Summary

This study tests whether artificial intelligence (AI) can design dental crowns as well as a human technician. Forty adults with a damaged back tooth will receive either an AI-designed crown or a standard computer-designed one. Researchers will check for cracks, loosening, and overall performance over time to see if the AI method is a reliable option.
