A Bone of Contention: Do Dental Implants Require You to Have Bone Grafts?
Dental implants are the closest thing to a natural tooth available today. One of their most amazing attributes is that they stimulate bone growth. This growth helps to hold the dental implants in place, in a somewhat similar manner to natural teeth. The biggest difference is that dental implants are composed of titanium and porcelain.
However, although dental implants will encourage bone growth once placed in a jawbone, they cannot be placed in areas of low bone density.
