520 _aImplant micromotion can be one of the causes of implant failure. One of the factors affecting micromotion is the implant macrodesign, which includes the implant{u2019}s thread cross sectional design. The aim of this study was to evaluate the effect of the implant{u2019}s thread cross sectional design on the micromotion of the implants in different bone qualities. In this finite element analysis study, four implant models exhibiting four different thread designs (buttress, reverse buttress, v-shaped and square) were created using Solidworks software. Each model was assembled with a superstructure in four models of four different bone qualities resulting in 16 groups. Each group was examined for micromotion under 100N force using ANSYS software. The results revealed that when comparing micromotion in different bone qualities, the lowest micromotion values were observed with D1 bone and the highest values were observed with D4 bone regardless the thread design. When comparing different thread designs, in D1 and D2 bone, the lowest micromotion was observed with v-shaped thread, which was lower than the square thread and the buttress thread was lower than the reverse buttress thread. While in D3 and D4 bone, the lowest micromotion was observed with the square thread, which was lower than the v-shaped and the reverse buttress thread was lower than the buttress thread
