    (D) Shrinkage of the gums upon healing resulting in teeth appearing longer and greater spaces between some teeth.
  (7) Guided tissue regeneration-resorbable barrier.
    (A) Permanent or temporary numbness or altered sensation.
    (B) Accidental aspiration (into the lungs) of foreign matter.
    (C) Rejection of donor materials.
  (8) Guided tissue regeneration-nonresorbable barrier (includes membrane removal).
    (A) Permanent or temporary numbness or altered sensation.
