| Abstract Scope |
The high failure rate of early dental implants is linked to excessive bone compressive stress. This study presents a method to quantify bone stress during implant insertion and its correlation with primary stability. Titanium implants with different diameters were inserted into pre-drilled synthetic bone. During the process, insertion torque was measured, and bone strain was measured using strain gauges. Results showed compressive strain peaked in the coronal region and decreased apically. A strong relationship was found between bone strain, insertion torque, and implant stability, with maximum compressive stress at 0.42 MPa, within safe natural bone strength limits. The study concludes that adequate primary stability is achieved for 3.75 mm implants in type D2 bone without causing excessive compression, supporting osseointegration. The proposed methodology offers a reliable way to analyze the level of bone stress during dental implant insertion, potentially reducing early failure rates and enhancing treatment success. |
