Research progress on the gingival papilla reconstruction / 口腔疾病防治

ABSTRACT

@#The morphology of the gingival papilla plays an important role in the aesthetics of oral soft tissue. Gingival papilla recession forms a visible black triangle, causing a series of problems such as aesthetic defects, pronunciation disorders and food impaction and even endangering the health of periodontal tissue. Gingival papilla reconstruction is an effective way to eliminate the black triangle. However, the treatment of lost or collapsed gingival papilla is unsuccessful. Reconstruction of the interdental papilla for aesthetics zone is the most difficult and challenging periodontal treatment. In this article, we review the past literature and summarize the factors affecting the appearance of gingival papilla, including the distance between the contact point and the alveolar crest, the distance between roots, divergent roots, interdental width, embrasure morphology, crown shape, and gingival biotype. The classification of the gingival papilla based on the loss of papillary height and the nonsurgical and surgical methods for the reconstruction of gingival papilla are reviewed to provide a reference for doctors to reconstruct the gingival papilla.
