ClinConnect Summary

This clinical trial is looking at two types of zirconia crowns, which are dental restorations used to replace missing teeth. Specifically, it aims to compare a new kind of multilayered zirconia crown to the traditional monolithic zirconia crown, both of which are fixed onto dental implants. The goal is to find out if the new crowns perform just as well as the conventional ones in terms of success rates and patient satisfaction.

To participate in this trial, individuals need to be at least 18 years old and have a partially missing tooth area that is suitable for restoration. They should be generally healthy, have good oral hygiene, and have healthy dental implants already placed in the back of their mouth, either in the molar or premolar areas. Participants can expect to have their dental health monitored throughout the study and will help researchers understand which type of crown works better for people needing dental implants. It's important to note that certain conditions, like smoking or untreated dental issues, may prevent someone from joining the trial.
