Comparison of trueness, time, and number of images among different denture digitization protocols.
Purpose: To compare trueness, time, and number of images of different denture digitization protocols.
Materials and methods: Maxillary and mandibular complete prostheses (n = 10) were fabricated and attached with four fiducial markers. Reference scans were obtained using a laboratory scanner. Test scans were obtained using three different protocols: intraoral scanner (IOS) with manufacturer's scanning pattern (MA), IOS with rolling scanning pattern (RO), and IOS- polyvinylsiloxane technique (IOS-PVS). The scan time and number of images taken were recorded for analysis. Using 3-dimensional (3D) inspection software (Geomagic control X), corresponding test scans were superimposed to the reference scan using overall best fit. For trueness analysis, the root mean square (RMS) value of the overall best-fit superimposition was calculated. One-way ANOVA followed by Games-Howell and Tukey post-hoc tests were applied to analyze trueness, scan time, and number of images. Qualitative analysis of trueness was performed using 3D color mapping.
Results: The lowest RMS value was in the mandibular RO protocol (0.10 ±0.01 mm). The highest RMS value was mandibular scans of the IOS-PVS protocol (1.46 ± 0.09 mm). The longest digitization time was recorded in the maxillary MA group (3.34 ± 0.70 min), while the shortest was in the mandibular RO protocol (2.48 ± 0.56 min). Qualitative analysis revealed that deviation in IOS-PVS protocol occurred around the border area of the prosthesis.
Conclusion: The denture digitization protocols tested significantly affected trueness, total scanning time, and number of images. Digitizing dentures using the RO protocol improved trueness and reduced scanning time and the number of images.
期刊介绍：
The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. The journal publishes evidence-based original scientific articles presenting information that is relevant and useful to prosthodontists. Additionally, it publishes reports of innovative techniques, new instructional methodologies, and instructive clinical reports with an interdisciplinary flair. The journal is particularly focused on promoting the study and use of cutting-edge technology and positioning prosthodontists as the early-adopters of new technology in the dental community.
