Exam 2 - Periodontal Esthetic Surgery Flashcards
Mucogingival surgery is now referred to as what?
Periodontal plastic surgery
Define Periodontal plastic surgery
Surgical procedures performed to correct or eliminate anatomic, developmental, or traumatic deformities of the gingiva or alveolar mucosa
The purpose of the Pushback Procedure
Used to eliminate periodontal pockets and establish a wider band of keratinized and attached gingiva
For what 5 reasons is the pushback procedure not necessarily a good procedure
- Exposure of denuded bone during healing
- Resorption of crestal bone
- “Stormy” post-surgery healing phase.
- Poor esthetic results
- Poor long-term results if infra bony lesions (vertical bone defects) are not adequately treated.
How much attached keratinized mucosa is necessary for maintaining health?
2 mm at least
Name 6 etiologies of recession
- Plaque
- Plaque/calculus
- Trauma
- Malposed tooth
- Plaque/Frenulum
- Toothbrushing
T or F, Width of Keratinized tissue - PD = Attached gingiva
True
T or F, Keratinized tissue is always attached
False, Not always!
Bony dehiscence combined with thin biotype may result in what?
Tissue fenestration and recession
Reasons for Treatment of Gingival Recession Defects:
- Increasing width of Keratinized and attached gingiva
2. For root coverage
What concerns cause us to increase the width of keratinized and attached gingiva?
- Prosthetic concerns
- Orthodontic concerns
- Prevent progressive recession
What concerns do we have causing us to treat gingival recession for root coverage?
- Esthetic concerns
- Dentinal Sensitivity
- Prevention of root caries
3 treatment options for increasing the width of attached gingiva?
- Apically positioned flap (APF)
- Full thickness flap - Free autogenous gingival graft (FGG)
- Subepithelial connective tissue graft (CTG)
3 treatment options for obtaining root coverage
- Subepithelial connective tissue graft (CTG)
- Semi-lunar incision + coronal positioning (Tarnow procedure)
- Lateral pedicle flat (LPF)
5 factors to consider in determining where to position the apically positioned flap
- Initial width and thickness of the gingiva
- Thickness of the marginal alveolar bone
- Amount of pocket reduction required
- Length of the root trunk (average is 3 mm)
- Clinical crown length required for restorative or prosthetic treatment and esthetics
