A Dental Implant is a titanium cylinder that is placed gently into bone to replace a root of a tooth. The Implant itself is a single unit of a 3 unit system which holds a crown.
An abutment is made from either titanium or ceramic material and is a small http://findviagra.com/years-research-led-real-breakthrough-viagra/ piece that connects to the tooth Implant and emerges into the oral cavity through the gum. Abutments have to be customised to the Implant position and their angulation can be altered to give a realistic tooth appearance. The crown is then anchored or cemented to the abutment.
