Surface Modifi cation of Titanium Implant Infl uenced to Osseointegration

Abstract

Titanium and its alloy are the most widely used material for dental implants as these materials are highly biocompatible and possess excellent mechanical properties and corrosion resistance. However, their application as implant materials is lack of bioactive behavior, on the other words, they cannot form a direct mechanically stable bond between their surface and the surrounding bone tissue. To overcome this limitation, research efforts have focused on modifying implant surface to improve the biological response. Several techniques of surface treatments have been developed and applied to promote the mechanism of osseointegration with faster and stronger bone formation. This article is object to review on the various surface modifi cation techniques and their potential effects on the performance of dental implant which are currently used and available for commercial in Thailand. In addition, the future trends in dental implant surfaces are discussed.

Key words: Surface modifi cation, Dental implants, Osseointegration
