Initial Situation
The patient presented with a severely reduced vestibular depth and inadequate keratinized mucosa in the edentulous maxilla, complicating prosthetic rehabilitation and long-term peri-implant health. The lack of attached gingiva and vestibular height posed challenges for stable soft tissue support and adequate prosthesis seating.

Treatment
A full-arch reconstruction was performed using multiple implants combined with soft-tissue augmentation using mucoderm^®, an acellular collagen matrix, to increase keratinized tissue width and vestibular depth. The matrix was placed under a mucoperiosteal flap and secured to promote revascularization and stable integration without the need for autologous tissue harvesting.

Results
Postoperative healing demonstrated significant gains in vestibular depth and keratinized tissue width, which were maintained over six months follow-up period, allowing for a stable and functional prosthetic outcome. The patient achieved improved soft-tissue architecture with excellent tissue maturation, favorable color and thickness.
