Surgery is indicated when the pocket formation exceeds the ability
of the body to eliminate the sulcar pathogens on a daily basis,
to prevent progression of pocket depth.
Notes
-
There can be bone loss without pocket formation, where the
gingiva follows the bone and maintains the normal anatomy. Surgery
is not indicated here
-
A minimum of 1.5mm to 2mm attached gingiva must remain to protect
alveolar bone.
