Abstract

Purpose: The purpose of the study was to investigate the accuracy of complete-arch intraoral scans for all-on-4 implant treatment under simulated intraoral variables.

Materials and methods: A maxillary model designed to receive 4 implants in the regions of first molars and canines was used. Intraoral digital scans were completed in a simulation device by simulating two2 different clinical conditions: normal intraoral variables (NIV) and limited intraoral variables (LIV). Digital scans were obtained using five 5 different IOSs: Trios 3 (TRI), Primescan (PR), iTero 2 (ITE), Medit i500 (MDT), and Aadva IOS 100P (AAD). Ten scans of each IOS were made and exported as STL files. Assessment of precision and trueness was conducted with Geomagic 3D analysis software. Each STL file was individually aligned with the reference scan and 3D differences were calculated using the root mean square (RMS) value. Data was statistically analyzed using 2-way ANOVA and Tukey HSD tests (α=.05).

Results: Regarding trueness, 2-way ANOVA and Tukey comparison tests revealed significant differences between different IOSs and intraoral variables. The AAD under LIV presented significantly higher RMS than TRI, PR, ITE, and MDT (p<.001). Regarding precision, the lowest mean RMS was obtained in the IOS group of PR under NIV. AAD presented significantly higher mean RMS in the groups of both NIV and LIV (p<.001). Limited intraoral variables significantly increased the RMS values for all IOSs tested (TRI, PR, ITE, MDT, and AAD).

Clinical significance: Accuracy of complete arch all-on-4 implant scans were affected by different IOSs and intraoral variables. Simulating intraoral variables while testing IOSs might help to better validate their clinical use.

模拟口腔内变量下全弓、全on-4种植体扫描的准确性。

目的：本研究的目的是在模拟口腔内变量的情况下，研究全弓口腔内扫描对全on-4种植体治疗的准确性。材料和方法：采用上颌模型，在第一磨牙和犬齿区域植入4颗种植体。通过模拟正常口内变量（NIV）和受限口内变量（LIV）两种不同的临床情况，在模拟装置中完成口内数字扫描。使用5种不同的IOS进行数字扫描：Trios 3 （TRI）、Primescan （PR）、iTero 2 （ITE）、Medit i500 （MDT）和Aadva IOS 100P （AAD）。对每个IOS进行10次扫描并导出为STL文件。利用Geomagic三维分析软件进行精度和真实度评估。每个STL文件单独与参考扫描对齐，并使用均方根（RMS）值计算3D差异。采用2-way ANOVA和Tukey HSD检验对数据进行统计学分析（α= 0.05）。结果：关于真实性，2-way ANOVA和Tukey比较检验显示不同的iss和口腔内变量之间存在显著差异。与TRI、PR、ITE和MDT相比，LIV下的AAD的RMS值明显更高(p)。临床意义：全弓all-on-4种植体扫描的准确性受到不同的ios和口腔内变量的影响。在测试iss时模拟口腔内变量可能有助于更好地验证其临床应用。

期刊介绍： This journal explores the myriad innovations in the emerging field of computerized dentistry and how to integrate them into clinical practice. The bulk of the journal is devoted to the science of computer-assisted dentistry, with research articles and clinical reports on all aspects of computer-based diagnostic and therapeutic applications, with special emphasis placed on CAD/CAM and image-processing systems. Articles also address the use of computer-based communication to support patient care, assess the quality of care, and enhance clinical decision making. The journal is presented in a bilingual format, with each issue offering three types of articles: science-based, application-based, and national society reports.
