What is a bone graft?

  • bone-graft-before
    Before bone graft, there was insufficient bone for implant placement.

Bone graft is substitute bone which is used to restore and preserve jaw bone during implant surgery. The majority of dental implant treatment cases require some type of bone graft addition. By placing bone graft after a tooth extraction, you assist the body in growing its own bone. Essentially, the bone graft fills in voids and acts as a space maintainer. This allows your body to regenerate new bone and aids in the healing of dental implants.

Why do we need bone graft?

Bone graft placement assists your body in healing better and preserves your jaw bone structure. Once you lose a tooth, your jawbone continues to shrink at an accelerated rate. Adding bone graft to the tooth extraction site helps preserve your jaw bone. This is important if you are planning on placing a dental implant in the region. For implants to succeed, they must be placed in solid bone structure. Often times, the ideal position for placing dental implants lacks sufficient bone to fully secure your implant fixture. In these situations, your dentist has to add bone graft in preparation for implant placement.

Where do bone grafts come from?

bone-graft-material
Bone graft can be synthetic, from cadavers and from your own body.

There are many different types of bone graft material, each with its own implication and uses. Here is a list of some common bone grafts material used in implant dentistry:

Synthetic bone graft

Synthetic bone grafts is the most commonly used type of graft material. Synthetic bone graft is made from material such as calcium apatite or calcium phosphate. , to fill in smaller voids and defects. These are essentially bone substitutes and void fillers which are used for bone augmentation procedures.

Allograft bone

Allograft is a bone graft which comes from a donor site. These includes bovine bone (from cows), xenograft bone (pig bone) and human cadaver bone. The advantage of allograft bone over synthetic bone is cadaver bone doesn’t get absorbed over time. This makes cadaver bone more effective in preserving voids and thus a better option for repairing larger bony defects.

Autogenous bone graft

Autogenous bone graft is essentially your own bone. Effectively, the oral surgeon harvests your own bone from a donor site within your body. The donor site is typically either the mandible or chin and can occasionally be harvested from your ribs. Autogenous bone graft is typically reserved for repairing the largest bony defects when there are no other alternatives.

All bone grafts function similarly by helping your body regenerate additional bone. They essentially act as a space holder to permit your own bone to grow into the graft area. As your own bone grows, it absorbs and replaces most or all of the bone graft material. Once you have enough solid bone, your dentist can now securely lock in the dental implants in place.

What is a sinus lift or sinus graft?

Sinus-Lift-Graft
A sinus lift or sinus graft is performed to restore sufficient bone near the sinuses and allow for implant placement.

A sinus lift or sinus graft is required when there is not enough bone to place dental implants in the upper posterior region. For those of you with a knowledge of teeth numbers, this includes teeth #2, 3, 4, 13, 14, 15 and occasionally teeth #5 and 12. The upper posterior region of your jaws typically lacks sufficient bone for implant placement. This is primarily due to its proximity to the maxillary sinuses. A sinus lift or sinus graft is performed to restore sufficient bone near the sinuses and allow for implant placement. Here is a bit more information about sinus lifts and sinus graft surgeries:

Sinus lift surgery

sinus-lift-dental-surgery
During a sinus lift, your dentist will push your sinus membrane up.

You require a sinus lift when there is approximately 5 to 8 millimeters of bone under your sinus membranes. This is a routine procedure commonly required for placing dental implants in the upper posterior region. During a sinus lift, your dentist will push your sinus membrane up. This creates additional room so that a proper sized dental implant can be placed.

Lateral wall sinus graft

lateral-wall-sinus-graft-dental-surgery
When there is less than 5 millimeter of bone under the sinuses, a sinus lift will not restore sufficient bone for implant placement and you require a lateral wall sinus graft instead.

A lateral wall sinus graft is required when there is hardly any bone under your sinus membranes. Typically, when there is less than 5 millimeter of bone under the sinuses, a sinus lift will not restore sufficient bone for implant placement. In these circumstances, your dentist must perform a surgery known as lateral wall sinus graft. First, your dentist will access your sinus cavities using a CT scan. Then, he or she will create an opening in the upper jaw using a lateral wall approach. Next, your dentist will separate and gradually lift your sinus membrane. Finally, your dentist will add a significant amount of bone graft material to prepare the area for implant placement. As you’d imagine, a sinus graft is a major operation and requires adequate preparation and planning.

When do you need a bone graft or sinus graft surgery?

A bone graft is needed whenever there is not enough jaw bone to place dental implants. Your dentist will access your jaw bone using X-rays such as a CT scan or Panoramic radiograph. if you have sufficient jaw bone, then your dentist can proceed with dental implant surgery. However, if you don’t have enough bone structure, then a grafting procedure is required. The type of grafting procedure depends on the where the implants are being placed and how much original bone structure you have.
