Examining gum changes after removing an implant crown

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study investigates the temporary volumetric changes in the gums surrounding an implant crown following its removal. It aims to determine the time required to observe significant changes in the gum tissue, which is crucial for creating aesthetically pleasing final crowns. Participants will have their implant area scanned immediately after crown removal and at intervals of 1, 2, 3, 5, 7, 10, and 15 minutes. The study will also involve a final scan when a new crown is made to assess any changes in the gum shape over time.
