Fig.3 shows the bite surfaces of three dentures.  The denture on the most left hand side is the old one with discoloration.  The one in the middle has just got a tooth (lateral incisor) back (>).  The denture on the most right hand side is supposed to be the exactly duplicated one to the one in the middle, but we have made a smart change.  One of the premolars (*) has been moved outside so that it is finally in the line of dental arch.  Anyway, the denture on the right hand side has more rounded and smooth arch outline.
