[Stability of HA-coated titanium implants used as orthodontic anchorage].
12 two-stage HA-coated titanium implants were inserted into the mandibular alveolar bones of two dogs were loaded with orthodontic force of 150 gram for 3 months. The stability of the implants under orthodontic force were studied with intraoral and radiographic examinations. The results showed that both intraoral and radiographic analysis were reliable for assessing implant stability, and no signs of fixture dislocation were found during the force application period (P > 0.05), while the abutment was tilted after being loaded for 2 to 3 months. This suggests that HA-coated titanium implants remain stable enough under orthodontic force and are suitable as anchorage for short-term orthodontic therapy after design of the implant neck is improved.
