  • Process for producing a dental shaped part by stereolithography
    Patent number: 9387056
    Abstract: The invention relates to the use of a composite resin composition comprising (a) at least one polyreactive binder, (b) a first photopolymerization initiator having an absorption maximum at a wavelength of less than 400 nm, (c) a second photopolymerization initiator having an absorption maximum at a wavelength of at least 400 nm and (d) an absorber having an absorption maximum at a wavelength of less than 400 nm, for the stereolithographic production of a dental shaped part based on composite resin. The invention also relates to a process for the stereolithographic production of a dental shaped part and the use of the composite resin composition in this process.
