An Overview of the Surgical Correction of Dentofacial Deformity

The correction of severe dentofacial discrepancies involving a combination of orthodontic and surgical therapies (termed ‘orthognathic treatment’) is commonplace. There is an abundance of evidence within this field but it is often inconsistent. This article is an evidence-based overview of such treatments and is aimed at the general dental practitioner. It will cover: the timing of treatment; the indications and risks associated with different surgical osteotomies; the magnitude of surgical movements that can be achieved with these procedures; and the importance of mandibular autorotation when planning treatment. Orthognathic treatment is considered to be the gold standard for comprehensive correction of severe dentofacial discrepancies. It is undertaken by a multidisciplinary team of clinicians involving, but not exclusive to, consultants in orthodontics and oral and maxillofacial surgery in secondary and tertiary medical centres throughout the United Kingdom.
