Bone grafting is one type of oral surgery we specialize in at Now Care Dental. Our experienced dentists can perform major and minor dental bone graft procedures—and recommend the appropriate bone graft surgery just right for you.
Bone grafts, sinus lifts (sinus elevation), ridge expansion (ridge modification) are techniques used to rebuild the bone around your jaw and mouth—to create the solid foundation needed for dental implants. We also have the ability to perform nerve repositioning along with tooth bone graft procedures.
With bone graft surgery, we have the ability to grow bone where needed and repair implant sites with a bone graft for dental implants. Patients may not have enough healthy bone to support dental implants because of gum disease, facial injuries, tooth extractions and more. Our dentists are skilled at placing perfectly sized bone grafts for dental implants that restore both the functionality and appearance of your mouth.
Major bone grafts are typically performed to repair defects of the jaw resulting from traumatic injuries, tumor surgery or congenital defects. Large defects are repaired using the patient’s own bone—such as the skull, hip and lateral knee (tibia). These procedures are routinely performed in an operating room and require a hospital stay.
Some roots of the upper teeth extend up into the maxillary sinuses, which are like empty rooms. When these upper teeth are removed, there is often just a thin wall of bone separating the maxillary sinus and the mouth which makes placement of dental implants impossible.
With a sinus graft or sinus lift procedure, we can enter the sinus and lift the sinus membrane and insert bone into the floor of the sinus (the roof of the upper mouth). We can use guided bone regeneration or guided tissue regeneration—so special membranes can dissolve under the gum to help protect the bone graft and encourage bone regeneration.
After several months of healing, the bone becomes part of the jaw and dental implants can be inserted and stabilized in this new sinus bone. If enough bone between the upper jaw ridge and the bottom of the sinus is available, sinus augmentations and implant placement can sometimes be performed as a single procedure.
If there is not enough bone available, the sinus augmentation will be performed first and the graft will have to mature for several months, depending upon the type of dental bone graft material used.
Ridge expansion or ridge modification is a bone grafting technique used to restore the lost bone dimension when the jaw ridge gets too thin to place conventional implants. This type of graft can be performed if the jaw isn’t wide enough to support an implant, or to correct indentations in the jawline as a result of missing teeth.
With a ridge expansion procedure, bone graft material is used to create a small ridge along the top of the jaw. In some cases, dental implants can be placed immediately. But usually a few months of healing is needed before placing the implant.
With nerve-repositioning, the inferior alveolar nerve, which gives feeling to the lower lip and chin, may need to be moved to make room for placement of dental implants to the lower jaw. This surgery is performed in an out-of-office surgical suite under IV sedation or general anesthesia. After discharge, bed rest is recommended for one day and limited physical activity for one week.
This is a very aggressive approach. Almost always there is some post-operative numbness of the lower lip and jaw area, which dissipates very slowly, if ever. Usually other less aggressive options are considered first, like placement of blade implants.
In the nerve-repositioning procedure, we remove an outer section of the cheek side of the lower jawbone to expose the nerve and vessel canal. Then we isolate the nerve and vessel bundle in that area, slightly pull it to the side and place the implants. The bundle is then released and placed back over the implants—the surgical access is refilled with bone graft material and the area is closed.
These procedures may be performed separately or together, depending upon the patient’s condition. When the patient’s own bone is used, we generally get the best results. Bone grafts can be taken from inside the mouth, the chin or third molar region or in the upper jaw behind the last tooth. A larger quantity of bone can be attained from the hip or tibia.
In many cases, we can use allograft bone grafting material for dental implants. Allograft is the transplant of bone from cadavers and promotes the patient’s own bone to grow into the repair site—it is effective and safe. According to the Centers for Disease Control and Prevention, allograft has been used in periodontal bone grafts for more than 30 years—and most bone banks follow the safety guidelines of the American Association of Tissue Banks (AATB).
Synthetic bone graft can also be used to stimulate bone formation. We can even use factors from your own blood to accelerate and promote bone formation in graft areas.
