Class III malocclusion is a less frequently observed clinical problem than Class II or Class I malocclusion occurring in less than 5 of the US.

Dental malocclusions are classified based on the positioning of the upper and lower molars. Malocclusion is the term for a skewed relationship between the positioning of the teeth with the jaw closed. Fixed appliances are usually used before.

When orthodontic camouflage is not sufficient to correct the malocclusion Orthognathic surgery should be considered. O ptimal treatment of a Class III malocclusion with skeletal disharmony requires orthognathic surgery complemented by orthodontics.
