Study Details

Brief summary:

The study will examine the temporary volumetric change that happens in the gums around an implant crown when the crown is removed. The main question of the study is "how much time has to pass to see a significant change, especially when there could be a need to make a mold of the surrounding gum to make a new crown?"

The area of the implant crown will be scanned with an intra-oral scanner over a period of 15 minutes.
