Class III malocclusion is associated with a maxillary retrusion, a mandibular protrusion, or a combination of both. This type of skeletal disharmony, almost always, requires an early intervention, since it generates a disharmony that is very unpleasant to the wearer. Thus, this dissertation is composed of two articles that had as objectives: (1) to carry out a systematic analysis of the literature about the treatments for Class III malocclusion; (2) from the creation of a technological tool to support planning based on artificial intelligence, called "Orthodontic Planning" (OP), to evaluate the degree of agreement of the treatment plan proposed by orthodontic specialists with the suggested treatment plan By OP; (3) to analyze the interest of orthodontists participating in this new technology. In study 1, the scientific literature was searched using the PubMed search platform and the Cochrane Library, generating 25 articles, being 17 randomized clinical trials and 8 systematic reviews. In the study 2, 40 orthodontic specialists, representing the sample of orthodontists from Fortaleza-CE, randomly chosen, were invited to elaborate a treatment plan for three previously selected clinical cases, generating 120 analyzes. Then the data of the respective patients were entered into the application to obtain the suggestion of treatment offered by the OP. At the end of this stage, the orthodontist indicated whether he totally agreed, partially or did not agree with the planning issued by the software. The level of concordance was statistically analyzed by the Pearson Chi-square test, with a significance level of 5%. The literature review presented in article 1 showed that maxillary traction facial mask is the main therapeutic modality for the correction of Class III malocclusion in patients in the growth phase, but several other devices with more favorable aesthetic characteristics have been used With similar results. In patients who have already ceased growth and did not opt ​​for orthognathic surgery, absolute anchorage through mini-implants and miniplates has been used, achieving more effective treatments and a shorter time interval. The results of article 2 showed that the level of agreement between the treatment plans suggested by orthodontic specialists and the treatment plans suggested by the OP were quite high when compared to each other. Thus, it can be affirmed that this new technological tool serves to assist the professionals specialized in orthodontics in the elaboration of the treatment plan for cases of Class III malocclusion.
