Molar intrusion in the management of anterior openbite and ‘high angle’ Class II malocclusions

Abstract

Orthodontic correction of anterior openbite has conventionally involved extraction therapy or an adjunctive maxillary impaction osteotomy. However, bone anchored molar intrusion treatments have been reported in recent years as a less invasive alternative for such patients. This paper describes the concepts and treatment processes involved with mini-implant molar intrusion to correct anterior openbite and reduce patients’ excessive vertical facial proportions.
