In the maxillary first premolar andincisor positions, significant mesialization was observed; however, the changes in the angles of these teeth were found to be insignificant.Conclusion: A mini-screw-anchored pendulum appliance is an effective method for maxillary molar distalization that controls theundesired anchorage loss observed in conventional methods.

Özet

Objective: The aim of this study was to evaluate the dentoalveolar and dentofacial effects of a mini-screw-anchored pendulum ap-pliance in maxillary molar distalization.Methods: Twenty patients with the Angle Class II molar relationship (mean age 14.05±2.4 years) were treated with a mini-screw-anchored pendulum appliance for molar distalization. A mini-screw 1.9 mm in diameter and 9 mm in length was used to supportthe pendulum appliance. The springs of the pendulum appliance were activated at 90° and exerted 250-300 gr force per side. Lateralcephalometric radiographs and dental cast models were obtained from all the patients before and after maxillary molar distalization.Results: A 0.6° increase in the SNA and SNB angles, and a 0.3° decrease in the SN/GoGn angle were found to be statistically significant. Inthe maxillary first molars, 4.2-mm significant distalization, 0.6-mm significant intrusion, and 8.9° significant distal tipping were observed.The spontaneous distal drift of the maxillary second premolars was found to be statistically significant. In the maxillary first premolar andincisor positions, significant mesialization was observed; however, the changes in the angles of these teeth were found to be insignificant.Conclusion: A mini-screw-anchored pendulum appliance is an effective method for maxillary molar distalization that controls theundesired anchorage loss observed in conventional methods.
