A Comparative Analysis of Dental Measurements in Physical and Digital Orthodontic Case Study Models

Abstract

Background and Objectives: Study models are essential tools used in the dental teaching process. The aim of the present study was to compare the values obtained by manual and digital orthodontic measurements on physical and digital case study models. Materials and Methods: The physical experimental models were obtained by traditional pouring (improved stone-type IV gypsum products) and by additive manufacturing (resins). The digital experimental models were created by scanning the physical ones, using a white light-emitting diode (LED) source and an L-shaped dental scanner—Swing DOF (DOF, Seoul, Korea). The physical study models were first measured using a digital caliper, and then, they were scanned and evaluated using the DentalCad 3.0 Galway software (exocad GmbH, Darmstadt, Germany). The Pont, Linder–Harth, and Bolton indices, which are used in orthodontics for training students, were derived using the available data. Results: When comparing the linear measurement mean ranks taken on physical study models to those of digital models, no statistically significant differences (p > 0.05) were found. A similar result was also shown when the dentoalveolar growth indicators were analyzed. Conclusions: It can be concluded that dental study models made by direct light processing (DLP) and pouring type IV class gypsum are both acceptable for orthodontic teaching purposes.

Treatment of maxillary transverse deficiency with rapid expansion of the palate with mini-implant: a review

“…They allow for static and dynamic analysis of the arches, constituting a very important tool for planning. 9 The study is carried out in the three planes of space: transverse, anteroposterior or sagittal and vertical, each one of them considering each arch independently and the relationship between them is studied with the models mounted on an articulator in centric relation (a) transverse analysis, the reference plane used to determine transverse deviations (unilateral or bilateral compression of the arches, symmetry, lateral crossbites) is the median sagittal plane; (b) anteroposterior or sagittal analysis, the analysis of sagittal problems (overjet, canine and molar relationship, and dental positions in the mesiodistal direction of the lateral sectors) takes the transversal plane as the reference plane; and (c) vertical analysis, for the study of dental positions in a vertical sense (overbite or overbite, under or supra eruption of one or a group of teeth), the occlusal plane is used, which is considered as the horizontal plane.…”

Biopolymers and Their Application in Bioprinting Processes for Dental Tissue Engineering

“…DLP fabrication methods are regularly used to convert 3D models into 3D structures for dental implants ( Figure 2 c). Furthermore, DLP can polymerize each layer of resin much more rapidly compared to SLA, which is a preferable process [ 46 ].…”

Dentistry: A Multidisciplinary Approach

“…It underscores the unique dental care requirements of EB patients and suggests the need for specialized treatment approaches [ 19 ]. The article “A Comparative Analysis of Dental Measurements in Physical and Digital Orthodontic Case Study Models” by Elena-Raluca Baciu et al [ 20 ] compares manual and digital orthodontic measurements on both physical and digital models. The study aims to determine the reliability of digital models in orthodontic analyses, focusing on the reproducibility of dental arch characteristics.…”

“…It involves a detailed comparison of different measurement techniques applied to various types of models, including physical models created through traditional pouring and additive manufacturing as well as digital models obtained through scanning. The research concludes that both traditional and digital models are effective for orthodontic teaching, with no significant differences in the measurement results [ 20 ]. The article “The Impact of Simulated Bruxism Forces and Surface Aging Treatments on Two Dental Nano-Biocomposites—A Radiographic and Tomographic Analysis” by Amelia Anita Boitor et al [ 21 ] investigates the effects of simulated bruxism forces and aging treatments on two dental nano-biocomposites.…”
