Résumé
BACKGROUND:Oversize stress of a dental implant and its surrounding tissue is the main factor to affect the long-term use of dental implants. So, the reasonable and precise design of implant shape is one of the important methods of prolonging the life span of dental implants. OBJECTIVE:To make the optimal analysis and design of the diameters of connector screw and central screw of the adjustable-angle dental implant invented in the earlier stage. METHODS: The finite element analysis model of the edentulous mandible with adjustable-angle dental implant was established by software Pro/E 5.0, Mimics 10.0 and ANSYS Workbench 14.5. The maximum equivalent stress of dental implant-edentulous mandibular model was analyzed. RESULTS AND CONCLUSION:The maximum equivalent stress of dental implant-edentulous mandibular model
