Abstract
Objectives
Management of the palatal donor site following periodontal plastic surgery remains challenging because of postoperative pain, bleeding, and patient discomfort. This study aimed to evaluate the efficacy of a chairside-fabricated composite barrier in reducing morbidity at the palatal donor site.
Materials and methods
In this randomized, parallel-group clinical trial, 50 patients undergoing soft tissue augmentation were allocated to either a test group (composite barrier + collagen sponge) or a control group (collagen sponge alone). Intraoperative measurements included palatal tissue thickness, graft dimensions, and donor site management time. Postoperative outcomes (pain, bleeding, discomfort, chewing difficulty, stress, analgesic consumption, and willingness for retreatment) were assessed at prespecified time points during the first 2 postoperative weeks. Donor sites complications were specifically assessed on postoperative day 7.
