Description
Technical Field
The invention relates to the technical field of tooth veneers, in particular to a manufacturing method of a disposable ultrathin tooth veneer.
Background
The unaesthetic appearance of human teeth mainly includes dentition irregularities, tooth morphological defect deformities, tooth color abnormalities, and the like. Existing techniques for cosmetic application to teeth mainly include orthodontic, tooth bleaching and adhesive tooth veneering. Wherein the adhesive type tooth veneer is formed by bonding a ceramic or resin material sheet with proper color on the tooth surface in a permanent manner by using an adhesive so as to change the tooth shape, arrangement and color.
The above facing cosmetic tooth technique has the following problems:
a layer of artificial material is required to be permanently adhered to the teeth, and part of patients have obvious foreign body sensation, and improper treatment can influence the oral cavity movement energy of chewing and pronunciation;
in order to ensure the strength of long-term use, the permanent veneers usually need to reach a certain thickness, and in order to avoid the visual appearance of 'bucktooth' after veneers are bonded, the surfaces of the natural teeth are usually required to be ground to be equal in thickness, so that the natural teeth are damaged, and meanwhile, uncomfortable symptoms such as pain of patients are caused;
after the existing veneers are adhered to the tooth surfaces, if the shape and the color of a patient are not satisfied, or the aesthetic appeal of the patient changes along with changes of age, environment, application scene and the like, the direct change in the oral cavity is difficult, and the traditional veneers are usually required to be manufactured again after being manually removed by a special tool by a professional dentist, so that time and labor are wasted;
some patients need to make teeth beauty not permanently, but only intermittently in special scenes, and when the patients are separated from the scenes, the patients still want to restore to the original 'no-veneered' state, and although the resin temporary veneers clinically manufactured for the patients exist at present, the temporary veneers manufactured by the existing temporary veneers technology need to be worn and removed by special doctors, and the patients cannot wear and completely remove the resin temporary veneers by themselves.
In conclusion, the technical field of tooth cosmetology lacks a temporary manufacturing method of a tooth aesthetic veneer which can be taken off and worn and has extremely thin thickness, so that the characteristics of easy taking off and wearing at any time, simple replacement and no damage to natural teeth are realized.
