Flexural strength of heat-polymerized polymethyl methacrylate denture resin reinforced with glass, aramid, or nylon fibers

Abstract

Within the limitations of this study, the flexural strength of heat-polymerized PMMA denture resin was improved after reinforcement with glass or aramid fibers. It may be possible to apply these results to distal extension partial denture bases and provisional fixed partial dentures.

Comparative Study of Transverse Strength and Water Sorption between Conventional and Fiber Reinforced Denture Base Resins – An in Vitro Study

“…Different types of fibers like Glass, Aramid, Nylon, Polyethylene, Carbon and Kevlar are available and among these fibers, glass fibers are commonly available. Previous studies 1,7 have…”

“…In the present study, glass fibers have been chosen for the reinforcement of conventional and high impact strength denture base resins. Glass fiber reinforced dentures are much stronger and more resilient under flexural fatigue or impact stress conditions and also absorbs less water content than conventional and high impact strength resin dentures and hence the chances of fracture of the denture can be substantially eliminated 1 .…”

“…PMMA continues to be used because of its working characteristics, ease of processing, accurate fit, stability in oral environment, superior esthetics, use with inexpensive equipments and adequate mechanical properties. 1 Most fractures of the denture occur inside the mouth during function, primarily because of resin fatigue. 2 The denture base resin is subjected to various stresses during function; these include compressive, tensile and shear stresses.…”

Effect of Denture Cleansers on Flexural Strength, Color Stability and Surface Roughness of Flexible and Microwave cured Acrylic Resin

“…Therefore, the choice of appropriate methods for denture cleaning is clinically important, when the objective of the procedures is not to cause surface damage of the denture base, and for daily use to prevent microbial adhesion. Moreover, fracture of an acrylic denture base is a common problem and occurs during masticatory function because of base deformation and consequent resin fatigue 19 . Immersion in denture cleansers and disinfecting solutions may decrease the flexural strength of acrylic resins 20,21 .…”

Polyamide as a denture base material- a review

“…These often lead to denture failure during chewing or when fall out of the patient's hand. In order to enhance some properties of PMMA, various efforts have been taken including addition of metal wires or plates, fibers, [3][4][5][6] metal dification of chemical structure. In recent ted attention as a denture base materials.…”
