Dental occlusion
Conditions
Interventions
Twelve subjects will be recruited and divided into six groups with two subjects in each group: in Group 1, a laterotrusive interference will be adhered on the side of masticatory preference (ILU)
in Group 2, two bilateral laterotrusive interferences, both in left and right laterality (ILB)
in Group 3, a mediotrusive interference on the side of masticatory preference (IMU)
in Group 4, two bilateral mediotrusive interferences (IMB)
in Group 5, two bilateral protrusive interferences (PI)
and in Group 6, two false interferences (dummy). The chewing preference side will be observed by chewing gum. After the initial experimental day, each member of each group will go through all phases a

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected that the presence of occlusal interference causes changes in mandibular movement and muscle function, with modification of the stomatognathic system, with alteration of masticatory performance. Patients with mediotrusive interferences will have more impairment in masticatory performance compared to subjects with laterotrusive interferences. | — |
