科学领域:

  • 数字牙科数字牙科
  • 计算机辅助设计 (CAD) 软件
  • 3D建模和打印3D建模和打印

背景情况:

  • 越来越多的牙科软件需求需要精确的研究.
  • 有限的比较研究存在于通用 (G-CAD) 与牙科特定 (D-CAD) 软件应用程序之间.
  • 了解软件准确性对于推动数字牙科的发展至关重要.

研究的目的:

  • 为了研究G-CAD和D-CAD软件的数字印记之间的精度差异.
  • 为了比较特定的牙科CAD软件与一般CAD应用程序的精度.
  • 解决有关各种牙科软件的应用和准确性的知识差距.

主要方法:

  • 将一个字体数字化并将模型导出到四种软件类型 (MeshMixer,Exocad,Blender,InLAB).
  • 通过3D打印实现STL文件的物质化,然后再扫描以创建新的STL文件.
  • 使用3D分析软件 (Geomagic Control X) 的六组模型进行比较,并进行最佳合适叠加.

主要成果:

  • 在四种软件类型中没有发现统计学上显著的准确性差异.
  • 一个D-CAD组合 (Blender-InLAB) 显示了最高的平均精度 (-0.0324).
  • 一种通用/特定软件组合 (Meshmixer/Blender) 的平均精度最低 (0.1024).

结论:

  • 虽然G-CAD和D-CAD之间没有显著的整体精度差异,但特定的牙科软件组合可以产生更高的精度和真实性.
  • 该研究在使用D-CAD软件的组中发现了更大的耐受性.
  • 进一步的研究可能会探索针对最佳数字牙科工作流程的特定软件组合.
