Dental showdown: onlays vs crowns for saving decayed teeth
NCT ID NCT07259265
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at 120 adults with decayed premolars or molars to compare how long onlays and single crowns last, and how well they work. Participants received either a crown or an onlay made from different ceramic materials. The goal was to see which restoration type and material leads to fewer fractures, maintains tooth vitality, and avoids further decay over time.
