Sažetak
The aim of this study was to investigate the stress distribution in a 3-D model of two-rooted tooth (first maxillary premolar)
under two different occlusal force vectors by using finite element analysis. In the first model overall force of 200 N
was divided into three vectors (cusp to fossa occlusion), and in the second model overall force was divided into 4 vectors
(cusp to fossa and cusp to marginal ridge occlusion). The greatest compressive stress was found at the dentino- enamel
junction in the cervical area of the both models (about –200 MPa). The greatest tensile stress was found at the vestibular
aspect of buccal cusp in second model (about +3 MPa) and in the central fossa of the both models (about +28 MPa). Results
indicate that in the both types of occlusal loadings the stress distribution was mainly compression and compressive
forces were predominant over tensile stresses. In the second model with 4 vectors, stresses generated in the tooth structure
were higher compared to the stresses generated in the first model with 3 vectors.
