The evaluation of new dental resins prepared with polyfunctional methacrylate monomers.
The combinations of several composite fillers and dimethacrylates for crown and bridge resins were investigated. The composite filler prepared from TMPT markedly improved the mechanical and physical properties of crown and bridge resins. The enhancement of the mechanical and physical properties is due to the highly crosslinked structure which is developed with the use of the reactive composite filler which copolymerizes with the matrix monomer. The combination of the 2.6E-UDMA comonomer and the TMPT composite filler exhibited the maximum compressive strength, transverse strength, and Brinell hardness, and minimum abrasion loss and thermal expansion. This hard resin was superior to the resins currently available for clinical use.
