Abstract

Objectives: To investigate whether the predicted changes in overbite (OB) and overjet (OJ) in Align Technology's (Santa Jose, Calif) digital treatment plan for the prescribed course of treatment with the Invisalign appliance were consistent with those same changes in OB and OJ measured with the Geomagic Control X (Geomagic US, Research, Triangle Park, NC) metrology software system.

Materials and methods: Geomagic Control X software was used to determine OB and OJ differences between the pretreatment and predicted outcome. STL files for patients satisfying inclusion criteria and undergoing nonextraction orthodontic treatment with the Invisalign appliance. The differences were compared, using the Bland-Altman analysis, to the corresponding data provided by Align Technology's digital treatment-planning interface, ClinCheck.

Results: Data regarding 76 adult patients who satisfied strict inclusion criteria were assessed. The Shapiro-Wilks test indicated normality (P > .05). The Bland-Altman analysis showed high levels of agreement between the two measurements, with a bias range of -0.131 to 0.111 for OB and -0.393 to 0.03 for OJ recorded.

Conclusions: Clinicians and researchers can be confident that measurement data provided by Invisalign's ClinCheck digital treatment-planning facility concerning OB and OJ changes from the initial to the predicted treatment outcome are valid.

使用隐适美矫正器预测咬合过度和咬合过紧的变化：一项验证研究。

目的研究 Align 技术公司（加利福尼亚州圣何塞）的数字化治疗计划中对隐适美矫正器规定疗程的咬合过度（OB）和咬合过高（OJ）的预测变化是否与 Geomagic Control X（Geomagic US，Research，Triangle Park，NC）计量软件系统测量的咬合过度和咬合过高的变化一致：使用 Geomagic Control X 软件确定治疗前与预测结果之间的 OB 和 OJ 差异。对符合纳入标准并使用隐适美（Invisalign）矫治器进行非拔牙正畸治疗的患者的 STL 文件进行分析。使用 Bland-Altman 分析法将差异与 Align Technology 的数字治疗规划界面 ClinCheck 提供的相应数据进行比较：对符合严格纳入标准的 76 名成年患者的数据进行了评估。Shapiro-Wilks 检验表明数据呈正态性（P > .05）。Bland-Altman分析表明，两种测量结果的一致性很高，OB的偏差范围为-0.131至0.111，OJ的偏差范围为-0.393至0.03：临床医生和研究人员可以确信，隐适美 ClinCheck 数字化治疗规划设备提供的有关从初始治疗结果到预测治疗结果的 OB 和 OJ 变化的测量数据是有效的。
