Introduction

Question 1

A ________ allows for minimal teeth movement.

Answer 1

stable dental arch

Question 2

What is a consequence of a dental arch with compromised stability?

Answer 2

Useless opposing teeth and tooth movements

Question 3

_______ is movement of the tooth beyond the occlusal plane due to absence of an opposing tooth.

Answer 3

Supraeruption

Question 4

What are some consequences of supraeruption?

Answer 4

Compromised embrasures
Plaque accumulation interproximally
Sensitiviy due to exposure of root surface
Compromised arch stability

Question 5

Extraction of molars without subsequent replacement would compromise arch stability and cause _______ of the premolars.

Answer 5

distalization

Question 6

What are the four main issues that result from prolonged absence of teeth?

Answer 6

1. Malocclusion
2. Decreased chewing efficiency
3. Esthetics
4. Alterations in speech

Question 7

What are the four options for restoring an edentulous area?

Answer 7

1. Implant supported FPD (implant)
2. FPD (bridge)
3. Removable Partial Denture (RPD)
4. Orthodontic treatment

Question 8

What are three advantages to using implants?

Answer 8

• Do not remove tooth structure of adjacent teeth
• Crowns may be retrievable
• Single implant= FPD in cost

Question 9

What are the disadvantages to using implants?

Answer 9

• Requires surgery
• Healing time ~3-6 months
• May need temporary prosthetic (flipper) $
• Requires extra planning time
• Patient must meet selection/health criteria
• Mechanical problems (keeping screws tight)

Question 10

True or False: Implant screws are resistant to fracture.

Answer 10

False

Question 11

If there is an anatomical limitation to implants, such as insufficient bone due to collapse after extraction, what must be done before implanting?

Answer 11

-Ridge Augmentation
-Bone graft
-Guided tissue regeneration
PLAN PLAN PLAN (time/cost/complications)

Question 12

What are the five components of a Fixed Partial Denture?

Answer 12

1. Retainer
2. Abutment
3. Edentulous Ridge
4. Connector
5. Pontic

Question 13

What are the advantages to using a FPD?

Answer 13

• Cemented (feels fairly permanent)

- Capable of good esthetics

Question 14

What are the disadvantages to using a FPD?

Answer 14

• Involve irreversible preparation of minimally restored or unprepared teeth
• Prepared teeth may be susceptible to recurrent decay
• Cost for remake
• Hygiene is important (cemented)

Question 15

When are Removable Partial Dentures indicated?

Answer 15

• When extracted molars needed to be replaced
• When acrylic will improve the esthetics (bone loss)
• When bone loss causes loss of lip support

Question 16

What are the advantages to using RPD?

Answer 16

• Least expensive

- Allow for reproduction of gingiva

Question 17

What are the disadvantages of RPD?

Answer 17

• Require an essential amount of metal framework and tooth support to replace a single tooth
• Takes 6-8 weeks to get used to the way it feels

Question 18

What would be done if there was a limited amount of interproximal space at treatment site?

Answer 18

Orthodontic treatment or ortho+prosth treatment

Question 19

One consideration in tooth replacement involves the preservation of _____ and ______ tissue health.

Answer 19

Soft

Hard

Question 20

What is a Fixed Partial Denture?

Answer 20

Any dental prosthesis that is luted, screwed, mechanically attached, or securely retained to natural teeth, tooth roots, and/or dental implant abutments that furnish the primary support for the dental prosthesis

Question 21

What is an important characteristic of the pontic?

Answer 21

It should place NO PRESSURE on the gingiva

Question 22

Prior to placing an FPD, what should be evaluated for periodontal health and stability?

Answer 22

The abutments
