目的：探讨植入扭矩值对种植体初期稳定性的影响，并探索达到种植体初期稳定性值的最佳植入扭矩范围。方法：选取六条纯种比格犬，拔除双侧下颌前磨牙和第一磨牙。拔牙术后3个月，于双侧下颌一共植入48枚XIVE种植体。根据种植体的最大植入扭矩值（ITV）将种植体分为4组：A组12枚，0＜ITV ＜20N cm；B 组12枚，20≤ ITV ＜40 Ncm；C 组12枚，40 Ncm ≤ ITV ＜60 Ncm ；D 组12枚，ITV≥60Ncm。种植体植入后立即测量该种植体的稳定性值（ISQ）。结果：A组与B组、C组、D组之间ISQ值有统计学差异（P＜0．05）；B组、C组、D组之间ISQ值无统计学差异（P＞0．05）。结论：根据本研究，只要植入扭矩值达到20Ncm以上，种植体都能取得良好的初期稳定性。植入扭矩值不能全面反映影响种植体初期稳定性，应联合种植体稳定性系数（ISQ值）才能更全面地评估种植体的初期稳定性。

Objective To investigate the correlation between the insertion torque values and primary stability of dental implants using different insertion torque values ,and search for the best insertion torque values that can acquire good primary stability. Methods Six male pure beagles were selected, and the first molars and four premolars of bilateral mandibulars were extracted. Three months later, a total of 48 XIVE dental implants were inserted. All implants were divided into group A, group B, group C, and group D based on the insertion torque value (ITV): group A, 0 < ITV < 20Ncm; group B, 20 ≤ ITV < 40Ncm; group C,40Ncm ≤ ITV < 60Ncm;group D,ITV≥60Ncm The dental implant stability was measured by Resonance frequency analysis when implanrs were placed immediately. Results No complications occured.There was significant difference between group A and grop B (P=0.012), group A and grop C (P=0.037), group A and grop D (P=0.001). There are no ignificant difference among group B,group C and grop D(P>0.05). Conclusion With the limitations of the study, it was concluded the primary stability does not simply depend on the insertion torque;When the insertion torque value was no less than 20Ncm, the dental implant can acquire good primary stability.
