Bone Grafting An Overview
Dr. Datta is a leading Northern Virginia dentist for the placement of dental implants, offering complete and comprehensive services under one roof. He will use advanced digital imaging and 3-D scanning to thoroughly evaluate the health of your jaw bone and determine if augmentation of the bone structure through a bone graft is necessary.
The density and structure of your jaw bone is a key factor in the long term success of dental implants. Genetics, physical condition and the length of time teeth have been missing can impact bone in the jaw and be the cause of bone loss or shrinkage of the jaw area. When teeth are lost and the tooth root no longer exists in the gum tissue, the body begins the natural process of resorption, slowly absorbing the “unnecessary” bone tissue and changing the overall fit and appearance of your smile over time.
A bone graft will involve the removal of a small amount of bone from one area of the jaw or the more common use of a biocompatible material similar to bone tissue. This bone or material is then placed into areas where the bone has been determined to be thin, weak or too soft to maintain a dental implant.
After a period of time for healing and osseointegration, your new dental implants can be successfully placed in the jaw, which can now support the long term success of the new restoration.
Types of Bone Grafting
Patients can have insufficient bone in different areas of the mouth, depending on where teeth have been lost or as a result of other conditions or trauma. After analysis with 3-D scanning, Dr. Datta can pinpoint areas where bone needs to be augmented in order to support a dental implant.
- Sinus augmentation: if the upper teeth have been lost at the back of the mouth the open sinus area may have expanded or bone has thinned due to resorption. Bone can be grafted along the upper sinus area to restore a stable foundation for an implant.
- Ridge expansion: a narrow jaw may require a ridge expansion to accommodate dental implants. A bone graft can be placed where the alveolar ridge has deteriorated to help recreate the natural structure that will support the implant.
Bone grafts can also be placed along the gum where a tooth is missing and the supporting bone beneath has begun to change and shrink.
