Abstract

Abstract: Objective: To explore the stress relationship between the attachment of implant overdenture for Kennedy class Ⅰ dentition defect and different bone quality by three-dimensional finite element method. Methods: A finite element model of mandibular first premolar to second molar loss was established. Eight models were constructed according to bone type and attachment type: Locator-Ⅰ, Locator-Ⅱ, Locator-Ⅲ, Locator-Ⅳ, Magfit-Ⅰ, Magfit-Ⅱ, Magfit-Ⅲ, and Magfit-Ⅳ. The stress distribution of each component was analyzed to obtain the maximum von Mises stress value and displacement value. Results: Three-dimensional finite element models of tooth tissue, periodontal tissue, mucoperiosteum, implant, attachment, removable partial denture, cortical bone, and cancellous bone were established. Regardless of the type of attachment and the direction of loading, the maximum equivalent stress values of cortical bone and implant-bone interface in different bone types were Ⅰ<Ⅱ<Ⅲ<Ⅳ, and the maximum equivalent stress values of cancellous bone were Ⅱ>Ⅲ>Ⅳ. When applied vertical force, maximum equivalent stress values of cortical bone, implant-bone interface, and cancellous bone in each type of bone were Magfit model > Locator model, and the opposite in the non-vertical direction. Conclusion: Compared to Locator attachment, Magfit magnetic attachment is more suitable for the osteoporotic bone type.
