Various vestibular extension procedures have been described in the literature over the past 6 decades, including the use of free gingival grafts. An acellular dermal allograft has been used as a substitute for autogenous soft tissue grafts in root coverage procedures. This clinical report describes the use of such an allograft as a substitute for palatal donor tissue in the vestibular extension of an edentulous maxillary arch with multiple frenum attachments before fabrication of a complete denture. In this patient, healing was uneventful, and 6-month clinical observations demonstrated an apical positioning of the mucogingival junction with an increase in vestibular depth, and the absence of multiple frenae. The acellular dermal allograft appears to be a useful substitute for autogenous palatal grafts in preprosthetic surgery. This approach has many advantages over the free gingival graft, including no donor site morbidity, unlimited availability, and better color match.
在过去60年里，文献中描述了各种前庭扩展手术，包括使用游离牙龈移植。脱细胞真皮同种异体移植物已被用作根面覆盖手术中自体软组织移植的替代品。本临床报告描述了在制作全口义齿之前，使用这种同种异体移植物替代无牙上颌弓多个系带附着处前庭扩展时的腭部供体组织。在该患者中，愈合过程顺利，6个月的临床观察显示黏膜牙龈交界处根尖定位，前庭深度增加，且无多个系带。脱细胞真皮同种异体移植物似乎是修复前手术中自体腭部移植物的有用替代品。这种方法比游离牙龈移植有许多优点，包括无供区并发症、可用性不受限以及颜色匹配更好。
