Efficiency of Microosteoperforation for Accelerating Posterior Segment Intrusion in Skeletal Open Bite Cases

This clinical trial aimed to assess the efficiency of micro-osteoperforation for accelerating posterior intrusion in open bite cases. A human sample of thirty subjects was divided into two groups ; Group I (MOP), posterior intrusion with micro-osteoperforation (MOP) and group II (Control), same intrusion protocol without micro-osteoperforation.

Inclusion Criteria: * Clinical anterior open bite involving the incisors and canines ranging from -3 mm to -8 mm * Skeletal open bite confirmed by pretreatment cephalometric angular and linear measurements. * Maxillary posterior vertical dentoalveolar excess guided by the analysis of Burstone et al. * Normal incisor display at rest and during smile. * Non-growing postpubertal adolescent and adult patients with CVM 6 according to Baccetti et al. * Full set of permanent dentition regardless of third molars. * Good oral hygiene. Exclusion Criteria: * Skeletal Class III cases. * Patients suffering from any systemic diseases or congenital anomalies affecting bone. * Patients with previous orthodontic treatment.
