The introduction of 3D printing technology in dentistry has opened new treatment options. ongoing development different materials for these purposes recently enabled the production definitive indirect restorations via printing. To identify relevant data, a systematic search was conducted three databases, namely PubMed, Scopus, and Web Science. Additionally, manual using individual terms performed. Only English, peer-reviewed articles that encompassed vitro or vivo research on mechanical properties 3D-printed composite were included, provided they met predefined inclusion exclusion criteria. After screening 1142 articles, 14 primary studies selected. included mainly utilized digital light processing (DLP) technology, less commonly stereolithography (SLA), once PolyJet technology. material various resins, such as VarseoSmile Crown Plus (VSC) Crowntec (CT), studied, including Vickers hardness, flexural strength, elastic modulus, compressive tensile fracture resistance, wear. aimed to compare behavior tested additive composites each other, conventional composites, subtractive-manufactured materials. This scoping review examined used restorations. aim provide comprehensive overview current knowledge this topic any gaps future research. findings suggest are not yet first option restorations, due their insufficient properties. Due limited evidence, more is needed area. Specifically, there need clinical trials long-term

The aim of this in-vitro study is to investigate the effect post-curing time and units on degree conversion (DC), microhardness (VHN) staining susceptibility (∆E00) two 3D printed permanent resins (Crowntec (SCT), Varseosmile CrownPlus (VSP)). A total 180 disc-shaped samples (10*10*2 mm), 60 for each experiment, from tested materials (30 SCT, 30 VSP) were printer. Half post-cured in LC-3DPrint Box other half Phrozen Cure V2 divided into 3 subgroups according 5, 10 min (n = 5). DC was determined using a Fourier transform infrared spectrometer. VHN values measured with Vickers hardness tester. color initially spectrophotometer then again after one month coffee. ∆E00 calculated CIEDE2000 formula. Data obtained parameter examined analyzed by SPSS software One-Way ANOVA, post-hoc Tukey, Tamhane's T2, Independent-samples T test Pearson's correlation (α 0.05).

Abstract Purpose This study aimed to evaluate and compare the fracture resistance of long‐span fixed provisional restorations fabricated using milling, three‐dimensional (3D) printing, conventional methods. Materials Methods Sixty specimens were prepared, divided into four groups 15 each, corresponding fabrication methods: computer‐aided design manufacturing (CAD‐CAM) milled resins, 3D‐printed permanent bis‐acryl reinforced with wire. The underwent a three‐point bending test universal testing machine measure resistance, quantified as maximum force (in Newtons). Statistical analysis was performed one‐way ANOVA Tukey's HSD post‐hoc tests across groups. Results Significant differences in observed among materials tested ( p < 0.001). Both CAD‐CAM resins exhibited significantly higher than method. Conclusion results highlight mechanical advantages digital methods for applications prosthodontics. These techniques may provide improved durability reliability, addressing demands complex restorations.
