A natural tooth consists of a root and a crown. If you compare natural teeth to implant-supported replacement teeth, you’ll see they have the same basic parts. Both have a crown (the visible part used for chew food). Both have a root that holds the tooth securely under the gum and is anchored in the jaw. The difference is that the implant is made of titanium, the element used extensively for artificial joint surgery. When you loose a tooth, you loose both the root and the crown. The implant is surgically placed into the jawbone where teeth are missing. This metal anchor acts as a tooth root substitute. The jawbone fuses with the implant, creating a secure platform for the prosthesis.
