title: Histologic evaluation of a human periapical defect after implantation with tricalcium phosphate.
abstract: This case report describes the effect of tricalcium phosphate implantation in the treatment of a chronic periapical abscess. Ceramic implant materials are biocompatible and are currently being used to restore alveolar bone loss resulting from periodontal disease, endodontic infections, and residual alveolar ridge resorption. However, use of such a material in this case led to persistent infection and additional bone destruction. Thus, the use of a ceramic implant material to accelerate periapical bone repair is not recommended in areas where a chronic bacterial infection is present.
