This study presents a robust dental arch curve optimization method for panoramic image reconstruction from CBCT images. The proposed approach integrates prior maxillofacial anatomical knowledge through a statistical standard arch form and introduces an assessment function to guide the fitting of anatomically accurate and convex dental arch curves. Experimental validation in clinically diverse CBCT datasets demonstrates the effectiveness of the method in challenging scenarios, including orthodontic appliances, rigid internal fixation, mixed dentition, complete edentulism, and impacted teeth. The results confirm that the proposed method enables high-quality panoramic image reconstruction suitable for various dental imaging applications.

摘要

This study presents a robust dental arch curve optimization method for panoramic image reconstruction from CBCT images. The proposed approach integrates prior maxillofacial anatomical knowledge through a statistical standard arch form and introduces an assessment function to guide the fitting of anatomically accurate and convex dental arch curves. Experimental validation in clinically diverse CBCT datasets demonstrates the effectiveness of the method in challenging scenarios, including orthodontic appliances, rigid internal fixation, mixed dentition, complete edentulism, and impacted teeth. The results confirm that the proposed method enables high-quality panoramic image reconstruction suitable for various dental imaging applications.
