Bone Grafts

Chicago prosthodontist

Bone grafting is commonly used as a preparatory procedure for patients who require dental implants.

Grafting is a process of repairing damaged or deficient bone with mineral material also known as Guided Tissue Regeneration. Non-organic minerals fill the void left by infections, missing teeth and aging. When minerals are in contact with a patient’s blood, the graft turns into new bone within 4-6months. Bone grafts are different from transplants, in that they do not contain organic material. Without organic material, bone grafts are not subject to rejection as observed in transplantation procedures.

There are three main sources of grafting materials used in dentistry:

  1. SyntheticMan-made materials usually mixture of calcium and phosphates
  2. XenograftsAnimal bone derived minerals
  3. AllograftsHuman bone derived minerals

Most sources agree that all three types of bone replacement have similar clinical success rates. Preferences on which materials will be used should be discussed during the consultation. The material selection can be based on experience, patient’s preference and ethics.

There are three main types of bone grafts:

  1. Socket Preservation Grafts – bone grafts performed right after tooth extractions; used to repair and prevent loss of bone during healing. Bone replacement material fills the void left by the tooth extraction
  2. Onlay Graftsbone grafts performed long after a tooth has been lost; used to repair and regenerate thinned bone on its’ periphery (outside) as a result of infections, missing teeth and aging
    1. Particulate grafts – bone added in the form of particles, usually reserved for small to moderate defects
    2. Block Graftsbone added in the form of blocks, usually reserved for moderate to large defects
    3. Sinus Augmentation Graftsbone grafts performed in the upper molar areas usually long after tooth has been lost; used to repair and regenerate thinned on the inside of the sinus cavity


You may need bone grafts if:

Teeth have been lost a long time ago

•Teeth have been lost due to infection

•Teeth have never developed – congenitally missing teeth

•Teeth have been lost due to trauma

•You are losing a molar tooth and preparing for an implant

•You are preparing for immediate implant replacement


 Why do I need bone grafting?

Dental bone grafts are also commonly used following tooth loss, gum disease, or to maintain bone structures after a tooth extraction. Without healthy facial bone structures, the skin that is supported by the bones is affected, and may lead to patients appearing prematurely aged. In most cases, a bone graft can help restore a patient’s bone structure to the necessary shape and give way to successful implant treatment.

Do I need to have grafting before my implant?

Bone grafts may either simultaneously accompany implant placement or may be performed six months prior to implantation. The exact sequencing of treatment varies depending on circumstances specific to your case. Major Dental Clinics uses 3D Cat Scans to evaluate the amount of residual bone and the need for bone regeneration.

Cost of Bone Grafting

Bone grafting procedures vary greatly and depending on the clinical situation, the costs may range anywhere from $300 – $2000 per tooth site. Each bone graft is used for a specific reason, therefore it is very important to discuss treatment options with your dental specialist during your consult.

Major Dental Clinics dental specialists are highly skilled in bone grafting procedures. They will discuss the type of grafting necessary, benefits, and risks of each procedure as it specifically pertains to you.
