Q

For what 5 reasons is the pushback procedure not necessarily a good procedure

A
  1. Exposure of denuded bone during healing
  2. Resorption of crestal bone
  3. “Stormy” post-surgery healing phase.
  4. Poor esthetic results
  5. Poor long-term results if infra bony lesions (vertical bone defects) are not adequately treated.

Q

3 treatment options for increasing the width of attached gingiva?

A

Q

5 factors to consider in determining where to position the apically positioned flap

A
  1. Initial width and thickness of the gingiva
  2. Thickness of the marginal alveolar bone
  3. Amount of pocket reduction required
  4. Length of the root trunk (average is 3 mm)
  5. Clinical crown length required for restorative or prosthetic treatment and esthetics

Q

5 indications of the Free Autogenous Gingival Graft (FGG)

A
  1. Increase width of attached gingiva
  2. Removed abnormal frenulum attachment
  3. Deepen oral vestibule
  4. Ridge augmentation procedures
  5. Cover exposed roots
    • The FGG is rarely used for this purpose
17
Q

3 advantages of the FGG procedure

A
  1. Not technically demanding
  2. May be accomplished with partial or full-thickness flap reflections
  3. Wide variety of clinical applications
18
Q

4 disadvantages of the FGG procedure

A
  1. Poor ability to provide blood supply to graft for root coverage
  2. Esthetic results are compromised due to scarring during healing resulting in poor color match
  3. Surgery required at two intraoral sites
  4. Donor site may present problems with bleeding, pain, and slow healing
19
Q

5 indications of the Subepithelial Connective Tissue Graft (CTG)

A
  1. Acquire a width of attached gingiva
  2. Deepen the oral vestibule
  3. Remove frenulum and muscle attachment
  4. Acquire esthetic attached gingiva (color match)
  5. Cover exposed root surface
20
Q

5 advantages of the CTG procedure

A
  1. High predictability
  2. Graft receives abundant blood supply
  3. Palatal wound (donor site) can be surgically closed, thereby facilitating rapid healing with little to no discomfort or bleeding
  4. Good color match
  5. Applicable for recession on multiple teeth
21
Q

2 Disadvantages of the CTG

A
  1. Technically demanding

2. Gingivoplasty may be necessary after healing to obtain better tissue contours and to decrease thickness

22
Q

2 indications of Semi-lunar incision with coronal positioning (Tarnow procedure)

A
  1. Maxillary anterior teeth with no more than 2 mm of recession and 3-5 mm of remaining keratinized gingiva
  2. A complimentary procedure for small areas of gingival recession remaining after other procedures were used for root coverage
23
Q

7 advantages to the Semi-lunar incision with coronal positioning (Tarnow procedure)

A
  1. No tension on coronal positioned flap
  2. No narrowing of the oral vestibule
  3. Good esthetics due to color match
  4. Papillary height is preserved
  5. Simple surgical procedure
  6. Minimal post-operative discomfort
  7. Applicable to minimal gingival recession across multiple teeth
24
Q

5 Disadvantages to the turnoff procedure

A
  1. Not applicable in cases of moderate to advanced gingival recession (greater than 2mm)
  2. Requires 3-5 mm of thick keratinized tissue
  3. Healing is by secondary intention and therefore some contraction may occur
  4. May require a second procedure, depending on occurrence of tissue contraction
  5. Where osseous dehiscence or fenestration exists apical to the gingival recession area, a FGG or CTG should be performed after coronal positioning of the semi-lunar flap
