摘要：
PurposeThe study aimed to investigate the mechanical effects of the taper position in the abutment hole and the screw taper angles on the implant system and peri-implant tissue using finite element analysis.MethodsFour taper positions (L1, L2, L3, L4) in the abutment hole were established using 3D software and five screw taper angles (30 degrees, 60 degrees, 90 degrees, 120 degrees, 180 degrees) were set.ResultTaper position significantly affects the stresses in the implant system. The 30 degrees and 180 degrees angles (L4 position) showed less stress than other angles.ConclusionElevated taper position and reasonable taper angle are beneficial in reducing the stress in the implant system.
