SYSTEMS AND METHODS FOR LIBRARY-BASED TOOTH SELECTION IN DIGITAL DENTAL APPLIANCE DESIGN
Disclosed are systems and methods for selecting a tooth library for auto-designing a dental appliance. A method includes receiving, by a computer system, patient tooth data including a scan of the patient's teeth, identifying markers on the teeth in the patient tooth data, such as opposing tooth edges, determining teeth measurements based on the markers, such as determining a width between the opposing tooth edges, and selecting, from a static tooth library data store, a subset of tooth libraries based on the teeth measurements and based on: identifying at least one tooth library having respective tooth width measurements within a threshold range of the determined width of the tooth in the patient tooth data, and adding the identified at least one tooth library to the subset of tooth libraries. The method also includes selecting a candidate tooth library from the subset based on the candidate tooth library satisfying dental-appliance-fit criteria.

A method for generating a digital denture model can include receiving scans of dentures generated by a CT scan. The scans can include a bite scan showing the positioning of an upper and lower denture in a patient bite orientation. The bite scan can be used to position upper and lower denture scans in the patient bite orientation and a denture model can be generated from the upper and lower scans in the patient bite orientation. Irregularities in the denture model, such as voids and metallic inclusions, can be corrected to provide a smooth model surface. Color images of the dentures can be correlated with the denture model to provide a colored denture model. During the CT scan, prompts can be generated for displaying quality analysis information during scanning, recommendations for adjustments to equipment or orientation of the dentures, and steps for performing the scan.
