Relationships Between Anterior and Condylar Guidance - Comparison by CBCT and Electronic Axiography

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.

About this study

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.

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • 20-24 years old

Exclusion criteria

  • history of trauma, orthodontic treatment or temporomandibular disorders

Treatment and study plan

CBCT

Radiation
