OralViewer: 3D Demonstration of Dental Surgeries for Patient Education with Oral Cavity Reconstruction from a 2D Panoramic X-ray

Abstract

Figure 1: Overview of OralViewer. The system takes a patient's 2D X-ray as input (a), and reconstructs the 3D teeth structure (b) with a novel deep learning model. The system then generates the complete oral cavity model (c) by registering the pre-defined models of jaw bone and gum to the dental arch curve. Finally, a dentist can demonstrate the forthcoming surgeries to a patient by animating the steps with our virtual dental instruments (d).

CBCT-guided 3D Dental Structure Reconstruction from Panoramic X-ray: A Preprocessing Pipeline

“…To address these limitations, there have been a few studies on reconstructing the 3D dental structure from a 2D panoramic X-ray image without requiring any additional scans [3,4,5]. It consists of two major steps: (1) generating a flattened 3D volume from a panoramic X-ray, and (2) registering the flattened 3D volume to a dental arch curve.…”
