Effect of Relative Height of Planting Denture on Interdental Food Impaction: A Numerical Study

Abstract:

The study about the impact of implant denture on getting stuck between the teeth is rarely reported. Computational modeling and simulation was performed in this study in order to investigate the effect of planting denture on interdental food impaction. Four groups of experiment were designed; Simplified teeth models were established and meshed; loads were applied to the models and boundary conditions were constrained in the state of teeth chewing. Finite element method was employed to analyze the deformation of teeth and impacted object. When the force exerting on the impacted object is in the range of 0-5.5N, the distance between denture and tooth after planting denture is less than that between the normal teeth. The deformation is the minimum when the denture is lower than tooth. When the force exerting on the impacted object is in the range of 0-5.5N, interdental food impaction is easier to occur after planting denture, and Interdental food impaction may be more likely prevented when denture is lower than tooth.
