Dental Implant Bone Grafts
What is Dental Implant Bone Grafting?
Dental implant bone grafting is a surgical procedure performed to replace missing bone with a bone graft and help the body regrow new bone in implantation areas with severe bone loss. Bone grafting is usually part of a bone augmentation process that could also involve Guided Bone Regeneration (GBR).
Who can benefit from dental implant bone grafts?
A dental implant bone graft can benefit patients with severe jaw bone loss who are not suitable candidates for dental implants for this reason.
Providing adequate mass of jaw bone is essential for the success of a dental implant. Lack of sufficient bone may lead to osseointegration problems and implant failure.
Bone grafts can also be used for the treatment of periodontal disease in order to repair the damaged bone tissue and protect the existing teeth by providing better support.
Dental implant bone grafting involves a surgical procedure for the placement of the bone graft, followed from a period of several months until the grafted material fuses with the existing bone through the stimulation of new bone growth.
Why you may need dental bone grafting?
A dental implant bone graft is necessary when there is not enough jawbone structure to support the placement of one or more implants and provide sufficient strength and stability. The success of dental implants depends significantly on the existence of adequate jaw bone around the implant. The bonding of the implant to the jaw can be succeeded only when there is a critical mass of healthy jawbone to trigger and maintain the osseointegration process.
Many patients who want to replace missing teeth with dental implants learn from their dentists that they are not suitable candidates for dental implants due to the poor condition of the bone in their jaws. Without a procedure such as bone graft their only alternative are conventional bridges or dentures. Dental implant bone grafting can restore the lost bone and allow them to have new completely functional teeth with dental implants.
Bone graft procedures are performed usually to correct existing bone loss problems in preparation of dental implant placement. Some times the dentist will perform a bone graft immediately after a tooth extraction to fill the extraction site and prevent the bone loss around it.
Replacement of missing bone structure with dental implant bone graft can be the critical factor between implant success and implant failure. Researches indicate that bone grafting can reduce the risk of implant complications.
Conditions leading to need a bone graft
Dental implant bone graft is required when the jawbone is missing the adequate width or height to allow the successful placement of dental implants.
Jaw bone loss is in most cases caused either due to missing teeth or because of severe periodontal disease. In general, you may need dental bone grafting in case of:
- missing teeth - Bone maintains its structure and volume through mechanical stimuli. When a tooth is lost, the mechanical stimulus is also lost; the body thinks that the bone is no longer needed there and starts the resorption process to recover the bone minerals. This condition can lead to poor quality and quantity of bone making patients not suitable candidates for placement of dental implants. People who have been edentulous (without teeth) for a prolonged period are the more seriously affected.
- periodontal disease - Infections of the periodontium trigger a response from the body's immune system. Specialized cells called phagocytes attack the infected tissues, gums, periodontal ligament and jawbone, in an effort to eliminate the infection. The process can lead to severe loss of jaw bone structure if the periodontal disease is not treated successfully. Not only existing teeth may be lost but the ability of replacing them with dental implants is also decreased.
- injury - Other conditions that dental implant bone grafts are needed include injury or trauma and some developmental defects that affect the bone growth pattern. Removal of cysts or tumors may also cause bone defects that require bone grafting.
Dental implant bone grafts give us the opportunity to restore the jawbone to the appropriate length and width so that dental implants can be placed.
