| cone beam supplement dynamic navigation Dynamic navigation for reliable and predictable flapless implant placement Author: Dr David Burgess, United Kingdom Fig. 1 Fig. 2 Fig. 1: The patient’s upper right first molar and second premolar had been Case report missing for several years. Fig. 2: Pre-op radiograph. A 52-year-old female patient was concerned about the appearance of her smile. Her upper right first mo- lar and second premolar had been missing for several years (Figs. 1 & 2). She was otherwise a fit and healthy non-smoker.

Fig. 3 42 CAD/CAM 4 2017 The patient was unwilling to consider a denture and was not keen for the symptomless adjacent teeth to be prepared for bridgework, particularly the upper right first premolar, which was unfilled. She did not wish to have any form of removable prosthesis. She chose to have implant-supported crowns, as she wanted the final restoration to be as close as possible to having natural teeth. Clinical examination and planning Clinical examination suggested that the bucco- palatal width of the maxillary ridge was wide enough to consider flapless surgery. This had added appeal, as the patient was travelling a great distance for the treatment, so wished to minimise the number of appointments and the potential for postoperative complications. Computer-guided dynamic navigation with Navi- dent by ClaroNav was used in the preparation of this case. Scanning and planning took place during the assessment visit, 48 hours before implant surgery. A NaviStent was fabricated and a fiducial marker at- tached, prior to the CBCT scan. Fabrication of the
