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

@#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.

Conservative and esthetic closure of maxillary midline diastema without creating "black triangle" using direct resin composite

Anterior diastemas are common esthetic problems. One of the challenges in clinical esthetic dentistry is closing anterior diastemas without creating “black triangles” between the teeth. The success of a restorative treatment in anterior teeth depends on the esthetic integration between soft tissues and hard tissues. This report describes the successfully accomplished diastema closure case by producing the emergence profile with natural contours at the gingival-tooth interface and then generating of gingival recontouring process.

Diastema closure with direct composite: architectural gingival contouring / 대한치과보존학회지

One of the most challenging task in closing anterior diastema is avoiding "black triangle" between the teeth. This paper reports a case that the closure of diastema in anterior teeth could be successfully accomplished using direct adhesive restorations and gingival recontouring. The traditional technique using Mylar strip was modified to increase the emergence profile with natural contours at the gingival-tooth interface. Mylar strip was extended out of the sulcus by approximately 1 mm high from the gingival margin, and a small cotton pellet was used to provide the emergence contour. This modified approach is acceptable for the clinical situation.
