Abstract

The mechanical strength of the bone-implant interface depends on the morphology and the composition of the implant surface. The great variety of coating materials as well as the condition of the surfaces to be covered, makes a comparative and preclinical evaluation of the different materials for prostheses necessary. The results, the validity and the limits of the extraction tests are discussed in this article.
