Surgical crown lengthening in subgingival cariesand fracturedtooth

Main Article Content

กาญจนา พงศ์จรรยากุล


Surgical crown lengthening is a surgical procedure which aims to increase a clinical crown height for restorations and esthetics. To maintain appropriate gingival biologic width includes both the connective tissue attachment and the epithelial attachment. Invading the biologic width with a restoration can result in gingival inflammations, gingival recession and localized crestal bone loss. This article presents two cases of subgingival caries, crown and root fracture involved gingival attachment. A surgical crown lengthening procedure is needed to establish the biologic width. Follow up three months and one year after insert crown found normal periodontal tissue, no inflammations, normal periodontal pocket depth, no bone loss and mobility
