Simultaneous guided bone and soft tissue regeneration with dental implants in the maxillary premolar region: clinical application of acellular dermal matrix for functional and aesthetic rehabilitation

Background: Dental implants are widely used for the replacement of missing teeth and have shown predictable long-term outcomes when appropriate surgical and prosthetic protocols are followed. However, successful implant therapy requires sufficient alveolar bone volume and stable peri-implant soft tissues. In situations where ridge resorption and thin mucosal phenotypes are present, regenerative procedures may be required to establish a favourable biological environment for implant placement. Guided bone regeneration (GBR) and acellular dermal matrix (ADM) grafting are commonly used techniques to improve both hard and soft tissue conditions around implants (1–3). Case Presentation: A 42-year-old male patient presented with missing maxillary premolars and complained of difficulty during mastication. Clinical and radiographic examination revealed horizontal ridge deficiency and a thin peri-implant mucosal phenotype. Implant rehabilitation was planned with simultaneous hard- and soft-tissue augmentation. Management and Outcome: Two dental implants were placed in the maxillary premolar region. Guided bone regeneration was performed using particulate bone graft material and a resorbable collagen membrane to address the buccal bone deficiency. An acellular dermal matrix graft was also placed to increase soft tissue thickness around the implants. Healing was uneventful, and prosthetic rehabilitation was completed after confirmation of osseointegration. At 12-month follow-up, the implants remained stable with healthy peri-implant tissues and satisfactory aesthetic integration. Conclusion: The combined use of guided bone regeneration and acellular dermal matrix grafting can effectively address both bone deficiency and thin soft tissue biotype, thereby improving peri-implant tissue stability and supporting long-term implant success.
