Article Abstract
Background: Optimal flexural strength is a critical prerequisite for materials used in fabricating prosthetic frameworks. The aim of this study was to evaluate and compare the Flexural strength (FS) of two CAD/CAM materials used in dental prostheses, namely polymethyl methacrylate (PMMA) reinforced with graphene (GCAM) and Monolithic Zirconia.
Materials And Methods: In this experimental study, 40 bar-shaped samples were manufactured by a milling machine and divided into two groups ( = 20/group): Group 1, GCAM; Group 2, Monolithic Zirconia. The specimens were subjected to a three-point bending test until fracture to evaluate Flexural strength. Data was statistically analyzed using an independent samples -test to compare the two groups at a 0.05 significance level.
Results: Compared to GCAM samples, each Monolithic Zirconia sample showed significantly higher values of flexural strength ( < 0.001).
Conclusion: The results show that GCAM is a promising material to be used for prosthetic purposes where less strength and greater resiliency are required.

Background Of The Study: known for its bioactive phytochemicals and antimicrobial potential; however, studies evaluating its outcome on the color, mechanical properties and antimicrobial activity of 3D-printed provisional dental resins are lacking. So this study evaluate the effect of seed extract incorporation on the color assessment, flexural strength, compressive strength, microhardness and antimicrobial activity of 3D-printed provisional crown and bridge resin.
Materials And Methods: A total of 240 samples were prepared, with 60 samples allocated to four groups based on 0 %, 1.

Electromagnetic pollution poses significant risks to electronic devices and human health, highlighting the need for mechanically robust, lightweight, and cost-effective electromagnetic interference (EMI) shielding materials. 3D-printed structures with nanomaterial-engineered surfaces offer a promising method for tailoring mechanical and electrical properties through multiscale design. Herein, we present a facile strategy for fabricating lightweight and flexible EMI shielding structures by chemical deposition of nanostructured metal coatings onto 3D-printed polymeric substrates.

Cemented paste backfill has made outstanding contributions to the large-scale consumption of phosphogypsum (PG), but poor water resistance significantly weakens the mechanical strength, promotes the leaching of total soluble phosphate (TP) and fluoride ions (F), and reduces its attractiveness in mine engineering. This research synthesized a curing agent (CA) using sodium methylsilicate, sodium silicate, and polyaluminum chloride (PAC). PG produced from Deyang Haohua Qingping Phosphate Mine Co.

This study provides valuable guidance for simplifying fabrication procedures and enhancing the structural integrity and safety of carbon fiber (CF) laminate transfemoral (TF) prosthetic sockets. While the high specific strength of CF laminate sockets offers advantages over conventional plastics, essential production data-their orientation-dependent strength and optimal cure conditions-are lacking, often requiring complex, costly cure cycles. This study investigated (i) the influence of fiber orientation on TF prosthetic CF socket strength via finite element analysis (FEA) during standing, and (ii) optimal single-step Vacuum-Bag-Only (VBO) cure conditions for prepreg in a low-cost conventional oven.

Direct in vivo mechanical assessment of cortical bone strength may address this diagnostic gap by capturing structural and material properties that govern whole-bone strength but are not reflected by BMD. We conducted a multicenter case-control study with cross-sectional assessment to compare ulna flexural rigidity, a biomechanical property correlated with whole-bone strength (R² ≈ 0.
