BACKGROUND Repeated fracture of the denture base is a common problem in prosthodontics, and it represents a nuisance and a time sink for the clinician. Therefore, the possibility of increasing repair strength using new reinforcement materials is of great interest to prosthodontists. AIM OF THE STUDY This study aimed to evaluate the effects of incorporation of zirconia nanoparticles (nano-ZrO2...

Open-cell and closed-cell metal foams have been reinforced with different kinds of micro- and nano-sized reinforcements to enhance their mechanical properties of the metallic matrix. The idea behind this is that the reinforcement will strengthen the matrix of the cell edges and cell walls and provide high strength and stiffness. This manuscript provides an updated overview of the different manu...

in the present work, high temperature tensile properties of medium density polyethylene (mdpe) and its nanocomposites are investigated. for this purpose mdpe reinforced with different weight percentages of nano-sized calcium (2, 5, 10) are produced by compression moulding method. tensile tests have been carried out at different temperatures, i.e. 30, 60, 90c using thermomechanical analysis (tm...

Introduction and Background: Ceramics are inorganic, nonmetallic materials, such as alumina, beryllia, or glassceramic, whose final characteristics are produced by subjection to high temperatures. Nanomaterials is a rapidly growing area of ceramics [1-3] and can be classified into the following categories: Nano-particles submicron or ultra micron size particles; Nano-fibers – nanometer (nm) siz...

An experimental study conducted to evaluate the hardened and durability characteristics of ternary blended concrete containing Nano-Silica Zeolite along with steel fibers act as micro- reinforcement has been presented in this paper. were included different dosages optimum combination above two materials (Nano-Silica -1% Zeolite- 10%) obtained through trails from viewpoint workability strength. ...

Poly methyl methacrylate (PMMA) is the dominant acrylic that widely used to produce partial and complete dentures. Denture fractures are caused by fatigue owing repetitive masticatory, flexural impact loads produced dropping. The mechanical properties of dentures have been developed reinforcing with various agents like rubbers, fillers fibers. Progressively, novel dental materials reinforcement...

In this work, a Mg-5Nb metal–metal composite was reinforced with nano SiC (SiCn) ceramic reinforcement of varying volume fractions, using the disintegrated melt deposition technique. The extruded Mg-5Nb-SiCn composites were characterized for their microstructure and mechanical properties. Based on the results obtained, it was observed that the volume fraction of nano-SiC reinforcement played an...
