ABSTRACT

Introduction: we have observed in our orthodontic practice a large number of patients with inclined occlusal plane, with a high goniac angle and posterior mandibular rotation. Everything seems to indicate that the occlusal plane plays a very important role in the development of malocclusions. Objective: to show in the present clinical case of a child, if there is a correlation between the inclination of the occlusal plane, the height of the goniac angle, the length of the mandibular branch and the projection of the chin before and after, when correcting it and making it more horizontal with orthodontic treatment. Case report: an 11 year old male patient, hyperdivergent, severe skeletal class II, convex profile, upper and lower dental crowding, molar class II, severe labial incompetence, deep bite, increased overjet, retrusive chin, rectified cervicals, and anterorotation of the head. Orthodontic treatment was performed with Roth slot 22 brackets and extractions of upper and lower first premolars and upper first molars (being replaced by upper third molars), inverse curve, space closure with loss of anchorage and occlusal adjustment. Results: at the end of the treatment, it was possible to improve facial aesthetics, a more developed gonial angle with greater vertical growth, greater chin projection, a more horizontal occlusal plane, an adequate overbite and overjet, molar and canine class I, mandibular anterorotation, good intercuspidation, functional occlusion and excellent occlusal stability without retention, improvement in cervical lordosis and head position. Conclusions: the correction of an inclined occlusal plane in hyperdivergent children and adolescents can significantly improve the growth vector, help further development in the height of the gonial angle and length of the mandibular ramus, chin protection when correcting it and making the most horizontal occlusal plane with the orthodontic mechanics of inverse curves; therefore, in the present clinical case: there is a very important correlations between the inclination of the occlusal plane, the height of the gonial angle and chin projection before and after orthodontic treatment.
