Molar Intrusion in the Management of Anterior Openbite and ‘High Angle’ Class II Malocclusions: About a Case Report

Anterior open bite is a complex malocclusion that often requires comprehensive treatment due to its multifactorial etiology and high relapse potential. Conventional treatment options such as orthognathic surgery or extraction therapy may have limitations. Recent advancements in skeletal anchorage have introduced miniscrews as a minimally invasive and reliable alternative. This case report illustrates an 18-year-old female with sagittal skeletal Class II pattern, hyperdivergent facial type and class I molar and end-on Class II canine relationship, with an anterior open bite. The treatment plan consisted of using miniscrews placed bilaterally in the posterior maxilla to facilitate molar intrusion. A transpalatal arch was used to maintain transverse stability during the intrusion phase. The approach resulted in effective molar intrusion, closure of the open bite, and an improved facial profile.
