Stability of implants was measured by rfa regularly.results there was no significant difference between both groups about stability at all periods and histomorphometry, but isq, bic and ba of experimental group were higher than control group, and isq recovered more quickly in experimental group after loaded.conclusion dual threads design contributes to assure the initial and secondary stability of implants, which is particularly important in poor density bone.

结果 两组种植体在各时期的稳定度差异均无显著性，但在每一时期实验组种植体的稳定度均较对照组高，实验组种植体在负重后稳定度恢复较快，负重3个月后实验组的骨-种植体接触率和种植体周围骨面积均较对照组稍高，但两者差异无显著性。结论双梯形螺纹种植体有利于保证种植体的初期和后期稳定性，应用于低密度骨质优越性会更加明显。
