| Objective: The aim of this study is to evaluate the effectiveness of piezocision technique during rapid canine retraction. Materials and Methods : Material of the study consisted of ten patients of both genders, with age ranging from 16 to 25 years with malocclusion that require extraction of first premolars followed by canine retraction. Before starting canine retraction, maximum anchorage was ensured by placing mini-screws 10 mm in length and 1.6 mm in diameter between the second premolar and the first molar. In the experimental group, two vertical incisions were made on the buccal aspect mesial and distal to the canine. Piezo electric knife was used to create cortical bone incisions to a depth of 3 mm. Canine retraction was performed on both sides using nicklel-titanium closed coil springs with force of 150 gm. Scanned casts were used to evaluate canine retraction movement on both sides. Results: On comparing the two sides at the same time, it was found that there was a significant difference between both sides. It was found that the test side was significantly decreased more than the control side. Conclusion: Piezocisionfacilitated orthodontics is an effective treatment alternative that decreases the time required for canine retraction. | ||||
