When the tooth is removed part of the alveolar bone surrounding it may be lost (due to infection for example). It is often necessary to regenerate this bone in order to place the implant under good conditions. For more informations don’t hesitate to contact Dr Diss Antoine, surgeon dental specializes in dental implant in France.
Why is bone graft used?
After performing a scan, the dental surgeon assesses the bone volume available for insertion of an implant. This volume may not be sufficient:
- In terms of height, namely around the upper molars (near the sinus) and lower molars.
- In terms of thickness, in the anterior or posterior zones.
It then becomes necessary to regenerate the lost bone by carrying out a bone graft. Depending on the clinical case in question, this graft may be carried out before or at the same time as mounting of the implants.
During the healing process, this material will be completely or partially broken down and slowly replaced by your own bone. This is known as bone regeneration.
How does this take place?
- During surgery, the bone is placed where the bone defect is found.
- If it is used as a block, it can be screwed in with small titanium screws.
- If it is used in particles, it can be stabilised with the aid of a membrane which acts as protection for the graft.
After an infection or simply after extraction of a tooth, the quantity of remaining bone may not be sufficient for mounting of an implant.
It is often necessary to carry out bone grafting around an implant in order to complete the bone volume.
