Bone grafting

Bone grafting is usually performed when the patient does not have enough healthy natural bone matter in the jaw to securely support the dental implants placed by the dentist. Thanks to progress in the field of dental sciences, today’s artificial bone grafting materials make this intervention relatively simple to perform. If the affected area is extensive, we take a bone graft (a bone block) from other parts of the patient’s jaw or from the patient’s hip bone.

You might need bone grafting when:

  • instead of removable dentures, you prefer to have implant-retained crowns in your up-per and lower jaws, but you do not have sufficient bone matter to support the implants;
  • many years have already gone by since you lost your teeth and the implants cannot be placed securely into your jaw bone because, not being exposed to any load, it has lost density, thickness, and height;
  • the base of your sinus is too close to the surface of your top jaw bone and implantation can only be done after bone grafting and sinus floor augmentation;
  • you are of advanced age and the bone at the floor of your enlarged sinuses has become too thin. If a tooth needs to be extracted from this region, special care must be applied. To ensure the stability of your implants, bone grafting and sinus floor augmentation must be performed prior to implantation.

The procedure

Bone grafting and sinus floor augmentation (sinus lift surgery) are performed in our isolated maximum sterility operating room.

Bone grafting surgery involves the following steps:

  1. The area to receive the bone graft is fully anaesthetised.
  2. First, an incision is made in the gum to explore the bone; then, a “window” is opened into the bone to expose the mucous membrane of the sinus.
  3. The bone flap is lifted by a few millimetres to create a small gap, into which bone graft-ing material is inserted. This will increase the volume of the bone matter towards the si-nus.
  4. A membrane is applied to close the “window”.

If the atrophy only affects a limited bone area, implantation may be performed at the same time as sinus lift surgery. If the atrophy affects an extended area of the bone, and large quanti-ties of bone grafting material are needed, the typical healing and osseointegration period be-tween your sinus lift and implant surgery is about half a year.

Are you considering bone grafting surgery?  Please call +36 30 206 9532 to ask for a consultation appointment with our dental surgeon Dr. Gábor Benedek.

If even more bone is needed for successful implantation, we take a small bone block from the jaw. The bone block is usually taken either from the corner of the jaw bone or from the internal bone matter of the chin. Your facial features will not show any sign of change once the site of the bone graft extraction regenerates. We perform this intervention in our oral surgery operat-ing room under local anaesthesia, without any pain.

If the chin does not provide an adequate bone graft, we take a small block from the blade of the hip bone and graft it into the jaw. This operation is performed in a hospital environment under general anaesthesia and involves a hospital stay of a day or two. We proceed with im-plantation once the bone graft has healed, which normally takes about half a year.

Good to know

In order to determine the extent of bone grafting, we take into account the amount of degradation specified in the literature, which is an average and does not reflect individual differences. It is therefore not possible to exclude that additional bone grafting becomes necessary later.

Subsequent upon improper oral hygiene, prematurely discontinuation of postoperative medication (antibiotics) or other diseases of the body, deformation or excessive absorption may also occur in the bone graft area.
