CALCIUM SILICATE CEMENT KIT, CEMENT DELIVERY SYSTEM, CEMENTED MATERIAL Russian patent published in 2024 - IPC A61K6/853 A61C5/60 

FIELD: medicine, dentistry.

SUBSTANCE: invention relates to dental compositions capable of self-curing. A kit is proposed for a self-curing calcium silicate cement for treating a bone and/or tooth disorder or disease in a subject in need of such treatment, comprising a first container and a second container, wherein the first container is water-resistant and contains a semi-solid anhydrous calcium silicate phase including particles calcium silicate, a non-aqueous carrier which is an anhydrous liquid phase, and optionally a radioopaque agent, and the second container contains a semi-solid aqueous phase comprising 10 to 50% purified water, 10 to 50% radioopaque agent and 10 to 75% curing accelerator by weight of the total weight of the aqueous semi-solid phase, while the ratio of the volume of the semi-solid anhydrous calcium silicate phase to the volume of the semi-solid aqueous phase is from 1 to 10, also the first and second containers do not contain phosphorus compounds, where the aqueous semi-solid phase is semi-solid calcium silicate phrase have a viscosity from 10 to 10⁵ Pa at 25°C; a delivery system for self-curing calcium silicate cement containing the proposed kit, and a cured dental material for tooth and/or bone regeneration, which is obtained using the proposed kit or the proposed delivery system.

EFFECT: provision of a means for easy delivery of a calcium silicate-based cement composition in the form of a homogeneous paste characterized by good processing properties and a suitable water content for effective curing.
