HA-coated titanium implants were placed surgically into dog mandible to protract the mandibular second molars with an orthodontic force of 150 g. During the force application period of 3 months, the movement of the molars was tested periodically and relevant reasons of movement were analysed. The results showed that the mesial moving distances of the second molar were respectively 1.04 mm, 1.68 mm and 1.76 mm at the first, second and third month, and the main reason of tooth mobility was ascribed to the implant anchorage. It can be concluded tiat HA-coated titanium implant can be used as anchorage for moving and fixing posterior teeth in the orthodontic treatment.
