We use Zygomatic implants routinely when there is not enough bone for ordinary implants. Zygomatic implants are used to provide support for implant bridgework under the following two circumstances.
- Where there has been a substantial amount of bone loss from the upper jaw
- And as a result, ordinary dental implants cannot be used on their own to support a bridge.
The implants are longer than ordinary dental implants and engage the very strong bulk of bone that forms the cheekbone. This means that the implants can be used as an alternative to complex bone grafting operations, making it possible to carry out surgery in just one simple stage.
Typically two Zygomatic implants are used along with 2-4 ordinary dental implants. Where bone availability is even more limited, four zygomatic implants may be used.
We routinely fit a fixed resin bridge on the same day as the implants are placed. This has been incredibly exciting for our patients. This is because most of our patients have been able to get rid of their dentures in just one day. Earlier they had graft treatments over a 9-18 month period in several different surgeries.
Treatment with Zygomatic Implants is very similar from the patient’s perspective to conventional implant treatment. Treatment usually starts by ‘designing’ the teeth by making a ‘set-up’ arrangement of teeth in the new desired position. As patients who need Zygomatic implants have usually lost large amounts of supporting bone this can make a huge amount of difference. They include factors like appearance and correcting the collapse or loss of face height. The loss of face height is often present with patients who have wearing dentures for a long time.
We use 3-D scanning technology to produce a precise replica model of the upper jaw bone. This allows us to visualize the precise shape and topography of the jaw and cheekbone, without having to carry out a wide surgical exposure. We often use special ‘guides’ that help us to accurately put implants directly into the correct position. So as to make the experience as comfortable as possible. This sort of treatment usually takes place under intravenous sedation or general anaesthesia.
