Abstract
Subgingival caries, an existing faulty restoration, or a fractured tooth may not only affect the amount of coronal support but may also extend apically into connective tissue.
In these cases, surgical extension of the clinical crown by means of crown-lengthening procedure is imperative if apical overextension of the subsequent restoration is to be avoided. In other instances, for example an existing excessive subgingival caries or extensive radicular cyst, crown-lengthening procedure or surgical extrusion or a combination of these is indicated. This report we present a case, existence of subgingival caries and radicular cyst in the upper anterior portion.
It performed two surgical procedures, that a crown-lengthening procedure and a surgical extrusion for the crown-lengthening and the removal of radicular cyst prior to restoration. In consequently, this procedure can maintaining appropriate crown length, keeping biological width, and restore esthetically.
