Planting body structure optimization method based on finite element model

Abstract

The invention discloses a planting body structure optimization method based on a finite element model. The method comprises the following steps that a full scale model of a planting body structure to be analyzed is established, and the finite element model is defined and created by utilizing sample points; a Latin hypercube sampling method is used for uniformly distributing LHD points in a design space to make the minimum distance between experimental points maximized; LHD is used as a sampling method, multiple sample points are arranged, and a support vector machine regression model SVR is established; line-by-line finite analysis is conducted on sampled data; an optimization result is searched through stress response of an SVR model approximate implantation material-bone interface and by applying a simulated annealing algorithm. The SVR model is established by establishing gingiva sclerotin of a terminationobject and the finite element model of a planting body and utilizing the LHD design algorithm, and finally model verification and optimization are performed. The manufactured planting body can adapt to each planting object, personalized production can be achieved through a 3D printing technology, planting bodies can be fixed firmer, and the planting time is greatly increased.

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 gums of implant patients of different ages, genders and physiques reflect their own physiques. Especially the 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 implantation.

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
