Abstract
Abstract
Objectives: The present study evaluated the effect of different insertion torque types on stability of tapered implants with knife- edge thread design.
Material and methods: Twenty four Patients were randomly assigned into three groups according to the peak torque value recorded during implant insertion: Group 1: low torque application (<30 N/cm). Group 2: medium torque application (30 < IT < 50 N/cm). Group 3: high torque application (>50 N/cm). Dental implants were evaluated clinically and radiographically. (IT) and (ISQ) values were recorded during implant insertion for each group. ISQ values were recorded also at 3 and 6 months. Crestal bone level were recorded using RVG at baseline, 3months and 6months. Bone density were recorded by CBCT at baseline and at 6 months after surgery.
Results: There was a positive correlation between Overall Torque and stability after 3 and 6 months. A general linear relationship between insertion torque and implant stability. High Torque group showed the higher crestal bone loss and bone density than the other groups.
Conclusion: knife edge threaded design implant showed a satisfactory stability including implants inserted with low torque. High torque group showed the highest stability and increasing in bone density, but also it showed the highest crestal bone loss.
