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