Abstract

Ojectives: The purpose of this study was to quantify the prevalence of various functional occlusal contact patterns, among dental students. Subjects and methods. Occlusal contacts were examined during lateral excursions from the maximal intercuspal position to the canine-to-canine position in 100 young adults. A combination of 3 common clinical methods was used: a visual examination, articulating paper, and feedback from the participants. Results. Data from 3 classification systems were analyzed: (1) Occlusal contacts on the working side only e canine protected articulation was present in 23,5% of laterotrusions; group function was present in 62% of laterotrusions. Other schemes were present in 14.5% of laterotrusions. (2) Contacts on both the working and the nonworking side. (3) Contacts on the working and nonworking side during both right and left laterotrusion. Nonworking side contacts were present in 27% of the participants. Nonworking side interference was present in 20% of the participants. Conclusions. The prevalence of nonworking side interference found in this study was high percent during lateral excursion
