A femoral neck prosthesis

A femoral neck prosthesis with trapezoidal cross-section

A femoral neck prosthesis 10 with a cross-section defined by a perimeter comprising: first and second arcuate portions 12,14 disposed opposite one another; first and second straight portions 16,18 disposed opposite one another and in between the arcuate portions, wherein the straight portions are non-parallel with respect to one another. The straight sides prevent rotation of the prosthesis. The arcs may be from the same circle (see fig 2b). The corners may be rounded (see fig 2d). The prosthesis may be symmetrical about an axis bisecting the arcuate portions. A method of making the prosthesis comprising removing two sections of a circle is also provided (see figs 3a-c). A modular neck portion and collar may also be provided (see figs 4 and 5). The prosthesis may be inserted into the metaphyseal cancellous bone (see fig 7).

A revision acetabular for resurfacing system

A prosthetic assembly

A prosthetic assembly (10) comprising: a body portion (12); first and second flanges (14, 16) provided on a rim (18) of the body portion; the first and second flanges being provided with first and second openings (20, 22) respectively; and a bridging member (24) connectable to the first and second flanges such that the member spans between the first and second flanges, the member being provided with a third opening (26); wherein the first, second and third openings are suitable for receiving first, second and third bone attachment means (28, 30, 32) respectively. The prosthetic assembly is suitable for affixing to the acetabulum, and in particular suitable for use in repair or revision surgery.

TWO-PART MODELLING AID

A two part modelling aid () for connection to a dental implant component (), the modelling aid comprising a hollow base part () comprising an open apical end (), an open coronal end () and a tubular side wall () extending from the apical to coronal end along a linear longitudinal axis (L), the side wall having an interior and an exterior surface, one of said surfaces comprising an anti-rotation section () having a non-circular symmetric cross-section in a plane perpendicular to the longitudinal axis, and a hollow angled part () comprising an open apical end (), an open coronal end () and a tubular side wall () extending between the apical end and coronal end and having an interior and exterior surface, the tubular side wall forming an apical portion () of the angled part extending along a first linear axis (L), and a coronal portion () of the angled part extending along a second axis, the second axis being non-coaxial to the first axis such that the tubular sidewall creates a non-linear channel (), the apical portion being sized and shaped to form a friction fit with the base part, wherein, when the base part is connected to the angled part, a closed channel () is formed extending from the apical end of the base part to the coronal end of the angled part, the first axis of the apical portion of the angled part being coaxial to the longitudinal axis of the base part and the anti-rotation section of the base part being exposed on a surface of the base part. 1.

SYSTEM AND METHOD FOR MANUFACTURING DENTAL WORKPIECE

A system is disclosed for manufacturing a dental workpiece. The system may have a subtractive machine configured to manufacture a base of a dental device from a material blank, and an additive machine configured to manufacture a top of the dental device by adding material onto a surface of the base. The system may also have a controller in communication with the subtractive machine and the additive machine. The controller may be programmed to receive digital data corresponding to a mouth of a particular patient, and to control operation of the subtractive machine to customize the base based on the digital data. 1. A system for manufacturing a dental device , comprising:a subtractive machine configured to manufacture a base of the dental device and a support structure comprising an outer frame from a material blank;an additive machine configured to manufacture a top of the dental device by adding material onto a surface of the base being mounted with the outer frame inside the additive machine; anda controller in communication with the subtractive machine and the additive machine, the controller being programmed to:receive digital data corresponding to at least one of a mouth of a particular patient and the dental device; andcontrol operation of the subtractive machine to customize the base based on the digital data; wherebythe outer frame at least partially surrounds the base and comprises one or more connectors that extend between the outer frame and the base thereby functioning as an adapter for use in placing the dental device inside the subtractive machine and the additive machine.2. The system of claim 1 , wherein the controller is further configured to control operation of the additive machine to customize the top based on the digital data.3. The system of claim 1 , wherein the controller is further configured to:determine in a virtual model of the dental device a first location of at least one feature having geometry that can be fabricated by the subtractive ...
