Searches were executed in PubMed and BIREME databases. For both, MESH and DeCS, the terms of vocabulary with the following Boolean connectors are used: Maxilla OR Retrognathia OR Malocclusion Angle Class III NOT Malocclusion Angle Class II AND Orthodontics. Two terms were used to differentiate the degree of verifiability and repeatability of the selected items: these terms were “Prove” and “Demonstrate”. The first term is applied to therapies that have a single randomized controlled trial and the second term for therapies that have two or more. In this way the plate progeny, twin block reverse, the chin cup and the arch tandem have proof of their effectiveness (one randomized controlled trial), but the facial mask has degree of demonstration (four randomized controlled trials). Regarding efficiency, the facial mask obtained results at nine months with 14 hours of daily use. Therefore, the face mask should be the treatment of first choice for patients with mixed dentition maxillary deficiency.  (Rev Esp Ortod. 2016;46(2):065-070)

Key words:
Angle class III maolccusion. Retrognathia. Maxilla.
