Radiographic Evaluations On The Osseointegration Of Photo Catalytically Modified Dental Implants In A Murine Model

Osseointegration is defined as: a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant, without intervening soft tissue, is critical for implant stability and considered a prerequisite for long-term clinical success of endosseous dental implants. Many types of implant surface modification are available nowadays to enhance osseointegration. Light-activated TiO2 surface is one of the surface treatment of titanium. The purpose of the present study was to investigate the effects of the implants, which were coated with the light responsive photocatalytic material, on osseointegration. Maxillary first molars of 6 male C57BL/6NCrSlc mice were extracted bilaterally. Eight weeks after the extraction, two implants were placed in both sides of the maxilla. Photocatalyst implant was placed on the right side (test group) and conventional pure titanium implant was on the left side (control group). After 3, 4 and 6 weeks of implant placement, the animals were sacrificed. The implants and the surrounding tissues were analyzed radiographically. All implants were osseointegrated into bone. But there were no statistically significant differences.
