Soft Tissue Grafting Flashcards
Mucogingival Surgery definition
“Surgical procedures designed to preserve gingiva, remove aberrant frenulum or muscle attachment, and increase the depth of the vestibule”
Invovles the soft tissue - specifically the gingiva, frenum and vestibule
Periodontal Plastic Surgery definition
“Surgical procedures performed to prevent or correct anatomical, developmental, traumatical, or plaque-induced defects of the gingiva, alveolar mucosa, or bone”
Broad definition - related to hard tissues as well
How much gingival width is necessary to maintain periodontal health?
The width of the gingival has no impact on resistance to attachment loss
Periodontal health can be maintained independent of gingival width
Marginal Tissue Recession definition
The displacement of the soft tissue margin apical to the CEJ
Root coverage procedures definition
Surgical techniques designed to reduce the amount of root exposure
What are the Recession Classificaitons
Miller Classifications
Class I-IV
Miller Class I
Interproximal height is normal
Recession does not extend past the MGJ
Miller Class II
Interproximal height is normal
Recession extends past the MGJ
Miller Class III
Recession is present interproximally
‘Reasonable’ height discrepancy between the IP and the mid-facial
Miller Class IV
Recession present interproximally
The interproximal recession is close to or at the same level as the mid-facial recession
Recession incidence and extent increases with/in what/who?
Age
Males
African-Americans
On what surface is recession most often seen?
Buccal
If it is on the linguals, it is usually the anteriors
In younger patients, what teeth most commonly have recession?
Premolars
What are the different etiologies for recession?
Mechanical Trauma
Inflammation
Perio disease
What different types of mechanical trauma can cause recession?
Brushing and Flossing Improperly Self-inflicted (tooth-picks and fingers) Malocclusion Iatrogenic Oral piercings
What are some different iatrogenic examples that cause recession?
Appliances
Poorly fitting partials
What are some indications for Gingival Augmentation to resolve gingival recession?
- Patient discomfort while brushing or chewing because of lining mucosa
- Orthodontic tooth movement leading to bone dehiscence
- Subgingival restorations in thin tissue areas
What are the steps for Gingival Augmentation
1) Partial thickness bed
2) Harvest graft from the palate
3) Immobilize the graft
What should be the characteristics of the harvest for a Gingival Augmentation?
1.5-2.0mm thick
It should come from an area near the premolars
Which step in the Gingival Augmentation is most critical and why?
Immobilization
Because we are trying to reestablish the blood supply
T/F - Gingival Augmentation has a very predictable outcome
True
What are the steps for a Free Gingival Graft?
1) Split thickness bed
2) Use a surgical foil as a template
3) Harvest and place the graft
What are the accomplishments for a Free Gingival Graft?
Covered recession
Vestibule is deeper
Gingival thickness is better
Area is easier to maintain
What are the healing phases associated with a Free Gingival Graft?
Initial phase (0-3 days) Revascularization phase (2-11 days) Tissue maturation phase (11-42 days)
What are some characteristics of Free Gingival Graft Healing?
The bed has to be smooth
We don’t want a big clot (could cause dehiscence or necrosis)
We will slowly get anastomoses and more blood supply
