All-ceramic whitening tooth socket and preparation method thereof

Abstract

The invention relates to an all-ceramic whitening tooth socket and a preparation method thereof. The preparation method comprises the following steps: scanning the oral cavity of a patient through a scanner to obtain a digital model of the whole dentition of the patient; inputting the digital model into computer-aided design software, determining a tooth position to be manufactured based on the tooth socket requirement of the patient, determining an outer crown mode, adding a connecting body, selecting a digital impression and a jaw tooth in the computer-aided design software based on the tooth position to be manufactured, and further obtaining an order corresponding to the tooth position; respectively determining the direction of an insertion path and drawing an edge line contour based on the dentition condition and the undercut filling condition of a patient, selecting digital tooth forms in a tooth form database, then connecting each independent digital tooth form in a digital model into a whole, and obtaining tooth socket data; and performing secondary processing on the tooth socket data to obtain tooth socket model data, and performing printing based on the tooth socket model data to generate the all-ceramic whitening tooth socket; Healthy teeth do not need to be polished, the teeth are not affected, and existing tedious tooth whitening steps are simplified.

Description

technical field [0001] The invention relates to the field of braces equipment, in particular to an all-ceramic whitening brace and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's pursuit of beauty is increasing, especially in the management of the face, especially the teeth. As we age, the enamel of our teeth inevitably thins, causing more of the dentin color to show through, making teeth appear yellower. In addition, the food and dark drinks, smoking and drinking that people usually eat can also adhere to the enamel on the surface of the teeth, "coloring" the teeth, and with age, the teeth can only become more and more yellow. [0003] And the existing teeth whitening is divided into two categories: chemical whitening and physical whitening; among them, in physical whitening methods, such as resin, all-ceramic veneer and medical beauty porcelain teeth themselves belong to special medical methods, and t...

Problems solved by technology

[0005] When using the above-mentioned teeth whitening method, cold light whitening generally only lasts for 1-2 years, and if it is necessary to increase the degree of whitening, multiple treatments are required, and the higher the frequency of treatment, the degree of damage to tooth enamel and gums The bigger it is, the excessive and improper use of cold light whitening methods may even lead to premature aging and yellowing of teeth, and cold light whitening requires special instruments and medicines, and needs to be treated in a hospital; while the whitening of resin and all-ceramic veneers The method is expensive, requires grinding of the teeth, and is not suitable for abnormal shapes of teeth. At the same time, due to the thin thickness of resin and all-ceramic veneers, it is also very prone to collapse problems; Grinding teeth, and calculating the price of a single tooth, makes the price extremely expensive, and a little carelessness can easily cause a series of subsequent dental problems, such as gingivitis, tooth necrosis, pulpitis, etc., which will cause endless troubles; in addition, There is also a way of whitening tooth strips in teeth whitening, but tooth strips are not tailored for every user. The shape of tooth strips is similar to a transparent tape, and its size is not suitable for everyone's tooth shape. The stickers may come into contact with the gums and cause damage to the gum tissue

[0006] To sum up, the physical whitening methods in the current tooth whitening generally need to grind and process the patient's own teeth, which affects the tissue structure of the teeth themselves, while chemical whitening is likely to cause premature aging and yellowing of the teeth after repeated use, and further damage the teeth. Unfavorable in itself; and the steps of both physical whitening and chemical whitening are relatively cumbersome
