“…Moreover, testing inexperienced operators in different impression methods could also enhance the scope of the study. For example, although Ko et al compared the time spent making the plans on the impression methods instead of impression‐taking time, they enhanced the scope of their study using different operators (16 orthodontist). The second limitation was that, in our study, a single intraoral scanner was used to take impressions and a single conventional impression was hand‐mixed.…”

Background The comfortness and effectiveness of digital and conventional impression methods in children have not yet been compared. Aim To assess the digital and conventional impression methods in children in terms of comfort, preference, and the time required to take impressions. Design Digital impressions were taken by using an intraoral scanner, and conventional impressions were taken by using alginate from 28 patients by the same operator. In each impression‐taking‐process, comfort was assessed by both the children and the clinician, and the chairside times were written. Student's t tests and Mann‐Whitney U tests were used for statistical analyses, and P < .05 was considered to be significant. Results The digital impression was considered to be more comfortable in the assessments by both the children and the clinician (P < .001). The total time the digital impression took was 465.89 ± 76.71 second(s) while that of the conventional impression was 450.25 ± 64.08 s when the chairside times of the two impression methods were compared. There was no statistically significant difference (P = .41). Conclusion The digital impression method compared with the conventional impression method was found to be both more comfortable and preferable by the children, but there was no difference in terms of the time required to take impressions.

“…Besides these controversial statements, Ko et al [15] and Yilmaz et al [12] showed in their studies that both models could be used without any negative implication for orthodontic treatments. These differences in measurements between different types of models can be linked to features such as malocclusions prior to treatment Verma et al [23], type of impression material [26] and type of printing technique [27,28], and that they may present statistically significant differences yet not clinically relevant to justify the contraindication of digital models [23,[26][27][28].…”

“…This technology can generate digital study models by scanning the alginate impression or by direct intraoral scanning [2]. Much has been discussed about the accuracy and reproducibility of this technique, but studies report them as satisfactory so as not to interfere with the success of orthodontic planning, and the use of these models have become a reality in clinical practice [14,15].…”

Context: Digital study models have become a safe and advantageous alternative for diagnosis and planning in dentistry. Despite the superior characteristics in comparison with traditional plaster models, professionals seem to resist the use of new technologies. Aims: To assess the level of knowledge and the use of digital models through a questionnaire applied to dental professionals. Methods: A questionnaire with 12 multiple-choice questions about plaster models, digital, and use of the 3Shape - 3D viewer software was answered by 76 orthodontists (42 women and 34 men; mean age =37.82 years (SD ± 7.60)) and 30 general dental surgeons (18 women and 12 men; mean age of 33.93 years (SD ± 8.45)) in Aracaju, Sergipe, Brazil. Data were tabulated in Excel spreadsheets and then analyzed using the SPSS statistical software version 20. An absolute analysis of frequency and percentage of responses was performed. Results: Most professionals reported using plaster models and claimed their low cost as justification for their use (P = 0.001). Aware of the benefits of digital models, professionals of both classes highlighted the facilitated storage and search for information as the main advantages, the cost and infrastructure as the main disadvantages. Regarding the use of the 3Shape - 3D viewer software, orthodontists showed better utilization of this resource than general dental surgeons (P = 0.0198). Conclusion: It verified that most professionals make use of plaster models. However, despite knowing the advantages of digital models, their cost is sees as a limiting factor for adherence to this technology.

“…The advantage of digital study models is that they are not prone to damage, fracture, or loss. Not only is no extra space needed to store the models, digital models also make setting up models and sending models for referral easy [8][9][10] .…”

Background: Due to advances in digital technology, it is possible to obtain digital dental models through intraoral scanning. The stereolithographic data collected from the scanner can subsequently be printed into a three-dimensional dental model in resinic material. However, the accuracy between digital dental models and printed dental models needs to be evaluated since it might affect diagnosis and treatment planning in orthodontic treatment. This study aimed to evaluate the accuracy of digital models scanned by a Trios intraoral scanner and three-dimensional dental models printed using a Formlabs 2 3D printer in linear measurements and Bolton analysis. Methods: A total of 35 subjects were included in this study. All subjects were scanned using a Trios intraoral scanner to obtain digital study models. Stereolithographic data from previous scanning was printed using a Formlabs 2 3D printer to obtain printed study models. Mesiodistal, intercanine, intermolar, and Bolton analysis from all types of study models were measured. The intraclass correlation coefficient was used to assess intraobserver and interobserver reliability. All data were then statistically analyzed. Results: The reliability tests were high for both intraobserver and interobserver reliability, which demonstrates high reproducibility for all measurements on all model types. Most of the data compared between study models showed no statistically significant differences, though some data differed significantly. However, the differences are considered clinically insignificant. Conclusion: Digital dental models and three-dimensional printed dental models may be used interchangeably with plaster dental models for diagnostic and treatment planning purposes. Keywords: Accuracy, 3D printing, digital dental model, printed dental model.
