Abstract

The ultimate goal of titanium dental implants is to obtain bioactive fixation between the implants and the native surrounding bone. The osseointegration of titanium dental implants is critically dependent on the mechanical and biocompatible properties of the implant surfaces. The medical grade titanium has good biocompatibility and excellent mechanical properties, except the lack of bioactive surface property. Despite its successful use, there is still room for improvement, with respect to faster bone healing or better healing in compromised tissues and conditions. Surface modification of dental implants has proved to accelerate the osseointegration. Rough surfaced implants increase bone-to-implant contact and speed up bone apposition. Among several methods being introduced to produce a rough surfaced implant, coating with calcium phosphate (CaP) has proved to be successful.
