Impact of scanning interruptions on accuracy of implant-supported full-arch scans: An in-vitro pilot study
Purpose
To assess the impact of involuntary interruptions (simulating tracking loss by moving the scanner out of its focal distance) and voluntary interruptions (pressing the scanner's turn-on button) on the accuracy of implant-supported full-arch scans using an intraoral scanner (TRIOS 5, version 22.1.10; 3Shape; Copenhagen, Denmark).
Materials and Methods
An edentulous model with four implants was digitized with an industrial scanner (Artec Micro II; Artec 3D) to create a reference scan. Four groups (n = 30) were established based on the number of interruptions during scanning: Zero Group (no interruptions; control group), 6-V Group (six voluntary interruptions), 6-I Group (six involuntary interruptions), and 12-I Group (twelve involuntary interruptions). Primary outcome was accuracy assessed by the Root Mean Square (RMS) method. Secondary outcomes included scanning time and the number of photograms. Data were analyzed using one-way ANOVA and post hoc Tukey multiple comparison tests (α=0.05).
Results
A total of 120 digital scans were conducted. The Zero group achieved a RMS error of 291 ± 47 µm, a scanning time of 68 ± 6s, and 1320 ± 129 photograms. 6-V group significantly reduced RMS error (MD -102 µm [IC 95 %: -141, -63]), decreased scanning time (MD -20s [IC 95 %: -25, -17]), and reduced photograms (MD -415 photograms [IC 95 %: -506, -324]) compared to the control group (P<.001). Simulations of 6 or 12 involuntary interruptions did not affect accuracy compared to the control group (P>.05).
Conclusions
Voluntary interruptions during scanning, achieved by pressing the scanner's turn-on button, appear to enhance accuracy due to image preprocessing, while involuntary interruptions had no significant impact on the accuracy of implant-supported full-arch scans.
Clinical Significance
Voluntary stop during scanning implant-supported full-arches may result in better-fitting prostheses owing to higher scan accuracy and efficiency.
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.
