Dental occlusion refers to the static and dynamic relationships that are established between the teeth of the two arches and is an important factor in the homeostasis of the dento-maxillary system. The objective of the present study was to compare two digital occlusal analysis systems: the T-Scan III system and the Medit I600 intraoral scanner.
The study was carried out on 20 students from the Faculty of Dental Medicine Craiova, whose dental occlusion was assessed with the T-Scan III system and with the Medit I600 intraoral scanner. Dental occlusion was assessed in the maximum intercuspation position, the edge-to-edge protrusion position, and the edge-to-edge position in right and left laterotrusion. The images of the 2D occlusal contact areas obtained by both methods were converted to .jpeg format and then transferred to Adobe Photoshop CS6 2021 (Adobe Systems, San Jose, CA, USA) for comparison. The recorded data were statistically processed.
Analyzing the data provided by the two digital occlusal analysis systems, it was found that the T-Scan III system provided data related to the amplitude of the occlusal forces, the surface on which they were distributed (the contact surface), the dynamics of the occlusal contacts, and the proportion in which they were distributed at the level of the two hemiarches, and the Medit I600 intraoral scanner performed an evaluation of the occlusal interface of the two arches, highlighting the extent of the contact areas with the degree of overlapping of the occlusal components. Although both methods of occlusal analysis recorded the highest values for the maximum intercuspation position, the results could not be compared.
The two digital systems provide different data in occlusal analysis. As the T-Scan III system is considered the gold standard for occlusal analysis, more studies are needed to understand the data provided by the Medit I600 intraoral scanner and their significance.
牙合是指上下牙弓牙齿之间建立的静态和动态关系，是牙颌面系统稳态的重要因素。本研究的目的是比较两种数字牙合分析系统：T-Scan III系统和Medit I600口腔内扫描仪。
对克拉约瓦牙医学院的20名学生进行了研究，用T-Scan III系统和Medit I600口腔内扫描仪评估他们的牙合情况。在最大牙尖交错位、前伸对刃位以及左右侧方对刃位评估牙合情况。通过两种方法获得的二维牙合接触区域图像转换为.jpeg格式，然后转移到Adobe Photoshop CS6 2021（美国加利福尼亚州圣何塞的Adobe系统公司）进行比较。对记录的数据进行统计学处理。
分析两种数字牙合分析系统提供的数据发现，T-Scan III系统提供了与牙合力幅度、力分布的表面（接触表面）、牙合接触的动态情况以及在两个半牙弓水平上的分布比例相关的数据，而Medit I600口腔内扫描仪对上下两个牙弓的牙合界面进行了评估，突出了接触区域的范围以及牙合成分的重叠程度。虽然两种牙合分析方法在最大牙尖交错位记录到的数值最高，但结果无法进行比较。
这两种数字系统在牙合分析中提供不同的数据。由于T-Scan III系统被认为是牙合分析的金标准，需要更多研究来了解Medit I600口腔内扫描仪提供的数据及其意义。
