To compare between the efficacy of fascia lata allograft and platelet rich fibrin versus subepithelial connective tissue graft on periodontal phenotype (thickness and width of keratinized tissue, labial bone thickness) around dental implant in upper anterior region.

In order to evaluate the effectiveness of fascia lata allograft, platelet-rich fibrin, and subepithelial connective tissue graft on periodontal phenotype (including the thickness and width of keratinized tissue, as well as the thickness of labial bone) around dental implants in the upper anterior region, the purpose of this study is to compare the three types of grafts.

Inclusion Criteria:

1. Patients with thin gingival biotype (gingival thickness was ≤1 mm)
2. The height of keratinized gingiva for the site selected should be ≥2 mm.
3. Ability to maintain good oral hygiene as evidenced in recall visits.

Exclusion Criteria:

1. Smoker patient and pregnant or lactating woman.
2. Patient with poor oral hygiene or active periodontal disease.
3. Traumatic occlusion or para-functional habits such as clenching or bruxism.
4. Patient with limited mouth opening

Patients age ranged from 20 to 50
