The purpose of this study was to assess the accuracy and reliability of tooth width measurements and Bolton Indices delivered by the Clin-Check Pro 6.0 software (Align Technology, San José, CA, USA). Fifty-four plaster casts were selected and measured with a manual calliper by a trained and calibrated observer. The data gathered were compared with those delivered by the software on the corresponding fifty-four virtual casts. The method reliability of the software was assessed by comparing the measurements performed by the software on 201 pairs of clin-checks corresponding to two consecutive treatment phases. Accuracy and reliability were statistically assessed using a mixed model. The software tends to provide larger widths compared with the manual method. Statistically significant differences were found in 23 teeth. At a global level, the mean difference between the methods was -0.19 mm, with a Dahlberg error of 0.24 mm and an intraclass correlation coefficient of 0.98. The Bolton Indices delivered by the two methods had a moderate correlation (ICC = 0.59; 0.69). The within method reliability of the software was extremely high. Tooth width measurements delivered by the software, despite the positive bias, can be considered accurate and clinically acceptable for all teeth except molars. The Bolton Indices made available by the software are not accurate and clinically acceptable, especially in the case of mandibular excess.
本研究旨在评估 Clin-Check Pro 6.0 软件（Align Technology，加利福尼亚州圣何塞）提供的牙齿宽度测量值和 Bolton 指数的准确性和可靠性。选择 54 个石膏模型，由经过培训和校准的观察者使用手动卡尺进行测量。将收集的数据与相应的 54 个虚拟模型上的软件提供的数据进行比较。通过比较对应于两个连续治疗阶段的 201 对 Clin-Check，评估软件的方法可靠性。使用混合模型对准确性和可靠性进行统计评估。与手动方法相比，软件提供的宽度往往更大。在 23 颗牙齿中发现了统计学上的显著差异。在整体水平上，两种方法之间的平均差异为-0.19 毫米，Dahlberg 误差为 0.24 毫米，组内相关系数为 0.98。两种方法提供的 Bolton 指数具有中度相关性（ICC=0.59；0.69）。该软件的方法内可靠性极高。尽管存在正偏差，但软件提供的牙齿宽度测量值可被认为是准确的，并且在除磨牙外的所有牙齿中都具有临床可接受性。该软件提供的 Bolton 指数不够准确，也不具有临床可接受性，尤其是在下颌骨过剩的情况下。
