Aligner AI

A clinical platform that allows orthodontists to monitor clear aligner treatment remotely using patient smartphone camera photographs with sub-millimeter AI computer vision.

Technologies Used

Python PyTorch React WebGL 3D GCP Docker

The Brief

Orthodontic treatment with clear aligners requires frequent progress checks, leading to patient compliance fatigue and unnecessary physical chair time.

Aligner AI empowers dental clinics to monitor tooth alignment, track bite registration, and flag poorly seating aligners remotely from smartphone photos.

Challenges

Calibrating smartphone dental photographs with clinical precision under erratic home lighting and varied camera sensors:

Sub-millimeter tooth movement detection from uncalibrated phone lenses.
Automated guidance ensuring patients capture proper dental angles.
Interactive 3D model overlays in a responsive doctor dashboard.
HIPAA-compliant encrypted cloud image storage.

Our Approach

Trained deep convolutional neural networks (CNNs) capable of segmenting individual teeth and comparing movement against treatment simulation models.

STEP 01

Photogrammetric AI Model

Developed CNN models trained on thousands of clinical orthodontic scans to extract 3D bite orientation from 2D photos.

STEP 02

Patient Mobile Guide

Created an intuitive camera overlay that guides patients to capture ideal lighting, focal distance, and bite views.

STEP 03

Doctor 3D Timeline Dashboard

Engineered WebGL-accelerated 3D teeth model viewer highlighting treatment tracking deltas in real-time.

STEP 04

Automated Non-Fit Alerts

Built compliance algorithms that notify orthodontists when an aligner tray loses contact before tooth tracking is compromised.
