Biological and Chemo-Physical Features of Denture Resins

Abstract

In the dental field, the study of materials has always been the basis of the clinical practice. Over the years, with the evolution of materials, it has been possible to produce safe and predictable prosthetic devices, with ever better aesthetic features, biocompatibility and patient satisfaction. This review briefly analyzes the features of dental resin materials to underline the biological, microbiological and chemo-physical characteristics. The main aim of prosthodontics is to rehabilitate patients and therefore improve their quality of life. Dental resins are the main materials used for the production of dentures. Once solidified, these polymers have different mechanical or surface characteristics. The results of the literature on these characteristics were analyzed and some new brand dental resins, known as modern resin, were subsequently evaluated. The new materials are undoubtedly a step forward in the creation of dental prostheses, and also in all subsequent maintenance phases. This review shows how changing the chemical structure of the resins could have microbiological influences on the growth and management of the biofilm, and also physical influences in terms of its mechanical characteristics. The development of new materials is a constant goal in dentistry in order to obtain increasingly predictable rehabilitations.

Impact of Surface Changes and Microbial Adhesion on Mucosal Surface Finishing of Resin Denture Bases by Shot Blast Polishing Using Viscoelastic Media

“…Therefore, to reduce the Ra of the mucosal surface of denture bases, a treatment method that improves the surface texture of the working model is required in the future. On the other hand, methods that suppress the adhesion of microorganisms by treating the surface of denture bases have been reported [ 27 , 28 , 29 , 30 , 31 ]. A method of adhering or mixing nano-silver particles and a method of using a 2-methacryloyloxyethyl phosphorylcholine polymer or titanium dioxide for a resin base have been examined and are being applied to clinical settings.…”

Effect of Different Surface Modifications of Acrylic Teeth and Thermocycling on Shear Bond Strength to Polycarbonate Denture Base Material

“…Synthetic resin is a wide class of polymers. Phenolic resins, acrylic resins, epoxy resins, unsaturated polyester resins, vinyl ester resins, thermoplastic resins, thermosetting resins, and elastomers are among the prevalent resins [2].…”

Comparative Evaluation of Compressive Bond Strength between Acrylic Denture Base and Teeth with Various Combinations of Mechanical and Chemical Treatments

“…Geriatric patients often seek the replacement of missing natural teeth (partial or complete) to restore speech, function, and esthetics. A durable, strong, and biologically acceptable denture necessitates the use of a favorable and superior-quality denture base [1]. Polymethyl methacrylate (PMMA) has been widely used for manufacturing denture bases in conglomeration with artificial teeth for a variety of prostheses.…”
