The study was based on anatomical and functional measurements of the parameters within the masticatory system. The study group was composed in a way that all the participants (age 20-24) had the temporomandibular joints fully developed and at the same time not yet modified by adaptive processes.
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.
