TMJ analysis, occlusal recording, open bite CR record

Question 1

when should you take models and mount them?

Answer 1

1) take them in the first visit if you expect there to be ANY indirect work

Question 2

if you go past adaptive capability

Answer 2

1) you will see symptoms

Question 3

three tabs

Answer 3

1) TMD screening
- for every exam and recall
2) baseline occlusal exam and TMJ
eval
- for initial patient visit!!!
- palpate muscles (one touch)
3) centric relation and or complex case
- for splint or complex case

Question 4

MI observation

Answer 4

1) bite all the way down
2) classify their canines
3) functional horizontal overlap
- flaring
- it is not the same as overjet
4) the least limiting tooth is the most note worthy
- the “closest tooth” for FHO of incisors

Question 5

wear facets

Answer 5

1) mark from minimal, moderate, to severe
2) group function increases over time as teeth wear down

Question 6

excursive guidance from MI (also part of periodontal exam)

Answer 6

?

Question 7

ineffective anterior guidance

Answer 7

do not separate posterior teeth

Question 8

complex/splints

Answer 8

1) discomfort to load testing
2) CR-MI discrepancy
3) can refer out

Question 9

centric relation

Answer 9

1) condyles in optimal CR
2) condyle braced up against healthy disc anterior superiorly against the slope
3) do shorter and shorter strokes until tooth hit
- deprogramming
4) you can use the leaf gauge and figure our which tooth hits

Question 10

shim stock contacts

Answer 10

1) which teeth hold shimstock
- real coupling of teeth

Question 11

lateral component

Answer 11

1)

Question 12

leaf gauge as discluder

Answer 12

1)

Question 13

cr record

Answer 13

1) needs to be a tripod
- bicuspid to central molar, dab in central incisors
2) need to put lead guage in there 12-13 leafs more than when you first make contact
3) should capture both buccal and lingual cusp tips of both maxillary and mandibular teeth for stability
