Class II dento-skeletal disharmony does not self-correct with growth and there is an aggravation of the deficiency of the total mandibular length and the height of the mandibular ramus from the pre-puberty stage to post-puberty; however, there are slight changes in the craniofacial growth of patients from late puberty to adulthood. Within these disharmonies, class II division 1 is considered by many authors as the most frequent. Functional maxillary orthopaedics is an area within dentistry that seeks to prevent, intercept, and treat dento-maxillo-facial and postural disorders of growing patients, and to solve problems that occur in the functions of the stomatognathic system by correcting malocclusions and maxillomandibular anomalies in the three directions of space: transverse, vertical and sagittal. The objective of this research is to determine and clarify the real influence that functional devices have on the stomatognathic system of patients in class II division 1. A search was carried out through PubMed with the Mesh terms: “retrognathia”, “malocclusion, angle class ii” and “orthodontic appliance, functional” along with the Boolean term “and”. These terms were noted in the PubMed tool, Clinical Queries. For this study, a total of 59 articles were used. Functional appliances direct and enhance growth to correct or improve malformations of the stomatognathic system. The changes produced by activators in class II division 1 patients include favourable effects on skeletal, articular, dentoalveolar and soft tissue structures.  (Rev Esp Ortod. 2020;50(2):2-063-074)
