Effect of bioactive grade surface on in vivo behavior and mechanical stability in titanium based implant surface-modified by plasma spray coating and chemical treatments.

Abstract

Geometrical and chemical designs of an implant surface affected the stabilization of implant and the healing of tissue. In this study, effects of surface designs in implants on in vivo behavior and mechanical stability were compared by histological and mechanical analyses. The implants were transversely grafted on dog thighbone and healed for 4 and 8 weeks. The pull-out strength between living bone and implant was evaluated by universal testing machine (UTM).
