Advances in the periodontal surgical flaps techniques to preserve gingival papilla

Abstract

Papilla preservation in periodontal surgery is not only beneficial to maintain postoperative aesthetics and good oral hygiene but also contributes to obtaining good periodontal regeneration outcomes. Various periodontal flaps have been designed to preserve the gingival papilla, which constitutes the clinical basis for periodontal open flap debridement and periodontal regeneration surgery. A comprehensive understanding of their design purpose, indications, and technical key points will help clinicians to choose the optimal surgical plan, and thus improve the clinician's treatment levels, and obtain good clinical outcomes. Therefore, this article aims to introduce the design background, indications, and technical key points of various surgical flaps, such as papilla preservation technique, modified papilla preservation technique, simplified papilla preservation flap, etc.
