Abstract

The invention discloses a medically efficient, nontoxic and non-side-effect organic silicon material for dental restoration. The organic silicon material is formed by mixing a component A with a component B according to the weight ratio being 1:1, wherein the component A comprises: 67 to 72 parts of first vinyl silicone oil, 217 to 229 parts of quartz powder, 70 to 75 parts of cyclohexanol alkynol, 33 to 36 parts of 50% of white carbon black and 50% of second vinyl silicone oil, 0.31 to 0.33 part of platinum catalyst and 0.78 to 0.82 part of PE (Poly Ethylene) mould releasing agent; and the component B comprises: 24 to 26 parts of the first vinyl silicone oil, 208 to 220 parts of the quartz powder; 69 to 73 parts of 50% of the white carbon black and 50% of the second vinyl silicone oil, 26 to 28 parts of silicone oil containing hydrogen, 15 to 17 parts of 2-bromine-4-cyano-6-methoxy phenyl ethyl ester, 0.02 to 0.03 part of chain-extended silicone oil containing the hydrogen and 36 to 39 parts of PE mould releasing agent. The organic silicon material is proper in vulcanization speed and convenient for impression.

Description

technical field [0001] The invention relates to a dental polymer material, in particular to a highly efficient, non-toxic and no side effect dental repair medical silicone material. Background technique [0002] Various types of shaping discs, such as clinical edentulous or partial edentulous, movable oral orthopedic devices, dental cranks, temporary tooth tissues, studio models, etc.; hospital stomatology departments for crowns, bridges, inlays, etc. during restoration Taking the impression requires the use of medical silicone material. However, the existing dental materials in the market use alginate and gypsum as dental materials, which are not easy to handle and need to be molded many times. Considering the particularity of the application of dental materials, some people also consider preparing medical silicone materials through on-site cross-linking reactions. But the difficulty of this method is to control the vulcanization speed. It should not be vulcanized too fas...
