CATIONICALLY CURABLE DENTAL MATERIALS |
摘要 |
The invention relates to a polymerizable dental material containing: (a) 3 to 80 wt. % of one or more cationically curable monomers; (b) 3 to 90 wt. % of one or more radio-opaque fillers; (c) 0.01 to 25 wt. % of initiators, retarders and/or accelerators, and; (d) 0 to 25 wt. % of auxiliary agents, whereby the cited percentages each refer to the total weight of the material. Filler (b) is produced by means of a melting method and is selected so that it has a refractive index of nD = 1.49 1.54, so that the viscosity of the polymerizable dental material, after a period of at least 9 months during which it was stored at a temperature ranging from 20 to 25 DEG C, has a value of +/- 50 % of the initial value measured 24 hours after the polymerizable dental material was produced, and so that the polymerizable dental material has a reactivity of the type that, once polymerization is initiated, the amount of the maximum heat flux generated by the dental material equals at least 0.8 mW/mg, and this maximum heat flux is attained within a period of no longer than 60 s. |
