Primary Outcome Measures

Name	Time	Method
<br> 1. Microscopic topography of the implant surface formed after applying each method of mechanical treatments measured using scanning electronic microscope SEM at baseline and 6 months after the grafting process<br> 2. Dimensions of the grafted alveolar ridge in the area of the implant at the transverse plane measured (clinically) using cone-beam computed tomography systems (CBCT) the day following the surgery and 6 months after the grafting process<br> 3. Dimensions of the grafted alveolar ridge in the implantation area at the transverse and vertical levels measured using cone-beam computed tomography systems (CBCT) at baseline and 6 months after the grafting process<br> 4. Gingival health measured using assessment of gingival indices, bleeding on probing (BOP), and peri-implant pocket depth (PPD) at baseline and 6 months after the grafting process<br>

Secondary Outcome Measures

Name	Time	Method
<br> 1. Effect on the keratinized gingiva measured using keratinized gingival width will be measured by a periodontal probe from a reference point at the buccal side of the implant (mid buccal surface of the gingival former) to the MGJ (muco-gingival junction) before the surgery and 6 months after the grafting process<br> 2. Pain after surgery measured using a visual analogue score (VAS) at baseline, 24 h, 48 h, and one week after surgery at baseline and 6 months after the grafting process<br> 3. Patient satisfaction with the surgical procedure measured using patient satisfaction questionnaire (PSQ-18) at 6 months after the grafting process<br>
