Abstract

Objective: This pilot study aims to evaluate the clinical accuracy of Smart stereolithography (STL) files generated by the Dental Monitoring® (DM) system by comparing them with gold standard intraoral scans (IOSs).

Methods: Seven aligner patients using the DM application were included. For each patient, Smart STL files generated from remote scans were superimposed onto IOSs using the best-fit algorithm in OnyxCeph software. Differences regarding inclination, angulation, rotation, buccal/lingual, mesial/distal, and intrusion/extrusion were quantified and statistically compared.

Results: Statistically significant differences were observed in inclination, mesial/distal, and buccal/lingual movements, particularly in the posterior segments. However, all deviations remained within clinically acceptable thresholds for single aligner tooth movement.

Conclusions: Despite minor deviations, Smart STL files generated by DM demonstrated sufficient accuracy for use in aligner planning and refinement. These findings highlight the potential of DM-generated Smart STL files for subsequent aligner treatment.

牙科监测®生成的智能立体光刻模型的准确性评估：一项试点研究。

目的：本初步研究旨在通过将牙科监测（DM）系统生成的智能立体光刻（STL）文件与金标准口内扫描（ios）进行比较，评估其临床准确性。方法：纳入7例使用DM应用的对准器患者。对于每位患者，使用OnyxCeph软件中的最佳拟合算法将远程扫描生成的Smart STL文件叠加到ios上。对倾斜、成角、旋转、颊/舌、中/远端、侵入/挤压等方面的差异进行量化和统计比较。结果：在倾斜、中/远端和颊/舌运动方面观察到统计学上的显著差异，特别是在后节段。然而，所有的偏差仍然在临床可接受的阈值范围内。结论：尽管存在较小的偏差，DM生成的Smart STL文件在对准器规划和改进中具有足够的准确性。这些发现突出了dm生成的Smart STL文件在后续矫直器治疗中的潜力。

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.
