Abstract
INTRODUCTION: The purpose of this clinical study was to evaluate the stability of titanium miniplates used as anchorage for orthodontic treatment. METHODS: Seventeen patients with a total of 68 miniplates were enrolled. The miniplate placement sites were evenly divided between the maxilla and mandible. The patients underwent distal movements of the molars with miniplate anchorage to correct anterior crossbite or crowding without extracting the premolars. RESULTS: The posttreatment clinical examination showed that 5 miniplates, all in the mandible, failed before the end of treatment-a 7% failure rate. CONCLUSIONS: Further studies, perhaps with titanium miniplates of a different design, might be necessary to identify important factors for decreasing the incidence of complications when miniplates are used for orthodontic anchorage.
