Abstract

The invention discloses a manufacturing method of a baked porcelain veneer. The manufacturing method comprises the following steps: cleaning a tray, and pouring a model; dividing the model by a separation mechanism, manufacturing an individual generation type, pouring a set model, duplicating an individual generation type silicone rubber impression, pouring a refractory material generation type, firing the refractory generation type at high temperature, and firing the refractory generation type enamel paste; stacking facing porcelain, and roasting the facing porcelain in a porcelain roasting furnace; and after shape finishing and glazing are completed, seding the manufactured baked porcelain veneer to a doctor to be used for being bonded to a patient. Through high-temperature firing fire-resistant molding, the strength is good, the plasticity is high, the fire resistance is high, and the manufacturing efficiency is greatly improved; the piled facing porcelain adopts porcelain powder ofa baked porcelain crown in dental crown repair, the color is attractive, the effect is more similar to that of natural teeth, the appearance requirement of a patient can be met, meanwhile, a baked porcelain patch manufactured through baking of a porcelain oven is small in thickness, good in strength and good in abrasion resistance and corrosion resistance, and the original tooth tissues can be reserved to the maximum extent.

Description

technical field [0001] The invention relates to the field of oral restoration, in particular to a method for manufacturing a porcelain veneer. Background technique [0002] Among the existing oral veneer restoration techniques, two types of veneers are commonly used: [0003] One is cast porcelain veneer, which mainly adopts cast porcelain material, which is molded at one time by die-casting technology; the main component of cast porcelain material is silicon dioxide, which has high light transmission; therefore, for tooth discoloration caused by pigmentation, severe tetracycline teeth , Dental fluorosis, discoloration of dead pulp teeth and other cases, the masking effect is not ideal, and it is difficult to meet the requirements of patients. [0004] The other is resin veneer. The main component of resin veneer material is resin. In the oral environment, the resin material is easy to age, has poor corrosion resistance and wear resistance, resulting in a short service life...
