Pedicle Flaps Flashcards
What should you do if the papilla moves while you pull on the frenum?
Frenectomy
Describes the roots in gingival recession.
Denuded roots
This type of incisal relationship can cause gingival recession.
Traumatic incisal relationship
Trauma from what kinds of foreign bodies can cause gingival recession?
Piercings
How do the gingiva look when the teeth are out of alignment?
Have recession
Inflammatory causes of gingival recession.
- Periodontal disease
- Poor restorations (plaque traps)
- Ortho movement outside of the alveolar bone (loss of buccal bone and a decrease in gingival tissue thickness).
How do you calculate the width of attached gingiva?
(Keratinized width) - (Sulcular depth).
You want more of this type of gingiva in areas of fixed or removable prostheses.
Attached
In the absence of plaque, do you need attached gingiva to maintain health?
NO!
Does attached gingiva become wider or narrower as people age?
Wider
Does attached gingiva vary within the same person?
YES!
Where is the blood supply located for a pedicle flap?
At the base.
A flap which is attached to the original site by a narrow base of tissue to provide a blood supply during grafting.

Consequences of Gingival Recession
- Poor esthetics
- Hypersensitivity
- Wedge-shaped defects
- Plaque trap
- Root surface caries
Used to locate the MGJ
The “Roll” Test
Classification to determine extent of gingival recession
Miller Classification of Gingival Recession
What is the Miller Classification based on?
1) Length and width of gingival recession.
2) Relationship to the MGJ.
3) Presence/Absence of interproximal papillae.
4) Alveolar Bone loss.
What Miller class is this?
Recession that does not extend to the MGJ.
I
Complete root coverage is achievable.
What Miller class is this?
Recession that extends to or beyond the MGJ, with no periodontal attachment loss.
II
Complete root coverage is achievable.
What Miller class is this?
Recession that extends to or beyond the MCJ, with periodontal attachment loss in the interdental area or malpositioning of the teeth.
III
Only partial root coverage is possile to the height of the contour of the interproximal tissue.
What Miller class is this?
Gingival recession that extends to or beyond the MGJ, with severe bone or soft tissue loss in the interdental area and/or severe malpositioning of the teeth.
IV
Root coverage is unpredictable.
This type of graft is the gold standard for Miller Class I and II gingival recession.
