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.

Results

All participants completed the study without dropouts. Compared with controls, the composite barrier group required significantly shorter wound management time (210.42 ± 52.04 vs. 445.76 ± 77.43 s; p < 0.001) and lower analgesic consumption during the first week (1328.00 ± 846.33 vs. 4160.00 ± 1366.26 mg; p < 0.001). Pain scores were significantly lower in the composite barrier group on postoperative days 1–7 (p < 0.001), slightly higher on day 10 (p = 0.007), and similar on day 14. Bleeding scores were lower during the first 4 postoperative days (p < 0.001). Patient-reported discomfort, chewing difficulty, and stress were significantly reduced in the composite barrier group (p < 0.001), which also showed greater willingness for retreatment (7.80 ± 1.15 vs. 2.04 ± 1.34; p < 0.001). No necrosis, infection, or hematoma occurred.

Conclusions

Application of a composite barrier for palatal donor site management reduces the time required to achieve intraoperative hemostasis and is associated with lower postoperative pain, bleeding, and patient discomfort. This approach may improve patient-reported outcomes following periodontal plastic surgery.

Trial Registration

This project was registered in the Iranian Registry of Clinical Trials under the ID (IRCT20250513065721N2), and the registration date was 21/6/2025.

外周密封复合屏障（PSCB）用于粘膜牙龈手术中腭供区管理：一项随机临床试验。

目的：由于术后疼痛、出血和患者不适，牙周整形手术后腭供区管理仍然具有挑战性。本研究旨在评估椅子制造的复合屏障在降低腭供区发病率方面的功效。材料与方法：在这项随机、平行组临床试验中，将50例接受软组织增强术的患者分为试验组（复合屏障+胶原海绵）和对照组（单独胶原海绵）。术中测量包括腭组织厚度、移植物尺寸和供区处理时间。术后结果（疼痛、出血、不适、咀嚼困难、应激、镇痛药消耗和再治疗意愿）在术后前2周的预定时间点进行评估。在术后第7天特别评估供体部位并发症。结果：所有参与者都完成了研究，没有中途退出。与对照组相比，复合屏障组创面处理时间明显缩短（210.42±52.04 s vs. 445.76±77.43 s）； p结论：应用复合屏障进行腭供区管理可减少术中止血所需时间，减少术后疼痛、出血和患者不适感。这种方法可以改善牙周整形手术后患者报告的结果。试验注册：本项目在伊朗临床试验注册中心注册，注册编号为IRCT20250513065721N2，注册日期为21/6/2025。

期刊介绍： Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
