Dental implant is a replacement for the root or roots of a tooth. Dental implants are secured in the jawbone like tooth roots and are used to secure crown (the parts of teeth seen in the mouth), bridgework or dentures by a variety of means. They are made of titanium, which is lightweight, strong and biocompatible, which means that it is not rejected by the body. Titanium and titanium alloys are the most widely used metals in both dental and other bone implants, such as orthopedic joint replacements. Dental implants have the highest success rate of any implanted surgical device.
Dental implants have several advantages over conventional bridges for replacement of tooth
1. There is no preparation of adjacent teeth required for placement of implants.
2. Dental implants preserve the jaw bone into which they are placed. On the contrary, bone loss continues under the bridge in region of missing tooth which may lead to lead to further complications.
3. Dental implants are esthetically more pleasing.
