Types of Implant(introduction)

There are a lot of implants that are available, and each of them is designed for a specific function. Most of them are made of titanium, which is an inert metal that has been proven to be effective at fusing with living bone, a process known as "osseointegration". The cylindrical or screw type of implant, that is called "root form", is similar in shape to the root of a tooth with a surface area designed to promote well attachment to the bone. This is the most commonly used design and generally placed where there is plentiful width and depth of jawbone. If the jawbone is too narrow or short for immediate placement of root form implants, the area can be enhanced with bone grafting to allow for their placement.

When the jawbone is not wide enough nor a good candidate for bone grafting, a special narrow implant, called "plate form", can be placed into the bone instead of first one. In cases of advanced bone loss, the "subperiosteal" implant, may be prescribed. It rests on the top of the bone, but under the gums.

The actual implant procedure involves the surgical placement of the implant or implants, a healing period and implant restoration to replace the missing tooth(or teeth). The treatment may be a cooperative effort between a surgical dentist who actually places the implant and a restorative dentist who designs, prescribes and inserts the final replacement teeth. Some dentists have advanced training and provide both of these services.

So, these three below are the main types of implants:
- The root implant
- The plate form implant
- The subperiosteal implant

From the next section, take a focus on each of types.
