Background: The selection of restorative materials for fabrication of crown and bridge which delivers less amount of stress to the periodontium is a challenging job for successful dentist. The resiliency of crown material plays a pivotal role in delivering stress to the periodontium and supporting structures. Aim: To evaluate the amount of stress transmitted to tooth and periodontium with different restorative crown materials with different magnitude and direction of load. Materials and method: Stress distribution is studied on seven different types of restorative crown materials on the natural tooth mounted on the photoelastic model. Results: In photoelastic study the stress distribution is assessed by fringe order and fringe value. The highest stress inducing crown materials have highest fringe value. The study result shows metal ceramic restoration exhibits highest stress distribution followed by nickel chromium, silver palladium, gold, IPS empress 2, targis vectris. The least stress transferred to the periodontium was by acrylic resin. Conclusion: The heat cure acrylic resin and the modified resin targis vectris have found to be the material of choice for complete coverage as far as stress concentration on the supporting structures is concerned.
