DOI: 10.11607/prd.3558, PubMed ID (PMID): 29447307Pages 165-170, Language: EnglishNevins, Myron / Parma-Benfenati, Stefano / Sava, Cosmin / Sava, Catalin / Quinti, Franco / Galletti, Primo / Mendoza-Azpur, Gerardo / Valdivia, Erik / Koo, Yong-Han / Kim, David M.The goal of this investigation was to evaluate the bone-to-implant contact (BIC) of dental implants placed into fresh extraction sockets without pre-existing periapical pathology. When the extraction sites exhibited a gap distance of > 2 mm, autogenous bone harvested from surrounding surgical sites was grafted to fill that gap with no barrier membranes. All implants were clinically stable and successful at 6 months postoperative. The histologic examination demonstrated an average of 66.2% BIC for all five immediately placed dental implants. The results of this study provided sufficient histologic and histomorphometric knowledge to support immediate dental implant placement in carefully selected clinical scenarios.
