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