Dentoskeletal changes during maxillary molar distalization using a skeletally anchored appliance

Objectives: The objective of the current trial was to assess the dentoskeletal changes during maxillary molar distalization using a skeletally anchored distal jet (SADJ). Subjects and methods: A prospective clinical trial was carried out to contrast the predistalization and postdistalization cephalograms of 10 patients (4 males, 6 females) (The average age at the beginning of therapy was 15.61±1.03 years) requiring bilateral molar distalization with SADJ and randomly selected from the orthodontic department's outpatient clinic at Al-Azhar University (Boys), Cairo, Egypt's Faculty of Dental Medicine. Results: The trial verified that the device is appropriate for translatory molar distalization (2.9 ± 0.53 mm). The anchoring unit, which consists of two anchorage teeth and two mini-screws, absorbed the majority of the forces operating reciprocally on the anchorage setup. Considerable anchoring loss shown as 0.94± 0.78 mm of first premolar mesialization and central incisors protrusion of 0.83± 0.32 mm were found. Conclusion: upper molar distalization using a skeletally anchored device, such as the distal jet and palatal miniscrews, is a practical and effective method of treating the Class II malocclusion. The skeletally anchored device distal jet can produce a sufficient amount of molar distalization, with minimal effects on the anterior teeth.
