Orthodontic anchorage should be performed for the movement of malpositioned teeth. It is, however, difficult to obtain a satisfactory effect when key teeth potentially suitable for anchorage are missing. As an alternative, osseointegrated implant fixtures may be used for orthodontic anchorage. A 22-year-old female with a maxillary zygomatic complex fracture and loss of the mandibular incisors, right canine and right first premolar is presented. After primary reduction and fixations on the fracture, osseointegrated implant (Brånemark system) fixutres were inserted for orthodontic anchorage to facilitate repositioning of the mandibular left canine and stabilization of the posterior teeth. Orthodontic treatment was satisfactorily achieved, and no movement of the implants was observed at the end of treatment. The implants were finally applied to bridge abutments to complete prosthodontic treatment.
