Interdisciplinary Tx Flashcards
What is more important to establish for teeth first? Posterior support or anterior esthetics?
Posterior support first
- Improves prognosis dramatically and
reduces root fracture risks. - A band of dentin (1mm) between
the post and the internal line of the
crown .
Ferrule
What do you want to have for crown to root ratio for ortho to extrude? Ratio and mm
1/2 : 10mm
How many mm do you typically extrude?
2-3 mm
What are the 2 things needed in preparation for extrusion?
*You may need a temporary
post until root is extruded.
*Temporary crown
cemented permanently
What is the reasoning ortho extrusion is done rather than CCL in some cases?
CCL requires more bone removal across multiple teeth
Does a slow or fast extrusion bring bone and gingival down with the movement?
Slow
One of the advantages of orthodontic extrusion is that it significantly
reduces the amount of bone recountouring of adjacent teeth during the
____ procedure
CCL
What type of wire is used as preferred method to extrude teeth?
High force wire: can use smaller wire and do CCL later
How many teeth are bracketed in extrusion cases?
2-3 on each side of tooth extruding
If you use high force wires, how often are fiberotomies done?
Every 3 weeks
Does a more conical or cyclindrical tooth more at risk for black triangles in extrusion cases?
Conical
___ bracketing is done on the anchoring teeth for extrusion?
Passive bracketin
Beta titanium wire (TMA) is about ___% as strong as stainless steel as it is used for rapid extrusion
50%
*Minimize the descent of the
alveolar bone.
*Severing of supracrestal fibers
reducing the effect on the
alveolar bone
Fiberotomies
