FACTORS TO CONSIDER IN THE PRESERVATION OF A TOOTH
treatment sequence for interdis care
it of the upmost importance
1st step to interdisciplinary care
1st. Establish posterior occlusal support, without this there will be a deepbite
Ferrule Effect
- 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
Selection Criteria for extrusion
Crown root?
anatomy of?
Amount of?
Relevance?
Esthetic?
Crown root ratio
Root anatomy
Amount of extrusion needed
Relevance to keep the root
Esthetic concerns.
PREPARATION FOR EXTRUSION
- YOU MAY NEED A TEMPORARY POST UNTIL ROOT IS EXTRUDED
- TEMPORARY CROWN CEMENTED PERMANENTLY to withstand extrusive forces
gingival line with extrusion
SLOW Orthodontic extrusion may result in an uneven gingival line
* Fiberotomies can decrease the extent of the lowering if the gingival crest
One of the advantages of orthodontic extrusion regarding bone?
One of the advantages of orthodontic extrusion is that it significantly reduces the amount of bone recountouring of adjacent teeth during the CCL procedure

6 wks
Bracketing for extrusion
bracket of extrudued tooth superior to allow wire to place extrusive force on tooth
Passive Technique
Brackets are positioned to minimize movement of anchor teeth
alveolar bone with SLOW extrusion
follows the extrusion
Rapid Extrusion: force?
* wire?
* Goal is to?
* Activate wire how much/when?
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
rapid extrusion with anchor teeth and heavy rectangular wire
Fiberotomies with extrusion
how often?
* Minimize?
* mechanism
Every 2-3 weeks
* Minimize the descent of the alveolar bone
* Severing the supracrestal fibers reducing the effect on the alveolar bone
Stabilization with extrusion
* time?
* Keep the appliance in?
* Let the gingival tissue?
- 8 weeks post-final orthodontic tooth movement
- Keep the appliance in a passive state
- Let the gingival tissue reorganize and remodel
how can we use ortho for implants
space creation
when could intrusion be useful?
we could intrude supererupted teeth to allow for space to restore edentulous areas
how can we use ortho for crowns?
extrusion to prevent BW violation
explain this setup
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
