described in the introduction can now already a kit with an implant set steep, the at least one implant formed according to figfig. 1 11, at least one and preferably several implants formed according to figfig. 3 111 implant has both types. The kit may also matching components to these implants, in particular screws, threaded bolts, constituent elements, healing elements and impression elements comprise. One can then identically constructed structure elements, healing elements with screws or bolts and possibly impression elements optionally identically formed two types of implants screwing.

[0041] Figfig. 205 211 has a dental prosthesis shown in 4 on implant, as the implant from a ceramic implant body 11 the analog 215 and a in this fixed, metallic sleeve is 217. The implant in the bone of the lower jaw of a patient 1 211 subgingingival is used. The second end of the implant is substantially flush with the bone under the soft tissue 3 accordingly comb. The axial hole 215a 215 in the implant body is somewhat shorter than the trans-gingival implant 11 into figfig. 1st possibly further the conical mouth portion of the hole 215a 215e may for example form a larger angle with the axis 13 of the implant as the conical mouth portion 15e and be shorter than this. The metallic sleeve 217 can be arranged closer to the mouth of the hole 215a 215f for example than the implant when the implant body is further 11th none of the shoulder surface 215 corresponding shoulder surface 15g present. Apart from the differences indicated previously the implant be constructed the same or similar as the implant can 211 11 into the dental restoration has a structural member 221 205 figfig. 1st still on. This has a shape adapted to the trans gingival arrangement, but otherwise is similar as the structural member 21 is formed. The structural member 221 is as the structural member 21 with a screw 23 on the implant analog to 211 screwed. 221 Is a superstructure mounted on the structural member 225. This is in contrast to a shoulder surface of the implant superstructure 25 not, but exclusively on the structural member 221 on.

[0042] Into the bone of the upper jaw of a patient are figfig. 5 301, 303 and 305 soft tissue covering the bone with a bone anchored implant 311 a denture, a screwed a screw 23 on the implant structural member 321 and a superstructure represented. The implant will again a ceramic implant body 311 and a in this fixed 315, 317 on metallic sleeve. The implant as the implant is inserted into a gingival figfig. 311 11 1 trans-very similar and shaped like this. The conical mouth portion of the hole of the ceramic body and the inner portion 315 315e 315a 321a of screwed on the implant superstructure element 321 but a smaller angle with the axis of the implant forming for example than the implant structural member for adaptation to the position of the further is the 11th implant in the bone of the upper jaw slightly asymmetrical configuration.

[0043] 6 Into the bone of the lower jaw are figfig. 1, 3 and the soft tissue with an implant showing a denture 405 411. This in turn has a ceramic and a metallic sleeve with an internal thread on the implant body 415 417. The implant is inserted in the bone as the 411 in the subgingivalImplantat211 figfig. 4, wherein for example a slightly different shape but be implant body. 6 Differs from those shown in figfig. dentures 405 in the figfig. 1, 3, 4, 5 above all however, that its structural member 421 a solid, non-permanently and the remaining portion of the superstructure element comprises continuous 42lf threaded bolt. The structural member 421 is not with a screw, screwed into the internal thread of the sleeve but by means of the threaded bolt screwed 417 421 F on the implant. Since the structural member upon screwing the implant must be rotated, it has no cam, the cam 21b of the subscribed figfig. structure element corresponds to 1.

[0044] In the left and right half of the figfig. 7 per half a trans 1 represented a lower jaw bone a gingival eigesetzten implant. Each half of the two implants are subscribed with 511 611 and each have a ceramic implant body 515 or designated 615 and 617 or a metal sleeve with an internal thread or 517.

[0045] In the left half of the implant body has a hole with a subscribed 515 Figures 515a 515b base, a cylindrical hole portion 515c, 515d an annular groove having a mouth and a conical mouth portion 515e 515f. The sleeve 517 differs from the previously described in sleeves, that the cam 517e the resilient tongues are arranged at that end of the sleeve 517 517d, the closer to the base of the hole of the ceramic implant body 515b. The annular groove 515d, into which the cam are engaged, is adapted to the arrangement of the mouth portion of the hole in the conical cam 517e and further away than the implant body in the implant body figfig. 1st 521 construction element is designated here as in 1 with a screw 23 screwed figfig. analogue.

