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.
背景
有限元分析（FEA）是生物研究中生物力学评估的一种新兴且重要的研究方法。它是模拟复杂结构并检查其力学特性的最佳技术。
目的
本研究旨在使用有限元方法比较V形设计和方螺纹设计对应力和应变分布的影响。
方法和材料
使用了40颗具有两种不同设计的牙种植体。这些设计为V形设计和方形设计。利用Creo 2.0对皮质骨、松质骨和种植体进行建模。对40个模型组件进行了有限元分析。
结果
观察到，在松质骨以及种植体表面的冠部三分之一、中部三分之一和根尖三分之一处，方螺纹设计的平均载荷1值低于V形螺纹设计。
结论
种植体的设计是使用有限元方法影响应力和应变分布的一个重要因素，方形设计显示出应力集中降低。
