Problems solved by technology

[0004] In addition, the scannable boundary of the scanner can only be obtained through batch scanning tests. At the same time, it is also difficult to judge whether the undivided plaster can be scanned clearly by the naked eye, which makes it impossible to realize large-scale scanning design and undivided plaster models.

Abstract

The invention discloses a non-divided gypsum model screening method, a screening fixture manufacturing method and the screening fixture. The non-divided gypsum model screening method includes: making a gypsum model with different adjacent abutment teeth according to the screening test results of historical gypsum abutment models. The abutment jig with a plane angle; use the scanner to scan the abutment jig to determine the minimum scanning angle of the scanner; make an undivided plaster model of the corresponding angle for screening according to the minimum scanning angle of the scanner Fixture: use the undivided plaster model screening jig to screen the undivided plaster model. According to the minimum scanning angle of the scanner, the present invention makes an undivided gypsum model screening jig, and uses the undivided gypsum model screening jig to screen undivided plaster models that can be scanned by the scanner, thereby improving the success of undivided plaster model scanning The rate can achieve the effect of batch scanning without dividing the plaster model.

Description

technical field [0001] The invention relates to the technical field of orthodontic devices, in particular to a screening method for a non-divided plaster model, a manufacturing method for a screening jig and the screening jig. Background technique [0002] At present, the scanning principles and mechanical structures of commonly used dental scanners are different, and the depth angles that can be scanned when scanning the model are also different. For non-divided plaster model scanning, the traditional method generally uses various scanners to scan separately, resulting in long scanning time and unable to quickly and accurately select the items that can be successfully scanned. [0003] The scanning depth of the scanner is mainly related to the angle between the lens and the distance from the lens to the scanned part. During the small batch test, it was found that in the process of scanning without dividing the plaster, the position that cannot be scanned clearly is mainly a...
