Individuals with severe dentofacial discrepancies, beyond the scope of conventional orthodontic treatment (ie orthodontic camouflage), will often require a joint orthodontic-surgical approach to managing their malocclusion.1 This treatment approach, involving a combination of orthodontic treatment with orthognathic surgery, is used to manage severe underlying skeletal and dental discrepancies in the anterior-posterior (AP) (such as severe Class II or Class III malocclusions), vertical (such as anterior open bites and deep overbites) and transverse dimensions (usually involving facial asymmetries and severe crossbites/scissors bites).1 Treatment of this nature is usually started when facial growth has slowed, and timed such that the pre-surgical orthodontics have been completed and patients are ready for surgery, when their growth is significantly reduced or stopped, usually at about 17−18 years in females and over 18−19 years in males.2 However, it is prudent for orthodontists to assess each patient individually, sometimes with growth charts, as growth patterns vary and these timings may not be correct for all patients.2
