Implants are also a way of replacing a missing tooth or teeth. Dental implants are metal posts or frames surgically positioned into the jawbone beneath your gums to act as an anchor for replacement teeth. 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. The 3 parts to a Complete Dental Implant are the Dental implant, Abutment (or Post) and the Dental Crown. An abutment is made from either titanium or ceramic material and is a small 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.
