Dental implants are the most natural way of replacing a missing tooth or teeth.  Implants are made from titanium alloy and resemble the root of a tooth.  These posts are placed into the jawbone and allowed to heal to the bone.  After the healing period, a crown or bridge is fabricated to replace the missing teeth.  Implants are also widely used to anchor dentures.  Although not appropriate in all cases, dental implants have become a reliable and mainstream dental treatment option.
