Plastic Surgeries

Question 1

7 indications to treat recession

Answer 1

1. esthetics
2. progressive recession
3. thin biotype and planning for equal-gingival or sub-gingival restoration
4. root sensitivity
5. root caries
6. interference w/ OH
7. prevention before ortho

Question 2

what are the 5 flap options for recession

Answer 2

Coronally Advanced Flap (CAF)

Tunnel (no incision)

Lateral Sliding Flap (single tooth)

Double Papilla flap

Semilunar flap

Question 3

6 grafting options for recession

Answer 3

Subepithelial connective tissue graft (SGCT)

Allograft (human donor)

Mucograft (xenograft porcine collagen type 1 or 3)

Emdogain

Bone graft+ membrane (GTR)

Free Gingival graft (FGG)

Question 4

… plus … provides the best outcome for root coverage

Answer 4

CAF + SGCT

Question 5

what are 4 mechanical etiologies of gingival recession

Answer 5

traumatic brushing
ortho
trauma
parafunctional habit

Question 6

what are 3 biologic etiologies of recession

Answer 6

thin biotype
anatomy(tooth position)
defective restoration

Question 7

Miller classification … is when there is no interproximal bone loss and the recession does not extend to the mucogingival jxn.

100% root coverage can be anticipated in this classification

Answer 7

1

Question 8

Miller classification … is when there is no interproximal bone loss and the recession extends to or beyond the mucogingival junction

100% root coverage can be anticipated in this classification

Answer 8

2

Question 9

Miller classification … is when there is interproximal bone loss and the recession may or may not extend to the mucogingival junction

Only partial root coverage up the the level of the interproximal bone can be anticipated in this classification

Answer 9

3

Question 10

Miller classification … is when there is interproximal bone loss beyond the level of the recession

NO root coverage can be anticipated in this classification

Answer 10

4

Question 11

which grafting option is the gold standard and most predictable for treating recession?

Answer 11

subepithalial connective tissue graft (SGCT)

Question 12

3 indications for free gingival graft

Answer 12

increase KG/attached gingival

to increase vestibular depth

to achieve root coverage

Question 13

3 disadvantages of the free gingival graft

Answer 13

not predicatble to achieve root coverage

esthetic concern: color discrepancy

complications at donor site

Question 14

3 stages of healing for a free gingival graft

Answer 14

1. initial phase (0-3 days)- plasmatic circulation
2. revascularization phase (2-11 days)
3. tissue maturation phase (11-42 days)
