A recently granted patent (Publication Number: US11925697B2) discloses a novel photocurable dental impression material designed for dental applications. The material comprises a mixture of polymerizable silicone compounds with two or more polymerizable (meth)acrylate groups, a filler, and a photo initiator system. The unique aspect of this material lies in the specific composition of the polymerizable silicone compounds, with a defined ratio of high-molecular and low-molecular weight compounds to optimize performance.

Furthermore, the patent details the inclusion of additional polymerizable (meth)acrylates or (meth)acrylamides in the composition, along with specific formulas for the polymerizable silicone compounds and the photo initiator system. The material's viscosity, filler particle size, and packaging options are also specified in the patent claims. The method for preparing a dental impression using this material involves taking an impression of a dental structure and curing the material with light within a specific wavelength range. Overall, this patented dental impression material offers a tailored solution for dental professionals seeking efficient and effective impression materials for their practice.
