Title:
DENTAL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/138973
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a dental composition that exhibits little polymerization shrinkage stress and an excellent mechanical strength. The present invention relates to a dental composition comprising a compound (A), a monomer (B) that exhibits a solubility in acetone at 25°C of at least 50 g/L, and a polymerization initiator (C). The compound (A) has a weight-average molecular weight of 1,000-80,000, includes a Tg of less than 40°C, and has a solubility in acetone at 25°C of less than 50 g/L. The compound (A) preferably comprises a compound that has a polymerizable group.
