The document discusses several criteria for selecting artificial teeth, including size, color, form, and material. Size is determined by measuring dimensions of the mouth and residual ridge. Color should match the face and be selected from the manufacturer's shade guide. Form for anterior teeth follows facial shape and outlines, while posterior teeth come in anatomic, semi-anatomic, and non-anatomic styles. Material options include porcelain, acrylic, and acrylic with metal; each has advantages and disadvantages related to esthetics, function, and maintenance.
