Aim: 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. Conclusion: 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. World J Orthod 2008;9:95104.
