摘要

问题陈述：基于人工智能（AI）的程序可用于在最大牙间隙位置（MIP）上衔接扫描，或在MIP上纠正衔接扫描的咬合碰撞；然而，人工智能程序确定MIP关系的准确性尚不清楚。目的：本临床研究的目的是评估口内扫描仪（IOS）（TRIOS 5或i700）和程序（IOS或基于AI的程序）对MIP关系准确性的影响：将一名参与者安装在发音器上的模型数字化（T710）。使用 2 种 IOS 系统记录受试者的上颌和下颌扫描结果，分别为 TRIOS 5 和 i700：TRIOS 5 和 i700。扫描重复 15 次。然后，在 MIP 中使用双侧咬合记录对每对重复扫描进行衔接。根据使用相应的 IOS 程序完成的自动咬合碰撞校正，将复制的衔接扫描分为两组：IOS校正组和IOS未校正组。根据基于人工智能程序（咬合查找器）的方法创建了三个分组：AI-关节化组、AI-IOS-校正组和AI-IOS-非校正组（n=15）。在人工智能衔接亚组中，非衔接扫描被导入并衔接。在人工智能-IOS校正亚组中，导入在人工智能-IOS校正组中获得的铰接扫描，并校正咬合碰撞。在经过 AI-IOS 校正的子组中，导入了 IOS 未校正子组中获得的衔接扫描，并校正了咬合碰撞。在每个衔接扫描（Geomagic Wrap）上共计算了 36 个地标间测量值。以参考扫描计算的距离为参照，计算与每个实验扫描的差异。采用非参数双向方差分析和成对多重比较 Dwass-Steel-Critchlow-Fligner 检验来分析真实度。采用一般线性模型程序分析精确度（α=.05）：结果：上下颌骨的真实度（P=.003）和精确度（PConclusions）均显著提高：测试的 IOS 获得了相似的 MIP 精确度；但是，用于衔接或纠正咬合碰撞的程序影响了 MIP 关系的精确度。

Accuracy of an artificial intelligence-based program for locating the maxillomandibular relationship of scans acquired by using intraoral scanners

Statement of problem

An artificial-intelligence (AI) based program can be used to articulate scans in maximum intercuspal position (MIP) or correct occlusal collisions of articulated scans at MIP; however, the accuracy of the AI program determining the MIP relationship is unknown.

Purpose

The purpose of the present clinical study was to assess the influence of intraoral scanner (IOS) (TRIOS 5 or i700) and program (IOS or AI-based program) on the accuracy of the MIP relationship.

Material and methods

Casts of a participant mounted on an articulator were digitized (T710). A maxillary and a mandibular scan of the participant were recorded by using 2 IOSs: TRIOS 5 and i700. The scans were duplicated 15 times. Then, each duplicated pair of scans was articulated in MIP using a bilateral occlusal record. Articulated scans were duplicated and allocated into 2 groups based on the automatic occlusal collisions’ correction completed by using the corresponding IOS program: IOS-corrected and IOS-noncorrected group. Three subgroups were created based on the AI-based program (Bite Finder) method: AI-articulated, AI-IOS-corrected, and AI-IOS-noncorrected (n=15). In the AI-articulated subgroup, the nonarticulated scans were imported and articulated. In the AI-IOS-corrected subgroup, the articulated scans obtained in the IOS-corrected group were imported, and the occlusal collisions were corrected. In the AI-IOS-corrected subgroup, the articulated scans obtained in the IOS-noncorrected subgroup were imported, and the occlusal collisions were corrected. A total of 36 interlandmark measurements were calculated on each articulated scan (Geomagic Wrap). The distances computed on the reference scan were used as a reference to calculate the discrepancies with each experimental scan. Nonparametric 2-way ANOVA and pairwise multiple comparison Dwass-Steel-Critchlow-Fligner tests were used to analyze trueness. The general linear model procedure was used to analyze precision (α=.05).

Results

Significant maxillomandibular trueness (P=.003) and precision (P<.001) differences were found among the subgroups. The IOS-corrected and IOS-noncorrected (P<.001) and AI-articulated and IOS-noncorrected subgroups (P=.011) were significantly different from each other. The IOS-corrected and AI-articulated subgroups obtained significantly better maxillomandibular trueness and precision than the IOS-noncorrected subgroups.

Conclusions

The IOSs tested obtained similar MIP accuracy; however, the program used to articulate or correct occlusal collusions impacted the accuracy of the MIP relationship.
