Periodontal regeneration therapy has developed tremendously since its inception, becoming a clinical tool to preserve the periodontally compromised natural dentition. More challenging esthetic defects can often benefit from the combination of bone and soft tissue regeneration, such as the application of connective tissue grafts (CTGs) and techniques that approach the bone defect without interdental papillae incisions. However, periodontal tissue regeneration vertical to the alveolar bone crest in cases of severe periodontitis, with loss of both soft and hard tissues, has not been predictably established. This case report describes a patient with severe periodontitis that was treated with in supra-alveolar periodontal tissue reconstruction. This innovative surgical technique requires both horizontal buccal incisions and several vertical palatal incisions, avoiding the interdental papillae on the periodontal defect. Then, a space is created by suspending and fixating the flap coronally, and CTG and regenerative materials (such as recombinant human fibroblast growth factor-2) and bone graft material are applied. This technique has the potential to gain clinical attachment, achieve supra-/intraperiodontal regeneration, and enhance esthetic outcomes, including a reduced gingival recession and interdental papillae reconstruction. The clinical results of the present case were well maintained over the 2-year follow-up.
