Background: The adoption of 3D printing in restorative dentistry is increasing, with the post-curing duration a material being identified as key determinant its performance. This study evaluated effect post-polymerization time on flexural strength (FS) and Vickers microhardness (VHN) 3D-printed composite. Methods: Specimens Formlabs Permanent Crown Resin were printed divided into four groups according to their time: no 20, 40, 60 min time. Flexural testing was carried out using three-point test 40 bar-shaped specimens (n = 10/group), followed by fractography observations under scanning electron microscope (SEM). Vicker also conducted disk-shaped 10/group). inorganic filler content measured ash method, morphology characterized an SEM. Statistical analyses performed adjusted ANOVA regression tests. Results: highest median FS values observed at (133.07 MPa), significant differences across all (p < 0.0001). VHN found (32.09 VHN), between A positive correlation (rho 0.7488; p 0.0001) hardness changing durations. resin composite had average 66.82% based weight. Conclusions: With limitation current vitro setup, shown lead best post-printing polymerization significantly affects Resin. Further research should explore effects different compositions, clinical conditions, curing protocols enhance general applicability these findings. Clinical implications: Extending does not inherently result improved properties. considered adjustment can impact mechanical properties

Abstract Background Controversial properties and performance of commercially available 3D-printed resin composite for permanent restorations. So, the purpose this study was to assess flexural strength, microhardness, wear, color stability versus milled nanohybrid composites restoration. Methods A total 70 samples were used; 38 bar-shaped (14 mm ⋅ 2 mm) 32 disc-shaped (10 Tetric CAD ™ blocks (TC) Flexcera Smile Ultra plus (FSU) fabricated ( n = 35). Flexural tested using 3-point bending test. The Vickers test used microhardness evaluation. Volumetric wear analysis changes assessed after simulated aging via Geomagic Control X software a Vita Easyshade spectrophotometer, respectively. Color calculated CIEDE2000 formula. paired t-test dependent variable analysis, Mann‒Whitney U independent variables (α 0.05). Results TC resulted in significantly higher strength (247.7 ± 29.1 MPa) (94.6 3 gf/um ) than did FSU (97.2 10.2 MPa 31 4.6 2, respectively) P < 0.0001). Compared with (–36.3 ), lower rates (–17.6 )( had ΔE00 value 2.4 0.5, whereas 2.1 0.7 0.532), no significant difference between groups, but both values above acceptability limit (1.8). Conclusions composites, have better properties. Clinical relevance Milled exhibit superior resistance, making them potentially more durable clinical dental restorations compared composites.

ABSTRACT Objective To compare the mechanical, chemical, and surface properties of three materials used for provisional restorations, manufactured with additive (3D‐printing), subtractive (milling), conventional techniques. Materials Methods Three material groups were tested: (a) GC TempPRINT, (3D‐printed/3DP), (b) VITA CAD‐Temp, (milled/ML), (c) Telio CS C&B, (conventional self‐cured/CC). Each group consisted 20 beam‐shaped specimens (25 × 2 mm) a three‐point flexural strength test 5 discs (Ø:15 mm, h: roughness, gloss, degree conversion, hardness measurements. Data analyzed using one‐way ANOVA Holm‐Sidak multiple comparison tests ( α = 0.05). Results The ranking statistically significant differences p < 0.05) was: 3DP >CC > ML (Sdr roughness parameter), (gloss) 3DP> CC (gloss, strength). Clinical Significance tested showed in all properties. These may affect their clinical performance should be taken into consideration application.
