Once a tooth has been removed, the jawbone in the area reshapes and shrinks over time. This may result in a situation where there is insufficient bone available to allow the placement of a dental implant.
It is often possible to rebuild the missing bone, so that a dental implant can be placed. This may also allow a dental implant to be placed in the ideal position, resulting in a more aesthetic appearance.
Minor bone grafting procedures can be carried out under local anaesthetic in the dental chair. A bone grafting material may be used to rebuild the missing bone. The material is usually covered with a special membrane, which is used to protect the bone graft and encourage the growth of new bone. This procedure is referred to as guided bone regeneration.
Bone grafting may be carried out at the time a dental implant is placed, or can be required prior to this. The timing of the bone grafting procedure may be determined by the amount of bone regeneration required (i.e. the size of the bony defect) and whether the implant can be placed in an ideal position. Your Periodontist will advise you as to what is suitable for you.
