Intelligent scanning for intraoral scanners

A method of intraoral scanning includes receiving one or more first intraoral scans of a patient's oral cavity; automatically determining a first scan character associated with the one or more first intraoral scans based on processing of the one or more first intraoral scans, where the first scan character is a first one of an upper arch character, a lower arch character, or an occlusal character; and determining a first three-dimensional surface associated with the first scanned character. 一种口内扫描的方法，包括接收患者口腔的一个或多个第一口内扫描；基于一个或多个第一口内扫描的处理，自动确定与一个或多个第一口内扫描相关联的第一扫描角色，其中，第一扫描角色是上牙弓角色、下牙弓角色或咬合角色中的第一个；以及确定与第一扫描角色相关联的第一三维表面。
