Abstract

|
Minimally invasive periodontal surgery was recently designed to improve the flap stability, maintain space for regeneration and preserve an increased portion of the blood supply at the level of the bone crest and papilla. However, the soft tissue esthetics were not fully preserved, following the various surgical approaches with buccal flap elevation. The aim of this case report is to evaluate the results of minimally invasive surgeries with palatal approach in the maxillary anterior intrabony defects. Four patients with localized intrabony defects in the maxillary anterior regions were included in this study. The surgical approach consists of a limited palatal incision in which only the palatal flap is elevated, while the papilla is left in place. The buccal tissues are not involved in the surgery. Bovine-derived xenograft material with or without resorbable membrane was applied into the defect for regeneration. In all cases, the intrabony lesions were resolved without complications. The results demonstrated significant pocket depth reduction with limited buccal gingival recession. The radiolucent areas were filled with bone-like tissues, and buccal gingival shape was maintained for 6~30 months. Minimally invasive surgical approaches in the regenerative periodontal therapy may be effective compared to that of conventional treatment.
