ABSTRACT Aim: The exclusive aim of this study was to assess flapless corticotomy in orthodontic rehabilitation (rapid) of class I and class II malocclusion cases Materials & Methods: Total 40 patients were finalized for study. Both male and females were included in the age range of 19 to 25 years. Patients those requiring orthodontic correction for their malocclusion class I and class II were approached initially. Fixed orthodontic appliances were planned to be provided for their treatment. Group one has 20 patients who undergone peizocision assisted treatment for correction of class I and class II malocclusion. Group two has 20 patients (control). Simple random technique was used for precise selection of patients without any selection bias. All patients with any underlying bony disorders, systemic delinquencies were excluded from the study. Time taken and amount of effective distalization of canine and associated loss of any anchorage was observed carefully to outline the results. P value less than 0.05 was considered significant (p< 0.05). Statistical Analysis and Results: Statistical analysis was completed by using statistical software Statistical Package for the Social Sciences. The mean distalization time for Group I was 3.62 while it was 4.90 for Group II. P value was highly significant for Group I patients. The mean distalization amount for Group I was 1.38 while it was 0.62 for Group II. P value was highly significant for Group I patients. For anchorage loss in group I, the mean value was 2.68 and for group II it was 4.12. p value was highly significant for group I. Conclusion: Authors concluded that orthodontic treatment assisted with piezocision techniques is highly valuable since it offer sufficient distalization in lesser time with minimum anchorage loss. Therefore, this technique can be utilized as and when required in the indicated situation so as to achieve acceptable results.
