Implant structure optimization method based on finite element model

Abstract

The invention discloses an implant structure optimization method based on a finite element model, comprising the following steps: - establishing a full-scale model of the implant implant structure to be analyzed, and using sample point definitions to create a finite element model; - using a Latin hypercube Sampling method LHD points are evenly distributed in the design space, so that the minimum distance between the experimental points is maximized; - use LHD as the sampling method, and set multiple sampling points, and establish a support vector machine regression model SVR; Line-by-line finite analysis; — approximating the stress response of the implant-bone interface by an SVR model and applying a simulated annealing algorithm to search for optimal results. By establishing the finite element model of the gingival bone and the implant of the terminated object, the SVR model is established by using the LHD design algorithm, and finally the model is verified and optimized. The manufactured implant can be adapted to each implant object. Through 3D printing technology, personalized production can be achieved, which makes the implant more firmly fixed and greatly increases the implantation time.

Description

technical field [0001] The invention relates to an implant structure optimization method based on a finite element model. Involved patent classification number G06 Calculation; Calculation; Counting G06F Electrical digital data processing G06F17 / 00 Digital computing equipment or data processing equipment or data processing methods especially suitable for specific functions G06F17 / 50 Computer-aided design. Background technique [0002] With the coordinated development of dentistry and other disciplines, the structure of implants, especially the thread structure, which was previously neglected, has begun to be paid attention to. The gingiva of implant patients of different ages, genders and physical fitness reflects their own physical fitness, especially It is an intuitive reflection of bone quality. Some young people or people with better bone quality can adapt to implants with higher thread density to obtain more durable implant effects, which can be used for life after impl...

Problems solved by technology

[0003] However, implant objects with older grades or osteoporosis cannot adapt to implants with higher thread density due to their own poor bone density, which is very likely to cause gingival collapse during the implantation process, causing more damage to the patient. big pain
