ABSTRACTThe analysis of the clinical and radiographic elements is fundamental part of the adequate orthodontic diagnosis. The interrelation of dental arches, profile, facial biotype and skeletal class, will favor the choice of the most convenient treatment that generates pleasant, functional and stable results in the long term. Objective: Determine if there is association between dental arches with the profile, facial biotype and skeletal class in patients of the Juchimán II Clinic, UJAT. Materials and Methods: An observational, analytical and retrospective study with quantitative method, the sample was selected for convenience, evaluating 120 patients that met the established selection criteria. The dental arch was selected using Orthoform 3MUnitek templates, to obtain biotype Vert analysis was performed by lateral skull radiographs, facial profile with facial convexity angle was determined from profile photographs and skeletal class with Steiner ANB angle. Results. The most prevalent upper and lower dental arches were ovoid. The association between dental arches, profile, facial biotype and skeletal class was determined through the xi2 test, with no statistically significant relationship (p› 0.05). Conclusion. It is concluded that there is no association between the variables studied, because a certain form of dental arch is not specific to any profile, facial biotype or skeletal class. At present there is not yet a universal consensus on this relationship, however, these elements condition the treatment and mark the best way to meet the objectives posed with each patient, so they are indispensable in the correct orthodontic diagnosis.
