A removable denture replaces lost teeth and gum tissue. Partials are utilized when one or more of the natural teeth still exist. They are often made up of new teeth linked to a plastic base, which helps the remaining teeth stay in their current position. Complete dentures include both conventional and instant dentures. Traditional implants are inserted approximately 12 weeks after the natural teeth have been extracted and the gums have healed. Immediate implants are placed immediately following the extraction of the natural teeth.
