Molar intrusion vs maxillary surgical impaction in skeletal open bite patients: Systematic review

Abstract

Objective: Skeletal openbite’s control, is an effective challenge in orthodontics. In adults, treatment of severe skeletal open bite consists mainly of surgically repositioning the maxilla or the mandible. Recently, molar intrusion by using skeletal anchorage has been developed as a new strategy for open-bite treatment. The aim of this research is to compare the effectiveness of 2 approaches: Molar intrusion Vs surgical impaction in skeletal open bite’s control through a systematic review. Material and Methods: A search of the literature was performed in the following data bases: PubMed, Science Direct, Cochrane library. The search was limited to publications written in english and french from 2010 to 2021 Results: Out of 83 references initially identified, 12 corresponded to our inclusion criteria. These studies have looked at molar intrusion using skeletal anchorage or surgical impaction of the maxillary with or without mandibular osteotomy in the treatment of skeletal open bite. These studies have reported an increased incisal coverage, decreased lower facial height, counterclockwise rotation of the mandible, and a satisfactory stability of results. Conclusion: The intrusion of molars using implant anchorage seems to be the most rational therapeutic procedure for skeletal open bite patients offering satisfactory skeletal and dento-alveolar results.
