| Summary, etc. | Aim: to assess the fracture resistance of interim restorations fabricated by 3D printing technique compared to milling technique. Methodology: Typodont model of maxillary 1st molar was preprared for full coverage crowns.The prepared model was digitally scanned by extraoral scanner. Duplication of master die into sixteen epoxy resin dies. Sixteen interim crowns were constructed by two techniques include: CAD/CAM technology using TelioCAD PMMA disc and 3D printing technology using Nextdent C&B resin material.The specimens were divided into 2 equal groups (n=8). All interim crowns were cemented on their corresponding resin dies using cementation loading device. All samples were subjected to thermal cycles(1250cycles,5-55c) and mechanical cycles (37,000cycles,50N). Using SEM to assess the surface topography for samples in both groups and EDX microanalysis was used to evaluate the elemental compositions with relative values expressed in wt% and K ratio.The specimens were loaded to failure in Newton (N) using universal testing machine. Stereomicroscope was used to investigate the fracture pattern. Data was statistically analyzed used Kolmogorov-Smirnov and Shapiro-Wilk tests & Student{u2019}s t tests (Ü = 0.05) and failure mode (%) by the Fisher exact test & chi2 test (p{u2264}0.05). Results: The mean ± SD values of fracture resistance were recorded for milled group (933.46 ±104.49 N) meanwhile the mean ± SD value recorded with printed group were (1226.48±48.33 N). It was found that printed group recorded statistically significant higher fracture resistance mean value than milled group |
