Problems solved by technology

To repair the above-mentioned damaged tooth shape, the existing dental technology usually adopts the method of bonding repair materials on the damaged position of the damaged tooth shape, and then repairs it by grinding. The workload is heavy, and the quality of the tooth-shaped crown after restoration is completely determined by the dentist's personal technical level. The shape of the tooth-shaped crown is difficult to achieve the general tooth-shaped crown shape of human teeth, which makes the patient feel uncomfortable after the tooth is repaired.

Embodiment 1

[0025] The braces processing method of the present invention acquires and processes braces processing data through a control computer of the processing system and a scanning device connected to the control computer, and uses the braces processing data to control a braces processing machine tool to process braces.

[0026] like figure 1 Shown, braces processing method of the present invention comprises the steps:

[0027] Step 1, install the dental model (made by the dentist according to the patient's diseased teeth) that needs to be prepared on the machine tool processing table, start the scanning device to scan the dental model, and compare the scanned dental model's shape to the three-dimensional scanning base point. The coordinate data is sent to the control computer, and the control computer reads the tooth shape template data corresponding to the dental model in the database. The scanning base point is the reference point of the scanning device. The scanning device estab...

Embodiment 2

[0034] This embodiment is basically the same as Embodiment 1, the difference is: in step 3 of this embodiment, no operator is set to manually modify the brace model. That is, the control computer uses the existing 3D imaging technology to perform three-dimensional modeling of the braces based on the scanned data of the dental model and the data of the braces to correct the outer crowns. After obtaining the braces model including the inner and outer crowns, it proceeds to step 4 to complete the generation of processing data.

[0035] In the above embodiments, the dental model can be a single tooth model, or a dental model with more than two teeth. When the dental model is a dental model with more than two teeth, the tooth shape template data in step 1 includes the corresponding braces model data and the corresponding dental bridge data (the database includes each tooth connected to two adjacent teeth in each position of the human oral cavity respectively). Bridge data, the brid...

Abstract

The invention relates to a method for processing teeth braces. Three dimensional coordinate data of a tooth model are scanned by a scanning device in a scanning and processing worktable and are transmitted to a control computer for reading corresponded data of a tooth shape template; initial external crowns of the teeth braces are formed according to the scanning data and a forming principle of the initial external crowns of the teeth braces; the coordinate data of the initial crowns of the teeth braces and the data of the initial external crowns of the tooth shape template are scanned for a differential value operation to obtain the data of amended external crowns of the teeth braces; a three-dimensional modeling is carried out according to the scanning data of the tooth model and data of the amended external crown of the teeth braces; then the models of the teeth braces are obtained; an automatic trimming of materials other than the external crowns is carried out; direction and brightness of a light projection are set; the tooth model on the processing worktable is scanned for the differential value operation with the data of the models of the teeth braces so as to obtain point-by-point processing data of the teeth braces and send a processing order to a processing machine to process the teeth braces. The method has the advantages that: the teeth braces with external crowns almost close to a natural tooth shape can be obtained and the amendment of the external crowns of the teeth braces is convenient; internal crowns of the teeth braes closely are matched with the shape of teeth; dental treatment level is enhanced.

Description

technical field [0001] The present invention relates to a kind of processing method, more specifically, relate to a kind of braces processing method. Background technique [0002] Among the tooth shape damages, tooth tooth shape damage caused by dental diseases such as dental caries and caries, or tooth tooth shape damage caused by physical reasons are the most common. To repair the above-mentioned damaged tooth shape, the existing dental technology usually adopts the method of bonding repair materials on the damaged position of the damaged tooth shape, and then repairs it by grinding. The workload is heavy, and the quality of the repaired tooth-shaped crown is entirely determined by the dentist's personal technical level. The shape of the tooth-shaped crown is difficult to reach the general tooth-shaped crown shape of human teeth, which makes the patient feel uncomfortable after the tooth is repaired. Contents of the invention [0003] The technical problem to be solved ...
