Flexural properties and finite element analysis of novel 3D-printed ceramic materials via 3D-LCM technology.

Background: This study evaluates the mechanical properties of dental crown prosthodontic materials by investigating the flexural strength and stress distribution of various ceramic materials, including milled zirconia and two ceramics fabricated using LCM technology, employing Finite Element Analysis (FEA).

Methods: Seventy-five samples were divided into five groups: milled zirconia, Zirconia-210, Zirconia-230, Alumina-350 and Alumina-500. Flexural strength tests, including three-point bending, Weibull analysis and FEA, were conducted to analyse stress distribution.

Mechanical properties of a resin-modified glass-ionomer cement reinforced with short-glass fiber flowable resin composites.

Purpose: To evaluate the improvement of selected mechanical properties of a resin-modified glass-ionomer cement (RMGIC) with a discontinuous short E glass fiber flowable resin composites (GFRRC) to be used in load-bearing areas of permanent teeth.

Methods: Experimental materials were prepared using two different weight proportions, 7 wt% (1.75% E glass fibers) and 25 wt% (6.

Mechanical and Biocompatibility Properties of 3D-Printed Dental Resin Reinforced with Glass Silica and Zirconia Nanoparticles: In Vitro Study.

This study aimed to assess the mechanical and biocompatibility properties of dental resin reinforced with different nanoparticle additives. Temporary crown specimens were 3D-printed and grouped based on nanoparticle type and amount, including zirconia and glass silica. Flexural strength testing evaluated the material's ability to withstand mechanical stress using a three-point bending test.

The Clinical Potential of 3D-Printed Crowns Reinforced with Zirconia and Glass Silica Microfillers.

The development of 3D-printed crown resin materials with improved mechanical and physical properties is an area of growing interest in dentistry. This study aimed to develop a 3D-printed crown resin material modified with zirconia glass (ZG) and glass silica (GS) microfillers to enhance overall mechanical and physical properties. A total of 125 specimens were created and divided into five groups: control unmodified resin, 5% either ZG or GS reinforced 3D-printed resin, and 10% either ZG or GS reinforced 3D-printed resin.
