“…Twenty-four studies included reference models as controls in their methodology design [ 6 , 7 , 34 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 55 , 56 , 57 ]. The controls included were a dental stone cast ( n = 8), a digital STL image of a dental stone cast ( n = 3), typodont digital STL image ( n = 7), typodont ( n = 1), prefabricated resin model digital STL image ( n = 2), patient intraoral scan image (2) or a dry human skull ( n = 1).…”

“…The majority of studies investigated SLA ( n = 20), MJ ( n = 11), DLP ( n = 9) and, to a lesser extent, FFF ( n = 6), BJ ( n = 2) and CLIP ( n = 1). With regards to printing parameters, one study reported following the manufacturers’ recommendations [ 6 ], while others explicitly detailed the printing parameters used [ 4 , 19 , 36 , 37 , 38 , 42 , 43 , 45 , 46 , 47 , 49 , 50 , 51 , 52 , 55 , 56 , 57 ]. In contrast, the remainder of the studies did not provide clear details regarding the printing parameters used.…”

“…This includes the data acquisition and image processing of the oral hard and soft tissues, and the myriad of parameters involved in the manufacturing and postprocessing processes [ 5 ]. Moreover, models acquired through vat polymerisation and material jetting are prone to shrinkage during the polymerisation stage as well as having stair-step surfaces due to the layering technique used in construction [ 6 ]. In addition, a recent study demonstrated that models exhibit dimensional changes postprocessing as they age with their dimensions reported to be significantly different after three-weeks of manufacturing [ 7 ].…”

The use of additive manufacturing in dentistry has exponentially increased with dental model construction being the most common use of the technology. Henceforth, identifying the accuracy of additively manufactured dental models is critical. The objective of this study was to systematically review the literature and evaluate the accuracy of full-arch dental models manufactured using different 3D printing technologies. Seven databases were searched, and 2209 articles initially identified of which twenty-eight studies fulfilling the inclusion criteria were analysed. A meta-analysis was not possible due to unclear reporting and heterogeneity of studies. Stereolithography (SLA) was the most investigated technology, followed by digital light processing (DLP). Accuracy of 3D printed models varied widely between <100 to >500 μm with the majority of models deemed of clinically acceptable accuracy. The smallest (3.3 μm) and largest (579 μm) mean errors were produced by SLA printers. For DLP, majority of investigated printers (n = 6/8) produced models with <100 μm accuracy. Manufacturing parameters, including layer thickness, base design, postprocessing and storage, significantly influenced the model’s accuracy. Majority of studies supported the use of 3D printed dental models. Nonetheless, models deemed clinically acceptable for orthodontic purposes may not necessarily be acceptable for the prosthodontic workflow or applications requiring high accuracy.

“…The advantage of this technology is that the 3D objects grow continuously without interruption by controlling the oxygen flux. Jin et al studied the accuracy of dental replica models produced by SLA and PolyJet techniques compared with the conventional method. They measured the trueness and the precision of printed models with conventional stone models.…”

Purpose To evaluate the accuracy of three‐dimensional (3D) printed models manufactured using two different printer technologies with different model base designs. Materials and Methods A maxillary typodont was scanned using a desktop scanner to generate the Standard Tessellation Language (STL) file as a reference scan. After the scanning procedure, the STL file was exported to Model Builder™ for designing the following two types of the model bases: a solid base design and a hollow base design with a 2.0 mm thickness of the external shell. Each design was printed to produce 10 models using a Continuous Liquid Interface Production (CLIP) printer and a Digital Light Processing (DLP) printer. The following four groups were tested: CLIP with solid base (CS); CLIP with hollow base (CH); DLP with solid base (DS); and DLP with hollow base (DH). A total of 40 models were scanned using the same desktop scanner to generate the STL files for evaluation of the accuracy by evaluation of trueness and precision. All STL files were superimposed with the control STL file via surface matching software and a comparison was performed using the 3D color mapping function and a 2D comparison of 48 points selected on the tested model. The data were collected by measuring the deviation between the tested model and the reference scan. Trueness was calculated by using the comparison among four tested groups. The Kruskal‐Wallis analysis was conducted to assess the overall statistical significance of differences among the tested groups (α = 0.05). For precision measurement, the evaluation was conducted using Intraclass Correlation Coefficient (ICC) value at 95% confident interval to determine the deviation within the same tested groups. Results The median values for the deviated distance of the four tested groups were 0.045 (CH), 0.035 (CS), 0.077 (DH), and 0.077 mm (DS). There were no statistically significant differences between the trueness of the two groups when using the same printers regardless of the designs of model base (p > 0.05). However, when comparing the two printers using the same model base design and the two different designs of model base, there were statistically significant differences in trueness (p < 0.05). The 3D printed models created using CLIP technology had higher trueness than the DLP technology printer. Precision of the 3D printed model was displayed in ICC value. The ICC values of four tested groups were 0.968 (CH), 0.981 (CS), 0.969 (DH), and 0.983 (DS). All tested groups were classified as exhibiting an excellent level of precision based on 95% confident interval of the ICC estimation. Conclusions The accuracy of 3D printed models was affected by the printer technology regardless of whether the model base was solid or hollow. The CLIP technology printer produced significantly less variation from the reference model than the DLP printer. However, all of the 3D printed models were determined to exhibit a clinically acceptable level of accuracy based on the recorded dimensions being less than 100 µm diffe...

Aim. To study the dimensional accuracy of dentition models produced by digital and conventional methods using an experimental model and digital technologies.Materials and methods. This article presents an assessment of the dimensional accuracy of jaw models created using an Asiga Max UV 3D printer from digital images of dentition created by an iTero Cadent intraoral scanner and plaster jaw models obtained from one-stage two-layer A-silicone impressions. The DentalCAD software and the Meshlab computer program were used to study the dimensional accuracy of the as-obtained digital images. The nonparametric Wilcoxon rank test was used for statistical analysis of the obtained data.Results. It is established that jaw models made of DETAX Freeprint model UV photopolymer using an Asiga Max UV 3D printer, based on digital impressions obtained by an iTero Cadent intraoral scanner, have a greater dimensional accuracy in comparison with plaster jaw models obtained from single-stage double-layer A-silicone impressions by 31.6% with a signifi cance level p < 0.05.Conclusion. Jaw models created using an Asiga Max UV 3D printer are characterized by high dimensional accuracy as compared to plaster models.
