Embodiment Construction

[0043] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0044] Intraoral 3D scanners are widely used in the field of fixed oral restorations, and their applications in the field of oral active restorations and implant restorations are also developing rapidly. Scanning accuracy is a key indicator to measure the clinical suitability of an intraoral 3D scanning system.

[0045] The inventors of the present invention found in research that for single-tooth restorations, three-unit fix...

Abstract

The invention discloses an auxiliary device, an auxiliary device assembly and an intraoral three-dimensional graph acquisition method. The auxiliary device is used for assisting an intraoral three-dimensional scanner to acquire an intraoral three-dimensional graph and comprises a connecting part, a feature part and a feature pattern, wherein the connecting part can be mounted on a fixed body; the feature part is connected to the connecting part and is of a sheet-shaped structure; the feature pattern is arranged on the feature part; and when the connecting part is mounted on the fixed body, the feature part is vertically or obliquely arranged relative to an alveolar ridge, so that a mucous membrane of the alveolar ridge can be exposed. According to the auxiliary device disclosed by the embodiments of the invention, the feature part is provided with the feature pattern, the mucous membrane of the alveolar ridge is exposed, and when the intraoral three-dimensional scanner is used for carrying out scanning, accurate spatial position relationships of multiple tooth positions and information on mucous membranes of the alveolar ridges can be obtained through one-time scanning, so that the scanning precision is improved, and the scanning efficiency is also increased.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional scanning, in particular to an auxiliary device, an auxiliary device component and a method for acquiring three-dimensional graphics in the mouth. Background technique [0002] At present, intraoral 3D scanners are mostly used in single-tooth restorations, three-unit fixed bridges, and upper restorations of single-tooth implants, and their scanning accuracy can meet clinical requirements. However, for restorations with a large span such as multi-teeth fixed restorations, multi-tooth implant restorations, and movable restorations with more than three units, the scanning accuracy is still insufficient. Contents of the invention [0003] The invention provides an auxiliary device capable of improving the scanning accuracy of multiple tooth positions, an auxiliary device component and a method for acquiring three-dimensional graphics in the mouth. [0004] The auxiliary device acco...
