The early treatment of Class III malocclusion is a challenge for orthodontists around the world. The challenges imposed by Biology are associated with the diiculty to obtain patient’s adhesion to traditional methods of treatment: maxillary disjunction followed by maxillary protraction with facial masks. The search for alternatives to conventional treatment methods suggests that this malocclusion be corrected with intermaxillary elastics supported by skeletal anchoring plates. Despite being widely difused in the orthodontic literature, this method requires further scientiic evidence. Thus, Turkish researchers developed a clinical1 study to evaluate the dental and skeletal efects of Class III malocclusion treatment performed by means of elastics placed in Class III orientation supported by intraoral miniplates (Fig 1), and the use of a facial mask associated with maxillary miniplates (Fig 2). Their results revealed that both protocols are a good treatment option for severe Class III malocclusion. According to the authors, treatment performed with facial mask associated with miniplate is preferable for patients with severe maxillary retrusion and vertical growth pattern. However, for patients with normal growth pattern and retroclined lower incisors, miniplates associated with elastics placed in Class III orientation is a good treatment option. The authors conclude by emphasizing that, in these cases, treatment must be precisely chosen.
