A

crown

22
Q

What are types of materials used for fixed restorations?

A

23
Q

What are the pros of gold crowns (similar for non-gold metal crowns):

A
  1. gentle on gingiva
  2. low wear on opposing teeth
  3. longest lasting restoration we have in dentistry so far
  4. can be burnished to seal smallest of margins
  5. contacts can be added
  6. easily polished
24
Q

What are the cons for gold crowns (similar for non-gold metal crowns):

A
  1. not esthetic
  2. labor intensive for lab tech
25
Q

What are the pros for ceramic crowns:

A
  1. tooth colored
  2. still stronger than enamel by 2x
  3. most realistic and beautiful of all crown materials
26
Q

What are the cons for ceramic crowns:

A
  1. must use resin cements 90% of the time
  2. careful patient selection needed for molar crowns
  3. require thicker margins as ceramics need a minimum amount of material to prevent fracture
  4. fracture risk
27
Q

What are the pros for zirconia crowns:

A
  1. tooth colored
  2. some iterations are 4x as strong as enamel
  3. becoming more esthetic
  4. easy for lab tech to fabricate
28
Q

What are the cons for zirconia crowns:

A
  1. not all zirconias are the same
  2. cannot easily add materials to establish contacts
  3. crown preparation design still key for longevity
  4. fracture risk with some formulations
29
Q

What are the pros for porcelain fused to zirconia crowns:

A
  1. tooth colored
  2. some iterations are 4x as strong as enamel
  3. becoming more esthetic
  4. no dark metal (like PFM) to cover
  5. White substructure enhances esthetics with porcelain providing high esthetics
30
Q

What are the cons for porcelain fused to zirconia crowns:

A
  1. not all zirconias are the same
  2. cannot easily add material to establish contacts
  3. crown preparation design still key for longevity
31
Q

What are the pros of CEREC Composite formulation crowns:

  2. easy for lab tech to fabricate
  3. milled restorations
  4. mixture of composite and ceramic
32
Q

What are the cons of CEREC Composite formulation crowns:

A
  1. longevity still in research
  2. cannot easily add material to establish contacts
  3. crown preparation design still key for longevity
  4. esthetics still challenging
33
Q

What are the pros of PFM crowns:

A
  1. tooth colored
  2. metal substructure adds strength
  3. metal substructure enables PFMs to be used in longer bridges
  4. can design where porcelain covers metal to provide excellent flexibility in design
  5. metal substructure protects tooth even if porcelain fractures
34
Q

What are the cons of PFM crowns:

A
  1. porcelain can fracture if not prepared correctly
  2. metal collars can be unesthetic
  3. porcelain can stain yellow over time

37
Q

How long do single crowns last?

A

average single crown lasts 10-15 years
(some material have a longer life span than this)

38
Q

List the longevities on average of crowns, conservative amalgams, and conservative composites:

A

Crown: 10-15 years
Conservative amalgam: 10-15 years

39
Q

Treatment planning a crown begins with:

A

Patient history

40
Q

Prior to working on a patient what should be taken?

A

A global analysis of patients overall all oral health

41
Q

Following a global analysis of patients overall oral health, you should:

A

Analyze the tooth to be treated

42
Q

What are two questions you should ask yourself in regards to analysis of the tooth to be treated?

A
  1. how much of the tooth is compromised
  2. what is needed to restore the tooth
43
Q

When identifying options to restore the tooth, the

  1. best option=
  2. better=
  3. acceptable=
  4. not an option=
A
  1. esthetics & strength
  2. strength
  3. repair the tooth but not necessarily strengthen it
  4. not a reasonable option for the patient
44
Q

Patient presents to your office with no pain or sensitivity. You notice decay on the buccal of #30 which compromises the integrity of the existing amalgam.

What information do you need to gather in order to treatment plan #30 for a new restoration?

What are the options available here for this patient?

Can you list the best, better, acceptable, and not an option for this patient?

A

X

45
Q

Patient presents to your office with no pain or sensitivity. You notice decay on the occlusal of #30 which compromises the integrity of the existing amalgam.

What information do you need to gather in order to treatment plan #30 for a new restoration?

What are the options available here for this patient?

Can you list the best, better, acceptable, and not an option for this patient?

A

46
Q

What type of damage is seen in this image? How would you treat this patient?

47
Q

-Patient presents to your office with a broken tooth
-No significant medical/dental history
-Bitewing radiograph taken
-Patient reports no pain, but tooth is sharp to his tongue
-Patient home care is in stable condition

What additional information do you need?

A
  1. PA radiograph to see apex
  2. Perio charting
48
Q

-Patient presents to your office with a broken tooth
-No significant medical/dental history
-Bitewing radiograph taken
-Patient reports no pain, but tooth is sharp to his tongue
-Patient home care is in stable condition
-What does this image reveal?

A

Loss of cusp and greater than 50% of tooth structure compromised

49
Q

-Patient presents to your office with a broken tooth
-No significant medical/dental history
-Bitewing radiograph taken
-Patient reports no pain, but tooth is sharp to his tongue
-Patient home care is in stable condition
