AI Smile Design Platform Build

I am developing an AI-powered dental smile-design platform that lets a dentist upload nothing more than a patient’s face and smile photos, then see an instant, photorealistic simulation of the ideal result. Core workflow • Upload face and intra-oral photos. • The system detects lips, teeth and gingiva, then generates a baseline smile proposal with computer-vision / GAN techniques. • The dentist can interactively refine that proposal by adjusting: – tooth shape, size and colour, – tooth position and the visible gum line, – restorative options such as veneers, zirconia crowns, bridges and implant-supported teeth. • Once the dentist and patient are satisfied, the dentist records the patient’s approval directly inside the software; that stored consent triggers export packages for the lab (high-res images, STL/OBJ if generated, and a treatment summary PDF). What I need from you 1. A full technical architecture (front-end, back-end, AI model pipeline and secure storage). 2. A sprint-level development task list that breaks the build into clear milestones, each with acceptance criteria. 3. Recommendations on proven open-source or commercial AI libraries suited to realistic dental morphing, plus any data-set requirements. 4. Wireframes or low-fi mock-ups showing the photo upload screen, the live editing canvas with layered controls, and the approval/export page. 5. A concise risk and compliance note (privacy, HIPAA/GDPR, data retention). Please ground every suggestion in practical, production-ready tech (e.g., Python, PyTorch, TensorFlow, React, Next.js, or comparable stacks you prefer). If you already have experience with dental CAD/CAM, DICOM, or photogrammetry, make that clear—those insights will accelerate the first release significantly.
