Problems solved by technology

The disadvantages of this method are: 1. The physical and chemical properties of resins, alloys, ceramics, etc. are different from those of the teeth themselves, and the biocompatibility is not good, and the mechanical properties cannot reach the strength of the enamel itself; 2. The steps of mechanical treatment will remove some The part of healthy enamel that is not infected, but instead enlarges the cavity and reduces the part of natural enamel

Embodiment 1

[0024] Embodiment 1, the preparation of dental restorative material

[0025] Take isolated human molars or wisdom teeth, use the side of the saw blade of a low-speed diamond cutter to gently grind the enamel surface, and cut off the enamel part. The enamel was treated with 85% phosphoric acid aqueous solution for 30 seconds, and the remaining acid solution was washed away with deionized water, and then used.

[0026] Weigh 2.88g of hydroxyethylethylenediaminetriacetic acid (HEDTA) and 0.58g of KOH, add about 90mL of deionized water, and stir to dissolve. Add 2.44g Ca(NO 3 ) 2 4H 2 O and 0.84 g KH 2 PO 4 , adjusted the pH to 6.0 with KOH solution, and constant volume in a 100mL volumetric flask to obtain a HEDTA-Ca-P solution.

[0027] Weigh 5.65g KF·2H 2 O, 100mL volumetric flask was made to volume to obtain KF solution.

[0028] Measure 87 mL of the above-prepared HEDTA-Ca-P solution, place the enamel treated with 85% by mass aqueous phosphoric acid solution in it, an...

Abstract

The invention discloses a method for preparing a dental prosthetic material. The method comprises the following steps: 1) an enamel is soaked with a phosphoric acid solution or a blend solution of hydrogen peroxide and phosphoric acid for treatment; and 2) the enamel in the step 1) is laid in an HEDTA-Ca-P solution, and a fluorine ion solution is added into the HEDTA-Ca-P solution so that the enamel covered with the prosthetic material is obtained after the reaction. The method for preparing the dental prosthetic material is characterized in that the conditions are mild, the process is simple, the raw materials are cheap, the method has the clinical application value, the prior dental prosthetic material prepared is hopefully replaced by the dental prosthetic material prepared to repair dental caries or enamel damage caused by other dental diseases, and the dental prosthetic material can be also as taken as a pit and fissure sealant material used for preventing dental caries.

Description

technical field [0001] The present invention relates to a method for preparing a dental restorative material. Background technique [0002] Enamel is the outermost part of human teeth, with a thickness of 1 to 2 mm. As the hardest mineralized tissue in the vertebrate kingdom, enamel cuts and grinds food. However, due to natural wear, acid bacterial corrosion, aging and other reasons, dental caries or other enamel damage diseases are very common. Severe dental caries is not only enamel damage, but also affects health and reduces quality of life. Studies have shown that the bacteria in carious surfaces may reach various parts of the human body along with the blood circulation, thereby inducing various diseases such as heart disease, arteriosclerosis, diabetes, and pregnancy syndrome. [0003] The best way to prevent the development of dental caries is to treat early superficial caries when they appear. At present, the commonly used method for the treatment of early dental ...
