NCT05637372

Brief Summary

The aim of the following study was to investigate the existence of a statistically significant correlation between the incisal features (incisal guidance angle, interincisal angle, overbite, overjet), temporomandibular joint (TMJ) morphology and its function. The hypothesis was: I. The protrusive movement of the mandible does correlate with the TMJ anatomy. II. The protrusive movement of the mandible does not correlate with the incisal features. III. The position and relationship of upper and lower permanent incisors do not have a direct and significant effect on the TMJ morphology in young adults.
