A Comparative Evaluation Of Flexural And Impact Strength Of Flexible And Other Denture Base Materials - An In Vitro Study

The material most commonly used in the construction of dentures is poly methylmethacrylate. This material is used because of its favorable working characteristics, processing ease, better accuracy, stability etc. Despite of these excellent properties, this material is not without limitations, particularly in terms of flexural and impact strength. The fracture of denture is rather a common problem & resistance to fracture of acrylic resin denture depends on the flexural and impact strength. The ongoing research, to improve their physical and mechanical properties has led to the introduction of high impact resins and flexible denture base resins. This study comparatively evaluates clinically significant properties of fracture resistance viz. flexural and impact strengths of a flexible denture base material with conventional denture base material and high impact denture base material that would help the clinician in solving the day to day problems of denture fracture and durability.
