Abstract
Protraction facemask therapy has been advocated in early treatment of Class III malocclusions with maxillary deficiency. The dental and skeletal effects of this appliance are well documented in the literature.1-5 One reason that clinicians are sometimes reluctant to render early orthopedic treatment in Class III patients is the inability to predict mandibular growth.6 Patients receiving early orthodontic or orthopedic treatment might need surgical treatment at the end of the growth period. Is it worth the burden to treat a Class III malocclusion early? If so, what type of Class III malocclusions will benefit from early facemask treatment? When is the best time to start treatment? Can early treatment help to predict excessive mandibular growth?
