Palatal shield technique: a novel approach for improved donor site healing in mucogingival procedures - report of two cases.

Abstract

Objective: Mucogingival surgery involving tissue grafts is commonly employed for cosmetic procedures like root coverage, and is increasingly applied in implant therapy to modulate peri-implant soft tissues and enhance implant survival. These procedures involve harvesting autologous connective or epithelial connective tissue, often from the palate or tuber maxillae. However, this can cause patient morbidity due to postoperative pain. Substitute materials, including animal-derived and xenografts, have been developed but lack qualities of autologous grafts.

Method and materials: To address postoperative discomfort, a novel technique, named "palatal shield," using composite resin stabilized on adjacent teeth's palatal surface is proposed as an aid to donor site healing after mucogingival procedures. Two cases are reported where this technique was successfully applied. The first case involves a 53-year-old woman undergoing free gingival graft surgery for peri-implant treatment. The second case features a 58-year-old man receiving subepithelial connective tissue graft surgery for root sensitivity.

Results: Ten days post surgery, both patients reported excellent postoperative comfort. The technique's effectiveness is highlighted in these cases, demonstrating its applicability in various surgical cases involving free gingival graft or connective tissue graft harvesting.

Conclusion: The proposed "palatal shield" technique offers several advantages, including enhanced patient comfort, ease of application, and cost-effectiveness, making it a promising addition to mucogingival surgical procedures.
