Oral navigation may change how dentists work and how they interact with patients. With Navident, dentists can drill without looking at their patients. This simple, clever system works like a GPS, accurately guiding the placement of implants. Navident starts by using CT scan data to map the patient’s mouth, helping the surgeon plan implant placement. Then, during surgery, the dentist is guided by Navident’s optical sensor, which displays information on a graphic software interface. This tells the dentist where the drill is located (with accuracy to 0.5 mm), how close it is to the planned angle and how far from the planned depth. ClaroNav, the company behind Navident, claims a surgeon will be comfortable with the system after using it just a few times. The system allows surgery to be done with less preparation, less swelling and less medication.
