preparationandtheimplantplacementprocessare tracked in real time. The Navident tracking system uses an on-screen visual representation of the sur- gical area and auditory cues to aid the clinician (Figs. 10a & b). Two XPEED AnyRidge implants (Megagen) were installed. At region #15, an implant of 4 mm in lengthand13mmindiameterwasplaced,whereas at region #25 an implant of 10 mm in length and 3.5 mm in diameter was placed (Figs. 11a & b & 12). After completion of the dental implant place- ment, a crown-lengthening procedure was per- formed in the anterior maxillary region in order to ameliorate the aesthetic outcome. It is beyond the purpose of this report to provide any detail regard- ing this procedure. _Prosthetic procedure Immediately after implant placement, impres- sion copings (Megagen) for an open-tray impres- sion were screwed on to the implants and hand torqued (Fig. 13). An impression was taken at im- plant level using a silicone material (Permadyne Penta H, 3M ESPE Dental) in a plastic Position Tray (3M ESPE Dental). Within 8 hours, two temporary screw-retained acrylic teeth were delivered to the patient and connected to each of the implants. The acrylic teeth were designed based on temporary ti- tanium abutments. Occlusion and articulation were checked and corrected wherever necessary. All superstructures were hand torqued to a maxi- mumof15Ncm.Nocantileverswereallowedonthe provisional structures in order to avoid extensive non-axial forces. Postoperatively, the patient re- ceived a prescription for antibiotics (amoxicillin 1,000 mg, b.i.d., four days), non-steroidal anti-in- flammatory drugs (ibuprofen 600 mg, t.i.d.) and a mouthwash (chlorhexidine 0.12%, b.i.d.). After one week,apostoperativevisitwasscheduled.Nosigns of infection or inflammation were present and healing was uneventful (Figs. 14 & 15). _Conclusion With a two-week postoperative follow-up, this was the first immediate loading procedure based ontheNavidentnavigationsurgerysystem.Thepa- tient reported no pain or swelling associated with the dental implant procedure. Further postopera- tive results are being tracked and reported as part of a pilot study being conducted at Ghent Univer- sity (Figs. 16a & b)._ Editorial note: A list of references is available from the publisher. case report I Fig. 12_Post-op panoramic image.
