ABSTRACT:
A screw implant for securing a dental prosthesis comprising a threaded part (4) which can be screwed into the jaw, and an occlusal structural support (2) which has a conical head (8) and an inside thread (22) for an occlusal screw (24). A cap (12) is attached by means of the occlusal screw to the head. The screw head (26) is supported by a bearing surface (28) on the occlusal end face (30) of the cap, and the outer diameter of the screw head adjacent the bearing surface is substantially the same size as the outer diameter of the end face of the cap. The screw implant is simple to produce and manipulate and improves oral hygiene.
