Automatic detection of tooth type and eruption status

Systems and methods for detecting an eruption status (e.g., tooth type and/or eruption status) of a target tooth are provided herein. Tooth of a patient may be scanned and/or segmented. Target teeth may be identified. Tooth features, principal component analysis (PCA) features, and/or other features may be extracted and compared to the above features of other teeth (e.g., those obtained by an automated machine learning system). The detector may identify and/or output an eruption state of the target tooth, such as whether the target tooth is a fully-erupted deciduous tooth, a partially-erupted/unerupted permanent tooth or a fully-erupted permanent tooth. 本文提供了用于检测目标牙齿的萌出状态(例如，牙齿类型和/或萌出状态)的系统和方法。可以对患者的牙齿进行扫描和/或分割。可以识别目标牙齿。可以提取牙齿特征、主成分分析(PCA)特征和/或其他特征，并将其与其他牙齿的上述特征(例如通过自动机器学习系统获得的那些特征)进行比较。检测器可以识别和/或输出目标牙齿的萌出状态，例如目标牙齿是完全萌出的乳牙、部分萌出/未萌出的恒牙还是完全萌出的恒牙。
