What is the purpose of the mandibular function and provocation tests?
|
-Test for soreness in the lateral and medial pterygoid muscles, which are not easily accesssible to palpation
|
|
|
Pain the inferior lateral pterygoid muscle will manifest in the ___ ___, while pain in the medial pterygoid will be felt in the area of ____.
|
-Inferior lateral pterygoid muslce = pre-auricular region
-medial pterygoid = area of masseter |
|
|
Describe the Clinical Mandibular Function Test?
|
-Open wide: Test for pain in medial pterygoid (stretch) and TMJ
-Clench: Test for pain in medial pterygoid (contraction), inferior lateral pterygoid (stretching), -L&R lateral movement |
|
|
What does Resisted Movement test?
|
-Test inferior lateral pterygoid
-Resisted Protrusion tests ILP on boths sides -Resisted Right lateral movements test LEFT ILP -Resisted Left lateral movements test RIGHT ILP |
|
|
Clench on Separator
|
a. Clench on right separator-loads the left TMJ
b. Clench on left separator-load the right TMJ c. Clench on bilateral separator i. UNLOADS both TMJs-NO PAIN ii. No lateral pterygoid pain iii. Contracts medial pterygoid-possible pain |
|
|
Describe how would you palpate muscle?
|
-Flat part of 2nd and 3rd finger tips
-palpate only one muscle at a time -use 2lbs of presure to palpate extra-oral muscles -use only 1lbs of pressure intraoral muscles |
|
|
pain in TMJ can mean?
|
-Capsulitis or Synovitis
|
|
|
Distinguish b/t masseter and TMJ
|
-Masseter msucle bulges when clenching
-TMJ felt when patients open and closes jaw |
|
|
How can the vertical reference be identified?
|
-If maxillary and mandibular incisors mildines are coincident, use midline
-If max and man incisors midline sare not coincident, use facial of #8 for lower midline -If max and man incisors ar emissing, facial midlines such as the labial frena can be used |
|
|
When is maximum assisted opening performed?
|
-Performed if maximum opening < 35 mm
-Apply gentle and steady force |
|
|
What is the difference b/t SOFT end fell and HARD end feel? (term describe restriction that limits the full range of motion)
|
-Soft end feel: Max. opening increase with assistant (Muscle-induced restriction)
-Hard end feel: Max. opening doesn't change with asisstant (TMJ-induced restriction) |
|
|
How to distinguish opening deviation b/t Joint and Muscle?
|
-Joint: Ass. with joint sound
-Muscle: Not ass. with joint sound |
|
|
How to distinguish opening deflection b/t Joint and Muscle?
|
-Joint: Ipsilateral opening deflection (w/ ipsilateral deviation on protrusion)
-Muscle: Ipsilateral opening deflection (muscle lateral to joint) -No deflection on protrusion |
|
|
Intraoral examination should pay specific attention to 4 key factors?
|
-Tooth wear
-Tooth mobility -Cheek indentation -Tongue indentations |
|
|
Examination of Current Splint?
|
-Examine the type of material (max/man, partial/full-coverage, soft/acrylic)
-Fit -Retention -Stability -Occlusion: centric stops, lateral guidance protrusive guidance |
