ABSTRACT

Introduction: alveolo-dental arcades are constantly changing, which keep the structures in a biological balance due to the influence of multiple factors. When any of them, or several at a time, failed in their objective, an alteration known as malocclusion is produced causing an anatomo-functional imbalance of the whole stomatognathic system.
Objective: to identify possible association between general malocclusions and functional occlusal variables, and their association with functional state of the stomatognathic system.
Methods: a descriptive cross-sectional study was carried out in 100 adolescents aged 15-19 years who had general malocclusions at “José Martí” pre-university from Camajuaní municipality, Villa Clara province.
Results: the most common general malocclusions was dental crowding, followed by anterior edge-to-edge bite, unilateral posterior crossbite, exaggerated overjet and overbite, and open bite; the most associated to dysfunction among them were anterior open bite and unilateral posterior cross bite. There was no significant association between morphological malocclusions and occlusal interferences. Working side interferences predominated in relation to non- working side, posterior area or balancing side ones. There was a low frequency of abnormal slidings of centric relation to maximal intercuspation position in only 27 patients.
Conclusions: the functional occlusal variables significantly associated to general malocclusions were the non- working side interferences, which were also more associated with the dysfunction.
