What changed
This document is a USPTO patent application (US20260083644A1) filed on September 23, 2025, by Naoya Kitada, Rei Nishimura, and Yusuke Miyashima. It describes a novel production method for dental polymerizable compositions or intermediates that are substantially free of filler and achieve excellent storage stability. The method utilizes a production machine without a stirring blade, disposing a composition comprising a polymerizable monomer and a polymerization inhibitor in a container with a specific empty space rate (10-90%) and then operating the container.
This patent application is primarily informational and does not impose immediate regulatory obligations on companies. However, it signals potential advancements in dental material technology. Companies involved in the research, development, or manufacturing of dental materials, particularly polymerizable compositions, should be aware of this filing as it may influence future product development and intellectual property strategies in the sector.

Abstract
An object of the present invention is to provide a production method that can provide a dental polymerizable composition (β) or a dental polymerizable composition intermediate (γ), having excellent storage stability, in high yield. A method for producing a dental polymerizable composition (β) or a dental polymerizable composition intermediate (γ), which is substantially free of a filler, using a production machine that is substantially not equipped with a stirring blade and equipped with a container, the method comprising the steps of disposing an composition (α) comprising (a) a polymerizable monomer and (b) a polymerization inhibitor in the container such that an empty space rate of the container is 10 to 90%; and operating the container.
