Effects of battery levels and transmission distances on the accuracy and scan time of wireless intraoral scanners in complete-arch scans: An in vitro study.
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.
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.
