Abstract

Objectives: This study explored the effects of battery levels and transmission distances on the accuracy and scan time of wireless intraoral scanners (IOSs) during complete-arch scans.

Methods: A maxillary complete-arch typodont was used as a master model. Two wireless IOSs (Trios 4 wireless [TR4] and Trios 5 [TR5]; 3Shape A/S, Denmark) were evaluated across 4 battery levels (1∼25%, 26∼50%, 51∼75%, and 76∼100%) and 3 transmission distances (0.8±0.5 m, 2.0±0.5 m, and 4.0±0.5 m). A reference standard tessellation language (STL) file was generated by digitizing the master model with a laboratory scanner (InEos X5; Dentsply Sirona, USA). A total of 480 experimental STL files (n=20) were generated, and the corresponding scan time were recorded. Scanning accuracy (trueness and precision) was assessed by calculating the root mean square (RMS) deviation via Geomagic Control X. Two-way ANOVA was performed to analyze the data (α=0.05).

Results: Battery level and transmission distance significantly affected the trueness and scan time (p<0.05). The least distortion was observed at low battery levels (1∼25%) and the most distant ranges (4.0±0.5 m) (TR4: 71.64±16.16 µm and TR5: 57.94±10.96 µm), whereas the fastest scans occurred at high battery levels (76∼100%) and close distances (0.8±0.5 m) (TR4: 54.20±4.51 s and TR5: 48.65±4.45 s). The scanning precision was independently influenced by both factors (p<0.05), with the highest precision at high battery levels (76∼100%) and close distances (0.8±0.5 m) (TR4: 54.92±5.24 µm and TR5: 63.88±12.86 µm).

Conclusions: Moderate transmission distances (2.0±0.5 m) did not impair scanning trueness, even at lower battery levels (1∼25%). However, maintaining battery levels above 50% is recommended for optimal scanning accuracy and efficiency.

Clinical significance: This study highlights the importance of optimizing transmission distances and battery levels to increase the performance of wireless IOSs in complete-arch scanning workflows.

电池电量和传输距离对全弓扫描中无线口内扫描仪准确性和扫描时间的影响：一项体外研究。

目的：本研究探讨电池电量和传输距离对无线口内扫描仪（IOSs）全弓扫描准确度和扫描时间的影响。方法：以上颌全弓型牙型为主要模型。两个无线ios (Trios 4无线[TR4]和Trios 5 [TR5]；3 shape A/S，丹麦)在4个电池级别（1 ~ 25%、26 ~ 50%、51 ~ 75%和76 ~ 100%）和3个传输距离（0.8±0.5 m、2.0±0.5 m和4.0±0.5 m）上进行评估。参考标准镶嵌语言（STL）文件是通过实验室扫描仪(InEos X5；Dentsply Sirona， USA)。共生成480个实验STL文件（n=20），记录相应的扫描时间。通过Geomagic Control x软件计算均方根（RMS）偏差评估扫描精度（正确率和精密度）。采用双因素方差分析（Two-way ANOVA）对数据进行分析（α=0.05）。结果：电池电量和传输距离显著影响扫描正确率和扫描时间(p结论：中等传输距离（2.0±0.5 m）不影响扫描正确率，即使在较低的电池电量（1 ~ 25%）。但是，为了获得最佳的扫描精度和效率，建议将电池电量保持在50%以上。临床意义：本研究强调了优化传输距离和电池电量对提高全弓扫描工作流程中无线ios性能的重要性。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
