What is a bone graft and what’s its purpose
Bone graft is a substitute bone used to restore and preserve your jawbone. Bone graft is primarily used during tooth extraction for socket preservation. Placing bone graft after tooth extraction assists your body in growing more of its own bone. Essentially, bone graft acts as a space maintainer by filling in the tooth extraction site. This allows your body to regenerate new bone at a better rate which results in more bone regeneration. Talk to your dentist to learn more about bone grafting and other bone augmentation procedures.
Bone graft assists your body in healing better after tooth extraction and helps preserve more of your jawbone. Whenever you lose a tooth, your jawbone starts to shrink at an accelerated rate. Placing a bone graft after tooth extraction helps preserve your jawbone. This is especially important if you’re planning on placing a dental implant in place of the missing tooth. In order for dental implants to be successful, they must be placed in solid bone structure. Often times, the ideal spot for placing a dental implant lacks sufficient bone to fully secure the implant post in place. In these situations, your dentist has to add bone graft to prepare your jawbone for implant placement.
There are many different sources for bone grafting materials. Each type of bone graft has its own implications and uses. Here’s a list of the some of the most common types of bone grafting materials used in implant dentistry:
Synthetic bone graft
Synthetic bone grafts are the most commonly used type of grafting material. These are made from material which resembles bone particles, such as calcium apatite or calcium phosphate. The purpose of synthetic bone graft is to fill in smaller defects to allow for more bone growth within the region.
Allograft is any type of bone graft which comes from cadaver or animal donor sites. This includes bovine bone (from cows), xenograft bone (from pigs), as well as human cadaver bone. Allograft bone doesn’t get absorbed as quickly as synthetic bone does. This makes allograft a better option for preserving larger bony defects where you want the bone graft to last for a longer period of time.
Autogenous bone graft
Autogenous bone graft is any bone graft that comes from your own body. Your implant dentist or oral surgeon will harvest bone from a donor site in your body and use it to repair another site. Common donor sites include the mandible ramus and the chin area. For the most complicated cases, your dentist may harvest bone from your rib cages. Autogenous bone grafting is typically reserved for repairing the most extensive bony defects when there are no alternatives.
Bone grafts help your body regenerate more of its own natural bone. They essentially act as a space holder to permit your bone to grow into the graft region. As you deposit more bone tissue, your body gradually absorbs and replaces the majority of your bone graft with natural bone. Once you develop enough solid bone, your dentist can now secure your dental implant(s) in place and restore your missing teeth.

A sinus lift or graft is performed whenever there’s insufficient bone to place dental implants in the upper posterior region. For those of you with a knowledge of teeth numbers, this includes teeth #2, 3, 4, 13, 14, 15 and less commonly teeth #5 and 12. The upper posterior jaws typically lack sufficient bone for implant placement. This is due to the proximity of the maxillary sinuses which often times creates a challenge to placing dental implants. In order to restore enough bone for implant placement, a sinus lift or sinus graft must be performed. Here’s a bit more information about what these sinus surgeries involve:
You require a sinus lift whenever there’s between 5 to 8 millimetres of jawbone under the sinus membranes. This is not enough bone to secure a dental implant and your dentist needs to push the sinus membrane up in order to place the implant posts. Your dentist will gently push and lift your sinus membrane upwards and pack bone underneath it. This creates the additional room required to place a large enough dental implant to restore your missing teeth. Often times, the dental implant and sinus lift area performed at the same time during one surgery.
Lateral wall sinus graft
A lateral wall sinus graft is required whenever there is almost no bone under your sinus membranes. Typically, you require a lateral wall sinus graft whenever there is less than 3 to 4 millimetres of bone under the sinuses. A sinus lift alone can not restore sufficient bone for implant placement under these circumstances. Instead, you must perform a lateral wall sinus graft. First, your dentist will create an opening in your upper jaw using a lateral wall approach. Next, your dentist will gently separate and lift your sinus membrane. Through this opening your dentist will add a significant amount of bone grafting material to prepare the area for implant placement. You must avoid putting pressure on your sinuses for the following few weeks. It typically takes several months for the sinus to grow sufficient bone and you are now ready to place your dental implants under the sinuses.
Grafting procedures are required whenever there’s not enough jawbone to place dental implants. Your dentist will start by examining your jawbone using X-rays and CT scans. If you have sufficient jawbone, then your dentist can proceed with dental implant surgery. However, if you don’t have enough bone structure, then a grafting procedure may be necessary. The type of grafting procedure depends on the where the implants are being placed, and how much original bone structure you currently have. Schedule your consultation with an implant dentist near you to see if you’re a good candidate for dental implant treatment today.
