Dental implant navigation system using a registration-ready tooth template
Purpose
Dental implant surgery requires drilling a hole in the jawbone carefully observing the other organs’ possible damage. There are several complications that should be avoided, which are penetration to maxillary sinus or incisive canal, damage to mandible nerve, and over-drilling outside jawbone. Surgical navigation can be a great help to avoid these complications, because it displays the current drill tip position and near critical organs. In this study, we designed a patient specific tooth template that has both markers for registration and markers for position reference. Using this template, patient to image registration can be performed before the surgery. The operation time is not extended for the registration. We applied the developed navigation system to three implant surgeries and confirmed its feasibility.
We have been using an infrared navigation system at the time of surgery dental implant to perform minimally invasive and safe treatment in this way. We are contributing to a safe minimally invasive treatment has been surgery or brain tumor also used to cochlear implant surgery otolaryngology a navigation system with infrared markers were attached to the maxillary teeth also. At present we are developing a robotic system support dental implant surgery.
