Comparing two 3D-printed resin overlays for large cavities in back teeth
Part of Mouth & dental clinical trials.
This study compares how well two different 3D-printed resin fillings (called 'overlays') hold up over 18 months on back teeth that have large cavities or broken fillings. It involves up to 3 visits and aims to find the best way to prepare the tooth for the filling.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 20 to 45 years old.
- You are a healthy adult and not pregnant or breastfeeding.
- You have at least one back tooth (molar) with a large cavity or a broken filling that needs a custom 'overlay' restoration.
- The tooth must still have a live nerve (no root canal or infection).
- You do not have habits like heavy teeth grinding, and you are not in orthodontic treatment.

This trial tests two different types of tooth-colored fillings for large cavities in adult back teeth: one made with 3D printing technology and one placed in a single layer. The goal is to see which holds up better over time.
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.
This trial tests a special printed material used for tooth overlays (caps that cover the entire top of a back tooth). If you need a full overlay on a molar that has had root canal treatment, this study may be a good fit.
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.
This trial tests two types of dental overlays (ceramic and composite) for molars that have had root canal treatment. It aims to see which one wears better and affects natural teeth less.
This study compares two ways to restore (cap) back teeth that have had root-canal treatment and lost a cusp or more. Researchers want to see which method—computer-milled or 3D-printed crowns—works better and lasts longer.
