Inoue Dental Clinic in Obihiro city has introduced an Implant Navigation System called “Navident” made in Canada. This is the latest device introduced first in Hokkaido, and the entire Japan has only 10 such devices.

Director Hiroyuki Inoue of the Inoue Dental Clinic (2 Chome-12-2, Nishi 9 Jōminami, Obihiro-shi, Hokkaidō 080-0019, Tel: 0155-25-6480) holds the Japan’s leading technology as the implant surgeon. This hospital has introduced the latest medical device, to improve further the accuracy of surgery.

The implant surgery involves drilling a hole in the facial bone with a dental drill, and placing the implant there. It is common to take a CT scan (computed tomography image) of bone shape, passage of blood vessel and nerve in advance for each person, and then make a surgical plan.

However, the current state is that the drilling is done by sense and “Intuition” based on the experience, because the bone condition cannot be seen during the surgery. The devices to decide the insertion direction of drill beforehand are available, but the problem is that the direction cannot be changed during surgery.

Meanwhile, the Implant Navigation System “Navident” was developed and made in Canada.

The CT data is synchronized with the computer, and the position of drill, blood vessel and nerve are accurately displayed in 3D (three-dimension) during the surgery. The position of drill and patient’s jaw are followed by monitoring and using the CT scan like a map, and navigating to the planned implant position.

If compared with the painting, the conventional surgery was made as a free hand drawing in a canvas based on the image drawn in the head. On the other hand, Navident draws the picture with absolute accuracy while tracing the draft. Accuracy improves greatly.

There are only 10 devices introduced in entire Japan. Inoue Dental Clinic became the first in Hokkaido.
