What Causes Bone Deficiency?
- Gum and bone disease
- Tooth loss
- Bacteria on root surface
- Hereditary Anatomy
How To Manage Bone Deficiency?
There are two types of bone grafting, one is to help maintain your natural teeth, the second is to build back deficient bone for dental implants
Bone Grafting With Tooth Extraction
- Socket preservation graft is performed in order to repair or maintain the area of the jaw where a tooth is being extracted.
- This is sometimes the first step in replacing a missing tooth with a dental implant.
- Bone from a tissue bank is utilized to preserve the socket where the tooth was extracted.
- We only utilize bone graft material that has passed the strictest requirements set by the American Association of Tissue Banks (AATB) and the Food and Drug Administration (FDA).
- Once the bone is placed in the socket and given time to heal your bodies natural healing process will dissolve the bone graft and replace it with your natural bone.
- Once healed this new bone can be utilized for dental implant placement.
- This procedure is for areas that socket preservation graft was never completed and the bone resorbed or shrunk.
- This procedure is completed by reflecting the gum tissue back, exposing the bone, placing the bone graft material and a membrane over this graft.
- Either a non-resorbable or resorbable collagen membrane is placed over the graft then your gum tissue is pulled up and over the bone graft site and gum tissue is sutured closed.
- This site is allowed to heal for roughly 3-6 months prior to implant placement.
- In some cases a growth factor is utilized to promote bone growth and healing.
Lateral Window Sinus Augmentation
- To replace upper back teeth many times there is deficient bone in the area due to the loss of teeth or the patient’s own anatomy.
- Dr. Grimard will open up a small window of bone from the side of your sinus cavity. The membrane that lines the sinus cavity is gently elevated upwards and bone graft material is placed beneath it. We are never actually in the sinus cavity.
- Sometimes Dr. Grimard can place the implant at the same time as the Sinus Augmentation.
Vertical Sinus Augmentation
- Sometimes placing implants in the upper back tooth position it’s indicated that a slight amount of vertical bone height is required with implant placement,
- Vertical Sinus Augmentation gently raises the floor of the sinus with special instruments to add bone graft material and vertical height at the same time as dental implant placement.
Bone Grafting Around Teeth
- Sometimes periodontal disease will result in holes or depressions in the bone around teeth.
- After the teeth have been cleaned and sterilized a bone graft can be placed to fill in these holes and depressions.
- The purpose of a bone graft is to re-grow the lost bone around these diseased teeth, and gain back the missing support that was lost due to the periodontal disease.
- If this is indicated for your treatment Dr. Grimard will have a discussion with you regarding your different bone grafting options.
