Treatment for Class III malocclusion has been a controversial issue due to the unpredictable growth pattern. According to the literatures, various early interventions have been proposed to modify the skeletal relationship in order to reduce the need for the future complex orthognathic surgery. The influences of the age and the growth potential of patients at the time of treatment were also commonly discussed. Systematic review of the literatures showed that the amount of orthopedic effect was related to the age of patients; however, for those that start treatment before puberty, the stage of the mixed dentition at time of treatment was not relevant to the final result. With proper diagnosis, protraction with facemask resulted in 75% short-term success rates. Yet individual variations did exist, and predictable results were still unavailable currently. On the other hand, studies of chincap treatment with long-term follow up indicated that chincap could only partly alter the direction of mandibular growth but not suppress the mandibular growth per se. The aims of this review are to discuss the treatment methods of Class III malocclusion, the time frame of treatment intervention, and the decision making on early treatment, as well as the treatment effect and stability.
