Abstract

The invention relates to an automatic finite element modeling method of a dentognathic system and a system thereof. The method comprises the following steps: 1) setting the number of teeth on the upper and lower jaws and the expansion coefficients of the geometrical models of the upper and lower teeth; 2) according to the number of teeth on the upper and lower jaws, the geometrical models of the upper and lower teeth and a geometrical model of the upper and lower teeth, obtaining a new geometrical model of the upper and lower jaws after digging out a defined number of teeth and parodontium; 3) setting the material attribute data of the teeth, the parodontium and the jaws and the element type and element size of the finite element; and 4) according to the material attribute data and the element type and element size of finite element, dividing the finite elements of the new geometrical model of the upper and lower jaws and the geometrical models of the teeth and parodontium to obtain the finite element models of the upper and lower jaws, the teeth on the jaws and the parodontium. By adopting the method of the invention, the finite element models of the dentognathic system can be generated conveniently and efficiently and the workload of the doctor can be reduced.

Description

technical field [0001] The invention relates to the finite element modeling of the dental and jaw system, in particular to an automatic finite element modeling method and system of the dental and jaw system based on the finite element analysis system Ansys. Background technique [0002] The personalized dental system model is an important auxiliary tool for dentists to analyze the functional defects of the patient's dental system, compare treatment plans, and judge the effect of diagnosis and treatment. The construction of the dento-jaw system model includes the following steps: [0003] 1) CT (Computed Tomography, computerized tomography) and laser scanner are used to scan the dental system to obtain the geometric model of the dental system; [0004] 2) Utilize the geometric model of the jaw to construct the geometric model of the periodontal ligament and the geometric model of the jaw with the teeth and periodontal ligament excavated; [0005] 3) Divide the geometric mod...
