Dental implants are small titanium posts which are placed into the jaw bone in order to replace missing teeth. In order for implants to be placed correctly adequate amounts bone are needed for implant placement. During the initial assessment for implant treatment the dentist or implant surgeon will asses to see if sufficient bone is present for implant placement. CT scans or radio-graphs are used to analyses the jaw bone prior to placing implants. If there is insufficient bone, a bone graft for dental implants treatment may be needed.
A bone graft is the process of adding structure to your existing bone in order to give an appropriate base for the implant. The bone in your jaw can be stimulated to grow either through natural or synthetic means.
After tooth loss a natural process of bone shrinking usually occurs. The tooth socket fills with new bone however the surrounding bone shrinks after the tooth is removed. If the tooth is not replaced with an implant, then the bone loss will continue. Each year a small amount of bone will be lost and over time this may make implant placement complex. Similarly to natural teeth dental implants prevent bone loss. Implants provide a stimulus to the jaw bone and maintain bone around the implant. There are various types of bone graft for dental implants
There are four types of bone grafts:
In dental implantology bone grafts are usually carried out under local anesthetic or sedation. Most procedures do not require hospitalization and can be performed in the dental chair. More complex bone grafting procedures like hip grafts will require general anesthetic and hospitalization. A healing period of up to 9 months is needed for some types of bone graft procedures.
Bone graft procedures are usually highly predictable and successful. There are different types of bone grafting procedures with some being more complex than others. There are several reasons why bone grafts fail however the most common is infection. During the healing phase bacteria in our mouths can infiltrate the graft and cause infection. Antibiotics are usually prescribed before bone grafting in order to reduce the possibility of infection. However if the graft becomes infected it will need to be removed. It is very important that removable dentures are avoided as much as possible after bone grafting procedures.
