Like the rest of your body, bone also undergoes cyclical regeneration, with new bone cells replacing old ones. In some cases, however, bone loss can lead to potential complications, including increasingly complex treatment. Dental bone loss in particular can be of significant concern. If there is no bone volume, dental implants cannot be placed. This is why dental bone grafts may be necessary when you need tooth implants to replace damaged or lost teeth.
What are Bone Grafts for Tooth Implants?
A dental bone graft is a surgical procedure that involves adding bone material to the jaw to support the placement of dental implants. This bone material is taken from other bone sources, either from other parts of your body or a deceased human donor. Some bone grafts are from pigs or cows. Some are synthetic or lab-grown substitutes.
A bone graft is typically performed when you have lost one or more adult teeth to gum disease. Gum disease erodes the alveolar bone. A bone graft replenishes the eroded jaw bone and acts as a strong base. Dental implants can then be securely osseointegrated with the newly formed jaw bone.
Why are Dental Bone Grafts Needed?
Dental bone grafting is essential to properly support dental implants, ensuring each implant is securely placed while maintaining your jaw’s and facial aesthetics. They are also used to treat various dental conditions.
Injuries or Trauma
Bone fractures can occur and damage the jawbone. If dental implants are necessary, bone grafts are needed to rebuild the missing part of the bone to anchor the dental implants.
Also known as periodontal disease, gum disease can contribute to bone and tissue damage, leading to tooth loss and reduced bone mass. Dental bone grafts may help reverse this damage for dental implants to be placed.
Developmental Issues
Some individuals are born with congenital jaw defects that can lead to tooth loss, a deformed jaw, or other functional complications. Dental bone grafts help restore your jaw’s structure.
Types of Dental Bone Graft Materials
Dental bone grafts can be derived from various materials, produced by natural or synthetic means.
Autograft
An autograft is harvested from your own bone. It enables live cell transplants into the area where bone grafting is needed, facilitating healing and bone regeneration. Since it is taken from your bone, there is no risk of immune system rejection, which could cause complications. However, an autograft requires additional surgery to obtain it from the donor site (usually from other parts of your jaw bone) and may increase recovery time.
Allograft
Allografts are harvested from deceased donors, removing the need to harvest your own bone for bone grafting. They are readily available from bone tissue banks and can be obtained in various shapes and particle sizes to meet specific needs.
Xenograft
Xenografts are derived from animal-based sources, including bovine bone and coral. They feature a calcified matrix that helps support your jawbone and promote bone growth.
Alloplastic Materials
These are lab-grown, synthetic materials with bioactive properties that aim to stimulate your tooth structure’s healing and regeneration.
Dental Bone Grafting Techniques
Dental bone grafting also involves various surgical approaches, each addressing specific cases of dental bone loss or damage.
Socket Graft
This technique is performed immediately after a tooth extraction to preserve existing bone at the extraction site. It is considered the most straightforward bone grafting technique, as it involves placing the bone graft material into the open extraction socket. In doing so, the bone graft can promote healing and minimise further bone loss, with recovery generally taking about four months if no complications arise. This allows the dentist to follow up with installing your dental implants as soon as you have healed from the bone grafting.
Block Bone Graft
This technique creates a bone block that fits a gap in your jawbone, particularly in cases of substantial bone loss. The bone is typically sourced from the back of your jawbone close to your wisdom teeth, though allografts may also be used. This bone block is then secured in place with titanium screws. Recovery from a block bone graft may take five months or more.
Sinus Lift Graft
A sinus lift graft is performed to treat bone loss in the upper jawbone by elevating the sinus floor. The procedure raises the sinus floor to accommodate the dental bone grafts. Recovery may take several months to allow the upper jawbone to heal. The dental implants are then placed into this newly grafted area.
Dental Bone Grafting Costs in Singapore
The cost of dental bone grafting can depend on various factors, including the type of dental bone graft material, the number of dental bone grafts required, and the need for dental implants. The final cost will also include additional procedures to diagnose and treat your dental condition, including consultation, diagnostic scans (CT scans and X-rays), and supporting treatments. The complexity of treatment may also influence the overall cost of your procedure.
Typically, dental bone grafting may cost SGD 1,000 or more for simple procedures. However, you may commonly see prices range from SGD 2,000 to SGD 8,000, depending on the overall complexity of the treatment and the type and technique of the dental bone grafts used. The good news is that, for some types of bone graft. part of the cost is claimable under Medisave, though this applies only to Singaporeans and permanent residents.
