Design outcomes

Primary

MeasureTime frame
Width of keratinized tissue around dental implants. Timepoint: Keratinized gingival width is achieved in patients 3 months after surgery. Method of measurement: A periodontal probe is used to measure the distance between the gingival margin and the mucogingival junction.

Secondary

MeasureTime frame
The depth of the vestibule. Timepoint: 3 months after surgery. Method of measurement: The distance from the gingival margin to the deepest part of the vestibule.
