This paper presents a comprehensive study on the application of Augmented Reality (AR) and Virtual Reality (VR) in the dental field, integrating advanced computational techniques such as Convolutional Neural Networks (CNNs) for precise image segmentation and the Marching Cubes algorithm for high-resolution 3D reconstruction. The proposed system significantly improves dental education, diagnostic procedures, and treatment planning by creating immersive and interactive environments. CNNs are utilized to enhance the accuracy of dental image analysis, while the Marching Cubes algorithm enables the generation of detailed, realistic 3D models of oral anatomy. This dual approach addresses key limitations in traditional dental training and clinical workflows, fostering a deeper understanding of anatomical structures and increasing the efficiency of diagnosis and treatment. Experimental evaluations reveal substantial improvements in segmentation accuracy and user engagement, demonstrating the system\'s potential to revolutionize both academic and clinical practices in modern dentistry through AR/VR integration.
Introduction
The dental industry is undergoing a significant transformation with the integration of Augmented Reality (AR), Virtual Reality (VR), and AI-driven technologies. These immersive tools enhance clinical diagnostics, treatment planning, and dental education by providing interactive, 3D environments. Key technologies include Convolutional Neural Networks (CNNs) for accurate segmentation of dental structures from radiographs and the Marching Cubes algorithm for converting segmented data into high-fidelity 3D models.
In education, these technologies offer realistic simulations, improving student engagement and skill acquisition. Clinically, they support more accurate diagnoses and personalized treatment by enabling detailed anatomical visualization and real-time surgical guidance.
The literature supports these advances, showing success in applications like VR-based simulators and AR-guided surgeries. However, challenges such as manual segmentation, latency, registration errors, and lack of real-time model updates persist in existing systems.
To address these, the proposed system fully automates the process:
Marching Cubes reconstructs the data into 3D models.
These models are used in AR (e.g., Microsoft HoloLens) and VR (e.g., Oculus Rift) platforms for clinical and educational use.
Benefits include:
Real-time, patient-specific 3D visualization.
Improved diagnostic accuracy and surgical planning.
Enhanced student learning through immersive simulation.
The system also responds to the global burden of oral diseases, which affect 3.5 billion people. Conditions like dental caries, periodontal disease, and oral cancers are often linked to socioeconomic disparities and poor access to care. AR/VR combined with AI can support early diagnosis, personalized treatment, and broader access to quality dental training—especially in underserved regions.
