Abstract
Objectives: the aim of this study was to evaluate the effect of modified mini-implant aided trans-palatal arch on maxillary molar distalization using CBCT.
Methods: 10 adult patients with Angle class II molar relation were submitted to maxillary first molar distalization using modified mini-implant aided trans palatal arch (MIA-TPA), after completing the essential orthodontic records, CBCT was taken before distalization at T0, then trans-palatal arch (TPA) of 1mm diameter passing anterior on the palate was cemented and 2 miniscrews were inserted between the maxillary 2nd premolar and 1st molar on the palatal side. NiTi closed coil spring was applied between TPA anterior and mini- implant to produce distalization force of 250g/side parallel to the occlusal plane. Dental changes of maxillary molars were compared using cone beam computed tomography CBCT after achieving class I molar relation at T1.
Results: According to the dental linear and angular measurements, the maxillary first molar showed statistically significant bodily distal movement without significant distal tipping. Vertically, the maxillary first molar showed statistically significant intrusion.
Conclusion: MIA-TPA is efficient for bodily maxillary molar distalization movement. Distalization using MIA-TPA produced significant molar intrusion but no vertical skeletal changes occurred.
