Dental implants are designed to fill the gap left by missing teeth. Tooth loss can occur for a variety of reasons, one of the most common causes of tooth loss is due to gum disease. In certain cases where tooth loss occurs, bone loss can also occur.
In a typical situation, dental implant is placed and given time to intergrade to the surrounding bone, then a supporting crown is attached to the implant to mimic the look of the natural tooth. In cases of severe bone loss, it is possible for your body to reject a dental implant due to the lack of supporting jawbone.
This technique attempts to regenerate bone loss and promote growth, through the use of special bone rings. These bone rings support the dental implants used to replace the missing tooth.
At PM Oral Surgery, Dr Simon Wright uses a revolutionary technique called the 'Bone Ring' bone augmentation technique. While this well-known technique is carried out by oral surgeons overseas, Dr Wright is one of the few oral surgeons to practice this revolutionary technique in Australia.
For dental implants to be successfully placed, the jawbone must have enough bone to support them. Through a specially developed technique by Dr Giesenhagen in Germany, known as 'Bone Ring' 3D bone augmentation, bone rings and dental implants are placed in a single operation.
Dental implant surgery has traditionally involved treatment in two stages over a period of up to 10 months. Using the bone ring technique, surgery is performed in a single procedure.
With this new method, treatment time for patients is reduced by approximately five months compared to the two-stage method that required a secondary process called block bone augmentation. The second surgical procedure is no longer required.
PM Oral Surgery is one of a few surgeries in Australia that uses this bone ring augmentation technique. This type of procedure is done in the surgery under local anaesthetic with intravenous sedation (IV) to ensure that patients are less anxious during the surgery. For a single tooth replaced the operation will take approximately an hour.
Bone harvesting takes place either on the chin, palate (roof of mouth) or retromolar (back of mouth after the last molar) area. The recipient site is then prepared and the bone ring removed with special trephine drills. If required, the surgeon will remove root fragments, followed by immediate bone augmentation and insertion of the bone ring together with the dental implant.
The gum tissue is then stitched back into its original position to cover and protect the surgical area. The stitches are small and hardly visible and dissolve within a couple of weeks.
