Anterior torque control using partial-osseointegrated mini-implants: biocreative therapy type I technique.
OBJECTIVE
To show the effectiveness of the osseointegration-based mini-implant (C-Implant) in managing anterior torque control during en masse retraction of anterior dentition. Severe gable bends can be applied on utility archwire that is directly engaged in the hole of C-Implants to generate anterior torque on the anterior segment of teeth to resist lingual tipping during en masse retraction. This treatment mechanics is called the biocreative therapy type I technique. Partial osseointegration of C-Implants on the anteroposterior alveolar ridge is stable enough to resist intrusive force, vertically, and retraction force, anteroposteriorly, at the same time.


METHODS
The different treatment concept and procedure for treating maximum anchorage using the C-Implant is shown with case reports of treated patients. The biomechanics and clinical applications of this treatment are also described.


RESULTS
The authors show how C-Implants can provide effective torque control during anterior retraction, the potential indications thereof, and the simplicity of the mechanics.


CONCLUSIONS
The resistance to rotation force of the C-Implant can be used for anterior intrusion during retraction without concern of extrusion on posterior anchorage teeth. The biocreative therapy type I is a simple and quick technique for anterior torque control.
