Abstract:
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.
