Correction of open bite with temporary anchorage device-supported intrusion

Abstract

This case report describes the use of temporary anchorage device (TAD)-supported molar intrusion to correct anterior open bite and achieve overjet correction. A 13-year-old female presented with a Class II skeletal profile, with increased overjet and anterior open bite. She was treated with a combination of intrusion of the posterior teeth and extrusion of anterior teeth. The intrusion of maxillary posterior teeth was done with a palatal TAD and a transpalatal arch on the upper first molars to control the transverse dimension. The patient’s mandibular plane angle was maintained with this treatment approach.
