-Comment in 2006, Gross _______ can predispose to TMD
disharmonies… disharmonies
Myth: Pretreatment radiographs of both TMJs should be taken to determine the _____ of the condyles in the fosse, and the orthodontic treatment should be directed toward getting the condyles in concentric relation to their _____
position…fossa
Myth: Orthodontic treatment when properly done, usually______ the likelihood of subsequently developing TMD
reduces..
Finishing orthodontic cases according to specific functional occlusal guidelines, will _____ the likelihood of developing TMD
reduce
Myth: The use of certain _______ procedures (bicuspid extraction, incisor retraction, etc.) or appliances (headgear, chin cups, Class II elastics, etc.) may increase the likelihood of developing TMD
-Comment in 2006. These devices can ______a pre-existing TMJ condition.
traditional….aggravate
Myth: Adult patients who have _______ TMD symptoms and some form of occlusal “problem” require some type of occlusal correction in order to get well and stay well
concurrent…
Myth: The retrusion of the mandible because of ______causes (deep overbite, distalizing occlusal contacts) or iatrogenic procedures (chin cups, incisor retraction, retention during growth spurts) is a ____factor in the development of TMD
natural…major
Myth: ______of the mandible causes articular disks to skip forward off the condyles, resulting in internal derangements, especially clicking.
-Comment in 2006. Research shows that posterior condyle position _____ for anterior disc displacement with reduction but NOT for pain or arthritic changes.
Distalization …predisposes
a. If you have a unilateral pivot, then it will pull the condyle down (condyle with the pivot) and give relief to the capsulitis inside
b. Dr. Sears bilateral doesn’t know anatomy
c. Unilateral pivot point diagram
Pivot splint
If you want to move jaw forward use:
a. Anterior repositioning appliance
b. Indications for moving jaw forward:
i. posterior capsulitis
ii. painful pop or lots of locking
if you have a patient that has tooth pain and you weren’t sure if that tooth pain is infection or nerve, what test will determine abscess or nerve pain?
a. Topical anesthesia
i. if pain goes away then it is a peripheral neuralgia
ii. LA block will get abscess or nerve so don’t do that
Which muscle will limit side to side movement
lateral pterygoid
If there is nerve pain it is likely to be:
electric
If you have an Infection it is likely to be:
dull achy pain
