Fully Digital Direct Technique for CAD-CAM post and core restorations – a case report
Restoring the endodontically treated teeth is highly problematic without residual hard tooth tissues and destruction at the gingiva level -no ferrule effect. One possibility is to make post and core restoration. Aim. This article aims to establish the time needed to produce post and core restoration and temporary crown by the fully digital direct method. Materials and Method. A patient visited for restoration of a fractured tooth 34. We decided to make CAD-CAM post and core restoration and temporary crown by fully digital direct methods. Results. The total time estimated was three clinical visits or 180 minutes, with a standard time for one clinical visit of 60 minutes. Conclusion. Within this clinical case, we found that three clinical visits or 180 minutes were required for the fully digital production of computer-assisted posts and cores of chromium cobalt and a temporary 3D-printed crown. The accuracy of the recovery is acceptable. Further research is needed in this direction.
