Abstract

Abstract: Objective: To analyze the stress distribution of splinted all-ceramic crowns for maxillary anterior teeth with horizontal alveolar bone absorption through three-dimensional finite element model. Methods: Healthy adults were taken as the experimental subjects and CBCT was obtained. Computer-aided software like Geomagic studio, Mimics, SolidWorks, and ANSYS were used to model the three-dimensional finite element by uniform reduction of the alveolar bone and periodontal ligament components. Results: Three-dimensional finite element model of all-ceramic crowns of maxillary anterior teeth with horizontal alveolar bone absorption was established. It included 7 components: all-ceramic splinted crowns, prepared teeth, cortical bone, cancellous bone, mucous membranes, pericementum, and pulp. Conclusion: The model is realistic, and the structural characteristics and mechanical parameters of each component are clear. The loading force can be uniformly transmitted to various parts. It can be used in stress distribution analysis.

Key words: Alveolar horizontal absorption, All-ceramic splinted crown, Three-dimensional finite element
