ABSTRACT:
A spacer for dental implants of a bio-compatible material includes an inner sleeve-shaped spacer element of titanium which is part of a screw connection between an anchorage element implanted in the maxillary beneath the gingiva, and a dental prosthesis construction whose joint surface is located above the gingiva and which is disposed to absorb the loading of the screw connection. The spacer includes an outer spacer sleeve of porcelain or ceramics which wholly or partly encloses the inner sleeve-shaped spacer element. The ceramic or porcelain sleeve may, by grinding and coating with porcelain of different colors, be caused to visually approximate a dental cervix and gingiva and, thereby, not contrast with the natural dental cervix color and gingival color.
