Methodology: Observational, descriptive, cross-sectional, retrospective study with non-probabilistic quantitative method. Material and methods: A total of 59 patients who attended the UJAT orthodontic clinic in the period from February to May 2017. Results: The most frequent maxillary opening of the mandible is 45 mm, the most frequent degree of temporomandibular dysfunction is mild.
