Before dental implant surgery, bone grafting is sometimes necessary to supplement the bone mass of the patient's jaw so that the implants can be anchored firmly.
Sunnyvale Implant Dentist Dr. Gupta is committed to doing everything necessary to ensure the success of every dental implant procedure. That means bone grafting will be performed, if required, to ensure that your dental implants provide you a beautiful smile for years to come.
When is Bone Grafting Necessary?Loss of bone volume can be caused by a variety of factors, including infection, trauma, and periodontal (gum) disease. If a patient lost a tooth long ago and is just now looking into dental implant surgery, it’s likely that the bone around the lost tooth has degenerated to some degree and needs to be augmented before it can support an implant.
A patient’s need for bone grafting may become apparent at the time of their pre-surgery X-ray at Sunnyvale Dental Care Practice.
Sometimes, inadequate bone volume is not discovered until the dentist actually begins dental implant surgery. In this case, the dental implant procedure will be halted and bone grafting will take place after the patient has agreed to the procedure.
Types of Bone GraftsThere are three types of bone grafts, each named with regard to the source of the bone used in the procedure:
- In an autogenous bone grafting procedure, bone is harvested from one area of the body and transferred to another.
- In an allograft procedure, either synthetic bone or cadaver bone is used to augment the jaw bone.
- In a xenograft procedure, cow bone is used.
When performing an autogenous bone grafting procedure to augment the jaw for dental implants, the dentist usually takes bone from the chin or back part of the lower jaw and transplants it to the area that will eventually provide the platform for the implants.
Major and Minor Bone GraftingOver a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants. However, today, we have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore functionality and esthetic appearance.
Major Bone Grafting
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. The bone is most commonly obtained from a tissue bank or your own bone is taken from the jaw. Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration.
Major bone grafts are typically performed to repair defects of the jaws. These defects may arise as a result of traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patient’s own bone. This bone is harvested from a number of different sites depending on the size of the defect.
