Flexural Strength and Flexural Modulus of Fiber-Reinforced, Soft Liner–Retained Implant Overdenture

The International Journal of Prosthodontics, 2021
To compare the flexural strength and modulus of ball-soft liner–retained overdentures vs ballsocket– retained overdentures, as well as to evaluate the effect of using glass fiber reinforcement on the mechanical properties of ball-soft liner–retained overdentures.A total of 80 overdenture specimens were fabricated and divided equally into four groups (n

Flexure Modulus of Orthodontic Stainless Steel Wires

Journal of Dental Research, 1981
The flexure modulus of elasticity of standard stainless steel orthodontic wires was determined by the use of an iterative finite element technique to be 25.4 x 106 psi (175 x 103 MN/m2). This technique accounts for the configurational changes in the test specimens due to the relatively large deflections during the cantilever test.

A Comparison of the Flexural and Impact Strengths and Flexural Modulus of CAD/CAM and Conventional Heat-Cured Polymethyl Methacrylate (PMMA).

Journal of Prosthodontics, 2018
PURPOSE The introduction of computer-aided design/computer-aided manufacturing (CAD/CAM) technology to the field of removable prosthodontics has recently made it possible to fabricate complete dentures of prepolymerized polymethyl methacrylate (PMMA ...

The Flexure Modulus of Elasticity of Orthodontic Wires

Journal of Dental Research, 1983
The flexure moduli of elasticity of solid and multi-stranded orthodontic wires were determined. Results for the solid wires approximated their tensile values, but the differences were statistically significant for the stainless steel, chromium-cobalt-nickel, and nickel-titanium alloys. The flexure moduli of the multi-stranded wires ranged from 0.89 to

Biaxial disc flexure – modulus and strength testing

British Ceramic Transactions, 1999
There is widespread use of biaxial testing of ceramics, but relatively little information concerning the accuracy of testing, and the pitfalls that can arise unless the test is carefully prescribed. The present paper reviews recent work in measuring elastic moduli using a biaxial natural frequency method, and in investigating some of the potential ...

Biaxial flexural modulus of antibiotic‐impregnated orthopedic bone cement

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2007
AbstractPreviously reported antibiotic‐impregnated cement strengths have been based on uniaxial and fatigue testing methodologies. These methods may not provide an accurate characterization of bone cement's true load‐bearing capacity in total joint replacement (TJR).

Hardness, Flexural Strength, and Flexural Modulus Comparisons of Three Differently Cured Denture Base Systems

Journal of Prosthodontics, 2008
Abstract Purpose: This study compared the surface hardness, flexural strength, and flexural modulus of a light‐ and heat‐cured urethane dimethacrylate (UDMA) to two conventional polymethyl methacrylate (PMMA) denture base resins. The effect of less‐than‐optimal processing condition on the hardness of internal and external surfaces of UDMA specimens was

Studies on the flexural modulus of structural foams

Journal of Polymer Research, 1994
An investigation based on I-Beam models was undertaken in this paper for extending knowledge regarding the flexural modulus of structural foam. The applicability of five I-Beams models (I-Beam A, B, C, D and E) including a newly developed one (I-Beam E) were investigated in this work.
