3D Dental Scan Matching System for Prosthodontic Applications

JashDS developed a comprehensive dental scan matching system leveraging cloud infrastructure, advanced 3D processing algorithms, and vector-based similarity search. The solution was designed to be fully automated, scalable, and accessible through standardized APIs.

Key components of the solution included:

• AWS-Based Architecture: The system implemented an AWS infrastructure utilizing EC2 for computational processing, S3 buckets for secure storage of dental scans, and ChromaDB for high-performance vector storage and retrieval.
• Automated STL File Processing Pipeline: A robust pipeline was created to process dental scan files with several critical steps:
• Input validation to ensure system reliability and consistency
• Orientation correction to automatically standardize arbitrarily aligned scans
• Slice generation at specified heights to capture features at different levels of dental structure
• Feature extraction using PCA-based orientation checks and generating 512D vectors
• Database operations storing vector embeddings in ChromaDB with relevant metadata
• Cron-Driven Automation: An intelligent system was implemented with configuration initialization, file discovery, secure processing, vector generation, and state synchronization to ensure continuous updates as new scans were uploaded.
• Dual API Implementation: The solution delivered two primary APIs:
• Query S3 Files API allowing searches against the entire database of processed scans
• Query Local Files API enabling users to upload and match new files against the database

The system's design prioritized cost efficiency, technical advantages through dental-specific geometric features, operational simplicity, and business benefits including lower total cost of ownership compared to deep learning alternatives.
