Design outcomes

Primary

Measure	Time frame
Tissue thickness. Timepoint: At least 6 months postoperatively. Method of measurement: Gingival thickness would be measured using a an endodontic spreader placed in the center of a silicone stopper and inserted perpendicularly from the midbuccal point (3 mm apical to the gingival margin) through the soft tissues to reach a hard surface.	—

Secondary

Measure	Time frame
Probing depth; bleeding on probing; O’Leary plaque index; gingival recession; vestibular depth. Timepoint: At least 6 months postoperatively. Method of measurement: Probing depth would be measured at 4 points (mesial, distal, midbuccal, and midlingual) from the gingival margin to the bottom of the sulcus. Subsequently, a mean value of the measurements would be calculated for each tooth. Bleeding on probing would be recorded within 60 seconds of probing depth measurement. Gingival recession would be measured from gingival margin to the cementoenamel junction. Vestibular depth would be measured from the midbuccal gingival margin to the mucobuccal fold, while a retractor was placed in the mouth and teeth would be in occlusion. The periodontal probe would be held vertically across the vestibule in line with the axis of each tooth.	—
