[英文釋義] Procedure of producing an imprint or negative likeness of the teeth and/or edentulous areas. Impressions are made in plastic material which becomes hardened or set while in contact with the tissue. They are later filled with plaster of Paris or artificial stone to produce a facsimile of the oral structures present. Impressions may be made of a full complement of teeth,of areas where some teeth have been removed,or in a mouth from which all teeth have been extracted. (Illustrated Dictionary of Dentistry,1982)
