[Occlusal justification of early treatment of Class III malocclusions]

Authors mostly admit that Class III treatment has more chance of success and stability if it is carried out precociously. Their conviction is primarily based on the use of patient's growth potential. This aspect does not seem to be the main interest of early treatment. The length of the occlusal plane and its impact on mandibular movements (mastication), which can influence growth and maxillomandibular relationships, accounts or even constrains to act as soon as possible. The fundamental objective of early Class III treatment would be the reorientation of the occlusal plane and the rehabilitation of mastication would be the final goal, ensuring an active and physiological result's retention.
