Resin-modified MTA-based material “ Super MTA Paste ” using TBB as a polymerization initiator

Abstract

We developed a novel MTA-based material that exploits advantages of both tri-n-butylborane (TBB) and MTA. In August 2019, we launched the resin-modified MTA-based material called “ Super MTA Paste ” . Unlike hydraulic MTA-based materials, Super MTA Paste does not require mixing with water or curing with a cotton ball. Curing of this material is driven by chemical polymerization initiated by TBB. We have adopted a high-purity dental white Portland cement that was developed and synthesized in Japan. Super MTA paste is a material that has not only easy operability and marginal sealing properties of resin-based materials, but also high biocompatibility by combining TBB and high-purity dental white Portland cement.
