Tissue integration of A12O3-ceramic dental implants (Frialit)--a case report.
The tissue intraosseous integration of A12O3-ceramic dental implants (Frialit) is studied in a patient case, where an implant-fracture made it necessary to remove the implant from a patient's jaw. The surgical removing of the apical part of the implant with the use of a Trepan bur made it possible to examine and visualize histologically and microradiographically the tissue adjacent to the implant. The results of both the histological and microradiographical studies showed that a good healing and osseointegration of the ceramic dental implant (Frialit) was obtained. A direct contact was established between the implant and the surrounding alveolar bone and the induced bone tissue fitted exactly to the contour of the implant. No evidence was found of formation of a connective tissue capsule between the implant and the adjacent alveolar bone nor of any inflammatory reaction in the interface zone. In summary it was evident from the result of the present study that the biocompatibility properties of pure aluminoxide ceramics (A12O3) are excellent and can be recommended as an acceptable alternative among the many different implants, that now are available on the market.
