Meta Nexcore Core Build Up Material Post adhesions and core build-up in restoration Suitable viscosity and flow for post cementation and core build-up Dual curing: light-curing and self-curing are possible, so no need to worry about incorrect resin polymerization . When there isn’t enough natural tooth structure to support a crown, core build-up material is there to serve as a dentin replacement. These materials form a solid structure to support a crown following root canals or other procedures requiring large, deep preps. There is a wide range of options when it comes to choosing a core build-up material, but the dual cure varieties offer the assurance that any material too deep to be light-cured will still properly set up after self-curing. Here is a look at several of the dual cure core build-up materials currently available.
