影响龈乳头高度的因素

Factors influencing the height of gingival papilla

口腔软组织美学已越来越受重视。龈乳头形态是影响口腔软组织美观的重要因素之一。龈乳头高度的丧失导致黑三角的形成。在前牙区,黑三角不仅带来功能性问题,也影响发音和美观。国内外学者对影响龈乳头高度的因素进行了一系列研究,包括患者年龄,牙龈生物型,以及牙冠外形、接触点-牙槽嵴顶距离、牙间距、根间分离角、龈外展隙形态等形态学因素。临床医生必须了解评估龈乳头高度的参数才能准确地判断治疗效果及实现龈乳头的再生。

Oral soft tissue has been a highlight topic these days. The morphology of gingival papilla is one of the most important factors influencing esthetics of oral soft tissue. The loss of gingival papilla height leads to black triangle. In anterior region, the black triangle not only results in functional disorder, but also brings in speech problems and esthetic concerns. Researchers from home and abroad reported some morphological factors influencing the height of gin- gival papilla： Age, gingival biotype, crown form, contact point-crest distance, interdental distance, divergence angle, embrasure morphology, etc. Clinicians must understand the factors that influence the presence of the interproximal papilla in order to prognosis the state of the papilla and to better fulfill the regeneration of lost gingival papilla.
