Finite element analysis demonstrates reduced stress and strain concentrations in square dental implants, indicating superior biomechanical stability compared to V-shaped designs.
A BSTRACT Background: One emerging and important research method for biomechanical assessments in biological investigations is the finite element analysis (FEA). It is the best technique for simulating intricate structures and examining their mechanical characteristics. Aim: This study was conducted to compare the V-shaped design and square thread design regarding their influence on the stress and strain distribution using the finite element method. Methods and Materials: Forty dental implants with two different designs were used. These designs were V-shaped design and square design. Utilizing Creo 2.0, cortical bone, cancellous bone, and implants were modeled. FEM analysis was performed on forty model assemblies. Results: It was observed that mean load 1 values for squared thread design were lesser as compared to V-shaped thread design at coronal one-third middle one-third and apical one-third in the cancellous bone as well as implant surface. Conclusion: The design of implant is an important factor influencing the stress and strain distribution using the finite element method with a square design showing reduced concentration.
