Perio Plastic surgery

Question 1

plastic surgery
that concerns relations between
mucogingival tissues and attached gingiva,
alveolar mucosa, frenulum, muscle
attachment and vestibule.

Answer 1

Mucogingival surgery

Question 2

What are the 3 phenotypes of gingiva?

Answer 2

Thin scalloped
Thick scalloped
Thick flat

Question 3

• Apical shift of the gingival margin, associated
  with attachment loss
• Etiology-different conditions, pathologies
  – Toothbrush abrasion
  – Frenal attachment
  – Intrasulcular restorative margin placement*
  – Orthodontics-dependent upon direction and bucco-
  lingual soft tissue thickness

Answer 3

Recession

Question 4

If there are 3mm recession sites, what % increase in recession?

Answer 4

67%

Question 5

If there are 4mm recession sites, what % increase in recession

Answer 5

98%

Question 6

Miller classification:
–Marginal recession not extending to
the mucogingival junction
–No loss of interdental bone or soft
tissue
–100% root coverage possible

Answer 6

Class 1

Question 7

Miller classification:
–Marginal recession extends to or
beyond the mucogingival junction
–No loss of interdental bone or soft
tissue
–100% root coverage possible

Answer 7

Class 2

Question 8

Miller classification:

– Marginal tissue extends to or beyond the
mucogingival junction
– Loss of interdental bone and/or soft tissue
is apical to the CEJ, but coronal to most
apical extent of recession
– Partial but not total root coverage is
possible (50-70%)

Answer 8

• Class III

Question 9

Miller classification:

–Marginal tissue extends to or beyond
the mucogingival junction
–Loss of interdental tissue extends to
the apical extent of recession
–Root coverage cannot be anticipated

Answer 9

Class IV

Question 10

• Advantages
  – Root coverage on single or multiple teeth?
  – Abundant donor tissue available
• Disadvantages
  – Color**
  – Type of attachment?
  – Second surgical site

Answer 10

Autogenous gingival graft (Free gingival graft)

Question 11

What is the wound healing process around free gingival graft? 5 steps and what days?

Answer 11

– Plasmatic circulation (2-4 days)
– Revascularization (2-8 days)
– Organic Union (4-10 days)
– Epithelialization (10-14 days)
– Keratinization (21-180 days)
