Review on Resin Modified Core Build Up Materials

Abstract

The aim of the study is to evaluate and understand the importance of modification of resin based core build up materials in order to improvise the physical and chemical characteristics. The restorative materials should be able to restore the structural balance, functional efficiency and aesthetic harmony of the oro-facial structures. To fulfil these requirements, it must have the following properties: sufficient flexural strength to prevent core dislodgement during function; sufficient compressive strength to withstand intra-oral forces; biocompatibility with the surrounding tissues; ease of manipulation; capacity to bond to tooth structure; pins and posts; and dimensional stability. Most resin-based core build-up materials must be applied in increments to cure fully, however some materials, such as Bulk Flow materials and materials that release fluoride, such as Fluorocore, Absolute dentin core build-up composite, and Pulpdent Hardcore, may now be applied in bulk. It is concluded that evolution of core build up materials and it’s ability to match the structural and functional aspects of natural tooth structure is everlasting.
