MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541133860 A) filed by Pondicherry University, Puducherry, India, on Dec. 30, 2025, for 'a method of preparation of plant based resin polymer as denture material and preparation thereof.'
Inventor(s) include Dr. A. Hannah Rachel Vasanthi; Mrs. Saranga; and Dr. N. Selvasudha.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a novel denture material composition and method of preparation thereof for restorative dental applications. The composition comprises poly (methyl methacrylate) (PMMA) blended with a resin fraction isolated from jackfruit (Artocarpus heterophyllus) latex. The resin is prepared by solvent extraction using methanol and n-hexane, followed by phase separation, residual solvent removal, and concentration to yield a biologically active fraction containing silane groups and secondary metabolites. The denture material is fabricated by dissolving PMMA in acetone and resin in methanol, blending the solutions under controlled stirring, and allowing self-curing without external heating or curing agents. The resulting composite exhibits enhanced tensile strength, microhardness, thermal stability, and reduced water sorption compared to PMMA alone. Additionally, the material demonstrates antioxidant, antimicrobial, and antibiofilm properties, with reduced cytotoxicity and improved biocompatibility in vitro and in vivo. The invention provides a cost-effective, sustainable, and multifunctional dental restorative material overcoming limitations of conventional PMMA."
