Outline of Final Research Achievements

Though orthodontic onplant anchor device would not injure dental roots and tooth germs, it takes much time to fix on the alveolar bone. The purpose of this study was to develop new orthodontic onplant anchor device composed of optimum material and shape configured by biomechanism. Apatite-collagen coating titanium rod was transplanted beneath the periosteum of rat parietal bone. The results showed that the titanium rod was covered with new bone by 4 weeks, and titanium rod with a section of half circle showed strong fixing.
