A Look At Grafting Materials For Dental Implants

Posted in News

Have you wondered about the materials used to craft dental implants? There are different types of dental bone grafts. The classifications for the graft materials are usually derived from the sources of bones used in the procedures such as are shown in the brief outline below.


Autogenous bone grafting – Autografts

Autografts are generally bone grafts that have been derived from the person’s body for purposes of doing dental implants. Autogenous bone grafts is often the initial option for dentists because autografts offer the most convenient result when compared with other implant grafting options. That is because the person’s bone marrow has the specific live cells required, which assist with continuous bone growth, speeding up the process of healing. The disadvantage of autogenous bone grafts is a secondary surgical location is needed; a site where bone grafts will be derived from.

Some of the popular sites to do this kind of harvesting include areas like the chin (or the back section of the jawbone). When larger quantities of bone graft is needed, the dental graft can also be obtained from body parts in other areas, particularly the hipbone. Hips are often considered a good source of bone graft because they contain lots of bone marrow that contains cells that readily form bone structures. When the dental grafts are derived from the chins the procedure is often performed under local anesthesia by the dentists in their dental office. If the dental implant bone graft is to be taken from other parts of the body, such as the hip, an orthopedic surgeon should perform the procedures.

Allogenous bone grafts – Allografts

These grafts are derived from someone else’s bones. They are usually stored in bone banks. These types grafts seek to provide other kinds of options for people who hope to skip the surgical procedures required to source for bone grafts or when larger blocks of bone structures are needed. Nevertheless, the patient should be ready to incur extra costs for sourcing them from bone banks. Allografts offer a lower performance compared with autografts, when it comes to bone regeneration. As a result, this treatment is expected to take much longer. Furthermore, allografts have a higher rate of failure than autografts.

The transmission of disease is often diminished by advanced technologies and tight screening protocol adhered the banks. One of the biggest advantages of this kind of bone graft is that there is a humongous supply of the alternative bone structures. Furthermore, the patients do not need two procedures to to complete the surgical process.


Bone grafts derived from species unrelated to human beings, particularly porcine (pig) or bovine (cow) origins are known as xenografts. The bone molecular structure is often similar across these species, making it possible to seek for an implant from other animal sources, with good results. The xenografts contain the sterilized non-organic materials of the animal’s bones. They are often utilized as scaffolds that tears down bone grafts, replacing it with bones that are simply natural.


Alloplasts seek to utilize synthetic materials to assist with bone formation. The grafts that have been made using synthetic material (hydroxyl apatite or calcium phosphate) work by mimicking natural bone to be formed by the body at the area of the implant. Synthetic materials often are utilized together with other growth mechanisms. Alternatively, it can be mixed together with the individual’s bone marrow for purposes of increasing biological activity. The alloplastic bone grafts offer less risks for infection compared with the autogenous bone grafts, although they are advanced as being less effective.

Growth Factor Enhancement Grafting

Growth Factor Enhancement Grafting (GFEG) is produced using DNA technology. As a result, these types of grafts are the most expensive types in the family of dental grafts. These grafts contain growth factors like Bone Morphogenic Proteins or the Platelet Derived Factor, together with carrier mediums, such as collagens. The GFEG have the ability of accelerating the process of bone formation.
