Modified laceback for canine retraction

Effectiveness of laceback ligatures on maxillary canine retraction.

OBJECTIVE To evaluate the effects of laceback ligatures on canine distalization during the leveling and aligning stage and to compare the effectiveness of laceback ligatures with that of superelastic NiTi closed coil springs. MATERIALS AND METHODS Fifteen subjects were included in this study. Fixed orthodontic treatment was planned with the extraction of first premolars to solve crowding in u...

a new method for rapid canine retraction

distraction osteogenesis method (do) in bone lengthening and rapid midpalatal expansion have shown the great ability of osteognic tissues for rapid bone formation under distraction force and special protocol with optimum rate of one millimeter per day. periodontal membrane of teeth (pdm) is the extension of periostium in the alveolar socked. orthodontic force distracts pdm fibers in the tension...

Rapid canine retraction

Introduction: Rapid canine retraction through distraction of the periodontal ligament is a tooth movement technique that allows space closure of first premolar extraction space within a period of two to three weeks while providing significant reduction in orthodontic treatment time. Objective: To propose changes in the original surgical technique and in the placement of distractors. Conclusions...

Dento-Alveolar Distraction Osteogenesis for rapid Orthodontic Canine Retraction.

BACKGROUND The objectives of this study were to evaluate the rate of canine distalization by segmental alveolar distraction method in first premolar extraction cases, to evaluate the displacement of the canine and first molar teeth, to assess the effects of the procedure on the pulpal vitality of the canines, and to determine the amount of root resorption in retracted canines. MATERIALS & MET...
