It had been required to improve mechanical properties of hard crown and bridge resins. We had pointed out that mixing of PMMA powder with crosslinking agents for fablication of crown or bridges was not suitable to get better materials. Several trials were taken place to eliminate the PMMA powder. Hydrophobic colloidal silica was a good candidate to replace PMMA. But it is required to improve handling properties. A mixing of monomers, Bis-GMA and triethylene glycol dimethacrylate, and the silica was polymerized and pulverized and then the powder was applied for the fablication. The mechanical properties did not change as direct application of colloidal silica.
