Q

Retainer (clamps) function

A

provide a stable anchor for the system at the most distal aspect

31
Q

Components of retainers

A 
Prongs (4)
Holes (2 usually)
Bow
Jaw
Wings (not on all)
32
Q

Tooth retainer goes on

A

most distal tooth that is in operating window

33
Q

Function of wings on retainers

A

hold the RD out of the way during placement and operation, but can restrict restorative access

34
Q

Number of prongs engaged with tooth?

A

4 prong-helps pick the retainer

35
Q

Function of the frame of a retainer

A

to hold and stretch the RD material to improve visibility and help create a space for access

36
Q

Engage the retainer where on the tooth?

A

below the height of contour-around the neck of the tooth is best

37
Q

Punch funtion (RD)

A

Place holes in the RD material

38
Q

Considerations when punching

A

conform to patients arch

39
Q

punch holes too close together

A

RD will stretch and result in gaps (leaking)

40
Q

Holes too far apart

A

RD will be bunched up and result in poor sealing (leaking)

41
Q

Autoclave RD Punch?

A

NO- will dull it

42
Q

Forcep function

A

utilize to place the retainer in position on the tooth and to remove the retainer after completion

43
Q

Lubricant function in RD

A

may be placed on the underside of the rubber dam to aid in placement-usually in difficult spors in interproximal

44
Q

Lubricant may be applied …. (2 scenarios)

What should not be used?

A

on underside of dam to aid in placement (for hard interproximals)

to a patients lips to aid in comfort-not vaseline

45
Q

Napkin function-I wish this was a joke

A

absorbs excess saliva, aids in patient comfort, some dams have a built in patient side

46
Q

alternative to vaseline that should be used

A

gel toothpaste

47
Q

a poor rubber dam may be ______ effective and, therefore, a ________ isolation method

A

less effective

less valuable

48
Q

Achieving adequate and effective _____ is of primary importance

A

Isolation

49
Q

Five Steps of Rubber Dam Usage

A

Determine the operating field

Prepare the RD

Select proper retainer

Place the RD

Remove the RD

50
Q

Aramentarium of dental dam (~9)

A 
dam and frame
Rubber dam
Dental floss
Scisors
Dam templates
Forceps 
Retainers
Punch
51
Q

determining operating filed for post teeth

A

place a retainer (at least) one tooth distal to tooth you are working on and cross the midline with the holes
(ex restore tooth 29 and place on 31 to 21)

52
Q

Ant tooth RD placement

A

place from 1st bicuspid to 1st bicuspid

53
Q

Number of retainers used in RD placement for ant

A

One must be used

Two may be used

54
Q

Why might canines be a poor tooth to terminate on?

A

morphology

55
Q

Anchor with retainer or

A

floss

56
Q

Use a powdered dam powder goes which way

A

Down towards patient

57
Q

Attach floss to _____

A

retainer bridge-Always

58
Q

winged retainer place on dam in hole for ______

A

most distal tooth

59
Q

________ to bring dam between contacts

A

floss

60
Q

Place dam frame _____

how is it orientated

A

tips up/convex surface out (mimic convexity of the face)

61
Q

Convexity of frame

A

mimics convexity of face

62
Q

Inverting the dam

A

tuck damn around necks of optimizes isolation

63
Q

Rubber dam removal

what should you not do?

A

Stretch dam, pull buccally or lingually (lateral not occlusal), cut it, pull out, double check for things left in mouth (sulcus)

64
Q

Ligatures (how and where)

Where is the floss placed into?

A

place ligature on tooth to be restored and on tooth each side-floss is placed into sulcus; on working tooth and those around it

65
Q

Dam on the wing, good or not?

A

BAD

66
Q

Rubber dam material _____ the neck of the tooth

A

hugs/is tight to

67
Q

What is critical in moisture control of a rubber dam

A

isolation

-from gingival fluid, saliva, bleeding

68
Q

With clean preparation walls, improved likelihood of

A

restoration success

69
Q

The HVE is excellent for what

A

debris removal in pros

70
Q

Most effective isolation method

A

Rubber dams

71
Q

Do rubber dams enhance restorative material outcome?

A

Yes!

72
Q

Possible con of wings on retainers?

A

Can restrict restorative dentistry

73
Q

When placing a retainer on a tooth, Engage ____ or ____ Tines Then Set Opposite Side of Retainer
