AI Technical Summary

Technical Problem

Conventional water-setting dental cements suffer from insufficient fracture toughness, which compromises their durability and performance under chewing loads, and existing improvements, such as adding polymerizable components, often reduce biocompatibility.

Method used

A water-setting dental cement comprising an acid-reactive powder, a polyprotonic acid, and dispersed polymer particles, particularly polymer particles with ionic and/or sterically stabilizing groups, is developed to enhance fracture toughness without compromising other properties like biocompatibility.

Benefits of technology

The cement exhibits improved fracture toughness, leading to increased durability and resistance to cracking, while maintaining or enhancing other performance characteristics like consistency, working time, and biocompatibility.
