Abstract
Abstract A device for transferring the direction and position of a dental implant or its extension element, such as a spacer element, to a work model, includes a base part and an elongate upper part projecting from the base part. The device is made of an elastic material so that clamp fitting is obtained between the base part and the implant or its extension element. The upper part has a geometry which provides for retention in the surrounding impression compound and has break notches so that it can easily be shortened.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
A device for transferring the direction and position of a dental implant or its extension member to a work model, said device comprising: a unitary member including a cylindrical, wider base part having an internal hexagonal recess which is dimensioned for an accurate fitting onto a corresponding hexagonal upper part of the implant or its extension member; an upper part of said unitary member including an elongate member projecting upwardly from said base part, said upper part being designed to ensure retention of the device in a surrounding impression compound and being dimensioned to include a portion projecting beyond said impression compound; said upper part including a plurality of means for facilitating desired shortening of said upper part to eliminate said portion projecting beyond said impression compound; wherein said unitary member is made of an elastic material to ensure clamp fitting between said base part of said unitary member and the upper part of the implant or its extension member.
Claim 2
Independent Claim
160 words
A device for transferring the direction and position of a dental implant or its extension member to a work model, said device comprising: a unitary member including a cylindrical, wider base part having an internal hexagonal recess which is dimensioned for an accurate fitting onto a corresponding hexagonal upper part of the implant or its extension member; an upper part of said unitary member including an elongate member projecting upwardly from said base part, said upper part being designed to ensure retention of the device in a surrounding impression compound and being dimensioned to include a portion projecting beyond said impression compound; said upper part including a plurality of means for facilitating desired shortening of said upper part to eliminate said portion projecting beyond said impression compound; wherein said unitary member is made of an elastic material to ensure clamp fitting between said base part of said unitary member and the upper part of the implant or its extension member.
Claim 3
Dependent Claim
23 words
The device according to claim 1, wherein said upper part further includes a plurality of transverse rod-shaped elements spaced along said elongate member.
Claim 4
Dependent Claim
22 words
The device according to claim 2, wherein one of said transverse rod-shaped elements extends over t he top of said elongate member.
Claim 5
Dependent Claim
15 words
The device according to claim 3, wherein said means for facilitating shortening includes break notches.
Claim 6
Dependent Claim
38 words
The device according to claim 1, wherein said unitary member is adapted to cooperate with an elastic dummy such that an additional high damping force is obtained between said dummy and said base part of said unitary member.
