Term
What are 2 reasons for crown lengthening?
Give this one a try later!
Curette Efficacy: 3.73mm Restore biologic width
Instrument Limit: 5.52mm To establish a ferrule
, It is a 2 wall, vertical defect and
1 wall vertical defect the most common of the bony
defects
Don't know?
2 of 81
Term
Tarnow subclass C?
Give this one a try later!
Removal of nonsupporting bone. (If
you don't remove supporting
bone, but you reduce bone >7mm
thickness, then you are doing
osteoplasty)
Horizontal "through-and-through"
Pockets
destruciton of periodontal tissue in
furcation
Don't know?

Term
How many mm is the biologic width? what is it composed of?
,Give this one a try later!
1. Restore biologic 3mm. 2mm for DGJ, and 1 mm
width
for sulcus depth.
2. To establish a
ferrule
Ideal time is 90 days. (6-8 weeks if
gingival tissue is 3mm coronal to
you're in a rush, but the free gingival
the osseous crest
margin can move coronally up to 90
days after a procedure)
Don't know?

Term
5 Gingival augmentation indications?
Give this one a try later!
1. Thick bony ledge and exostosis
2.Early furcation invasion
3.Shallow and wide crater
1. Pliability (for ease of handling)
2.Knot security
3. Elasticity
4. Non-reactivity
5.Adequate tensile strength
6.Biodegradable
, 1. Prevent further attachment loss
2.Enhance plque control
3. Eliminate high frenum attachment
4. Ortho
5.Subgingival restorations
1. Friction forces during mastication
2.Retraction by muscles on gingival margins
3.Comfort and resistance to mechanical trauma during oral hygiene
4. Proper oral hygiene - mucosa is mobile and can retain food
Don't know?
5 of 81
Term
If a patient with delayed passive eruption on a tooth needs a crown
(on that same tooth) and therefore needs crown lengthening, what
is the first thing you should do to the tooth?
Give this one a try later!
1. Reduction of inflammation/pocket
2.Access to Root Surface
3.ScRP
4. Removal of Granulation Tissue
5.Combination Therapy (ex GTR)
Compare anatomic crown (measure of cej to incisal edge) with the clinical crown
(measure of gingival margin to incisal edge)
