Connection of a prosthesis structure with an implant structure

A connection device for connecting a prosthesis structure with an implant structure comprises a holding shell and a retention insert. The retention insert comprises an end side and a substantially ring-shaped retention rim projecting therefrom. The holding shell comprises an end side and a substantially ring-shaped holding rim projecting therefrom. The holding rim and the end side of the holding shell form a retainer in which the retention insert can be arranged such that an outer surface of the retention rim is adjacent to an inner surface of the holding rim. Moreover, the outer surface of the retention rim is at least partly spaced from and adjacent to the inner surface of the holding rim when the retention insert is arranged in the retainer of the holding shell and when essentially no radial forces are acting on the holding rim and on the retention rim. In that the adjacent outer surface of the retention rim and inner surface of the holding rim are at least partly not contacting each other but are spaced from each other when essentially no radial forces are acting on the holding rim and on the retention rim, it can, i.a., be achieved that the retention insert is connected relatively loosely with the holding shell when the connection device has not yet been placed on the implant structure. This loose connection can allow the retention insert to be relatively easily removed from the holding shell and inserted in the holding shell without having to be substantially deformed or strained in any other way. Thus, it is possible to insert and remove the retention insert gently, which can improve the flexibility and lifetime of the connection device.

Resin material for multi-layer dental cutting

sand bright operating lever

The present invention relates to a dental sand blast operating lever. More specifically, to improve adhesive force by covering a prosthesis to the outside of teeth during tooth treatment, powder is sprayed to the inner surface of the prosthesis by air to fix an operating lever such that a coarse operation can be performed on the inner surface of the prosthesis for a long time. A lifting lever is provided so as to ascend up and down by a spring in a lever tool. A sliding groove in a horizontal direction is formed on an upper portion of the lifting lever. A reciprocating lever moving along a sliding groove is provided to be fitted to and separated from a hanging groove. A stop hole is formed in a lower portion of a body of a pressing hole, and an air pipe can be opened and closed by the pressing hole formed at the lower part of the lifting lever. An operator can push the reciprocating lever while pressing the lifting lever to fit and fix the reciprocating lever to the hanging groove of the lever tool, and thus the operator can continuously spray air and powder without continuously pressing the lifting lever. Therefore, air and powder can be uniformly sprayed onto the inner surface of a prosthesis. According to the present invention, it is possible to solve a conventional difficult problem in which an operator should evenly spray powder and air in a desired direction while continuously pressing a lifting lever. Also, the present invention has an advantage of improving workability by reducing fatigue of an operator even if the inner surface of one or more prostheses is continuously operated.

Prosthetic dentistry for false teeth that is made from pin retented inlay bridge

본 발명은 결손된 치아를 대체하기 위하여 핀유지 인레이 브리지로 되는 의치용 보철물이 개시된다. The present invention discloses a denture prosthesis that is a pinned inlay bridge to replace a missing tooth. 종래의 보철물은 지대치를 덮어 씌우므로써 자연치아의 과도한 삭제와 시술의 곤란성 및 비용이 증가되는 등의 문제점들이 있는데 이를 해결하기 위하여, 결손치아를 보상하기 위하여 양측 지대치에 인레이 브리지를 고정하여 이루어지는 의치용 보철물에 있어서, 상기 인레이 브리지(100)는 절삭 가공된 지대치(200)의 인레이와동(210) 내에 삽입되는 복수 개의 인레이(120)가 연장 형성되어 상기 지대치(200)에 형성된 핀홀(220) 내에 핀(P)으로 고정되는 것을 특징으로하는 핀유지 인레이 브리지로 되는 의치용 보철물이 제공된다. Conventional prostheses cover problems with excessive removal of natural teeth and the difficulty and cost of procedures. To solve this problem, dentures are made by fixing inlay bridges on both abutments to compensate for missing teeth. In the prosthesis, the inlay bridge 100 has a plurality of inlays 120 which are inserted into the inlay cavity 210 of the abutment tooth 200 which has been cut and are extended to form a pin in the pinhole 220 formed in the abutment 200. There is provided a denture prosthesis of a pin-hold inlay bridge, which is fixed at (P). 따라서, 지대치에 필요이상의 삭제를 방지하고, 이에 따른 고정성 가공의치 시술과정을 간략화 함은 물론, 시술비용의 저렴화를 이루고 오랜기간 사용후에도 지대치의 충치발생 등의 부작용이 억제된다. Therefore, it is possible to prevent excessive deletion of the preparation, thereby simplifying the process of fixed dental dentures, as well as reducing the cost of the procedure and side effects such as the occurrence of tooth decay after long-term use is suppressed.
