interdisciplinary tx

Question 1

venn diagram of tx

Answer 1

Question 2

FACTORS TO CONSIDER IN THE PRESERVATION OF A TOOTH

Answer 2

Question 3

treatment sequence for interdis care

Answer 3

it of the upmost importance

Question 4

1st step to interdisciplinary care

Answer 4

1st. Establish posterior occlusal support, without this there will be a deepbite

Question 5

Ferrule Effect

Answer 5

• A BAND OF DENTIN (1MM) BETWEEN THE POST AND THE INTERNAL LINE OF THE CROWN
• IMPROVES PROGNOSIS DRAMATICALLY AND REDUCES THE RISK OF ROOT FRACTURES

Question 6

Selection Criteria for extrusion
Crown root?
anatomy of?
Amount of?
Relevance?
Esthetic?

Answer 6

Crown root ratio
Root anatomy
Amount of extrusion needed
Relevance to keep the root
Esthetic concerns.

Question 7

PREPARATION FOR EXTRUSION

Answer 7

• YOU MAY NEED A TEMPORARY POST UNTIL ROOT IS EXTRUDED
• TEMPORARY CROWN CEMENTED PERMANENTLY to withstand extrusive forces

Question 8

gingival line with extrusion

Answer 8

SLOW Orthodontic extrusion may result in an uneven gingival line
* Fiberotomies can decrease the extent of the lowering if the gingival crest

Question 9

One of the advantages of orthodontic extrusion regarding bone?

Answer 9

One of the advantages of orthodontic extrusion is that it significantly reduces the amount of bone recountouring of adjacent teeth during the CCL procedure

Question 10

healing phase length with temp crowns

Answer 10

6 wks

Question 11

Bracketing for extrusion

Answer 11

bracket of extrudued tooth superior to allow wire to place extrusive force on tooth

Question 12

Passive Technique

Answer 12

Brackets are positioned to minimize movement of anchor teeth

Question 13

alveolar bone with SLOW extrusion

Answer 13

follows the extrusion

Question 14

Rapid Extrusion: force?
* wire?
* Goal is to?
* Activate wire how much/when?

Answer 14

Heavy force=Rapid movement
* 0.017x0.025 Beta titanium rectangular wire with bends to place large extrusive forces
* Goal is to extrude the tooth while maintaining the alveolar level.
* Activate wire 1mm every 3 weeks

Question 15

Answer 15

rapid extrusion with anchor teeth and heavy rectangular wire

Question 16

Fiberotomies with extrusion
how often?
* Minimize?
* mechanism

Answer 16

Every 2-3 weeks
* Minimize the descent of the alveolar bone
* Severing the supracrestal fibers reducing the effect on the alveolar bone

Question 17

Stabilization with extrusion
* time?
* Keep the appliance in?
* Let the gingival tissue?

Answer 17

• 8 weeks post-final orthodontic tooth movement
• Keep the appliance in a passive state
• Let the gingival tissue reorganize and remodel

Question 18

how can we use ortho for implants

Answer 18

space creation

Question 19

when could intrusion be useful?

Answer 19

we could intrude supererupted teeth to allow for space to restore edentulous areas

Question 20

how can we use ortho for crowns?

Answer 20

extrusion to prevent BW violation

Question 21

explain this setup

Answer 21

B/L intrusive forces placed on molar with heavy rectangular wire.
band from palatal screw also contributes an intrusive force.
likely to create space for restoration of antagonist
