Exam 2 (Review slides 31-41)

Question 1

3 procedures are necessary to use the fully adjustable articulator properly and effectively:

Answer 1

1. An exact hinge axis location of the condyles for the facebow
2. A pantographic recording
3. A CR occlusal record

Question 2

Working side occlusal interferences

Answer 2

1. Lingual inclines of the maxillary posterior facial cusps
2. Facial inclines of the mandibular posterior facial cusps
3. Lingual inclines of the maxillary posterior lingual cusps
4. Facial inclines of the mandibular posterior lingual cusps
   (1,2 –> A contact 3,4 –> C contact)

Question 3

Location of non-working interferences of the mandible

Answer 3

Lingual inclines of the mandibular posterior facial cusps

Question 4

A & C contacts will display the condyle on what side deviating laterally? The condyle on what side of the interference is anterior to the CR position?

Answer 4

Opposite

Same side

Question 5

Myofascial pain Syndrome definition

Answer 5

Pain of a regional nature beginning within a specific trigger point within muscle/fascia

• Pain can refer to other areas of the body
• Associated phenomena may include autonomic abnormalities such as blanching, coldness, sweating, erythema, hyperesthesia, and hyperalgesia. These may be locally or within the area of referred pain.

Question 6

Define Muscle Trismus:

Answer 6

1. Pain is variable
2. Incisal-interocclusal distance is less than 18 mm
3. Hard end-feel
4. Is a reversible process
5. Condition is secondary to: Infection, Hematoma & Trauma

Question 7

Anterior temporalis is a trigger to what?

Answer 7

Maxillary incisors

Question 8

Disc displacement with reciprocal click define opening click and closing click

Answer 8

Opening click: Regaining position

Closing click: Articular disc pops out of position to the anterior, very near closed

Question 9

Intracapsular disorders can elicit pain with increased or decreased interarticular pressure and mandibular movement?

Answer 9

Increased interarticular pressure

Question 10

Intracapsular disorders; Any movement provoked by manipulation of the mandible will elicit what?

Answer 10

Elicit pain if it increases pressure on the TMJ

Question 11

Intracapsular disorders: If the patient has pain from biting on the tongue blade, what will continue to exhibit pain?

Answer 11

The inferior lateral pterygoid muscle

Question 12

Intracapsular disorders: Having a patient protrude their mandible aginst resistance as they bit will not do what?

Answer 12

Increase pain if the problem is intracapsular but will increase pain if it is the inferior lateral pterygoid muscle

Question 13

Intracapsular disorders: Biting on opposite side of affected joint will do what?

Answer 13

Increase pain

Question 14

Pain input: A patient suffering from necrotic pulp pain will limited mouth opening once the pain is resolved will not return to normal ROM. (T or F)

Answer 14

False, will return to normal ROM.

• Be careful not to confuse with this situation with TMD

Question 15

Pain input: A patient with pain in the cervical spine can produce a reflex muscle response in the trigeminal area, most notably the muscles of mastication

Answer 15

True

• Be careful not to confuse this situation with TMD

Question 16

Spontaneous dislocation/Subluxation Eminence: Repositioning of the condyle to its normal position may need what?

Answer 16

Manipulation of the mandible by a clinician
