Summary The integration of CBCT into Boyne


Dental and Implant Clinic has increased the predictability of the treatment carried out. By providing a more accurate diagnosis there is added conf idence that a successful treatment outcome will be achieved. It has already proved to be an extremely useful addition to the armamentarium for the management of complex endodontic problems.
