module 8 review

Question 1

hierarchy

Answer 1

1) urgent
2) control (caries, perio, extraction, endo)
3) re eval (holding phase)
4) definitive (ortho)
5) maintenance

Question 2

ortho TP stages

Answer 2

1) problem list and diagnosis
2) orthodontic problems in priority order
3) possible solutions
4) patient parent discussion
5) TP

Question 3

ortho records generally do not take

Answer 3

1) MRI, TMJS
- because there is CBCT

Question 4

ortho records

Answer 4

1) lots and lots of photographs
2) look at centerline, overbite/jet, missing teeth
3) evaluate jaw to the cranial base

Question 5

levels of crowding in the patient

Answer 5

1) mild 0-4
2) moderate 4-8
3) severe >8

Question 6

pano you can obtain

Answer 6

1) length of roots
2) NOT occlusion of teeth
- the peg upsets the underlying skeletal pattern
3) presence of pathology in the TMJs
4) restorations in teeth
5) root morphology

Question 7

wits analysis

Answer 7

1) sagittal measurement
2) linear measurement
3) constructed using the occlusal plane point A (maximum concavity of maxilla) and B (on mandibular)
4) relates the upper and lower jaw

Question 8

sella

Answer 8

1) located by visual inspection
2) landmark point and not an angle or linear measurement
3) not a bilateral structure
4) used in many cephalometric analyses
5) geometric center of pituitary fossa

Question 9

nasion

Answer 9

1) where the frontal nasal suture is!!!
2) is a landmark point, point landmark and not a linear measurement
3) in midsagittal point

Question 10

a point

Answer 10

1) the maxilla
2) the most posterior midline point in the concavity between ANS and prosthion
3) used to assess the most reliable anterior aspect of the maxilla

Question 11

phases of ortho

Answer 11

1) leveling and aligning - niti
2) working - round and rectangular stainless steel (moving teeth to correct occlusion)
3) finishing and detailing - strong stainless steel with bends

Question 12

goals should be correct by the time you are considering going into the working phase

Answer 12

1) all rotations correct
2) all teeth aligned and level
3) pano radio to check for root parallelism and root resorption
4) all bracket repositioning carried out

Question 13

prior to finishing phase

Answer 13

1) class I occlusion
2) incisal overjet is corrected
3) incisal overbite is corrected
4) extraction spaces closed

Question 14

finishing phase

Answer 14

1) fine in and out movements
2) fine vertical positions
3) smile mini esthetics
4) best smile arc

Question 15

six keys to occlusion

Answer 15

1) no rotations
2) crown angulation correct
3) crown inclination correct
4) no spaces
5) flat or acceptable curve of spee
6) upper first molar to lower first molar
- MB cusp of upper in MB groove in bottom
- DB cusp of upper molar in marginal ridge of lower second molar
