[Physical properties of adhesive 4-META resin cement (author's transl)]. 1981

4-Methacryloxyethyl trimellitate anhydride (4-META) had been reported to be a suitable monomer which promotes adhesiveness of PMMA rods with tooth substrates and metals. Previously an adhesive opaque resin which could eliminate mechanical retention devices from metal surface of crown and bridge metal frame was suggested. A new denture base resin, which is adhesive to metal denture plate, was also reported based on 4-META in MMA. We are going to publish a new application of 4-META to an adhesive dental cement in this paper. The physical properties of the new cement were measured: film thickness, 15 mu, tensile strength, 228 kg/cm2, compressive strength 920 kg/cm2, transvers strength , 530 kg/cm2, water sorption, 1.97 mg/cm2. Tensile adhesive strength of the cement was higher than 100 kg/cm2 between PMMA rods and dentine, enamel, dental alloys, and the stability was acceptable.
