In 1978, Kuraray introduced “Clearfil Bond System F”, the world's first total etching adhesive system, and then made improvements to the total-etching procedure and launched “Clearfil New Bond” and “Clearfil Photo Bond”. Following the development of “Clearfil Liner Bond System”, a mild etching/primer system, we introduced “Clearfil Liner Bond II”, the first total self-etching bonding system in the world. Moreover, we have developed “Clearfil Liner Bond IIΣ” which has designed for multiple uses, and “Clearfil Mega Bond”, which has designed to improve manipulation. Also, we have made an experimental product called “ABF”, a fail-safe system that contains an antibacterial monomer and fluoride releasing compound.
Furthermore, we have applied its adhesion technology to the development of adhesive resin cements and have developed “Panavia EX”, “Panavia Fluorocement”, and “Panavia F 2.0”, improving cementing function with the introduction of each new product. Also, as a response to the diversification of restoration materials, we have introduced such product as, “Porcelain Bond”, a ceramic surface treating agent, and “Alloy Primer”, a metal surface treating agent.
In this manner, we have been able to develop products with better functions because of advances in key technologies. This article deals with the molecular design involved in our key technologies.
