Document Type and Number:
WIPO Patent Application WO/2023/279905
Kind Code:
A1
Abstract:
An auxiliary device (1), an auxiliary device (1) assembly, and a method for acquiring an intraoral three-dimensional drawing. The auxiliary device (1) is used to assist an intraoral three-dimensional scanner to acquire an intraoral three-dimensional drawing, and comprises: a connecting portion (100), a feature portion (200) and a feature pattern (300), wherein the connecting portion (100) can be mounted on a fixing body; the feature portion (200) is connected to the connecting portion (100) and has a sheet-shaped structure; the feature pattern (300) is arranged on the feature portion (200); and when the connecting portion (100) is mounted on the fixing body, the feature portion (200) is vertically or obliquely arranged relative to an alveolar ridge, such that an alveolar ridge mucosa is exposed. The feature portion (200) of the auxiliary device (1) is provided with the feature pattern (300), and the alveolar ridge mucosa is exposed, such that when the intraoral three-dimensional scanner is used to perform scanning, an accurate spatial position relationship of multiple tooth positions and information of the alveolar ridge mucosa can be acquired by scanning once, which not only improves the scanning precision, but also improves the scanning efficiency.
