Jaw bone quality for implant placement

Tooth extraction usually causes bone shrinkage at the site of extraction. In addition, the longer the time that has lapsed since extraction, the more bone shrinkage occurs. This can leave us with insufficient bone volume for implant placement.

Bone grafts are used to increase the bone volume and prepare the site for receiving dental implants. Implants can then be placed either at the same time as the grafting or at a later date, depending on the current bone volume and the amount of grafting required.

There are different types of bone grafts that can be used. Some of them can be taken from other sites within the same patient. Others are sourced from cadavers or bovine (taken from cows). All the bone grafts we use are Therapeutic Goods Administration (TGA) approved and are extremely safe for dental use.

Improving the jaw bone quality before implant placement

If the tooth that requires extraction has not been removed yet, we sometimes prefer to place a bone graft in the extraction site immediately after the tooth is removed. This procedure is called “alveolar ridge preservation” or “socket preservation.” It aims to preserve as much of the existing bone as possible and reduce the potential for bone loss after the extraction, allowing for better implant positioning during placement.

If the tooth has already been extracted and there is not enough bone for implant placement, the bone must be rebuilt either prior to or during the implant placement procedure. This bone grafting procedure is called “guided bone regeneration” or “GBR.”

A bone graft is used to rebuild or add bone in the jaw, often to prepare for dental implant placement. After a tooth is extracted, the surrounding bone can shrink over time. A bone graft helps restore lost bone so an implant can be securely placed.
Bone grafting can be done either immediately after a tooth extraction (called socket preservation) or before/at the same time as implant placement, depending on the amount of bone present. Your periodontist will assess your needs during the consultation.
We use a variety of safe, TGA-approved graft materials. These may include bone from another area of your body, donor tissue from humans (cadaver bone), or bovine bone (from cows). The material used depends on your case and treatment goals.
Bone grafting is typically done under local anaesthesia. Although mild discomfort may occur afterwards, most patients recover well with pain relief and proper aftercare. Your periodontist will explain what to expect and how to care for the area during healing
Guided bone regeneration is a specific bone grafting technique used when there has been significant bone loss. It involves placing a barrier over the graft to encourage new bone growth and improve the foundation for future implants
