Clinical application of accelerated osteogenic orthodontics and partially osseointegrated mini-implants for minor tooth movement.

INTRODUCTION: This article illustrates a new treatment system combining accelerated osteogenic orthodontics and osseointegrated mini-implants for minor tooth movement in severely compromised conditions. The procedures, advantages, efficacy, and indications of this method are discussed.

METHODS: Three patients who needed minor tooth movement and orthodontic mini-implant treatment were recruited to use this combined technique; 1 required molar intrusion, and 2 required molar uprighting. C-Implant (diameter, 1.8 mm; length, 8.5 mm) were placed, and, after 5 weeks of healing, decortication of bone was performed near the malpositioned teeth by using a low-speed round bur. Bleeding was controlled, and the bone graft material was placed into the decorticated area. After the flap was secured, an immediate strong orthodontic force from the C-implant was applied to the teeth to start rapid tooth movement.

RESULTS: Only a few orthodontic attachments were necessary, and the teeth moved rapidly to a good occlusal relationship without root resorption.

CONCLUSIONS: The combination of accelerated osteogenic orthodontics and a partially osteointegrated mini-implant (C-Implant) was a safe and effective treatment choice. The C-implant's surface allows partial osseointegration, so it can resist a force moment without loosening and withstand the heavy forces associated with the accelerated osteogenic orthodontics protocol.
