Osteoplastic – grafts

Volume maintenance of the post-extraction socket.

Right after the extraction of a tooth, the healing process starts with the formation of a blood clot.

After some time, this clot transforms into a bone through the natural process of healing. In order to avoid the absorption and the atrophy of the bone socket in the extraction area, it is ideal that the grafts are placed during the time of extraction.

Process:

  1. The tooth gets extracted.
  2. A careful surgical cleaning is conducted locally.
  3. A suitable graft is placed inside the socket to occupy the empty space.
  4. The graft maintains its volume to help the prevention of shrinkage and atrophy of the post-extraction socket.
  5. The graft acts like a scaffold that is used from the body’s cells, so they can be reborn into a bone in a predictable and effective way.
  6. After 3-4 months of healing approximately, the area can be ready for dental implants placement. The volume maintenance grafts of the post-extraction socket are recommended for every patient’s tooth extraction and we design the bone restructuring and dental implants placement.

TRANSPLANT USING BONE CHIPS
If a tooth is missing in an area, the jaw, eventually, starts getting absorbed leaving a deficit that can’t be rebuild. Bone chips is a method that is used for the restoration of the bone areas that have been absorbed using graft material in the form of granule.

Procedure:
The area is prepared for the material to be placed inside. Graft materials can be received either from the trade (foreign grafts) or from the patient himself. Nevertheless, prefabricated materials are those that are used more often. A sufficient piece of graft is placed in the area and then the graft is covered from soft tissues and gets sewed.
A healing period follows before restoration with dental implants is conducted, that lasts 4-6 months approximately.

Bone block transplant
Bone block transplant is another method for bone restoration of an area where teeth are already lost. Typically, this method is used in cases of greater deficits comparing with those where the placement of bone chips is adequate. In those cases, a larger part of bone is received from the patient and gets placed in the area where there is a bone deficit.
After a period of 3-4 months, the graft is integrated in the jaw bone for the improvement of the bone’s quantity and quality, with the purpose of implant placement. The places that are usually used as a source for this type of graft include the jaw or the third molar area of the lower jaw.

Bone chips vs bone block transplant
A common question brought forward concerning oral surgery is if bone chips should be used instead of bone blocks. Each case is unique and must be examined separately. Therefore, there isn’t an explicit answer. However, for smaller deficits, the grafts in the form of granule are often used in order to avoid the creation of a second surgical field for the graft removal. Larger deficits are predictably dealt by using bone blocks. The creation of a second surgical field to remove the block results in a more intense post-surgical discomfort and swelling. Most of the time the healing percentages are essentially equivalent, as well as the quality and quantity of the resulting bone.

Major bone transplant (Large bone quantity)

In cases of important trauma or pathological situations (cysts, tumors), larger quantities of bone grafts are required to rebuild the jaw bone so that the placement of implants or other restoration procedures are possible. In these cases, the granules (chips) and small bone blocks are considered inadequate techniques for the bone quantity required for the final restoration. In these cases, grafts can be received from the ilium, the parietal bone, the patient’s shinbone etc.
