Abstract
Aim: It was to evaluate efficacy of modified corticotomy technique (combination between vertical and perforation corticotomy) versus standard vertical corticotomy technique in canine retraction for maxillary dentoalveolar class II malocclusion correction when they were in combination with skeletal anchorage. Patients and methods: 24 patients had maxillary class II malocclusion were treated by skeletal anchorage application combined by corticotomy cuts in one side and alone in another side (control side). Groups were divided randomly into equal groups according corticotomy techniques {group I: vertical corticotomy, group II: vertical and perforation corticotomy (modified corticotomy)}. The upper arch was immediately activated bilaterally after surgical procedure for retraction of the maxillary canines. The patients were followed for 6 months. Statistical analysis was done for the duration of canine retraction, rate of canine retraction, molar anchorage loss, gingival probing depth, and canine root resorption parameters. Results: The control side took significant longer duration than the corticotomy side in all groups. Group I showed statistically significant longer duration for canine movement than groups II. Molar anchorage loss parameter during canine retraction was unsignificant in both groups. Other parameters showed no significant differences between both sides in groups. Conclusion: Modified corticotomy technique is an effective way to accelerate orthodontic tooth movement, with superiority for it than vertical corticotomy in this aspect.
