Key statement: The present invention is directed to the functionalization of butyl rubber ionomer and optionally the grafting of polyamide to halobutyl rubber ionomers.
The second volume is devoted to aspects of applications, among them, fluoroalkyl acrylate polymers and their applications, fluoroplastics and fluoroelastomers: basic chemistry and high-performance applications, the commercial synthesis and applications of poly(vinylidene fluoride), fluoridated ionomers and ionomer membranes: monomer and polymer synthesis and applications, and fabricating flexible transparent nanohybrids with heat-resistant properties using a fluorinated crystalline polymer.
Regardless of the development of various materials, the glass ionomer cement (GIC), due to its anticaries effect and ability to release fluoride still remains the routinely used material in dentistry.
Glass ionomer cements lack the aesthetics and physical properties of composite resin, however they bond chemically onto tooth structures, do not undergo polymerization shrinkage (no marginal stress) and the fluoride release protects cavo marC.
One of the methods designed to reduce shrinkage stress is use of low-elastic modulus liners like glass ionomer cements, resin-modified glass ionomer cements and flowable composites under the composite.
Abstract: A randomized, double-blind, split-mouth clinical trial was performed compared the desensitizing efficacy of the resin-modified glass ionomer cement (GIC) ClinproTM XT (3M ESPE, Minnesota, USA) and the conventional GIC Vidrion R (SS White, Gloucester, UK) in a 6-month follow-up.
There are two primary classes of sealant materials: filled or unfilled resin-based sealants and glass ionomer cements (Table I).
The purpose of this in vitro study was to compare the shear bond strength of mineral trioxide aggregate and glass ionomer cement by Instron testing machine.
Films made with the ionomer in the seal layer had the best overall physical properties, including impact resistance, and the highest machine-direction tear resistance--a desirable attribute once the bag is opened.
