| Abstract | ||
| Purpose: This split-mouth trial was designed to assess how Micro-OsteoPerforation (MOP) affected maxillary molar distalization. Material and Methods: This study included sixteen patients with bilateral Class II molar relationship requiring non extraction treatment with bilateral maxillary molar distalization. In the study, a split-mouth design was adopted. A bone anchored pendulum appliance (BAPA) was used for distalization. MOP (the experimental group) was assigned randomly to one side of the maxillary arch, though the other side acted as a control. Three MOPs were carried out distal to the upper first and second molars just prior to starting distalization using Propel at 3, 6, and 9 mm from the alveolar bone crest and all were 5 mm in depth crossing through the cortex and entering the spongious bone. Data were collected from pre- and post-distalization CBCT and digital models. Results: Comparing the MOP sides to the control sides, the overall distalization duration was noticeably shorter on the MOP sides (P=0.042). On the contrary, the total distance moved by the maxillary first molar showed no significant difference between the two sides. All CBCT variables showed that neither side was significantly different from the other except the U1-PTV which showed more palatal movement of the upper incisors in the MOP sides than the control sides (P=0.006). Conclusions: MOP can be an effective method for accelerating molar distalization as it shortens the total duration of distalization. | ||
