Professional Med J Jan ;23(2):233-7.

Fractured incisors are restored with composite resin is a routine procedure. The retention of composite restoration is related to the bond strength of adhesive and the surface area existing for bonding. In absence of adequate bonding areas in fractured tooth of younger individuals with resilient dentin, additional retention through placement of self threaded pins will give the required support and maintain esthetics. additional retentive means, in the form of pins are often required for restoration of damaged and broken tooth, particularly in adolescent patient’s teeth where pulp chamber is comparatively large, dentinal tubules are relatively immature and still gingival lines are high. The threading acts scatter and devour some of the placing energy by cutting part of pin channel in the dentinal walls. This case report fuses the retentive feature of self threaded pin with the esthetic advantage of composite restoration in fractured anterior teeth.
