Mucogingival Surgery Flashcards
(26 cards)
what patient factors are important for surgery
oral hygiene
quality of maintenance available and patient access
ability of patient to tolerate procedure
compliance
aesthetics
what are the tooth factors important for surgery
access to non-responding sites
shape of defect
prosthodontic/endo
tooth position/anatomy
what medical factors are important for surgery
smoking
cardiac issues
poorly controlled diabetes
immunosuppressed
anticoagulants
what are the 3 surgical approaches
conservative (access)
resective
reconstructive
what factors determine which surgery approach you get
anatomy of residual pocket
anatomy of tooth
position of tooth
complexity and predictability
what is regenerative surgery
promote regeneration of periodontal tissues that have been lost
uses membranes/grafts
what are the indications for mucogingival surgery
periodontitis lesions
mucogingival deformities
short clinical crowns
removal or aberrant frena
pre-implant surgery
what are the 3 most common mucogingival surgery procedures (grafts)
free gingival graft
pedicle graft
connective tissue graft
what is the difference between a split and full thickness flap
full thickness raises the periosteum as well but split does not
what is a free gingival graft
raise a split thickness flap and place graft onto the exposed connective tissue allowing healing
what is a connective tissue graft
open up a window and remove connective tissue and then close over the epithelium so no open wound
what are the 3 classifications of infrabony defects
one wall defects
two wall defects
three wall defects
what biomaterials can be used in surgery
barrier membrane
DBBM
EMD
how do access and resective surgeries heal
long junctional epithelium
how do graft surgeries heal
new connective tissue attachments
what is gingival recession
apical migration of gingival margin from CEJ
what are the indications for treatment with gingival recession
poor aesthetics
difficult plaque control
sensitivity
what is the aetiology of localised recession
excessive toothbrushing
traumatic incisor relationship
habits
anatomical
what is the aetiology of generalised recession
ongoing periodontal disease or following resolution of inflammation after successful treatment
what classification is used for gingival recession
cairo
what is the cairo classification
- no interproximal tissue loss
- interproximal loss but not as bad as mid-buccal
- interproximal loss worse than mid-buccal
what are the treatment options for gingival recession
record magnitude
eliminate aetiological factors
oral hygiene instruction
topical desensitising agents
gingival veneer
crowns
mucogingival surgery
what does crown lengthening aim to do
apically reposition the entire periodontal attachment including alveolar bone
what are the indications for crown lengthening
retention for restorations
for ferrule
subgingival pathology
correct uneven gingival contour
