Q

Why might behavioral issues be an indication for an SSC instead of a restoration?

31
Q

Which crowns have curved axial design

A

Pre-countoured ION/ESPE

32
Q

Which crowns have anatomically defined occlusal surfaces

A

ION/ESPE

33
Q

Which crowns require less manipulation to accurately fit a prepared tooth

A

ION/ESPE

34
Q

What are the 5 steps for fitting a SSC

A
  1. Pick size
  2. Length of crown
  3. Marginal adaptation
  4. Contouring
  5. Crimping
35
Q

What measurement is used to help in crown selection

A

mesio-distal width

36
Q

How should the crown be placed?

A

Set lingually and rotate over the buccal slope

37
Q

Should you have to use a lot of force to put the crown on?

A

no, it should go into place with little pressure

38
Q

What is the problem if the crown easily slides over the tooth with no pressure

A

It is too big

39
Q

What is the problem is the crown will not seat entirely over the tooth

A

it is too small

40
Q

If a crown is too large or a crown before contouring might cause this

A

Blanching of the tissue

41
Q

What should you do if a snug fit cannot be obtained

A

reduce buccal and lingual surfaces slightly

42
Q

How do you adjust the crown fit if needed

A

With the crown in place scribe line along buccal and lingual gingival crest

43
Q

When trimming the crown how much excess should be trimmed off?

A

Enough so that the margins are 1.0 mm below the scribed line

44
Q

What instruments decrease the circumference of the crown while creating a fit that is more snug

A

Contouring pliers

45
Q

What should you inspect after fitting in terms of the crown margin

A
  1. Inspect the crown for exposed tooth structure and open margins
  2. Crown margin should be 1 mm below gingial crest
46
Q

What does contouring do to the crown circumference

A

Reduces

47
Q

How do you contour the crown

A

Use contouring pliers to bend inward the gingival third of the crown…..more contouring on buccal and lingual

48
Q

Why are crown margins crimped

A

Ensure good cervical marginal adaptation

“Snap” seating

49
Q

What are the two common crown cements used

A

Polycarboxlyate

Glass Ionomer

50
Q

What can you use to have the child help seating the crown

A

Band seater or bite stick

51
Q

Three steps to complete crown cementation

A
  1. check that crown is comletely seated
  2. Remove excess cement when tacky
  3. Use floss to clean interproximal areas
52
Q

What are the four bullet items for the final check of the crown restoration

A
  1. check for interproximal and subgingival cement
  2. Polish crown surface lightly with pumice
  3. Check occlusion
  4. Ignore minor occlusal discrepanciees
53
Q

Which tooth adjusts itself very quickly

A

primary molars

54
Q

What is usually the cause of a crown not seating properly?

A

A proximal ledge which should be removed with a tapered bur

55
Q

What is usually the solution to a loss of space?

A

Rotate the crown slightly mesio-buccally

Use flat beaked pliers to flatten the contact points, this reduces the mesio-distal width

56
Q

what are the pliers with the little hook like things on the end

A

Howe pliers

57

A

No

58
Q

Crowns are significantly better than restorations if the child is under _____ years of age

A

5

59
Q

Crown and alloy are not significantly different if tooth is due to be exfoliated within _____ years

A

3

60
Q

What is the main goal behind using SSCs

A

To keep primary teeth restored until they are ready to exfoliate

61
Q

What do you want to avoid when deciding to use a crown?

A

Re-treatment

62
Q

Things to consider

A

Patient behavior v. restorative techniques

Longevity/durability of the restoration material

Ability to maintain the restored tooth by appropriate diet and OH

63
Q

What are the 5 indications for strip crown

A
  1. Extensive or multi surface caries
  2. Congenitally malformed teeth
  3. Discolored teeth
  4. Fractured teeth
  5. Sufficient crown material remains after caries removal to retain resin
64
Q

What are the materials needed for a strip crown restoration

A
  1. Anterior restorative materials
  2. Celluloid crown forms in various sizes
  3. Scissors to trim crown form
65
Q

During a strip crown prep, how are the caries removed?

A

With a round bur on slow speed to protect the pulp

66
Q

What are tapered burs used for during a strip crown prep?

A

Interproximal and incisor reduction

67
Q

What are the 3 steps to forming the celluloid crown for the strip crown prep

A
  1. Crown form trimmed so cervical margin extends slightly below gingival crest
  2. Height adjusted to match adjacent tooth
  3. Vent hole placed
68
Q

What are the 3 steps to prepare the tooth surface for a strip crown

A
  1. Pulp protection applied
  2. Tooth surface etched, washed and dried
  3. Bonding agent applied and cured
69
Q

What do you want to avoid when squeezing material into the crown form

A

creating voids

70
Q

When the crown is seated, where should the excess composite come out?

A

Cervical opening and vent holes

71
Q

Usually you need to cure to a depth of _____ mm

A

4

72
Q

Why are they called strip crowns?

A

Because you strip off the crown form after the composite is cured

73
Q

What are 4 other types of anterior crowns

A

SSC
EZ Pedos
SSC w/ Facial cutout and composite (Window)
