ClinConnect Summary

This clinical trial is studying the effectiveness of two different types of collagen membranes used during a procedure to build up bone around dental implants. This is important for patients who need a single-tooth replacement, especially in the front part of the mouth, where appearance matters. The trial will also look at how different finishes on the crowns (the visible part of the implant) affect their durability over time. Participants will receive an implant along with a bone-building procedure, and then a crown will be placed after healing. The study aims to see if one type of collagen membrane provides better bone stability and whether certain crown finishes are more prone to chipping.

To be eligible for this trial, participants must be at least 18 years old and need a dental implant for a single-tooth gap in the front of their mouth. They should not have any active gum disease, and their overall dental health should be good. Participants will need to attend follow-up appointments over the next seven years to monitor the stability of their implants and crowns. If you're considering joining this study, it's a great opportunity to help improve dental procedures while receiving careful monitoring for your own dental health.
