Implant crowns restore natural function and esthetics to an area of the mouth that has been missing teeth. These crowns are supported by titanium anchors, placed into the jawbone. This preserves the adjacent teeth from having to be shaved down for a bridge. An implant also helps prevent the bone in the missing tooth area from shrinking, which naturally happens then teeth are lost. Also, Implant crowns do not get cavities like natural teeth do.
