Missing teeth over a period of time can cause your jawbone to atrophy, or resorb. This often results in poor quality and quantity of bone suitable for the placement of dental implants as well as long term shifting of remaining teeth and changes to facial structure. Most patients, in these situations, are not candidates for dental implants.
Fortunately, today we have the ability to grow bone where it is needed. This not only gives us the opportunity to place implants of proper length and width, but it also gives us a chance to restore functionality and aesthetic appearance.
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease, or injuries. The bone is obtained from a bone bank. Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum to protect the bone graft, as well as encourage bone regeneration. This is called guided bone regeneration, or guided tissue regeneration.
Bone Graft Products
This product is an allograft, which consists of cancellous bone particles. These particles and sterilized, processed and monitored. Patients who have extractions done and are considering implants may require a socket preservation in which Puros is used.
Bone loss limits the ability to successfully place dental implants and/or partial dentures due to the absence of sufficient bony volume in the upper or lower jaw. Puros helps your body naturally rebuild bone where you need it.
Puros cancellous particles provide an exceptional matrix for blood and cells. It is cancellous particulate allograft and has been used in dental applications with reliable and predictable clinical results. It has become the product of choice for many surgeons due to its history of complete, rapid and effective bone regeneration. It effectively remodels, leaving behind healthy, natural bone. Puros cancellous particulate allografts have shown successful results in:
- Reconstruction of the ridge for prosthetic therapy
- Filling of osseous defects, such as extraction socket
- Repair of infrabony periodontal defects
Regenaform is an allograft which contains human demineralized bone matrix and cortical cancellous chips in a porcine gelatin carrier. This product is used to induce bone formation. Dr. Khanuja would typically use this graft in regenerative sites the necessitate augmentation to help increase the bone width for future implant placement. Healing time for bone to regenerate usually take 6 months before implants can be placed. This surgery is called a ridge augmentation.
The Collaplug collagen wound dressings is a soft, white, pliable, nonfriable sponge used in dental surgery. Because of the coherent sponge structure, application of the dressings to the wound is easily controlled. It can be used for extraction sites when bone graft is placed for socket preservation to protect the graft material during the healing process. They are designed to resorb in 10-14 days.
Geistlich Bio-Gide® is a naturally resorbable non cross-linked collagen membrane has that has properties built into its bilayer structure that support bone and periodontal regeneration underneath as well as soft tissue healing over the barrier. Dr. Khanuja uses Bio-Gide for procedures such as ridge augmentation and sinus lifts.
