Abstract
A dental implant having a core member formed of a gingiva-compatible metal for mounting a dental superstructure in the shape of a tooth crown; a fastening element for dental bridges or the like, wherein the core member is connected with a tissue-compatible biostable polymer matrix which contains reabsorbable, bioreactive sintered calcium phosphate. The core member is constructed from a metal plate flat in cross-section and conformed with the implant shape and which is provided with apertures, wherein the polymer matrix is a covering encompassing the metal plate on all sides thereof and is constituted of a biostable polymer material and reabsorbable finely-divided, sintered calcium phosphate, and in which the apertures are filled with reabsorbable sintered calcium phosphate.
Claims6
In a dental implant including a gingiva-compatible metal core member for mounting a dental superstructure in the form of a tooth crown, a fastening element for dental bridges or the like in which the member is connected with a tissue-compatible, biostable polymer matrix having reabsorbable, bioreactive, sintered calcium phosphate, the improvement comprising:
- said core member being a flat metal plate (1, 11) conformed in shape to said implant and being provided with through-apertures (2, 12) and the polymer matrix is a coating (4, 14) encompassing the metal plate (1, 11) on all sides thereof, and said through-apertures (2, 12) are filled with reabsorbable, sintered calcium phosphate (6, 16).
