Abstract: The structure of dental implant is very important to its service life. In order to investigate the effect of the biomechanical properties of anchored dental implant on the osseointegration strength and secondary stability of dental implant, a dental implant model was established based on the three-dimensional structure of human oral cavity, craniomaxillofacial region. Static analysis of dental implant under static load was carried out by using ANSYS finite element analysis software. The results show that the anchorage structure dental implants have better biomechanical compatibility than the traditional standard dental implants, and can improve the strength of the bone-bonding interface. At the same time, the side of the anchorage structure can share the stress of the alveolar bone-implant interface and reduce the risk of unintentional bone-implant damage, so as to ensure the secondary stability of the dental implant, and can better limit the degree of freedom of movement of the dental implant, indirectly promote the restoration of bone-implant injury by reducing the fretting of the dental implant.
