Q

What are the basic characteristics of this instrument?

Study These Flashcards
A

Sickle scaler

triangular shape

double cutting edge

pointed tip

used supragingival with pulling stroke

22
Q

Name the curette type, as seen from the toe

Study These Flashcards
A

A= Universal Curette; blade is 90 degree angle to the lower shank

B= Gracey Curette; blade is 70 degree angle from the lower shank

23
Q

Describe the gracey curette

24
Q

What are these different Gracey designs?

Study These Flashcards
A

Standard, After 5, Mini-Five, Micro Mini-Five

(all #1-2)

After 5 has a 3mm longer terminal shank

The Mini and Micro Mini have shorter blades to allow increased access and less tissue trauma

25
What is this a depiction of?
The Gracey _Curvette blade_ compared to the Gracey Curette. The blade is 50% shorter with upward curve. Allows closer adaptation but risks gouging/grooves in tooth surface.
26
How do you determine the correct cutting edge of the Gracey curette?
When viewed from directly above the face of the blade, the correct cutting edge is the one forming the _larger outer curve_.
27
What is the 2-point contact used for dental hoe?
28
What are these and their use?
Diamond files for final finishing of root surfaces
29
What are these and what is their use?
Quetin curettes; hoes with shallow half-moon radius used for the roof or floor of a furcation
30
What are these?
Metal prophy angle with rubber cup and brush
31
Which is the correcct blade angulation for scaling and root planing?
B- 45 to 90 degrees. A is correct for blade insertion= 0 degrees D is correct for gingival curettage (\>90 degrees)
32
What is depicted here?
Subgingival scaling A- curette is inserted w blade flush against tooth B- working angulation established 45-90 degrees C- lateral pressure applied and scaling stroke in coronal direction
33
What is the cutting edge?
Cutting edge of a curette is formed by the angular junction of the face and lateral surface of the instrument. When sharp, the edge is a fine line.
34
Name the sharpening stones
Top to bottom: Flat India stone Arkansas Stone Cone-shaped Arkansas stone Ceramic Stone Flat, 1-sided diamond sharpening cards (Extra fine, fine & medium grit)
35
What is the correct sharpening angle to maintain the cutting edge of a sickle scaler or curette?
The sharpening stone forms a 100 to 110-degree angle with the face of the instrument. This preserves the 70-80 degree angle between the face and lateral surface.
36
What is the angle for sharpening a chisel?
When the entire bevel contacts the stone, the angle between the instrument and stone is 45 degrees. The cutting edge will be maintained if this angle is used and the instrument pushed along the stone.
37
How does the sonic scaler tip travel?
In an elliptical or orbital pattern with frequency 2000-6500 cycles/sec.
38
How does a magnetostrictive ultrasonic device work?
Operates at 18000-50000 cycles per sec Uses metal stacks that change direction as electricity is applied Tip works in an elliptical or orbital pattern 4 working surfaces
39
How many working surfaces does the piezoelectric scaler tip have? Pattern? Frequency?
2 surfaces, linear pattern, 18K-50K cycles/sec
40
Name the instrument?
Kirkland gingivectomy knife
41
Name the instrument
Orban interdental knife
42
Name the instrument Distinguishing feature?
Pritchard surgical curette Surgical curettes have wider blades than those used for scaling and root planing.
43
Name the instrument
back action surgical chisel
44
Name the instrument
Woodson periosteal elevator
45
Name the instruments
Ochsenbein chisels, paired w cutting edges in opposite directions The semicircular indentation on both sides of the shank allows the instrument to engage around the tooth and into the interdental area
46
What type of incision is this?
External bevel incision or gingivectomy
47
Type of incision?
Internal bevel incision. starts at the surface of gingiva and is directed apically to crestal bone. Incision from which the flap is elevated
48
Name the instrument
Schluger interproximal file
49
Name the instrument
Sugarman interproximal file
50
What are these instruments?
Back action chisels
