研究概览
简要总结
Recently introduced, Hybrid resin polymer crowns are flexible, adaptable and durable in oral cavity. They are available as preformed crowns that offer properties of both SSC and zirconia crowns. These crowns are biocompatible, flexible and with a snug fit on the tooth. There is a scarcity of literature available on Hybrid resin polymer crowns comparing to the crowns traditionally available. Therefore, the aim of this study is to clinically evaluate and compare SSC crowns and Hybrid resin polymer crowns in primary molars.
