title: Placement of hydroxyapatite-coated endosseous implants in fresh extraction sites: a case report.
abstract: This case illustrates the use of the principles of guided tissue regeneration to achieve osseointegration of an endosseous dental implant. One implant was placed immediately, with hydroxyapatite and a barrier membrane, in an extraction site, while another was placed in a healed site. Eighteen months postinsertion, the implant placed in the extraction socket exhibited better maintenance of crestal height than did the implant inserted in the healed site.
