ClinConnect Summary

This clinical trial is studying two different methods for making dental onlays—these are restorations used to repair badly decayed molars. Researchers want to compare traditional CAD/CAM milling, which removes material from a solid block to create the onlay, with a newer method called 3D printing, which builds the onlay layer by layer. The goal is to see which method is more efficient and produces better results while minimizing waste.

To participate in this trial, you need to be between 25 and 45 years old, have at least one decayed molar that needs an onlay, and maintain good oral hygiene. You should also be able to understand and agree to the trial's procedures. Participants can expect to receive either a 3D printed or a CAD/CAM milled onlay and will help researchers learn more about these two techniques. It's important to note that individuals with certain habits, health issues, or cognitive impairments may not be eligible to join.
