Oral Surgery
Bone Grafting

Bone grafting is commonly performed by an oral and maxillofacial surgeon to replace or augment bone in areas of tooth loss. Bone grafting to the jaws and facial structures may be necessary in a wide variety of scenarios. The most common bone grafts are facial skeleton and jaw procedures. Other common procedures include tooth extraction site graft, bone graft reconstruction and for a sinus lift. Shrinkage of bone often occurs when a tooth is lost due to trauma, severe caries, or periodontal disease. Additionally, bone loss may have already occurred due to infection or pathology around a tooth. There are many artificial biocompatible bone substitutes available; however, the best material for a bone graft is your own bone, which most likely will come from your chin, the back part of your lower jaw or your hip bone. The hip is considered to be a better source because the hip bone has a lot of marrow, which contains bone-forming cells. There are also synthetic materials that can be used for bone grafting. Most bone grafts use a person's own bone, possibly in combination with other materials.

To place the removed bone in the recipient site, little holes are drilled in the existing bone to cause bleeding. This is done because blood provides cells that help the bone heal. The block of bone that was removed will be anchored in place with titanium screws. A mixture of the patient's bone marrow and some other bone-graft material will then be placed around the edges of bone block. Finally, a membrane is placed over the area and the incision closed.

The bone graft will take about 6 to 12 months to heal before dental implants can be placed. At that time, the titanium screws used to anchor the bone block in place will be removed before the implant is placed.

Crown Lengthening

Crown lengthening is a surgical procedure that re-contours the gum tissue and often the underlying bone of a tooth. Crown lengthening is often for a tooth to be fitted with a crown. It provides necessary space between the supporting bone and crown, which prevents the new crown from damaging bone and gum tissue.

Tooth Extraction

Dr. Soboh and Dr. Liswi are experienced tooth extraction dentists in Pomona. When the extraction of a tooth is required:

1) An incision in the gums is made 2) The tooth is removed 3) The area is stitched up and is allowed to heal

During this time, it is important to think about a tooth replacement option. An extracted tooth leaves an open area in the jaw which, in time, allows the neighboring teeth to drift into the area where the tooth was extracted. This in turn, causes a chain reaction to all the surrounding teeth. Also, if you are considering placing an implant in the future, you should consider asking your dentist to place a bone graft at the time of surgery to preserve the bone width and height.

Wisdom Tooth Problems

The problems involving your wisdom teeth may be caused by the size of your jaw and/or by how crowded your teeth are. Common warning symptoms that there is an un-natural problem in the development of your wisdom teeth could be pain and swelling.


Symptoms can be caused by:
1) Infection to the gums
2) A crowded tooth displacing neighboring teeth
3) A decayed wisdom tooth
4) Poorly positioned wisdom tooth
5) A cyst that destroys bone

Wisdom Tooth Removal

Removal of wisdom teeth could be done while you are sedated and being carefully monitored.

1) An incision is made in the gums.
2) The overlaying bone is removed to
expose the crown of the tooth.
3) The tooth is then extracted as a whole or under certain circumstances, it may be necessary to be removed in pieces. This is generally done for severely impacted wisdom teeth.
4) The area is stitched closed and allowed to heal.
