Today, most dental implants are made of titanium. This metal has special qualities that make it useful for implants.Titanium develops a thin film on its surface that protects it from corrosion. It is resistant to acids, salt solutions and oxygen, among other things. Titanium also is almost completely nonmagnetic. It is extremely strong for its weight.Perhaps most important, the body does not reject titanium implants as foreign objects.
There are several types of implants. Your dentist decides which type of implant to use based on certain criteria.
Root-Form Implant
Root-form implants are called endosseous or endosteal implants. This means that they are placed in the bone.
Sub-periosteal Implant
The subperiosteal implant is a custom-made metal frame that sits precisely on top of the bone, but under the gums.
Mini-Implant
These small implants are usually about 2 millimeters in diameter. This is almost half the size of many traditional root-form implants.They are placed in the same way as larger root-form implants.
