Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Such as Figure 1-4 shown.

[0033] A method for preparing zirconia all-ceramic posts / nails for dental restoration, comprising the following steps:

[0034] First, collect the size parameters of the pile / nail required for the repaired part;

[0035] Secondly, according to the collected size parameters, make corresponding piles and nail wax rod plaster models;

[0036] Third, input the data of the plaster model into the CAD / CAM database;

[0037] Fourth, use CAD / CAM technology to control mechanical processing equipment to cut and process zirconia ceramic blocks of the desired shape. During the cutting process, the shrinkage rate (generally 20%) during the sintering process of the zirconia ceramic block should be taken into account. The corresponding size is correspondingly enlarged (enlarged to 125% of the actual size);

[0038] Fifth, put th...

Abstract

A preparation method of a zirconium dioxide all-ceramic post / pin for dental restoration is characterized by comprising the following steps: firstly, acquiring the size parameters of a post / pin required by a restoration part; secondly, manufacturing a corresponding post / pin wax rod plaster model according to the acquired size parameters; thirdly, inputting data of the plaster model into a CAD / CAM database; fourthly, utilizing the CAD / CAM technology to control machining equipment to cut and process a zirconium dioxide ceramic block of the required shape, wherein the corresponding sizes have to be amplified correspondingly under the consideration of the shrinkage ratio of the zirconium dioxide ceramic block in the sintering process during cutting; fifthly, placing the cut zirconium dioxide post / pin into a zirconium dioxide sintering furnace for sintering forming; sixthly, performing sand-blasting and cleaning treatment on the surface of the zirconium dioxide post / pin subjected to sintering forming; and seventhly, before use, performing surface pretreatment on the zirconium dioxide post / pin subjected to sand-blasting and cleaning treatment for later use. The preparation method provides a high-strength corrosion-resistant durable material for dental restoration, which is convenient to manufacture and use and is an ideal novel material for the dental department.

Description

technical field [0001] The invention relates to a method for preparing medical equipment, in particular to a method for preparing a raw material for dental restoration, in particular to a method for preparing a zirconia all-ceramic post / nail for dental restoration. Background technique [0002] Due to dental caries or trauma caused by a large area of ​​tooth defect, due to the weak remaining tooth tissue, fillings are easily broken or fall off. The most commonly used clinical solution is to use metal nails or fiber posts to enhance the retention. The metal nail body is easily corroded by liquids such as saliva in the oral cavity and dentinal tubule fluid, which in turn causes discoloration of the tooth and restoration and loosening of the retaining screw, resulting in restoration failure. The strength of the fiber post is poor, the bonding effect with the tooth tissue and resin material is not clear, and it is easy to break, and the end of the fiber post is cylindrical, and...
