What are Zygomatic Implants?
Zygomatic implants are used in the upper jaw when there is insufficient bone for ordinary implants. They provide support for implant bridgework where there has been a substantial amount of bone loss from the upper jaw, and ordinary implants cannot be used on their own to support a bridge.
This is a very specialist procedure and Bath Spa Dentistry is one of a few practices in the UK with the expertise to use such procedures.
The implants are longer than ordinary dental implants and ‘anchor’ to the very strong bulk of bone that forms the cheekbone, or zygomatic arch – hence their name. 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 stage. Prior to zygomatic implant surgery, a CBCT scan will be taken to assess the amount of bone available in the upper jaw and allow us to plan the placement of these implants.
It is also possible to make an anatomical model of your jaw, which enables us to visualise the precise shape of the jaw and cheekbone, without having to carry out wide surgical exposure. Typically, two zygomatic implants are used along with 2-4 ordinary implants. Where bone availability is even more limited, four zygomatic implants may be used.
Guided surgery may even be used to assist accurate placement of zygomatic implants. A fixed composite bridge may be fitted on the same day as implant placement, allowing patients a permanent alternative to their dentures in just one day.
To make the experience as comfortable as possible, this sort of treatment usually takes place under intravenous sedation.
