Orthopaedic correction of an anterior cross-bite | Revista Mexicana de OrtodonciaThe worsening of Class III malocclusion increases with age. These include intra- and extra-oral appliances such as a face mask, functional regulator, removable mandibular retractors, splints, Class III elastics, chin cup, and mandibular cervical headgear. The early orthopedic treatment of Class III malocclusions, at the beginning of mixed dentition, prior to growth spurt, provides facial balance, modifies the maxillofacial growth and development, and prevents a future surgical treatment by increasing the stability. According to McNamara and Turley, rapid maxillary expansion RME enhances the protraction effect of the face mask by disrupting the maxillary suture. It is widely accepted that the midface deficient Class III patients should be treated before 7—8 years of age.

Many treatment approaches can be found in the literature regarding orthopedic and orthodontic treatment of Class III malocclusion, including intra- and extra-oral appliances.

The mixed dentition is the developmental period after the permanent first molars and incisors have erupted, and before the remaining deciduous teeth are lost. Phase I treatment is usually done early in this period. Mixed dentition treatment goals often focus on skeletal rather than dental correction. To design a treatment plan, the clinician must understand the growth and development patterns, and the known effects of the chosen treatment modality. Jaw growth affects orthodontic treatment, usually favorably, but sometimes unfavorably.
