Spacer for dental implants
Abstract
Abstract The disclosure relates to a spacer for dental implants of a bio-compatible material. The spacer includes an inner sleeve-shaped spacer element (4) of titanium which is part of a screw connection between an anchorage element (fixture) (1) implanted in the maxillary beneath the gingiva, and a dental prosthesis construction whose joint surface (11) is located above the gingiva and which is disposed to absorb the loading of the screw connection. The spacer further includes an outer spacer sleeve (12) of porcelain or ceramics which wholly or partly encloses the inner sleeve-like spacer element (4). The ceramic or porcelain sleeve may, by grinding and coating with porcelain of different colours, be caused to visually approximate a dental cervix and gingiva and, thereby, not contrast with the natural dental cervix colour and gingival colour to the same extent as does the titanium material.
