[0019] Embodiment 1 provides a kind of impression material that is used for dental denture, is made of the following components of weight ratio:

[0020]

[0021] A method for preparing an impression material for dental dentures, comprising the following steps:

[0022] Step 1, mixing step: mix and grind natural gypsum, hydroxyapatite, then add and mix disodium succinate;

[0023] Step 2, pressurized firing: pressurize and fire the mixture obtained by said mixing step; at 20Kg / cm 2 The mixture obtained through the mixing step was pressurized for 24 hours under pressure, and the mixture was fired at a temperature of 150°C.

[0024] Step 3, grinding: adding thermosetting resin, potassium sulfate and sodium lauryl sulfate to the product obtained through the pressure firing step, and grinding. Preferably, the size of the ground product in step 3 is 0.3mm-0.5mm.

[0025] The Young's modulus reflects the rigidity of the material. The larger the Young's modulus, the less prone ...

Abstract

The invention relates to a mold-picking material for dental denture and relates to the technical field of dental restoration. The problem that the main ingredient of an existing mold-picking material is gypsum and gypsum has poor strength and the problem that a gypsum mold is easy to damage during the mold-picking process due to experience problems and moulding time is long and moulding cost is high need to be solved. The mold-picking material for dental denture is characterized by being prepared from the following ingredients, by weight, 15-35 parts of natural gypsum, 3-8 parts of hydroxyapatite, 10-25 parts of disodium succinate, 10-20 parts of potassium sulfate, 6-25 parts of sodium dodecyl sulfate and 12-25 parts of thermosetting resin. In a preferred embodiment, the thermosetting resin is at least one component selected from a group consisting of melamine resin, phenolic resin, epoxy resin, polyurethane resin and polyester resin.

Description

technical field [0001] The invention relates to the technical field of tooth restoration, in particular to an impression material for dental dentures. Background technique [0002] Dental caries (dental caries) is a progressive lesion of dental hard tissue caused by the compound action of various factors in the oral cavity. It is the main common disease of the oral cavity, and it is characterized by high incidence and wide distribution. The World Health Organization has listed it together with cancer and cardiovascular disease as the three major human diseases. [0003] Microorganisms in the oral cavity (such as Streptococcus mutans) form dental plaque on the surface of the enamel, and through processes such as acid production, repeated acid etching and demineralization of the enamel, the enamel is destroyed, and then the dentin is destroyed. Clinically, caries is often divided into three stages according to the degree of caries: superficial, medium and deep caries. Superf...
