“…Previous studies have also reported that PMMA resin has a rougher surface than 3D printed resin. 23 24 Furthermore, all the tested groups in this study showed increased surface roughness after masticatory simulation compared to the baseline. For both digitally and conventionally fabricated interim restorative materials, material wear leads to a rougher surface and promotes more plaque accumulation on the worn surfaces.…”

PURPOSE The purpose of this in vitro study was to investigate the wear resistance and surface roughness of three interim resin materials, which were subjected to chewing simulation. MATERIALS AND METHODS Three interim resin materials were evaluated: (1) three-dimensional (3D) printed (digital light processing type), (2) computer-aided design and computer-aided manufacturing (CAD/CAM) milled, and (3) conventional polymethyl methacrylate interim resin materials. A total of 48 substrate specimens were prepared. The specimens were divided into two subgroups and subjected to 30,000 or 60,000 cycles of chewing simulation (n = 8). The wear volume loss and surface roughness of the materials were compared. Statistical analysis was performed using one-way analysis of variance and Tukey's post-hoc test (α=.05). RESULTS The mean ± standard deviation values of wear volume loss (in mm 3 ) against the metal abrader after 60,000 cycles were 0.10 ± 0.01 for the 3D printed resin, 0.21 ± 0.02 for the milled resin, and 0.44 ± 0.01 for the conventional resin. Statistically significant differences among volume losses were found in the order of 3D printed, milled, and conventional interim materials ( P <.001). After 60,000 cycles of simulated chewing, the mean surface roughness (Ra; μm) values for 3D printed, milled, and conventional materials were 0.59 ± 0.06, 1.27 ± 0.49, and 1.64 ± 0.44, respectively. A significant difference was found in the Ra value between 3D printed and conventional materials ( P =.01). CONCLUSION The interim restorative materials for additive and subtractive manufacturing digital technologies exhibited less wear volume loss than the conventional interim resin. The 3D printed interim restorative material showed a smoother surface than the conventional interim material after simulated chewing.

“…This systematic review and meta-analysis is the first of its kind to analyze and document all the available studies comparing the mechanical and/or physical properties of the 3D-printed provisional crown and FPD materials with CAD/CAM milled and/or conventional provisional resins. All twentyfive papers included were in vitro studies [16,[26][27][28][29][30][31][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52]. The overall findings reveal that the mechanical and physical properties of the provisional crown and FDP materials are affected by the technique of fabrication and composition of the tested materials.…”

“…(ii) Comparing the change in color values of hybrid composite-based 3D-printed provisional resins: Studies by Atria et al [42] reported a greater change in color for hybrid composite-based 3D-printed provisional resins when compared to conventional bisacrylic and PMMA resins. On the contrary, Taşın et al [48] and Song et al [44] reported greater change in color for conventional resins. Compared to CAD/CAM milled PMMA resins, a greater change in color was reported in 3D-printed hybrid composite resins [15,19].…”

“…One study [42] showed that hybrid 3D-printed resins have a higher surface roughness when compared to conventional PMMA, conventional bis-acrylic, and CAD/CAM milled PMMA-based resins. However, the results of a study by Taşın et al [48] gave contradictory results, with hybrid 3D-printed resins displaying a lower surface roughness when compared to conventional PMMA, conventional bis-acrylic, and CAD/CAM milled PMMA-based resins. Simoneti et al [53] reported that the surface roughness of SLS 3D-printed resins was higher, and that of SLA-based 3D-printed resins was lower when compared to conventional PMMA and bis-acrylic-based interim resins.…”

“…Thus, the pooled estimate favored 3D-printed PMMA resin with p < 0.0001 (Figure 6). (ii) Comparing the fracture strength of bis-acrylic and other photopolymer hybrid 3Dprinted provisional resins: the FSs of 3D-printed bis-acrylic resin [48], micro-hybrid resin [46], photopolymer resin [52], and UDMA-based resins [50] were reported to be lower than PMMA-based CDA/CAM resins. A study by Henderson et al [51] reported that bis-acrylic-based 3D-printed resins have lower FS when compared to bis-acrylic-based conventional resins.…”

Physical and Mechanical Properties of 3D-Printed Provisional Crowns and Fixed Dental Prosthesis Resins Compared to CAD/CAM Milled and Conventional Provisional Resins: A Systematic Review and Meta-Analysis

et al. 2022

Newly introduced provisional crowns and fixed dental prostheses (FDP) materials should exhibit good physical and mechanical properties necessary to serve the purpose of their fabrication. The aim of this systematic literature review and meta-analysis is to evaluate the articles comparing the physical and mechanical properties of 3D-printed provisional crown and FDP resin materials with CAD/CAM (Computer-Aided Designing/Computer-Aided Manufacturing) milled and conventional provisional resins. Indexed English literature up to April 2022 was systematically searched for articles using the following electronic databases: MEDLINE-PubMed, Web of Science (core collection), Scopus, and the Cochrane library. This systematic review was structured based on the guidelines given by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The focused PICO/PECO (Participant, Intervention/exposure, Comparison, Outcome) question was: ‘Do 3D-printed (P) provisional crowns and FDPs (I) have similar physical and mechanical properties (O) when compared to CAD/CAM milled and other conventionally fabricated ones (C)’. Out of eight hundred and ninety-six titles, which were recognized after a primary search, twenty-five articles were included in the qualitative analysis, and their quality analysis was performed using the modified CONSORT scale. Due to the heterogeneity of the studies, only twelve articles were included for quantitative analysis. Within the limitations of this study, it can be concluded that 3D-printed provisional crown and FDP resin materials have superior mechanical properties but inferior physical properties compared to CAD/CAM milled and other conventionally fabricated ones. Three-dimensionally printed provisional crowns and FDP materials can be used as an alternative to conventional and CAD/CAM milled long-term provisional materials.

PurposeDenture base materials are commonly exposed to different denture cleansers which can affect their essential properties. This study aimed to assess the effect of denture cleansers on color stability and surface roughness of poly methyl methacrylate (PMMA) denture bases fabricated from different techniques: Conventional heat‐polymerizing, CAD/CAM additive and CAD/CAM subtractive.Materials and MethodsIn this in vitro study, 24 disc‐shaped specimens were fabricated by the mentioned methods for each group. The initial color and surface roughness of specimens were recorded. The specimens were randomly divided into three subgroups (n = 8): a control subgroup (distilled water), and two experimental subgroups of bioactive oxygen tablet (Corega) and 1% sodium hypochlorite solution. Then they were immersed in the solutions simulating 180 days of clinical use. Color change (∆E) was measured by a spectrophotometer according to the CIE L*a*b* color space and the American National Bureau of Standards (NBS = 0.92 × ∆E). Final surface roughness was recorded by a profilometer and its change was calculated. The Kruskal–Wallis test followed by the Wilcoxon signed rank test were used for statistical analyses (α = .05).ResultsThe conventional and CAD/CAM subtractive groups showed an increase in surface roughness following immersion in hypochlorite solution (p < .05). After immersion in the solutions, the highest surface roughness was noted in the conventional group, and the lowest in the CAD/CAM additive group. The CAD/CAM additive group experienced a significant color change in hypochlorite solution (p < .05) and showed the highest color change while the CAD/CAM subtractive group showed the lowest color change in all denture cleanser solutions.ConclusionAlthough the CAD/CAM additive denture base resins had the lowest surface roughness after exposure to denture cleanser solutions, they showed significant color change, which should be taken into account. Using hypochlorite as a denture cleanser should be cautioned due to its negative effects on the surface roughness and color stability of denture base materials.
