Sixty-four teeth were treated by means of apicoectomy with retrograde gutta-percha filling with the use of new instruments that we devised. The new instruments consisted of a biangle explorer, angle reamers, and angle files. Operations with this technique showed a success rate of 95.3% (61/64 teeth). We conclude that our technique for apicoectomy with retrograde gutta-percha filling is not only simple in procedure, but also shows excellent results.