[0046] The implant body in the right half of the 615 611 has a hole 7 figfig. subscribed implant 615a, a base and a cylindrical hole portion 615b inter 615c has. However this has none of the annular grooves 15d, 515d corresponding annular groove and over its entire length by a full cylindrical inner surface is limited. On the right side of the metallic sleeve 611 617 of the implant/subscribed figfig. 7 has a hole with an internal thread and resilient tongues 617a 617b 617d. As with the sleeve 517 when they are closer to the base end portion of the sleeve located in the hole 615b 615a. The tongues of the sleeve have not 617d 617 cam, the cam the other corresponding to the subscribed sleeves. The hole of the sleeve near the free ends of the 617 617a has a hole end portion 617e 617d tongues, the free ends of the tongues and to the base of the hole of the implant body tapers towards 615b 615a 615. For implant include a short spreading screw 611 619. This is in the region containing the tongues and/or in the region of the sleeve screwed and adjoining the latter 617 having an inner engaging on the tongues, this spreading apart extension. Fixed to the inner surface of the cylindrical hole portion in the tongues will 615c and fixing the sleeve in the hole of the implant body pressed 615a 617 615. This here with 621 with a screw which is screwed into the sleeve construction element is designated 617 Implantat611 fixed on. The formations and dimensions of the sleeve 617, 619 of the expander screw and the screw 23 are matching each other so, that the threaded part of the screw can be screwed into the sleeve 23 sufficiently deep.

[0047] Analogue as in combination with the implant in the implant in for 1 figfig. figfig. 3 was described, can also each in the figfig. 4 to 7 shown, a ceramic body and a metallic sleeve having a threaded implant to a kit with an implant set include, at least one implant with a metallic implant body has yet, wherein preferably each more identical implants both types are present. The same implant set have internal thread with the same thread characteristics associated with implants. A kit comprising such a implant set screws and/or other components can have, screws and/or optionally with threaded bolt with an implant with a ceramic body and a metallic sleeve or on a metallic implant implant of the respective implant set can be screwed exclusively. The implants and components are designed such, that the screwed components, e.g. constituent elements, both types on the same or similar implants rest.

[0048] As mentioned, may also temporarily screwed implants, healing or closure elements - be present, and for closing their holes serve the for covering the implants. The healing elements have a relatively thin for trans-gingival implants, quite flat, the implant cap covering. The healing elements for the subgingival implants have a greater dimensions in the axial direction, for example expanding away from the implant, the soft tissue by plea cap. The healing elements in both cases can be integrally or in two parts. The two-part healing elements have a cap, the screw is screwed with a initially separate implant. The one-piece integral with a threaded bolt elements have a healing cap screw may also be considered as continuous and specially shaped, their head cap for covering an implant and for closing of its hole is formed.

[0049] The implants and other components for holding and/or forming a dental prosthesis can still be modified in other ways. Particular features of the various embodiments of implants may be combined together and structure elements. For example the sleeve can also shown in addition to the 7 figfig. figfig. 7 variants described in the implant body be pressed or cemented still attachments, as described figfig. for 1. In the figfig. can further to the 1, 3, 4, 5 and 7 are screwed implants shown also constituent elements, such as the analog in a structural member associated with them have subscribed figfig. 6 undetachably threaded bolt.

[0050] Further the annular groove in a continuously in the curved figfig. 7 could by reason 515a 515b of the hole enlargement merging be replaced. Further implant body with a hole could be produced, whose mouth portion is conical rather than cylindrical. The constituent elements in the cylindrical mouth portion could then a into mating, cylindrical inner portion and have on a shoulder surface of the implant body rest. The anchoring portion of the implant body could further bone anchored a substantially cylindrical outer surface at least partially in the base of the hole without external thread or a tapering towards the bone, for example approximately conical outer surface with or without external threads having. The metallic sleeves can also possibly through sleeve from a suitable, biocompatible plastic are replaced.
