A 3D finite element model of the mandible dentition was developed, including 14 teeth, a periodontal ligament (PDL), and splint made polymethylmethacrylate (PMMA). The study considered three design options: 1—the case absence; 2—the presence installed after manufacture; 3—the correction (grinding) performed to ensure uniform distribution occlusal force between teeth. For cases absence splint, measurements functional load were using T-Scan III software hardware complex (TekScan, Boston, MA,...
