Objective To discovery the stress distribution in bone around the implant of middle implant-teeth fixed bridge under different loading. Methods The model was set up by 3-D finite element means. The stress in bone around the implant under loading was computed by finite element analysis software Super-SAP 93. Results The biggest stress in bone around the implant lied in the neck cortex of bone. The biggest stress in bone around the implant under concentrated oblique loading was 2.5 times as big as that under concentrated vertical loading. The peak value of tensile stress lied in the boundary of lingual cortex of bone under concentrated vertical loading. The biggest compressive stress was higher than the biggest tensile stress under concentrated loading. Conclusion It is important not only to absent abnormally high occlusal points, but also to reduce side direction force for arrangement of natural teeth, middle implant, and fixed bridge into balanced occlusion.
