Preparation method of aesthetic all-zirconia restoration body

Abstract

The invention relates to a preparation method of an aesthetic all-zirconia restoration body. The process comprises the steps of: clinically making an impression and a model after tooth preparation, collecting the digital impression, establishing a digital model, designing the shape of the restoration body by being assisted with a computer, cutting into the shape of the restoration body by a digital control lathe, try-wearing on the model, adjusting the outline form, polishing, coloring, glazing, and completing the fabrication of final restoration body. The restoration body is colored by using a coloring zirconia porcelain piece; the coloring process is influenced little by personal factors; an all-zirconium-crown cutting end transparent handling liquid is used to handle the presintered tooth crown, so that the color and the transparence of the zirconia all-porcelain tooth change gradually, so that an ideal aesthetic effect is achieved. The preparation process is free of porcelain coating. The method has no porcelain fracture danger, and the operation is simple. The prepared tooth is few, so 1mm of preparation space is enough to use. The zirconia all-porcelain tooth has excellent biocompatibility, high strength, good transparence and glossiness, and natural and lifelike colors. CAD / CAM (Computer-Aided Design / computer-aided manufacturing) is used for designing and completing the processing, thereby ensuring the marginal adaption and precision of the zirconia all-crown porcelain tooth.

Description

technical field

[0001] The invention belongs to the technical field of oral ceramic materials and preparation thereof, and in particular relates to a preparation method of an aesthetic full zirconia restoration. Background technique

[0002] In recent years, more and more patients and physicians choose all-ceramic materials as permanent restorations in the oral cavity. All-ceramic materials have incomparable advantages over metal, it will not stain the gums, will not have the problem of metal base exposure, there is no corrosion in the mouth, no metal to block the light, and can realistically reproduce the color and translucency of natural teeth. It is the restoration with the best aesthetic effect, and is highly praised by successful people and people in the entertainment industry. In addition, patients need to do cranial X-ray, CT, and MRI examination rooms and do not need to remove dentures. At the same time, all-ceramic materials have good biocompatibility, no irritatio...
