Clinical Trial Summary

This study will evaluate how the crown's shape under the gums will influence the gum tissue around dental implants.

Description:

This research is studying the transmucosal contour, or shape of crowns (white-colored tooth structure that sits above the gum) under the gums on dental implants. Participants will be randomly selected for the dental implant crown to be designed with either a straight or concave transmucosal contour, and followed up on for 1 year after crown delivery.
