Comparing two types of tooth caps for root-canal-treated molars
Part of Mouth & dental clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Age 18–70 years
- Healthy gums with no active disease or poor hygiene
- No tooth grinding, nail biting, or other jaw habits
- A back tooth (molar) that has had root-canal treatment, lost at least one cusp, and needs a cap
- The tooth still has good contact with your bite and neighboring teeth
- You can attend check-up visits at 1, 2, and 3 years

This study compares two ways to restore teeth that have had root canals, focusing on back teeth. It aims to see which approach is more conservative and effective, which may help preserve more of your natural tooth and improve long-term outcomes.
This study compares two ways of making a dental crown for a back tooth that had a root canal. It aims to see which method lasts longer and works better over two years.
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 study compares two types of resin onlays (custom‑made fillings) to see which works better for molars that have had a root canal. If you have a back tooth with a root canal and a cavity on the top and one side, this trial may help decide the best repair.
This study tests three different methods (digital, conventional, and biomimetic) to restore a back tooth that had a root canal and needs a crown-like covering. It aims to find which approach works best over one year.
This study compares two ways to make a strong cap (overlay) for back teeth that had root canals and are badly damaged. It tests a 3D-printed ceramic filling against one made by a computer and milling machine, and follows up for 18 months to see which works better.
