Embodiment Construction

[0027] A method for fully digitizing zirconia all-ceramic veneers to repair dental crowns and bridges, comprising the following steps:

[0028] S1: Scan the inside of the patient's oral cavity. The intraoral scanner adopts a dual-lens type, which can scan twice at the same time. The scanned data automatically synthesizes an image. When the synthesized image of the two scanned data is inconsistent, the system will automatically perform a second scan. The scanning will not be stopped until the scanning data of the two lenses are consistent, and the three-dimensional model data of the dental crown in the patient's mouth will be obtained;

[0029] S2: Carry out three-dimensional reconstruction intraoral model according to three-dimensional model data;

[0030] S3: Data analysis of the shape of the collapsed porcelain part in the cavity, the shape of the surrounding natural teeth, the shape of the soft tissue in the mouth, the occlusion in the mouth, and the smile line;

[0031] S...

Abstract

The invention relates to a method for repairing fractured ceramic on dental crowns and bridges by using completely-digitized zirconia all-ceramic veneer. The method comprises the following steps: intraoral scanning, three-dimensional reconstruction of an intraoral model, data analysis, veneer designing and 3D printing, and intraoral bonding. The method provided by the invention can realize individualized repairing of ceramic-fractured parts, is non-traumatic, rapid and simple, saves time and cost.

Description

technical field [0001] The invention relates to the technical field of dental restoration, and more particularly, relates to a method for repairing chipped porcelain of a tooth crown and bridge with a completely digital zirconia all-ceramic veneer. Background technique [0002] At present, the custom method of tooth crown and bridge crumbling porcelain is mainly to bond the crumbling porcelain part through light curing, or directly use light curing resin to fill it, or even remove the crown and redo it. When this method is used to restore the broken porcelain of the dental crown and bridge, on the one hand, it will cause certain damage to the patient's oral cavity; , and at the same time there is a problem that the repair time is too long, which brings a bad repair experience to the patient. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a method for completely digitalized zirconia all-...
