3D-printed overlays vs. CAD/CAM for damaged back teeth
Part of Mouth & dental clinical trials.
This trial compares two types of tooth-colored overlays (like advanced fillings) for molars that have had root canals and are badly broken down. The goal is to see which type—3D-printed or computer-designed—works better over 18 months.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 60 years old
- You have a lower molar (back tooth) that had a root canal and needs a full overlay (covering the whole top of the tooth)
- You have at least 20 teeth that meet and chew together
- You keep your mouth and gums clean and healthy
- You do not grind or clench your teeth
- You are not pregnant, a heavy smoker, or have serious health problems

This study tests different ways to restore back teeth (molars) that have had root canal treatment using custom-fitted caps called overlays. The goal is to find which design works best to protect these teeth long-term.
This trial compares two modern ways to make partial dental restorations (like crowns or bridges): one using a 3D printer and the other using a computer-aided design and manufacturing (CAD-CAM) system. It aims to see which method works better for people who need a couple of teeth fixed.
This trial tests two types of dental cement (a bioactive kind and a conventional self-adhesive kind) for placing crowns or large fillings on back molars that have had root canals. The goal is to see which cement works better to keep the restoration secure and the tooth healthy.
This trial compares two types of dental crowns (endocrowns) for back teeth—one made by 3D printing and one by milling—to see which fits better and lasts longer. If you have a molar that needs a crown after a root canal, you may be able to join.
This trial compares two digital manufacturing methods to make ceramic onlay fillings for back (molar) teeth—one method that removes material and one that builds it up. It may help you learn which approach makes more comfortable, effective onlays for teeth needing repair.
This trial tests two different types of onlay restorations (like custom fillings) for back teeth that have moderate damage but are still healthy. It is designed for adults with good oral hygiene and no active gum disease or grinding habits.
