Dental implant. Illustration of a cross-section through a jawbone showing the fitting of a dental implant. First the metal post (at lower centre) is surgically embedded in a drilled hole in the jawbone (yellow). Then attachments (at centre) that protrude above the gum (pink) are screwed into place. Finally the false tooth (at upper centre) is cemented on. The type of material used to make the false tooth varies according to the properties of the tooth it is replacing. Dental implants are used when the patient has lost so much tooth-bearing tissue that dentures would not remain in place.
