Bone Grafting
Many times due to progressive disease, infection, or trauma, bone and soft tissue are lost in areas around the teeth. Bone resorption or deterioration occurs naturally when teeth are lost or removed unless dental implants are placed to preserve the bone.

Fortunately for those patients who have lost bone, it is possible to augment or replace the bone with grafting techniques and successfully place implants. Any defects in the bone in the front of the mouth can be corrected to create the proper facial contours and tissue support necessary to achieve optimal esthetic results.

If small defects are present in the desired implant location, a bone graft with either real or synthetic bone is used to fill in the defects. Since gum tissue grows faster than bone and will in essence invade the bone graft, causing it to shrink, a thin collagen membrane is used to cover the graft to prevent the gum tissue from growing into the area. Sometimes the bone graft can be accomplished at the same time as implant placement. This type of graft takes the same time to heal as it takes for the bone to remodel after the implants have been placed.

If there is a substantial amount of bone loss, which prevents the placement of dental implants, an actual block of bone can be removed from the chin or behind the lower back teeth and transplanted to the area in need. These “blocks” of bone are held in place using small titanium screws to allow for healing. They will often be covered with a thin collagen membrane to aid the healing process. These grafts typically require four to six months to heal and form new bone identical to the shape of the transplanted block. Implants can then be placed securely in this bone. It will usually take another three to four months for the bone to remodel around the implants.

Platelet Releasing Growth Factor
In addition, Dr. Gray’s office has the newest breakthrough in bone grafting and implant stability, Platelet Releasing Growth Factor. A small volume of your blood is withdrawn. Using a centrifuge and micro-pipettes your Platelet Releasing Growth Factor is obtained, and placed into the surgical site. Studies have shown faster healing and statistically significant, improved 12 week implant stability. Platelet Releasing Growth factor, or PRGF, is one of the reasons that our immediate implant placement results are so good.
Sinus Lift Procedure
This procedure involves elevating the sinus membrane and placing the bone graft onto the sinus floor, allowing implants to be placed in the back part of the upper jaw.
In severe cases the ridge has been reabsorbed and a bone graft is placed to increase the ridge height and/or width.
Ridge Expansion
The ridge expansion procedure, or ridge-split as it is nick-named, is another breakthrough procedure. When bone is lost in an area where a tooth, or teeth are missing, implant placement can be difficult. This procedure separates the available bone and expands what is already there so that it will accept implant placement. In addition to being a work horse procedure it is far less painful than other bone grafting procedures. To make things even better the implant is placed at the same time as the expansion procedure. This decreases your in office time, and saves money over procedures that require multiple visits.
