Hydrolysis-resistant and stress-buffering bifunctional polyurethane adhesive for durable dental composite restoration
A new elastic polyurethane (PU) adhesive was reported in this study to improve the stability and durability of the dental adhesion interface.A polyurethane oligomer was synthesized by the solution polymerization method, and a diluent and solvent were added to prepare PU adhesives.The water sorption, water solubility, contact angle, thermal stabilit
