Abstract

Background:  This article presents a new concept of “Retraction of Canine”. A tooth-borne, custom made, intraoral distraction device is used to distract the canine distally into the first premolar extraction space following the cortication around canine, grooving vertically inside the extraction socket. It is activated 3days after the extraction. The anchor units are the first molar. This article involves left upper canines which are distracted bodily 6.5 mm into the extraction space within 3 weeks as seen in cephalometric and periapical radiograph. New alveolar bone was generated and remodelled rapidly in the mesial part of the canine during and after the distraction. It became mature and indistinguishable from the native alveolar bone 3 months after distraction. During distraction, no sagittal movement of the molar was observed.  The radiographic examination revealed that apical or lateral surface root resorption of the canine was minimal. No periodontal defect or endodontic lesion was observed throughout and after distraction. It is concluded that the Dentoalveolar segment of canine could be rapidly distracted without complications. The rapid orthodontic tooth movement through distracting the Dentoalveolar segment cannot be emulated by current conventional orthodontic concepts and methods.

Keywords: Canine retraction, Dentoalveolar distraction.
