Abstract

Abstract : Introduction: Free autogenous graft was the gold standard to increase the keratinized mucosa (KM) and vestibular depth. The major downfall of this technique is the postoperative morbidity at the donor site. The purpose of this case report is to demonstrate a modified technique using acellular dermal matrix (ADM) to increase the KM around implants to achieve faster healing with less postoperative morbidity. Case Presentation: Patient presented with inadequate keratinized tissue band and shallow vestibule at submerged implant sites bilaterally. Initially, surgical procedure of vestibuloplasty in conjunction with free gingival graft (FGG) was performed at one side. However, patient opted for the allograft as a substitute for the other side due to the postoperative discomfort from palatal donor site. On the left side, the FGG procedure was performed in a conventional way stabilizing with sutures. On the right side, the ADM was stabilized with tacks only at recipient site and left exposed. The new vestibule was established and stabilized with tacks. A significant gain of KM and vestibule depth was observed at the site of using ADM when compared with baseline. For the site of using FGG, KM was increased. However, the vestibule was rebounded compared with the site of using ADM with tacks. Conclusions: The use of ADM stabilized with tacks is a predictable procedure that can increase KM and establish stable vestibule around dental implants. It can lead to less chair time, faster healing, and reduced postoperative morbidity compared with autogenous soft tissue graft.
