Facemask Class III Orthodontic Treatment

By on 7-03-2012 in Appliance

A Class III malocclusion can be manifested by different skeletal and dental configurations such as maxillary retrognathism, mandibular prognathism or a combination of the two relationships. Majority of the developing Class III skeletal pattern would have a maxillary defficiency with a normal or a slightly prognathic mandible.

Orthopedic facial mask may provide the greatest opportunity to correct a Class III malocclusion identified in either the late or early permanent dentition. Treatment effects produced by facemask therapy are maxillary skeletal protraction, 1 – 2 mm of forward movement of the maxillary dentition, lingual tipping of lower incisors, and redirection of mandibular growth. There are 2 types of design of the facemask: Delaire’s and petit’s.

Components of petit’s facemask include a single midline rod connected to a chin pad and forehead pad and elastics connected to an adjustable crossbow. Intraoral appliance on the maxilla may be banded with maxillary expansion appliance, bonded to the posterior dentition or incorporated in a removable appliance. Maximum force is delivered through the use of 5/15″ elastics that are rated at 14 oz of force. It must be worn for 14 – 20 hours a day for 4 – 6 months or until a positive overjet is achieved intrinsically.
