STSR 2025 : 3rd Semi-supervised Teeth Segmentation and Registration MICCAI Challenge

📌 Introduction

Computer-aided diagnosis tools are increasingly popular in modern dental practice, particularly for treatment planning or comprehensive prognosis evaluation. With the advancement of oral digitalization and three-dimensional scanning technology, cone-beam computed tomography (CBCT) and intraoral scanning (IOS) have been widely applied in clinical dental treatment. Intraoral scanning (IOS) models offer high resolution, relying solely on IOS data for treatment carries the risk of insufficient root information. Conversely, CBCT provides comprehensive information on both crowns and roots, but its scanning resolution is lower, and it contains more redundant information. Therefore, combining the two can better utilize their complementary strengths, enhancing the precision and efficiency of dental treatment. Furthermore, automated and precise evaluation of root pulp canals in CBCT images holds significant importance, as it can substantially enhance the precision and efficiency of root pulp canals treatment. Precise segmentation of the root pulp canal allows for a clearer visualization of its morphology, branches, and curvatures, facilitating the development of more refined filling strategies. However, the annotation of tooth root pulp canal regions in CBCT images is inherently labor-intensive, requiring a substantial investment of time and human resources.

In this year, building upon the previous semi-supervised challenge theme, we hosttwo novel subtrasks, which are semi-supervised CBCT-IOS registration and CBCT teeth and root plup segmentation. We are proud to announce the launch of the challenge workshop. If you are interested in publishing a workshop paper, please 👉read the CfP and submit your paper :

Track 1: CBCT teeth and root plup canal segmentation

The segmentation algorithm is expected to segment all the teeth and root plup canal accurately.

Track 2: CBCT-IOS registration

The registration algorithm is expected to register the teeth crown and the corresponding root.
