The SR Vivodent^® S DCL shade guide enables the operator to determine the tooth shade according to the A-D or Bleach shade system. The shade guide includes an integrated facial meter and papillameter to easily determine the tooth size. The facial meter is used to measure the interalar width of the nose and select the appropriate tooth size. The Papillameter is the ideal device for the definition of the length of the upper lip and the lip closure line.
