▎ 摘　　要

NOVELTY - Temporary crown and bridge repair material, comprises 100 pts. wt. methyl methacrylate, 30-60 pts. wt. composite inorganic filler, 0.01-1 pt. wt. initiator and 0.01-3 pts. wt. toner. The composite inorganic filler is at least two of zero-dimensional inorganic fillers, one-dimensional inorganic fillers, two-dimensional inorganic fillers and three-dimensional inorganic fillers. USE - Used as temporary crown and bridge repair material. ADVANTAGE - The temporary crown and bridge repair material: by using the above composite inorganic fillers, can reduce the polymerization inhibition of the filler itself, can increase the filling amount of the filler, thus has improved mechanical properties through the synergistic effect between the fillers of different dimensions; has high flexural strength and hardness, and low water absorption and solubility values. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing temporary crown and bridge repair material, comprising (i) mixing silane coupling agent and methyl methacrylate, adding initiator to carry out polymerization reaction; (ii) adding toner and composite inorganic filler and mixing uniformly to obtain a mixture; (iii) injecting the mixture into a mold, and performing curing and molding to obtain final product.
