G. Mod. 19 Area-Specific Curets Flashcards
Area specific curet
Periodontal instrument used to remove light to moderate calculus deposits from crowns and roots of teeth
Unique design characteristics
Face, cutting edge, shank, tip, back, cross section
Face tilted in relation to lower shank (70* to shank)
-one cutting edge is lower on each working end
Only one cutting edge used per WE (lower)
Long complex functional shank that is especially suited for root surfaces
Rounded back, toe semicircular cross section
Cutting edges of area specific are
Curved
For enhanced adaptation
Which Working cutting edge is used
Lower cutting edge used
Non working cutting edge
Angled where
Other cutting edge not used
Angled away from soft tissue wall of pocket, helps protect tissue
Lower cutting edge is automatically at correct Angulation when
Lower cutting edge is the only one that needs to be
Lower shank is parallel to tooth surface
Only one that needs to be sharpened
Correct working end area specific for Anteriors
Hold instrument looking directly at toe of working end
Lower shank until perpendicular to floor
Lower cutting edge is working end
Anterior specific curet correct working end against tooth
Face is tilted toward tooth surface and partially hidden
Not same for surfaces toward and away
Lower shank= parallel to proximal surfaces (distal)
Functional shank= up and over tooth
Gracey 1/2
Anterior teeth
All surfaces
What/how many instruments are needed for instrumentation of posterior teeth
At least 2 double ended area specific instruments
Gracey curet
11/12
13/14
17/18
mesial facial and mesial lingual
line angle to distal
deeper pockets
Lower shank
Functional shank
Parallel
Up and over
To insert
Raise instruments handle and establish 0* Angulation
Return handle to correct position
Establish 80* angle in prep for calc removal strokes
