| Research Abstract |
The purpose of this study was to develop a new minimally invasive implant system specialized for implant-supported overdentures focusing on the oral rehabilitation of elderly people with highly-absorbed edentulous jaw. Biomechanical tests revealed that photofunctionalization significantly increased the bone-implant integration strength. The effect of photofunctionalization appeared to be greater in push-in test compared to removal torque test. Our study indicates that photofunctionalization can pursue a novel strategy for minimally invasive short implant system characterized by both maximum load bearing and less removal torque.
