Abstract
lntroduction and purpose: The morphofunctional relationship between the masseter muscle (MM) and the occlusal plane hasn't been investigated in depth. The main goal of the present study is to prove that the fibres of the MM are located prependicularly to the occlusal plane. Methods: We have evaluated the relationships between the superficial portion of the MM and the position of the incisors, first lower molar, occlusal plane and the Francfort plane, from tele-radiographs of 21 healthy voluntaries, on whom we had placed an intraoral silicone guide for identifying the MM. Results: The angle that the fibres of the superficial portion of MM formes with the occlusal plane is very variable, from 70 to 90°, with a range of 29°. The average is 80,7°. With the Francfort plane, we had obtained an average of 65,8° with a range of 31,5º. Conclusions: The fibres of the superficial portion of the MM do not run perpendicular to the occlusal plane.
