To reach this goal, a retrospective search from 1994 to 2019 was carried out in the electronic databases (Pubmed). The terms “Class III malocclusion”, “malocclusion, Angle Class III/therapy” and “orthopedic treatment Class III” were searched. Selection criteria were set to include only randomized trials of Pubmed platform. The articles were independently selected and evaluated by two authors (kappa 0.88), based on inclusion and exclusion criteria. The search strategy resulted in 25 articles, 18 resulting from the Pubmed platform. After analyzing these studies, it was concluded that the treatment of Class III malocclusion in patients still growing has as main therapeutic modality the use of facial mask of maxillary traction. Other orthodontic-orthopedic appliances have been used, but with more dentoalveolar responses. In patients who have already ceased growth and did not chose orthognathic surgery to correct their deficiencies, the approach with mini-implants and miniplates has been used with very positive results, generating excellent treatments and in a shorter time, however there are still few scientific evidences that support the effectiveness of this therapeutic modality.
