Zygomatic implants are different from conventional dental implants in that they anchor in to the cheek bone rather than the maxilla/ upper jaw. They may be used when maxillary bone quality or quantity is inadequate for the placement of regular dental implants.
Zygomatic implants avoid grafting and sinus lift procedures and therefore contribute to a shorter and more comfortable treatment.
Further indications for zygomatic implants include failed conventional implant placement.
failed sinus augmentation or grafting procedures.
rehabilitation after tumor and trauma resections.
In the atrophic posterior maxilla, in general one zygomatic implant is placed on each side of the maxilla, in combination with 2-4 conventional implants in the anterior region.
For the totally resorbed maxilla, when placement of anterior implants is not possible the concept can be expanded by inserting 2 additional zygomatic implants in a more anterior position (Quad zygoma).
Zygomatic implants nowadays are usually immediately loaded with a fixed bridge.
The benefits to a patient of using a Zygoma or Quad Zygoma implant solution include:
2.Normal-looking teeth and gums
3.Freedom to eat what you like
4.Teeth that do not come out
5.No more denture sore spots
6.Long term tooth support
7.Faster healing than bone grafting
High success rates with only minimal complications. The cumulative survival rate of zygoma implants is 96% after 12 years.
The reported complications are post operative Sinusitis, infra orbital nerve parasthesia ,oro antral fistula. All these complications can be avoided when proper diagnostic and surgical protocols are followed.
Is the treatment is painful?
The procedure of placing a Zygomatic Implant is similar to conventional implant placement but is performed under general anesthesia by an experienced Oral and Maxillofacial surgeon.
