Abstract
The aim of the research is to analyze the distribution of occlusal vertical forces of the abutment teeth in bridge constructions with slightly shortened dental arches.
Material and method. Subject of research are bridge constructions in slightly shortened dental arches in the mandibula. The Finite Element Method (FEM) was applied,
and the analysis was made with simultaneous both-sided loading on the distal three abutment teeth. The simulated loading forces are with strength between 0.5 to
512N. Distributed occlusal vertical forces are measured at the level of the periodontal ligament (PDL). Results. The results show a symmetrical distribution of forces
on both sides of the bridge structure. The largest forces are distributed on teeth with applied force. The smallest forces are distributed in the apical part of PDL. There
was no difference between the total distributed forces on teeth and the distributed forces on the lateral part of the PDL. The measured strength of the forces and the
percentage are within the known values in the literature. Conclusion. The obtained results of the research are within the level of known functional values of the mastication forces. This means that the biomechanical aspect for bridge constructions with slightly shortened dental arches is not disputable, but the decision to make it should also be based on other individual and clinical conditions.
