ABSTRACT Damage to the dental implant–alveolar bone interface is one of the key issues limiting the service life of implants, whereas the periodontal ligament between natural teeth and the alveolar bone provides a flexible cushioning function for the interface. Inspired by the flexible cushioning function of the periodontal ligament, this study comparatively analyses the mechanical properties of the dental implant–alveolar bone interface before and after adding a periodontal ligament‐like flexible composite coating to the implant surface through finite element computer simulations, aiming to investigate the interfacial cushioning effect of the flexible composite coating. The results demonstrate that the flexible composite coating reduces and redistributes the stress at the implant–alveolar bone interface, providing an interfacial cushioning effect. Furthermore, both the application method and thickness of the flexible composite coating influence the interfacial cushioning to a certain extent. This research holds theoretical significance for the development of next‐generation dental implants and offers theoretical support for designing implants with flexible cushioning capabilities.
