Vertical tooth fracture: reunion with a miniature lag screw.

The treatment and prognosis of teeth with crown root fracture are dictated solely by the extent of the fracture line. Vertical tooth fracture, a variant of crown root fracture, presents serious complications in management because of the extent of the fracture line to the full vertical length of the tooth. It is invariably followed by extraction of the entire or a segment of the tooth. Literature recommends various treatment possibilities for vertical tooth fracture, yet no predictable protocol with a long-term prognosis has been described. This case report details a multidisciplinary approach towards reunion of the fractured fragments of maxillary I premolar by providing interfragmentary compression with the use of a miniaturized lag screw.
