Abstract
Introduction: Class III malocclusions can be treated through various approaches depending on their etiology and treatment objectives. The use of miniscrews for distalization of the mandibular arch has been previously reported with favorable outcomes. Objective: To correct a unilateral Class III malocclusion and anterior open bite using a mandibular shelf miniscrew with asymmetric force application. Case presentation: A 23-year-old female patient presented with Class III malocclusion on the left side, Class II on the right, an anterior open bite, and a dental midline deviated to the right. She had a history of previous orthodontic treatment. Conventional metal brackets were placed, and distalization of the lower left segment was performed using a mandibular shelf miniscrew, sliding jigs, and power chains. The total treatment duration was 1 year and 8 months. Conclusions: The distalization mechanics were effective in establishing bilateral Class I molar and canine relationships, correcting the anterior open bite, and achieving midline coordination. Unilateral miniscrew anchorage in the mandibular shelf represents a reliable option for managing Class III malocclusion with anterior open bite and midline deviation, while reducing the need for patient cooperation and avoiding extractions.
