Zygomatic Implants are used especially when there is no bone available to place a regular dental implant. They are used as an alternative to the old conventional technique.
Zygomatic implants is an advanced dental implant technique. As the name suggests these implants are fixed to the zygomatic arch. They are used as an alternative to the old conventional technique. Zygomatic implants are used in the upper jaw that is maxilla.
If the bone present is not sufficient enough for an implant placement then zygomatic implants can be placed successfully as these implants are longer than the traditional implants and are anchored into the jaw bone which is very close to the dense bone Zygoma. Hence these implants act as support to implant bridgework where there has been a substantial amount of bone loss from the upper jaw and traditional implants cannot be used on their own to support a bridge.
Zygomatic implants are also used as the alternative to the dental procedure, which required bone grafts for placements of implants, allowing the procedure to be completed in a single stage. Prior to implant surgery, a CBCT scan is done to assess the amount of available bone and to plan the treatment accordingly.
It is also important to make an anatomical study model of the jaw, which enables the dentists to visualize the precise shape of the jaw and cheekbone, and thus avoiding wide surgical exposure. Typically, two zygomatic implants are used along with other ordinary implants but where the bone availability is even more compromised, four of them may be used.
A fixed composite bridge may be given temporarily on the same day of implant placement till the fixation of a permanent prosthesis.
Other conventional implants are anchored to the jawbones but the zygomatic implants are anchored into dense zygomatic arch giving it strong anchorage.
Other conventional implants are possible only when a sufficient amount of bone is available for anchorage whereas these implants are longer and have dense anchorage, so can be placed in bone deficient areas.
Hence, it eliminates use of bone grafts thus enabling procedure to be completed in a single sitting and faster healing.
Earlier in order to solve the problem of bone deficiency, several bone augmentation procedures were developed. The bone was taken from a donor site (for example the hip), transplanted to the recipient site and then implants were placed. This procedure has to be done under general anesthesia requiring patients to be hospitalized for two-three days and some degree of morbidity related to the donor site was expected.
However, recently other synthetic bone grafts are used to minimize the rate of morbidity. But using bone grafts increases the healing time, sometimes patients might have to wait for more than 1 year before a fixed prosthesis can be delivered.
Furthermore, using bone grafts increases total treatment expenditure. Zygomatic implants are generally inserted through the palate to engage the body of the zygomatic arch.
Most commonly, the zygomatic implants are combined with two to four anterior maxillary axial implants.
You get a fixed prosthesis which satisfies both functional and aesthetical requirement within 24 hours or two to three days as compared to the conventional implant techniques that take up to 6 months.
Sometimes some complexities like prolonged bleeding, swelling, pain, or slight discomfort could be there which can be treated and controlled efficiently. Other complications like haematoma or any other post-operative numbness could be felt which is also controllable. So to avoid any such complexities proper history of the case should be done and all the investigations including radiographs, CBCT scan, and diagnostic models should be done properly.
Zygomatic implants are a highly specialized treatment and are done under general anesthesia, nowadays done under conscious sedation and Local anesthesia also under specialist supervision. These treatments are done only bydental implant specialists or by oral and maxillofacial surgeons.
The below PowerPoint is to explain the procedure and a case study of a patient who came to India from France to get the Zygomatic implants. We did this procedure at The Dental Specialists under local anesthesia. It is a complete graft less solution and did the implants in and loaded it in just 7 days. She went back to her home town in just 7 days.
You may need Zygomatic Implants if you have severe bone loss in the upper jaw and are not a suitable candidate for traditional dental implants or bone grafting procedures.
The procedure is typically performed under general anesthesia or sedation, so you should not feel pain during the surgery. Some discomfort and swelling can be expected afterward, but our dental specialist will prescribe pain medication to manage it.
The cost can vary depending on the complexity of your case, the number of implants needed, and the dental specialist's fees. It's best to consult with our specialist for a personalized cost estimate.
With proper care and maintenance, Zygomatic Implants can last a lifetime. Regular dental check-ups and good oral hygiene are essential for long-term success.
