Problems solved by technology

[0003] When the existing denture virtual model is typesetting and designing in the computer, a single denture is typesetting separately, that is, each crown or bridge is an independent restoration, and each independent restoration must have an independent The tool path is used for the placement of the support rod and the passage of the tool, which wastes a lot of space. Although this typesetting method can freely allocate high and low ceramic blocks for fast tooth row cutting, the cutting time is relatively long, and the ceramic blocks are made of large materials. Porcelain blocks are relatively expensive materials, which is not conducive to cost savings

Embodiment Construction

[0022] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0023] The processing method of the novel typesetting of zirconia denture proposed by an embodiment of the present invention comprises the following steps:

[0024] 1) Scanning, use a 3D scanner to scan the upper and lower dentition, missing position, gums and occlusal relationship in the patient's mouth and obtain corresponding data, and store the scanned data in the computer to form a virtual three-dimensional crown or bridge Or, use the existing technology to make the plaster dental model of the patient, use an optical scanner to scan the shape and size of the plaster model, collect the three-dimensional data of the optical impression of the plaster dental model, and store the scanned data in the computer to form a virtual crown Or a 3D model of a dental bridge.

[0025] 2) Design, use computer ...

Abstract

The invention discloses a novel typesetting processing method for zirconium oxide false teeth. The processing method comprises the following steps: 1) performing scanning: performing three-dimensionalscanning on teeth of a patient and transmitting the obtained three-dimensional data to a computer; (2) performing designing and typesetting: editing the three-dimensional data in the step (1) by utilizing computer design software, designing a dental crown or dental bridge suitable for patient ergonomics, and obtaining stl data; (3) creating an integral restoration body, importing the stl data inthe step (2) into the magic software, and creating a connecting body among a plurality of dental crowns or dental bridges, so that the dental crowns or the dental bridges are connected with one another to form the integral restoration body; 4) performing processing; and 5) performing sintering. According to the invention, the arrangement of the dental crowns or the dental bridges is more compact,the processing gap is reduced, and more teeth can be obtained by cutting the same material, so that the expensive zirconium dioxide material is saved.

Description

technical field [0001] The invention relates to the technical field of dental restoration, in particular to a processing method for a new layout of zirconia dentures. Background technique [0002] Dentures are artificial teeth that replace missing natural teeth, also known as dentures. Severe periodontal disease, dental caries and trauma can cause partial or even complete loss of dentition. Loss of teeth can affect facial features, pronunciation, and chewing functions, and increase the burden on the stomach If it is not repaired in time, the adjacent teeth will be tilted and shifted, and the opposing teeth will be elongated, causing the occlusion to be disordered. Part of the missing dentition can be repaired with fixed or removable dentures, or with complete dentures if there are no teeth. Zirconia porcelain block is an important raw material for the production of dentures, that is, the porcelain block can be carved into dentures by an engraving machine. [0003] When the...
