A type of malocclusion which is often found in Thais is Class III malocclusion. Selection of
orthodontic appliances and proper treatment techniques depends on many factors such as characteristics
of malocclusion, age of the patient and genetics. Therefore, orthodontists must be able to recognize
and identify the characteristic of Class III malocclusion that should be treated in the early years. The
proper treatment time also plays an important role in the success of treatment and thus may decrease
the need for orthognathic surgery. This article describes classifications and causes of Class III malocclusion,
indications and contraindications for early treatment, treatment methods and appropriate
treatment time.
