Abstract

The invention provides a fabricating method of an all-ceramic preformed crown basic set. The fabricating method comprises the following steps: (1) designing the size of the all-ceramic preformed crownset according to the collected tooth size data, wherein the thickness of the all-ceramic preformed crown is 4-6 mm, and carrying out computer typesetting; (2) selecting zirconium oxide, and carryingout cutting to form a zirconium oxide crown; (3) carrying out coloring in a coloring agent; (4) carrying out sintering in a sintering furnace; (5) carrying out grinding for trimming; (6) carrying outglazing on the outer part of the crown, and carrying out sintering; and (7) carrying out quality testing and delivery. For the fabricating method of the all-ceramic preformed crown basic set, the zirconium oxide crown with the excellent biocompatibility, aesthetic degree and safety is adopted, thus the quality stability of the preformed crown is guaranteed, the problems of mixing ratio error of the raw materials and the coloring agent and the incomplete forming during the injection moulding process are avoided, due to the high precision of a five-axis linkage device, the delivery qualificationrate of the product is guaranteed, the production and fabrication procedures are reduced, thus the labor cost is reduced, and meanwhile, the batch production can be accelerated.

Description

technical field [0001] The invention belongs to the technical field of oral restoration, and in particular relates to a manufacturing method of an all-ceramic prefabricated crown base set. Background technique [0002] Dental diseases such as dental caries or pulpitis are common cases in oral diagnosis and treatment. The treatment of dental caries generally adopts filling treatment, and materials such as resin or glass ion are often used to restore the shape of the tooth. Pulpitis needs to be treated after root canal treatment. Restoring the shape of the tooth through filling treatment. After dental treatment, the affected teeth often have defects such as poor retention of fillings, easy to fall off, increased brittleness of the tooth, and easy fracture. Therefore, follow-up permanent restoration treatment, such as casting crowns or porcelain crowns, is required. Similar dental treatment is also used for caries and pulpitis of children's deciduous teeth. Since children's de...
