ClinConnect Summary

This clinical trial is studying a new type of dental crown made from zirconia, a strong and durable material, which can be made quickly in the dental office using advanced technology. The trial aims to see how well these crowns perform over two years. Participants will receive either a self-adhesive glue or a traditional cement to attach the crowns to their teeth. This study is open to adults aged 18 and older who have at least one damaged tooth that needs a crown, such as a tooth with decay or a fracture.

To be eligible for the trial, participants should have at least one tooth that requires restoration and must have enough healthy teeth around it for proper support. However, the study cannot include people with sensitive teeth, untreated dental issues, or certain medical conditions. Participants will need to return for follow-up appointments to monitor how well their crowns are working. This trial is currently recruiting participants, and it offers a chance to receive a new dental restoration while helping researchers learn more about this innovative material.
