[Criteria for choosing an endosseous implant. Clinical and fundamental results concerning sintered ceramic implants].

In our opinion, the primary criteria are: absence of severe residual lesions in case of failure of the implant, implant material with demonstrated biocompatibility and which does not interfere with modern medical imaging techniques (CAT-scan, NMRI); ceramics meet this criteria, an implant morphology allowing for perfect initial stabilization, sparing of tissue and good distribution of transmitted forces to bone, an easy, accurate and nontraumatic implantation technique, the possibility of connecting the implant to fixed or movable structures by precision prefabricated accessories, dismantlable if possible, convincing animal experiments and clinical results in large series with a follow-up of more than 10 years.
