For obtaining adequate retention for restoring cases like subgingival caries or extensive caries that shortens the tooth, short clinical crown, and fractures, it is usually necessary to disclose more tooth structure. Crown lengthening procedure is done to increase the clinical crown length for restorative or esthetic reasons without breaching the biologic width. These procedures are also utilized to improve the appearance and retention of restorations placed within the esthetic zone. We report a case of crown lengthening surgery with an internal bevel gingivectomy which was done in our department without compromising tooth support and esthetics.
为了获得足够的固位力,以修复诸如龈下龋或广泛龋等病例,这些病例会缩短牙齿、临床牙冠较短和发生折裂,通常需要暴露更多的牙体结构。牙冠延长术是为了增加临床牙冠的长度,以达到修复或美观的目的,同时不破坏生物学宽度。这些手术还可用于改善美观区修复体的美观和固位。我们报告了一例在我们科室进行的牙冠延长术联合内斜切口龈切除术的病例,该手术在不影响牙齿支持和美观的情况下完成。
