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 to chew food), and both have a root that anchors the crown to the bone. The difference is that the dental implant is made of titanium – the same time-tested material used by surgeons for artificial joints. When you lose a tooth, you lose both the root and the crown. To replace the tooth, you need to replace both the root with the dental implant AND the crown. Dr. Filippi is a dental surgeon who specializes in the replacement of the root via the placement of the dental implant. Your dental is the expert is replacing the crown.
