Abstract
The present invention provides a dental polymerizable composition which has excellent handling property by the brush-dip technique and the bulk-mix technique, particularly excellent handling property by the brush-dip technique, contains few air bubbles, is excellent in color tone, polishability, mechanical properties and the discoloration resistance of a cured product at the time of curing and is used for many purposes such as the repair of a denture base or artificial tooth, a tooth crown prosthetic restoration and a temporary prosthetic restoration which is used until a bridge is completed when it is a two-composition type self-curing resin. The dental polymerizable composition comprises three different types of (meth)acrylate polymer particles, each having specific particle size characteristics and specific molecular weight characteristics.
