Myofunctional Dentistry is a treatment that acts in the re-education of facial and masticatory muscles, correcting bad myofunctional habits such as mouth breathing, atypical swallowing and incorrect tongue positioning, directs the growth and correct development of the cranio-cervical-mandibular complex structures and helps in alignment and leveling of teeth in patients of all ages. Myobrace is a myofunctional device of Australian technology that promotes the correction of habits and dental alignment without the use of brackets. The objective of the work was to present a literature review of the Myobrace device. To this end, a survey was carried out in research bases (Medline, Cochrane, Embase, Pubmed, Lilacs and BBO) between the years 2019 and 2020, focusing on randomized clinical studies, prospective nonrandomized longitudinal studies, systematic and meta-reviews analyzes, clinical cases that used Myobrace. As a result, after applying the inclusion and exclusion criteria, articles were found, which were used to carry out this work. It is concluded that orthodontic treatment cannot be considered a contributing factor for the development of temporomandibular disorders.

Introduction: The dental treatment of an autistic patient is the most diffi cult and the patient's collaboration is often lacking. Objective: Thus, the objective of this report is to present a clinical case of a non-collaborating autistic patient in which it is the only viable option for carrying out treatment under general anesthesia in a hospital environment. Case report: Male patient, 24 years old, who was consulted for a dental appointment for the fi rst time to assess the oral cavity. It was observed that there is a need for dental treatment and extractions. The patient was non-verbal, uncooperative and aggressive. Altered behavior control was indicated for general anesthesia for treatment dental care. Result: All dental treatment was performed with the patient under general anesthesia, including prophylaxis with prophylactic masses, a restoration and two extractions in the upper arch and one extraction in the lower arch. Conclusion: General anesthesia allows adult autistic patients not to cooperate to be considered effective and with quality.
