I industry report encountered with conventional methods involving transferring virtual positions to the actual model. TheCTVsystemprovidesforreliablepostoperative examination once the implants have been placed. This means that unerringly precise congruency is achieved between planning dataset and postopera- tive 3-D radiological dataset for comparing the ac- tual implant positions with the planned positions. It is irrelevant whether the planning and control datasets stem from the same machine (Figs. 8 & 9). This enables the user to check for success at an early stageaswellasanalysethecauseofanyerrorswhich may occur. This should lead to errors being avoided long-term (learning effect). Of course, the CTV system can generate compre- hensive and custom expandable, forensically de- pendable case documentations at the push of a but- ton. They can be stored as PDF files, printed and/or forwarded. The use of RFID chips integrated into the model of the jaw ensures that the CTV system stores a complete documentation of the responsibilities as part of the total process (Fig. 10). _Conclusion The combination of radiological and optical data and simultaneous integration of CAD/CAM processes enables errors to be identified at an early stage and, together with suitable compensation measures, leads to a much better match between planning requirements and outcome. The numerous options for combining images create optimum con- ditionsforinterdisciplinaryunderstandingaswellas explaining the therapy strategy to the patient in a plausible and understandable manner. The indica- tions of this new technique range far beyond mere implant planning and can be used in-house without having to purchase costly special equipment and transfer units._ 40 I implants3_2013 Diagnosis Preplanning Realisation of planning positions Definite Planning Planning Doctor Dental-Lab.
