Digital workflows have revolutionized dentistry, especially when it comes to fabrication of complete dentures through Computer-Aided Design and Computer-Aided Manufacturing (CAD-CAM) procedures. Digital articulators manage to simulate mandibular movements and are emerging as alternatives to mechanical articulators like the Gerber semi-adjustable model. Despite being a promising tool, digital articulators require refinement in order to grant consistent functionality and effective occlusal balance. The aim of this research is to present a semi-automated MATLAB tool designed to compare trajectories from different articulator types-digital versus analog-used in dental practice. Validation of the MATLAB tool compared to existing data demonstrates its reliability and effectiveness. Sensitivity analyses assess the tool's robustness under various settings. Results suggest optimal input parameters and settings ensuring precision. Future developments may include integrating anatomically-based reference systems and advanced metrics for rotational analysis of condylar path elements (CPEs), thereby enhancing digital dentistry potentialities. Ultimately, the semi-automated MATLAB tool represents a significant step towards improving dental occlusal analysis, bridging the gap between analog and digital methodologies and enabling comparison among these tools.
数字工作流程彻底改变了牙科领域，尤其是在通过计算机辅助设计和计算机辅助制造（CAD-CAM）程序制作全口义齿方面。数字牙合架能够模拟下颌运动，正逐渐成为像格伯半可调模型这样的机械牙合架的替代品。尽管数字牙合架是一种很有前景的工具，但仍需要改进以实现一致的功能和有效的咬合平衡。本研究的目的是展示一种半自动的MATLAB工具，该工具旨在比较牙科实践中使用的不同类型牙合架（数字牙合架与模拟牙合架）的轨迹。与现有数据相比，对MATLAB工具的验证证明了其可靠性和有效性。敏感性分析评估了该工具在各种设置下的稳健性。结果表明了确保精度的最佳输入参数和设置。未来的发展可能包括整合基于解剖学的参考系统和用于髁突路径元素（CPE）旋转分析的先进指标，从而增强数字牙科的潜力。最终，这种半自动的MATLAB工具代表了在改善牙齿咬合分析方面迈出的重要一步，弥合了模拟和数字方法之间的差距，并实现了这些工具之间的比较。
