Study on Hydroxyapatite-coated Titanium Implants Used as Orthodontic Anchorage-An Experimental Investigation of Implant Stability and Peri-implant Neck Tissue in Dogs


Objective: Hydroxyapatite-coated titanium endosseous implants as orthodontic anchorage were studied. Methods: These implants, installed in the mandibles of two dogs, were loaded with the orthodontic force of 150 g for 3 months. The stability of the implant and peri-implant neck tissue were investigated with radiograph and index evaluation. Results: No implants were mobile, loosened or dislocated at the 3-month follow-up. The soft tissue around the cervical part of the implants had slight inflammation because of poor oral hygiene and stimulation of residual foods attached to the stainless steel spring. However, no resorption of marginal alveolar bone was found under sustained orthodontic force. Conclusions: The HA-coated titanium implant can be used as anchorage for short-term orthodontic treatment.
