Purpose: To evaluate the color stability of 3D-printed interim restorations with different surface treatments while immersed in various staining solutions or beverages (artificial saliva, tea, coffee, and wine) for 6 months. Material and Methods: An acrylic tooth was prepared for an all-ceramic fullcoverage restoration. A laboratory scanner was used to digitize the prepared abutment tooth. A virtual all-ceramic full-coverage restoration was designed on the digitized abutment tooth using a laboratory CAD/CAM software. Eighty abutment teeth and interim restorations were 3D-printed with tooth-colored photopolymerizing resin. The restorations were randomly allocated into two different groups: Polish and Optiglaze. For the Polish group, interim restorations were finished and polished with aluminum oxide finishers/polishers. For the Optiglaze group, one layer of nanofilled, lightpolymerizing protective coating was then applied. The 80 printed interim crowns were divided into 4 different groups depending on where they would be immersed: Artificial saliva, coffee, wine, and tea. After the sample allocations, there were 8 experimental groups. Each group was allocated with 10 specimens. Color measurements were obtained using a digital spectrophotometer in conjunction with The CIE L*a*b* system before the immersion and 6 months after the immersion. Two-way analysis of variance (ANOVA) was used to test the effects of surface treatment, immersion liquid, and their interaction on E at 6-month post-immersion. Fisher's protected least significant differences (LSD) was used as post hoc test to compare groups differences (α = .05). Results: There were significant effects of surface treatment [F(1,72) = 13.39, p = 0.000], immersion liquid [F(3,72) = 74.18, p = 0.000], and their interaction [F(3,72) = 16.33, p = 0.000] on E at 6-month post-immersion at the α = .05 level. The polish group showed significantly higher E than the Optiglaze group when immersed in coffee (p < 0.001) and wine (p = 0.015). The Optiglaze group showed significantly higher E than the polish group that was immersed in artificial saliva (p < 0.001). The wine group showed higher E than all other immersion liquid groups for both polish and Optiglaze surface treatments (p < 0.001 for all comparisons). L* showed a reduction that was significantly higher than the 2.0 acceptability threshold in the wine-polish (p < 0.001) and wine-Optiglaze (p < 0.001) groups.E showed a color change that was significantly higher than the perceptibility and acceptability thresholds for all the groups under polish surface treatment (p < 0.001).E also showed a color change that was significantly higher than the perceptibility and acceptability thresholds for artificial saliva, tea, and wine under Optiglaze surface treatment (p = 0.004). Conclusions: 3D-printed interim restorations showed significant discoloration after 6-months immersions in the artificial saliva and common beverages (including tea, coffee, and wine). Among all the chromogenic beverages, red wine caused the most signific...

Objective: Color and optical properties are particularly crucial to mimic natural tooth.This scoping review aimed to present an overview of the literature published on color and optical properties of 3D printing restorative polymer-based materials. The literature search was performed in MED-LINE/Pubmed, Scopus and Web of Science. Materials and methods:The literature search was conducted in the three databases based on the question: "Are the optical properties and color adequately reported on polymer-based 3D printing dental restorative materials studies?" with no restriction on year of publication. Data were reported and synthesized following PRISMA-ScR statement.Results: Nine studies fit the inclusion criteria. Five studies focused on evaluating only color stability; three articles assessed the color stability along with mechanical and morphological properties and only one study compared color parameters of 3D printed to conventional polymers. Two studies evaluated translucency parameter and no study was found evaluating scattering, absorption, and transmittance.Conclusions: Color and optical properties of 3D printed polymers that can be used in restorative dentistry are not adequately evaluated and characterized. Future studies on the influence of experimental printing conditions should include these physical properties to assist on improving esthetics.Clinical significance: This review shows the scarce literature existing on color and optical properties of 3D printing restorative polymer-based materials. These properties and their study are of outmost importance to create materials that mimic natural tooth to allow clinicians to obtain esthetically pleasant restorations.

“…Untersuchungen zur Randpassung und Dimensionstreue finden sich derzeit nur anekdotisch. Sowohl für die konventionelle festsitzenden Prothetik als auch in der Implantatprothetik lassen sich hieraus unter Zuhilfenahme des definitiven Designs kostengünstig in einem voll digitalen Workflow laborgefertigte Provisorien herstellen und somit auch die geplante Restauration ohne Risiken probetragen [14]. Passt das Design, kann dieses später ohne große Aufwendungen für die definitive Arbeit übernommen werden (▶ Abb.…”
