Embodiment Construction

[0031] The present invention provides a skeleton porcelain veneer free from tooth preparation and a preparation method thereof. The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Such as figure 1 and figure 2 Shown, a kind of preparation method that is exempted from the skeleton porcelain veneer of tooth preparation provided by the invention, comprises the following steps:

[0033] The impression, using impression glue, forms a solid dental model after the patient occludes;

[0034] Scanning, using a 3D scanner to scan the dental model to form a 3D stereoscopic image, and design a veneer below 0.5mm on the virtual 3D stereoscopic image; the scanning image is closer to the real situation, the simulation effect is realistic, and the accuracy is higher;

[0035] Design, judge the thickness of the dental veneer according to the patient's three-dimensional image and the anatomical ra...

Abstract

The invention discloses a skeleton porcelain tooth veneer free from tooth preparation and a preparation method thereof. The method comprises the following steps: stamping, scanning, designing, processing and cutting with numerical control equipment to produce a wax pattern of the dentin shape; embedding to form the dentin The hollow model of the shape; casting, put the cast porcelain into the hollow model for die-casting, and form the skeleton porcelain in the form of dentin after die-casting; the top facing porcelain, mix the porcelain powder and the special liquid to form a paste, and coat it on the skeleton porcelain Form the shape of the veneer, ensure that the thickness is consistent with the designed thickness, sinter and dry, polish, dye and glaze, and obtain the finished product. In the present invention, the dental veneer is processed by splicing two kinds of skeleton porcelain and veneer porcelain, and the thickness is further reduced, and the thinnest can reach 0.2mm; the thickness becomes thinner, the tooth grinding amount is small, and the tooth damage is reduced; the skeleton porcelain adopts Made of cast porcelain, the veneer porcelain is made of porcelain, which combines the high strength of cast porcelain with the color and imitation of porcelain; the skeleton porcelain adopts the shape of dentin, which is not easy to crack or break, and has strong stability.

Description

technical field [0001] The invention relates to the technical field of tooth restoration, in particular to a skeleton porcelain veneer without tooth preparation and a preparation method thereof. Background technique [0002] Dental veneers have excellent aesthetic improvement effects on dental problems such as dental fluorosis, mild to moderate tetracycline teeth, and slight misalignment of teeth, and cause minimal damage to patients' teeth, so more and more people choose veneers for restoration teeth. Dental veneer is a technology of tooth whitening and restoration. Restoration is to paste a layer of material similar to normal tooth color on the surface of stained teeth to cover the color on the teeth. [0003] The existing porcelain veneer technology has a production thickness of more than 0.78mm due to the manual operation of the wax pattern, the strength of the material and the preparation technology. If the thickness of veneer porcelain and cast porcelain is completel...
