MUMBAI, India, Aug. 8 -- Intellectual Property India has published a patent application (202527062837 A) filed by Consiglio Nazionale Delle Ricerche; and Friedrich-Alexander-Universitat Erlangen-Nurnberg, Roma, Italy, on July 1, for 'composite material based on bioactive glass and amorphous calcium phosphate, and process for producing same.'
Inventor(s) include Degli Esposti, Lorenzo; Iafisco, Michele; Boccaccini, R.; and Zheng, Kai.
The application for the patent was published on Aug. 8, under issue no. 32/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to an amorphous calcium phosphate/bioactive glass composite material (ACP/BG). This composite material possesses both the short-time ion release capability of ACP as well as the long-time ion release of BG and thus (i) efficiently remineralizes damaged enamel, and (ii) induces the formation of a new HA layer onto enamel and dentin surface. The ACP/BG composite material is obtained by embedding BG particles in a matrix of ACP nanoparticles in order to maximize homogenization between the two components and to produce a composite with high uniformity from the macro- to the nano-scale. This has been achieved with a process that includes a step of precipitating ACP onto BG particles. The BG particles can be nano-, micro-, or macro-particles. The particles can also be porous or mesoporous The invention relates also to the use of the composite material of the invention for use in the prevention of dental demineralization and to boost remineralization. In other words, the composite material here disclosed is used as remineralizing agent thanks to its ability to restore the structure and preserve the mechanical properties of dental hard tissues by releasing Ca2+ and PO4 3- ions, thereby mimicking the spontaneous remineralization process induced by saliva. The composite material can also be used for bone regeneration."
The patent application was internationally filed on Dec. 20, 2023, under International application No.PCT/IB2023/062999.
