flap op

Question 1

what is a surgical flap

Answer 1

seperation of tissue from surrounding tissues except for its base
in perio: we use flap to remove soft tissue and reach periodontal structures

Question 2

flap according to thickness

Answer 2

full thickness (mucoperiostal)

• epithelium
• connective tissue
• periosteoum
• most commen when bone resection or regeneration

partial thickness (split thickness-mucosal)

• periosteoum not included
• in mucogingival surgeries to leave blood supply

*a combination might b used 4 crown lenght n some mucogingival procedures

Question 3

flaps acc 2 position

Answer 3

simple flap
apicallly repos.
coronally
laterally

Question 4

flap indications

Answer 4

• accesibility 4 root planing
• establish the morphology of area easy 2 clean n with less plaque retention
• correction of gingival overgrowth
• shifting gingival margin apically for plaque retaining restorations
• pocket depth reduction! (apically repos)
• thickening of marginal bone

Question 5

flap contraind

Answer 5

poor patient coop
poor plaque control
high caries rate
uncontrolled medical conditions
-diabetes
-hypertension
-blood disorders
-unstable angina
-myocard inf within 6 m

Question 6

advantages over curetage or gingivectomy

Answer 6

direct vision 4 optimum s & r p
little periodontal tissue loss
pocket epithelium entirely removed
no defects on bones coverd by flaps
no open wounds persist post op

disad: when flaps r repositioned apically: hypersensitivity n poor aesthetic

Question 7

stages of flap op

Answer 7

1 local anesthesia 
2 incision
3 flap reflection
4 removal of granulation tissues
5 scaling n root planing
6 osseous recountouring resection or regeneration
7 position of flap
8 suturing
9 post op care
