| Abstract | ||
| Aim: This prospective clinical study aimed to evaluate the effects of maxillary molar distalization via a skeletally-anchored distal jet appliance assisted with micro-osteoperforations (MOPs) during the orthodontic treatment of Class II malocclusion. Materials and methods: The trial design was a randomized clinical trial. Twenty patients aged 14 to 17 were enrolled from the outpatient clinic of the Orthodontic Department at the Faculty of Dental Medicine, Al-Azhar University, and randomly divided into two equal groups. They received MOPs after activation of the distalization appliance on both buccal and palatal sides or none (control group). The force magnitude utilized was 240 gms per side and activated every four weeks (T1, T2, and T3) for an observation period of 4 months (T4). The primary outcomes of the present study were to assess the rate of maxillary molar distalization and the total amount of distalization throughout the observation period. Maxillary molar rotation, tipping, and extrusion were evaluated as secondary outcomes. Results: The repeated applications of MOPs successfully accelerated maxillary molar distalization, which was statistically significant (P≤0.05) during the first and second months. This significant distalization continued throughout the study's observation period, with a statistically significant rate of movement observed in the MOPs group. Conclusion: Incorporating micro-osteoperforations during maxillary molar distalization via a skeletally-anchored distal jet appliance could substantially accelerate both the rate and the total distance of distalization. | ||
