Navigation System Approach in Zygomatic Implant Technique.

In some patients, the resolution of severe maxillary atrophies can be hardly achieved without the use of zygomatic implants. Although many scientific studies have already demonstrated the excellent immediate stability in long term, the use of zygomatic implants is not yet widespread. Among the complications of this technique, the most threatening is the risk of damaging the eyeball or the maxillary nerve. The use of the navigator system as a surgical aid for implant placement allows to control, at any time, the position of the drill in the bone, avoiding any injury to ocular and nervous structures. The authors present a clinical report which shows a patient affected by a very severe form of post-traumatic maxillary atrophy that has been solved through the of zygomatic implants placement using the "Implant Bone Navigation" system. This procedure allows both to cut down the risks on ocular and nervous structures of the maxilla and also to reach excellent rehabilitation results in such severely compromised patients.
