Multilayered PRF versus connective tissue graft for anterior implant tissue health
Official title: Evaluation of Multilayered PRF in Comparison With Connective Tissue Graft by Sohn Poncho's Technique on Peri-implant Mucosal Enhancement in the Esthetic Zone. A Randomized Clinical Trial
Run by Gulf Medical University · NCT07649239 · Data updated 2026-11-12
This study tests whether multilayered platelet-rich fibrin can improve soft tissue around front-mouth dental implants as well as the traditional connective tissue graft.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 21–65 with a single missing tooth in the esthetic zone, good oral hygiene, and stable periodontal health.
✕Probably not a fit
Patients with poor oral hygiene, smoking, or systemic conditions affecting healing may not benefit from PRF treatment.

What this trial studies
This interventional study compares multilayered PRF membranes with the standard connective tissue graft during the second-stage surgery around single anterior dental implants. It focuses on enhancing peri-implant mucosal thickness and the width of keratinized tissue to achieve better esthetics. Outcomes center on tissue stability and healing in the anterior esthetic zone, with a 2nd-stage healing period. Eligible participants are adults 21–65 with good oral hygiene and a single missing tooth in the esthetic area. Smokers and medically compromised individuals are excluded to limit healing confounders.
Why it matters
Potential benefit: If successful, patients may achieve thicker, more stable peri-implant tissue and better esthetic outcomes with less morbidity than a connective tissue graft.
How similar studies have gone: Previous studies in other regions suggest PRF can match connective tissue graft outcomes for mucosal thickness, but anterior-region data are limited.

Show full inclusion / exclusion criteria
-Inclusion Criteria: Patients with single bounded missing tooth in the esthetic zone Patients in the age group of 21-65 years Patients having good oral hygiene (mean plaque score of \< 25%) and with stable periodontal status. -Exclusion Criteria: Smokers patients Patients with poor maintenance of oral hygiene, as determined by a mean plaque score of ≥ 25% despite efforts by the clinician to improve oral hygiene maintenance. Patients with medically compromised conditions like uncontrolled diabetes mellitus or any systemic diseases that may result in compromised hard and soft tissue healing.
