摘要

目的:本研究的目的是比较使用两种不同软件程序对使用两种类型的石膏模型扫描仪(激光扫描仪和计算机断层扫描[CT]扫描仪)生成的数字模型进行测量的准确性和可靠性。方法:采用3Shape激光扫描仪和Flash CT扫描仪对30个石膏模型进行扫描。两名审查员使用数字卡尺对石膏模型进行测量,并使用Ortho Analyzer (3Shape)和Digimodel®(OrthoProof)软件程序对数字模型进行测量。获得了42项测量结果,包括牙齿直径、冠高度、覆盖、覆盖咬合、犬齿间和磨牙间距离以及矢状关系。结果:石膏与数字模型测量结果无统计学差异(方差分析);然而,一些差异具有临床相关性。在Bland-Altman分析中,使用两种扫描方法进行的石膏和数字模型测量显示出高的类内系数相关值和可接受的95%的一致性限。所使用的软件不影响测量的准确性。结论:采用激光和CT扫描对石膏模型进行数字化建模,采用两种不同的软件程序进行测量,结果准确可靠。因此,制造方法和软件都可以互换使用。

Accuracy and reliability of measurements performed using two different software programs on digital models generated using laser and computed tomography plaster model scanners.

Accuracy and reliability of measurements performed using two different software programs on digital models generated using laser and computed tomography plaster model scanners.

Accuracy and reliability of measurements performed using two different software programs on digital models generated using laser and computed tomography plaster model scanners.

Accuracy and reliability of measurements performed using two different software programs on digital models generated using laser and computed tomography plaster model scanners.

Objective: The aim of this study was to compare the accuracy and reliability of measurements performed using two different software programs on digital models generated using two types of plaster model scanners (a laser scanner and a computed tomography [CT] scanner).

Methods: Thirty plaster models were scanned with a 3Shape laser scanner and with a Flash CT scanner. Two examiners performed measurements on plaster models by using digital calipers and on digital models by using Ortho Analyzer (3Shape) and Digimodel® (OrthoProof) software programs. Forty-two measurements, including tooth diameter, crown height, overjet, overbite, intercanine and intermolar distances, and sagittal relationship, were obtained.

Results: Statistically significant differences were not found between the plaster and digital model measurements (ANOVA); however, some discrepancies were clinically relevant. Plaster and digital model measurements made using the two scanning methods showed high intraclass coefficient correlation values and acceptable 95% limits of agreement in the Bland-Altman analysis. The software used did not influence the accuracy of measurements.

Conclusions: Digital models generated from plaster casts by using laser and CT scanning and measured using two different software programs are accurate, and the measurements are reliable. Therefore, both fabrication methods and software could be used interchangeably.

期刊介绍: The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches. The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
