Abstract:

Introduction: Dental contacts during mandibular eccentric movements may vary in number, location and from person to person. Objectives: To study the frequency of contact patterns during laterality and protrusion; to relate if the people who used orthodontic apparatus had interferences during protrusion movement using the Chi Square test. Methods: It was made an oral examination of 40 people (20 males and 20 females), aged from 14 to 44 years. It was used articulation paper to observe the occlusal patterns. Results and Conclusions: In laterality movements the pattern ?canine protected guide? was the most prevalent. When interference was observed in the working side, it was generally on 16, 17, 26 and 27. Total group function seems to be a rare occlusal pattern on both laterality movements. Teeth 13 and 23 had the higher contact frequency during the laterality movements. In the protrusion, the anterior guide was the most common. The people who didn?t use orthodontic apparatus presented lower prevalence of posterior interferences during protrusion. However there was no significant statistical correlation between the use of orthodontic apparatus and the interferences during protrusion movement.
