Primary Implant Stability in Calcium Phosphate Cement: Clinical, Radiographic and Histological Analysis

Abstract

The Calcium Phosphate Cement (CFC) has been used as filling material for bone defects because of osteoconductivity properties, bioactivity and biocompatibility. Recent studies, mostly in animals, indicate its use as an adjunct to treatment with osseointegrated implants. Thus this work aims reporting the event in which post-extraction socket was filled with CFC-based α-tricalcium phosphate and calcium sulfate and after four months, the implant was installed through the cement which was not reabsorbed with good primary stability. Upon reopening of the implants after six months, the clinical appearance of peri-implant region was considered normal. Radiographically, there wasnt radiopaque appearance of CFCs in the alveolar region of the test anymore. Histologically, remaining CFC in direct contact with bone without intervening fibrous connective tissue was noticed. Its concluded that the CFC showed osteoconductive behavior. The material tested seems to be an acceptable option for filling the post-extraction socket with the purpose of maintaining bone volume, however, more research is needed to generalize the indication.
