Bone Grafting for Dental Implants

To receive dental implants, it’s important to ensure your gums and bone structure is strong enough to support them. When you lose a tooth, the bone beneath has nothing to push against, causing it to weaken. If your jaw is too soft or thin due to tooth loss, gum disease, cavities, infections or injury, you may not have a suitable base for the dental implants. In cases such as this, bone grafts can create a stronger foundation for the implants by transplanting new bone into your jaw. A routine procedure often recommended when a patient has extensive tooth decay or a traumatic dental injury, bone grafting is designed to add bone mass to your jaw, replacing insufficient or missing bone.
A bone graft is only required if you don’t have enough bone in your jaw to support the dental implants. At Tooth Crusader, our dentists will assess the structure of your jaw to determine if this will be a necessary procedure. For more information, call our team today on (02) 8097 1838.

Types of Bone Graft

Depending on what reason you need a bone graft, whether it’s soft tissue or not enough space in your jaw, there are several types of bone grafts available. The most common is the socket graft the purpose of which is to protect the alveolar bone to prevent further deterioration. A block bone graft is used when a major injury or trauma has caused defects in your jaw. The block bone graft takes bone from the back of your jaw and holds it in place with titanium screws until the new bone tissue fuses. A lateral ride preservation graft is used when a patient’s jaw is not wide enough and a sinus lift procedure is often used for dental implants on the upper jaw.

Bone Graft Tissue & Material Sources

Bone Graft Tissue & Material Sources
There are several different options as to where you can get the tissue or material that will become your bone graft. They all work differently and our dentists at Tooth Crusader can help determine which is best for you.

Xenograft tissue – taken from an animal source
The benefits of using a xenograft tissue is that it is readily available and has well documented success. Although it is commonly used in surgery, there is a low risk of disease transmission and may not stimulate your body’s cells to form new bone.

Alloplast bone graft – synthetic material
The advantages and downfalls of synthetic material for a bone graft is much the same as a xenograft. There is well documented success, it is readily available and is commonly used in surgery, however, it does not stimulate your body’s cell to form bone and is limited in its ability to heal large defects.

Autograft tissue – bone surgically taken from elsewhere on your body
One of the most common options for a bone graft, the autograft offers no potential for disease transmission or immune reaction. While it offers the possibility of healing large and small defects it may not be an option for everyone and additional surgery is required.

 

Allograft tissue – donated from a human cadaver
With minimal risk for disease transmission and the potential to heal small defects, allograft is another commonly used process. Portions of the graft may turn into your own bone, however, it does not stimulate your body’s cells to form new bone.

Growth factors – synthetic protein from your body
If you like the idea of your graft coming from your own body but don’t want the additional surgery to remove some bone tissue, growth factors are an ideal second option. A relatively new technology, growth factors have proven, predictable growth results but are not suitable for pregnant women or those who plan to become pregnant in the next 12 months or are currently nursing. Additionally, you must be over 18 years of age and should not be used in people with immune deficiencies.

It’s important to note that as the natural bone grows, it will naturally replace the graft material resulting in a fully regenerated jaw. If you have any questions or concerns about the bone graft procedure, call our team at Tooth Crusader today on (02) 8097 1838.
