Stable one part dental compositions employing ipn technology

摘要: Compositions hardenable by exposure to heat or electromagnetic radiation are provided dissolving together form a blend from about 0% 50% weight of an uncrosslinked polymer, 2% 30% polymerizable monomer, 10% 70% crosslinked polymer in the discrete particles having average diameters 0.001 micron 500 microns and being swollen said solution 20% crosslinking agent for monomer. Such compositions exhibit superior chemical physical characteristics when hardened suitable wide variety applications as construction media. especially production prosthetic dental appliances, such as, example, teeth. It is believed that hardening during preparation appliances forms system known interpenetrating network.
