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 from tooth preparation and a preparation method of the skeleton porcelain tooth veneer. The method includes the steps of impression; scanning;designing; numerical-control equipment processing to cut out a wax shape of dentin form; embedding to form a hollow model of the dentin form; casting, namely putting porcelain into the hollow model for casting so that a skeleton porcelain with the dentin form is formed after casting; applying of veneering porcelain, namely mixing porcelain powder with special liquid in paste and coating the sameto the skeleton porcelain to form a veneer shape to ensure that the thickness is consistent with designed thickness, and performing sintering and drying; grinding, namely performing dyeing and glazingto obtain the finished product. The tooth veneer is made of the skeleton porcelain and the veneer porcelain by splicing processing, so that the thickness is further reduced, and the thinnest part canreach the thickness of 0.2mm; the thickness of the veneer is reduced, the removal of teeth is small, and tooth damage is reduced; the skeleton porcelain is made of cast porcelain, the veneer porcelain is made of porcelain, and high strength of the cast porcelain and color and simulation of the porcelain are combined; adopting the dentin form, the skeleton porcelain 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...
