Class III malocclusion treatment is a daunting challenge for Orthodontics. In growing patients, the treatment procedure chosen for this malocclusion is maxillary expansion followed by reverse traction performed by means of a face mask. According to the literature, the ideal age range for patients undergoing this type of treatment is between 7 and 8 years old. At this age, it is possible to achieve better orthopedic results in comparison to dental efects. Nevertheless, patient’s age may vary. Therefore, what is the ideal treatment approach for adult patients? Would it include maxillary expansion and protraction, Figure 1 – Measurements used: A) angular and B) linear. (Source: Halicioglu et al,1 2014) A B as in younger patients, or protraction with face mask, only? According to Halicioglu et al,1 no study has been conducted to assess these treatment methods having adult patients as target. Thus, the authors conducted a study in which they assess the efects of protraction of the maxilla (alone and associated with palatal expansion) on treatment of young adults with maxillary retrognathism (Fig 1). Their results reveal that palatal expansion before maxillary protraction by means of a face mask does not enhances the efects of the former in young adult patients. Such outcomes are important, since they suggest that the use of face mask could start earlier without the need for previous maxillary expansion, thus taking advantage of the last months of maxillomandibular growth.
