Zygomatic Implants

Zygomatic Implants

Where are zygomatic implants placed?

Dental Implants are a away to replace missing tooth with something that looks, feels and mimics a natural tooth. When these implants become difficult to place in the upper jaw bone, research has developed newer and more advanced ways of implant placement. The cheekbone which is also known as the malar bone, is technically known as the ‘zygomatic bone’. It is the main anchorage for the zygomatic implant placement. When implants are planned for the upper jaw, it is normally a difficult situation. The upper jaw may pose few of the following problems:

  • Poorer quality of bone available in the upper jaw as compared to the lower jaw due to age or bone resorption.
  • Decreased width and height of bone over time may be due to various factors.
  • The presence of air spaces or sinus in the upper jaw may also reduce the available height of bone in the back tooth regions.

Hence, having a weak bone in the upper jaw is one of the major causes for zygomatic implants. So when there isn’t enough height of jaw bone to support an implant, the cheekbone is used to take support by providing longer size implants. The advantage of this will be that implants may not get easily affected like a conventional implant from the infection since the size of the implant is longer and the malar bone being thick is resistant to diseases. This method may be mainly used for severely resorbed upper jaws and is designed to allow immediate replacement with fixed polymer teeth.

How is a zygoma implant placed?
The zygoma implants are placed for the eating teeth of the jaw and are approached within the mouth, along with the placement of additional dental implants in the front region of the jaw. If the case is found to be too severe, two zygomatic implants may be placed on each side, which is known as Quad Zygoma. In cases of severe complexities, a custom made implant may be suitable. With proper planning and expertise, the implant treatment can be completed on the same day. The fixing of the tooth can also be done immediately.

Who are ideal patients for Zygoma implants?

  • Complete loss of teeth in the upper jaw
  • Extreme loss of bone in the upper jaw
  • Adults and elder adults as well
  • People who desire to chew frequently on hard food
