Abstract

Abstract:

Complicated crown-root fracture involves enamel, dentin, pulp, cementum and periodontal tissue, which usually requires comprehensive consideration to determine the treatment plan, rebuild the health of periodontal tissue and retain a favorable long-term prognosis. This article presented the sequential treatment to a complicated crown-root fractured permanent central incisor in children, which included the exposure of the fracture margin by the modified crown lengthening, fragment reattachment, root canal treatment, and fiber post reinforcement. The modified crown lengthening surgery removed a small amount of bone tissue, which maximally preserved the original periodontal support of the affected tooth. After 2 years of follow-up, the biological width was reconstructed around the affected tooth, which maintained the desirable aesthetics and periodontal health.

Key words: Complicated crown-root fracture, Crown-lengthening surgery, Fragment reattachment, Sequential treatment, Fiber post
