Effect of reinforcements on the flexural properties of acrylic resin

The fracture of acrylic resin dentures is a common clinical occurrence. Attempts to analyze and determine the causes of such fractures have received considerable attention in recent years. The clinician must often decide whether to repair or replace the broken denture. To minimize inconvenience to the patient and to save costs in the reconstruction of the dentures, quick and reliable denture repairs are often necessary. The use of auto-polymerizing acrylic resin generally allows for a simple and quick repair. However, the primary problem is its poor strength characteristics. Various methods for enhancing the strength of the repaired part have been reported This study was carried out to compare the effects of metal reinforcement and fiber reinforcement on flexural strength of the repaired acrylic denture base
