Clinical and Volumetric Evaluation of Soft Tissue Augmentation Using Connective Tissue Graft in Pontic Site Defects With and Without Fixed Partial Dentures

What this Trial Is About

Researchers are evaluating soft tissue augmentation using a connective tissue graft (CTG) in patients with pontic site defects, focusing on sites with and without an existing fixed partial denture (FDP). The study investigates whether performing CTG around an existing bridge can provide similar or improved clinical and volumetric outcomes compared to sites without a bridge. The goal is to address alveolar ridge resorption after tooth extraction, which often causes soft tissue problems affecting esthetics and function. Participants will undergo a standardized surgical procedure involving CTG harvested from the palate and placed at the pontic site using a minimally invasive pouch technique. The study compares two groups: those with pontic site defects and an existing FDP where the prosthesis remains during augmentation, and those without an FDP who will receive a temporary bridge during healing. All procedures occur under controlled clinical conditions with initial periodontal preparation. During the study, patients will have clinical and digital assessments before surgery and at follow-ups up to six months. Measurements include keratinized tissue thickness and width, volumetric soft tissue changes, esthetic scores, plaque index, post-operative pain, and patient satisfaction. Monitoring aims to evaluate healing, tissue stability, and esthetic results, supporting a less invasive treatment approach that may reduce discomfort and treatment time.
