Design outcomes

Primary

Measure	Time frame
Gingival (gum) thickness at the buccal aspect, measured in millimeters using: 1. Cone beam computed tomography (CBCT) 2. Bone sounding (gold standard/transgingival probing) 3. Ultrasonic probe 4. Digital caliper All measurements are taken at a single timepoint during preoperative assessment (before any surgical intervention, after local anesthesia, within a 15-minute window per patient)	—

Secondary

Measure	Time frame
There are no secondary outcome measures	—
