Which denture teeth last longest? new study puts 3D-Printed to the test
NCT ID NCT07585162
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how much denture teeth wear down over two years in people who have no natural teeth. It compares three types of teeth made with modern digital methods: 3D-printed, milled from a block, and standard prefabricated ones. The goal is to see which type resists wear best, helping dentists choose the most durable option for their patients.
