Dental implants are titanium materials embedded in bone to support all types of permanent dentures, especially fixed dentures such as crowns or bridges, or to anchor removable dentures at the gum base and flat bone. This makes removable dentures more secure and stable than removable dentures without implants, which, when placed on a thin gum base, may become loose, wobbly, and hinder chewing. They may even fall out while speaking or laughing. Implants are firmly anchored in bone, providing stable, natural feeling teeth.
