Automatic detection of tooth type and eruption status

Abstract

Provided herein are systems and methods for detecting the eruption state (e.g., tooth type and / or eruption status) of a target tooth. A patient's dentition may be scanned and / or segmented. A target tooth may be identified. Dental features, principal component analysis (PCA) features, and / or other features may be extracted and compared to those of other teeth, such as those obtained through automated machine learning systems. A detector can identify and / or output the eruption state of the target tooth, such as whether the target tooth is a fully erupted primary tooth, a permanent partially erupted / un-erupted tooth, or a fully erupted permanent tooth.

Background technique [0005] In pediatric cases, orthodontic appliances are often used before all of the patient's permanent teeth have erupted. Detecting erupting teeth can help prevent aligners from striking or contacting erupting teeth, which could stop the eruption of the teeth or injure the patient.

Problems solved by technology

This may require a physical examination of the tooth or images / scans of the teeth, and a medical professional's judgment on eruption status and tooth type, which adds time and expense
