The use of finite element analysis is becoming more widespread with rapid advancements in computer technology. However, the field of dentistry is not enjoying the spillover benefits of the expanded use of this design simulation and analysis tool. Finite element modeling requires measurement of the object. However, as the living body is morphologically very complex, this requires a great deal of both time and skill using CAD applications, thus preventing its widespread adoption in the dental field. Although there have been reports of finite element modeling from CT images, these methods require skilled programmers for software development--which is another factor that prevents its widespread adoption in dentistry. Therefore, establishing a finite element modeling method that is both accurate and practical will be of great benefit in clinical dentistry. In the present study, a method using computer tomography and existing software was examined for finite element model construction based on computer tomography images. The results suggested that the method developed here is feasible and practical for clinical use.
随着计算机技术的飞速发展,有限元分析的应用越来越广泛。然而,牙科领域并未从这种设计模拟与分析工具的广泛应用中受益。有限元建模需要对物体进行测量。然而,由于活体形态非常复杂,使用CAD应用程序进行测量既耗时又需要技巧,因此阻碍了其在牙科领域的广泛应用。尽管有从CT图像进行有限元建模的报道,但这些方法需要熟练的程序员进行软件开发,这也是其在牙科领域无法广泛应用的另一个因素。因此,建立一种准确且实用的有限元建模方法将对临床牙科大有裨益。在本研究中,研究了一种利用计算机断层扫描和现有软件基于计算机断层扫描图像构建有限元模型的方法。结果表明,这里开发的方法在临床应用中是可行且实用的。
