Since the invention of implants, titanium has been the best material of choice due to its unique biocompatibility and the titanium dioxide (TiO2) corrosion resistance - compared to other metals which release ions into the adjacent tissue and cause inflammatory process. The important role in the biomaterial surface preparation has been a major study area for many scientists to enhance the surface properties for better dental and orthopedic implant osseointegration. The very last step of surface modification is the sterilizing method used to sterilize the implant surface before packaging. All biomaterials must be "well" sterilized before using them, however, the effect of these methods on the implant surface properties have not been thoroughly studied. Many different techniques are used to sterilize - each with its modification actions -, one of which is the oxygen plasma/ Radio Frequency Glow-Discharge (RFGD) treatment. In general, research interest in the RFGD treatment method has increased since the 1970s. Significant attention has been paid to the effect of sterilization on the surface of different biomaterials, specifically dental implant materials. Baier et al. (1984) indicated the importance of high Critical Surface Tension (CST) and surface cleanliness of the substrata for a better cell adhesion. This study was done in vivo using rabbits. They used implants with different surface energy states on three surfaces for healing periods of 10 and 20 days. Baier et al.
