Zygomatic Implant

The zygomatic implant enables the precocious load even in case of seriuos atrophy of the upper maxillary, because it must be utilized the bone tissue of the zygomatic process of the maxillary up to the cheekbone cortical.

In our dental clinic the zygomatic implant is applied surgically, with local anaesthesia, via transmucous membrane, with the aid of a surgical guide (SurgiGuide) realized by 3D scanning by volumetric or spiral CAT. In an upper dental arch, already fitted with normal alveolar implants ready for the load, but with with one or two missing implant pillars in the distal region, the proposal is: why delay the load, waiting for the results of one of the mentioned forms of bone regeneration, when it is possible to resort to zygomatic implant? As soon as put in place the ziygomatic implant is ready for the load and is complete with whatever is needed for the relevant prosthesis. The procedure requires a preliminary study: it is needed a CAT scan carried out with the help of a basal plaque or diagnostic prosthesis with barium sulphate 10%. The CAT scan is processed through a software and the relevant data are transferred to the SurgiGuide (Image 6), whose cylinders guide the surgeon, with their orientation and calibre, to carry out faithfully the pre-surgical planning of the intervention. The guided implant surgery is quick and safe for the very reason that it is planned in advance. It is also hardly invasive.

We propose an interesting example of zygomatic implant in a case of impant/prosthesis re-treatment of the upper dental arch.
