In past, the materials used for denture bases were vulcanite, celluloid&phenol formaldehyde. Acrylic resins were introduced to dentistry in 1930's. There are certain limitations of acrylics like residual monomer allergy, poor mechanical strength, low fatigue strength, brittle on impact, poor conductors of heat, low hardness, high coefficient of thermal expansion, thermal shrinkage, poor color stability of self-cured resins, porosity, crazing, warpage, poor adhesion to metal and porcelain and requirement of mechanical retention. But still they are the most widely used denture base materials till date. But recently there has been much advancement in the field of denture base resins to overcome their drawbacks and to obtain an ideal denture base material. This article reviews the various advancements in the field of denture base resins.

Abstract


In past, the materials used for denture bases were vulcanite, celluloid&phenol formaldehyde. Acrylic resins were introduced to dentistry in 1930's. There are certain limitations of acrylics like residual monomer allergy, poor mechanical strength, low fatigue strength, brittle on impact, poor conductors of heat, low hardness, high coefficient of thermal expansion, thermal shrinkage, poor color stability of self-cured resins, porosity, crazing, warpage, poor adhesion to metal and porcelain and requirement of mechanical retention. But still they are the most widely used denture base materials till date. But recently there has been much advancement in the field of denture base resins to overcome their drawbacks and to obtain an ideal denture base material. This article reviews the various advancements in the field of denture base resins.
