Perio plastic surg 2 Flashcards
What is the best way to prep a root surface before placin graft?
SRP
Should you prep root for graft before or after reflecting flap?
Before flap
- Advantages
– High predictability of root coverage
– Good color blend
– Smaller palatal wound site
– Double blood supply at graft site - Disadvantages
– Technical finesse to do procedure at
recipient and donor site
Connective tissue graft
Where is the thickest palatal tissue located?
Opposite premolars
- Advantages
–Superior esthetics and color blend
–“Flap” graft maintains blood supply
–No tension on flap
Disadvantages
-Requires 3-5 mm of keratinized gingiva
apical to area of recession
-Heals by secondary intention
-Needs underlying bone
Tarnow procedure (Semi-Lunar Coronally repositioned flap)
- Advantages
– Superior esthetics and color blend
– “Flap” (Pedicle) graft maintains blood supply
– No tension on flap - Disadvantages
– Requires adequate adjacent keratinized tissue
– Loss of 1-2 mm of attachment at donor
SRM2020
Lateral sliding flap (pedicle flap)
___ is done when there is adequate keratinized tissue on either side of the tooth you want to cover but not on the tooth you want to cover
Lateral sliding flap (pedicle flap)
____ is done when there enough keratinized tissue present but not in the right location
Tarnow procedure (Semi-Lunar Coronally repositioned flap)
- Resorption of ridge following extraction or
loss of teeth - Similar problems result from
– Developmental defects
– Advanced periodontal disease
– Excessive ridge resorption
