Impression screening method, manufacturing method of impression screening jig, and impression screening jig

Abstract

The invention discloses an impression screening method, a manufacturing method of an impression screening jig, and the impression screening jig. The impression screening method comprises the followingsteps: manufacturing abutment jigs with different heights and different diameters according to a screening test result of historical gypsum abutment models; performing pouring on the abutment jigs toobtain impression jigs to make the impression jigs have holes with different depths and diameters; scanning the impression jigs with a scanner so as to determine a maximum scanning depth of the scanner; manufacturing an impression screening jig with the corresponding length according to the maximum scanning depth of the scanner; and screening impressions with the impression screening jig. The impression screening jig is manufactured according to the maximum scanning depth of the scanner, and impressions capable of being scanned by the scanner is screened out through the impression screening jig, so that the success rate of impression scanning is improved, and the effect of impression scanning in large quantities is realized.

Description

technical field [0001] The invention relates to the technical field of orthodontic devices, in particular to an impression screening method, a manufacturing method of an impression screening jig and an impression 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 impression 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 during the impression scanning process, the positions that cannot be scanned clearly are mainly the small and deep positions o...

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 impression can be scanned clearly by the naked eye, which makes it impossible to realize large-scale scanning, design and print models.
