Mucogingival Surgery Part 1 and 2 Flashcards
what is mucogingival surgery
plastic surgery that concerns relations between mucogingival tissues and attached gingiva, alveolar mucosa, frenulum, muscle attachment and vestibule
what are mucogingival conditions
deviations from the normal anatomic relationship between the gingival margin and MGJ
what are the clinical features of mucogingival conditions
- recession, absence or reduction of keratinized tissue, and probing depths extending beyond the MGJ
- anatomical variations conditions include tooth position, frenulum insertions and vestibular depth
- variations in ridge anatomy may be associated with mucogingival conditions
how much keratinized tissue is considered normal
1-9mm
what cases would you need to provide a more esthetically acceptable gingival form and contour
- localized gingival recession
- localized alveolar ridge deficiency
- excessive gingival display
- gingival enlargement or asymmetrry
what is the definition of recession
- apical shift of the gingival margin, associated with attachment loss
what are the etiologies of recession
- toothbrush abrasion
- frenal attachment
- intrasulcular restorative margin placement
- orthodontics- dependent upon direction and bucco-lingual soft tissue thickness
exposed root surfaces makes it potentially more susceptible to:
- root caries
- non carious cervical lesions
- dentinal sensitivity
- poor esthetics
what are the predisposing factors for localized gingival recession
- inadequate attached gingiva
- malposed teeth
- TB habit
- chronic inflammation
- iatrogenic
- factitious
- frenulum attachment
- eruption pattern
- smokeless tobacco
- substance abuse- cocaine
- orthodontics
inadequate attached gingiva is:
a dimension not a measurement - width and thickness
what are the treatment objectives for localized gingival recession
- root coverage
- increase the width and thickness of keratinized tissue
what are the indications for root coverage
- esthetic concern
- dentinal sensitivity
what are the indications for the width of keratinized tissue
- control of plaque/inflammation
- prevent further recession
patients in their 40s with recession, ____ have an area of 3mm of recession

patients in their 80s with recession, ____ have an area of 3mm of recession
60%
3mm of recession sites had ____ of sites increase in recession
67%
4mm of recession sites had ____of sites increase in recession
98%
what is class I recession
- marginal recession not extending to the MGJ
- no loss of interdental bone or soft tissue
- 100% root coverage possible
what is a class II recession
- marginal recession extends to or beyond the MGJ
- no loss of interdental bone or soft tissue
- 100% root coverage possible
