Abstract:
The present invention discloses a cone material in endodontic treatment. The cone material comprises a thermoplastic polyurethane and a filler. The thermoplastic polyurethane is formed by a. isophorone diisocyanate (IPDI) or hexamethylene diisocyanate (HDI), b. poly(butyleneadipate) glycol (PBA) and c. chain extender, wherein the molar ratio of PBA and the diisocyanate is equal to or more than 0.8. By changing the molar composition of the components such as polyol and diisocyanate, physical and chemical property of the disclosed cone material in endodontic treatment can be adjusted.
