Flashcards in Introduction Deck (22):
1

A ________ allows for minimal teeth movement.

stable dental arch

2

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

Useless opposing teeth and tooth movements

3

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

Supraeruption

4

What are some consequences of supraeruption?

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

5

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

distalization

6

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

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

7

What are the four options for restoring an edentulous area?

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

8

What are three advantages to using implants?

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

9

What are the disadvantages to using implants?

- 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)

10

True or False: Implant screws are resistant to fracture.

False

11

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

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

12

What are the five components of a Fixed Partial Denture?

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

13

What are the advantages to using a FPD?

- Cemented (feels fairly permanent)
- Capable of good esthetics

14

What are the disadvantages to using a FPD?

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

15

When are Removable Partial Dentures indicated?

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

16

What are the advantages to using RPD?

-Least expensive
-Allow for reproduction of gingiva

17

What are the disadvantages of RPD?

- 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

18

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

Orthodontic treatment or ortho+prosth treatment

19

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

Soft
Hard

20

What is a Fixed Partial Denture?

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

21

What is an important characteristic of the pontic?

It should place NO PRESSURE on the gingiva

22

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

The abutments
