Reasons for Bone Grafting
Some bone grafting procedures are more involved than others. Typically, any grafting done in preparation for dental implants or to fill an empty bone socket can be considered minor. Bone grafting to correct any jaw irregularities, however, may be considered major. Dr. Stearns can perform bone grafting to assist with nerve repositioning, ridge augmentation, sinus lift surgery, and socket preservation.
Nerve Repositioning
At times, dental implant placement may require repositioning of the inferior alveolar nerve. During a nerve repositioning procedure, the surgeon will typically expose the nerve and vessel canal by removing an outer section of the cheek on the side of the lower jaw bone.
The nerve and vessel bundle in that area is then isolated and pulled out slightly to the side, and the surgeon will place the implants. Bone graft material then refills the incision site before being closed.
Ridge Augmentation
Bone grafting can also help restore the alveolar ridge bone to its original state. Commonly performed after a tooth extraction, a ridge augmentation aims to recreate the natural contour of the gums and jaw. Usually, these contours are lost due to bone loss from a prior tooth extraction.
After tooth extraction, there is an empty socket in the alveolar ridge bone. This socket will usually heal on its own. However, it sometimes breaks and deteriorates.
Sinus Lift
Additionally, bone grafting can help raise the sinus floor and allow for new bone formation. Sinus lift surgery, also known as sinus augmentation surgery, may be necessary if the sinus wall is too thin to place dental implants in the bone. Bone loss in this area occurs due to injury or periodontal disease.
Socket Preservation
Finally, after tooth extraction, the bone (or socket) that once held the tooth in place may become damaged by disease or infection. Eventually, this may result in a deformity of the jaw. Jaw irregularities can be incredibly obstructive when it comes to performing restorative dentistry treatments. Socket preservation can help prevent them.
In this procedure, the socket is filled immediately with bone or bone substitute after extraction. Afterward, the surgeon will cover it with gum, artificial membrane, or tissue to aid in the healing process.
