The purpose of this review is to conduct a detailed analysis of the literature on the use of myofunctional oral therapy tools for the treatment of Class II skeletal malocclusions. From March to May 2020, a comprehensive and systematic search was performed on the Medline (PubMed) and Google Scholar databases for works published since January 2010, using the following terms in the search: oral myofunctional tools; Class II skeletal malocclusions in children; treatment of class II bone malocclusion in children. Additional manual searches from other sources are also carried out. Only scientific articles in English are considered for this review. An electronic and manual search resulted in the identification of 61 articles. Based on the inclusion criteria, a full text copy of 30 articles was selected for analysis. Specific analysis was then made of 16 articles describing the effects produced using tools to treat Class II skeletal malocclusion and masticatory muscle dysfunction. Literature findings indicate that the myofunctional oral therapy allows the treatment of several problems associated with the development of class II malocclusions. Although therapy induces mainly dentoalveolar changes that result in significant overjet reduction, this therapy also shows a positive effect on masticatory and perioral muscles. This method has been proven effective in obtaining significant corrections for class II skeletal malocclusions.
