Effects of methods of hydration of a biphasic ceramic graft on bone regeneration of extraction socket defects.

Background: Alveolar volumetric changes are inherent to the healing process after tooth extraction and filling of the extraction site with biomaterials can reduce these volumetric changes and provide a more favorable environment for the future prosthetic restoration with implants. Among the biomaterials available, biphasic ceramic compounds have shown promissing clinical results, however, histologic evaluation of bone tissue response to different hydration and incorporation methods are limited. The objective of this study was to comparatively evaluate in vivo the osteoconductive potential of the biphasic ceramic bone substitute (SBC) composed of beta-tricalcium phosphate and hydroxyapatite after different hydration methodologies in rat extraction sockets.
