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.
CPD/Clinical Relevance: It is imperative that general dental practitioners have a good understanding of orthognathic treatment in order to recognize when such treatments are indicated, to inform the patient of possible treatment modalities and to be able to discuss associated risks in order to make appropriate referrals. Since treatment timing and magnitude of surgical movements have a profound effect on stability of the treatment result, these must be carefully considered by all clinicians involved in patient care to minimize relapse potential.
Article
Orthognathic treatment is used worldwide to correct severe dentofacial anomalies with the benefits and risks of these being shown in Table 1. There are a multitude of maxillary and mandibular osteotomies and techniques for repositioning the jaws in three planes of space (Table 2). Some are more commonly indicated than others, some have been modified and refined over time, yet no standardized techniques are practised internationally on any one given procedure. Consequently, one could ask which techniques constitute current ‘best practice’. Much of the available evidence is based on the studies undertaken in the mid 1990s1,2,3 when routine clinical practices, such as intermaxillary fixation (IMF) were rudimentary and research techniques were often flawed by today's standards. Studies tended to lack sample size calculations, randomization processes, homogeneity of the test groups or had retrospective or no control groups.
