[Retrograde apicoectomy. Development of a new technique and its clinical application]

We developed a new technique instead of usual retrograde apicoectomy for cases in which apical lesions appear after prosthetic treatment. The technique is as follows. After treatment of the apical area by raising a flap, part of the labial bone is removed and the labial surface of the root is exposed. Then the labial part of the root is removed and the root canal is opened. After that, the residual carious dentin is removed completely. At the final stage, the open root canal is filled with tooth adhesive and low viscosity composite resin (Clearfil-SC). This technique is indicated for cases in which the crown restoration is not removed for some reasons and treatment from apical side is not possible. This technique is clearly the last choice, but many teeth will remain.
