Fig. 9 Upper left half of dental arch Note regularization of tissues from the palatal side Fig. 10 Lower right half of dental arch: the angle of the lancet is much less accentuated because we have here a smaller amount of adhering gum. Festooning and chamfering will be performed following removal of the altered tissues by carrying out careful gingival plastics.
