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

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.
