Comparing the effect of two different grafts, one derived from the palate and the other from the patient's blood, on the improvement of gum tissue thickness around dental implants

INTERVENTION: The present study was a split‐mouth controlled clinical trial. For each study participant, one site was treated with SCTG while the other was treated with PRF membrane during dental implant placement. Treatment outcomes included the assessment of the facial gingival thickness using cone‐beam computed tomography (CBCT) at the baseline (T0) and 6 months postoperatively (T1), and the Pink esthetic score (PES) at T1 and 3 months later after prosthesis placement (T2). CONDITION: Peri‐implant soft tissue repair ; Oral Health PRIMARY OUTCOME: Change in peri‐implant soft tissue thickness measured using cone‐beam computed tomography (CBCT) at the baseline (T0) and 6 months postoperatively (T1) SECONDARY OUTCOME: Esthetic improvement measured using the Pink esthetic score (PES) at T1 and 3 months later after prosthesis placement (T2) INCLUSION CRITERIA: 1. Bilateral missing teeth in the maxillary anterior and premolar area 2. Facial thin gingival phenotype facially (i.e. ?1.5 mm) as evaluated using cone‐beam computed tomography (CBCT) (Claffey and Shanley 1986) 3. Bilateral edentulous sites dimension of at least 5.5mm bucco‐lingually, 5.5mm mesio‐distally, and with a minimal bone height of 8 mm 4. Teeth adjacent to the selected edentulous site must be free of periodontal disease involvement 5. Adjacent teeth permit occlusal guidance 6. An opposing dentition to the edentulous area with teeth, implants or fixed prosthesis
