Abstract

A healing cap (100) is distinguished by a bevel (116), particularly in the region to be positioned labially, the bevel being advantageous for conditioning the soft parts, as well as a firm bearing on the associated implant (1), which is achieved by means of a mating shoulder (115) and an adaptable end portion (121) of a pin (120) or a centering bead. An occlusally applicable screw (200) can be mounted in the healing cap (100) beforehand, making it easier to handle. A special protective cap is provided as an intermediate treatment and as a temporary sealing element.

Claims

1. A healing cap for an intraossally positioned dental implant, comprising:

a roof part having a top surface, an outer circumferential surface, a lower circumferential shoulder edge, and a conical mating shoulder located on an underside of said roof part, said mating shoulder being of a shape complementary to a shoulder of the implant;

a bevel depending from said top surface and positioned on said circumferential surface and extending partly therearound, said bevel ending above said shoulder edge;

a chamfer extending downward from said bevel to said shoulder edge;

a through-bore extending axially through said healing cap; and

a screw inserted into said through-bore, said screw securing said healing cap on the implant.

2. A healing cap according to claim 1, wherein said bevel extends over approximately half said circumferential surface, said bevel tapering smoothly downwards.

3. A healing cap according to claim 1, wherein said bevel extends completely around said circumferential surface.

4. A healing cap according to claim 1, further comprising an axial pin depending from said underside of said roof part, said axial pin including an end portion having a shape complementary to an inner contour of the implant, said conical mating shoulder of said roof part extending from said circumferential shoulder edge towards said axial pin in the form of a circular ring.

5. A healing cap according to claim 4, wherein said axial pin has a frustum-like shape, which creates a centering bead at a transition to said mating shoulder.

6. A healing cap according to claim 1, wherein said through-bore includes a screw head receiving part ending in a conical seat and an internally threaded section extending downward from said conical seat.

7. A healing cap according to claim 1, wherein said top surface includes a rounded transition to said circumferential surface, said rounded transition having a convex contour.

8. A healing cap according to claim 1, wherein said screw includes a screw head and a screw shank having an unthreaded part and a threaded part, said unthreaded part depending from said screw head, said threaded part depending from said unthreaded part and having a larger diameter than said unthreaded part.

9. A healing cap according to claim 8, wherein said screw head includes:

a recessed contour in an upper side thereof, said contour sized and shaped to receive a turning tool; and

a conical base on a lower side thereof, said conical base being positioned above said screw shank.
