  • 7. 
    Articulators may be employed in orthodontic treatment planning, especially extraction cases. The most common use of articulators is for diagnosis.
    • A. 

      Both statements are true.

    • B. 

      Both statements are false.

    • C. 

      The first statement is true; the second is false.

    • D. 

      The first statement is false; the second is true.

  • 8. 
    Elastic ligatures used in ortho tx may be placed on hooks placed on diagonally-opposing teeth to generate forces.
    • A. 

      True

    • B. 

      False

  • 9. 
    The articular eminence of the articulator should be on the upper member. The semi-adjustable WhipMix articulator is an ARCON type, meaning it has ARticulating CONdyles.
    • A. 

      Both statements are true.

    • B. 

      Both statements are false.

    • C. 

      The first statement is true; the second is false.

    • D. 

      The first statement is false; the second is true.

  • 10. 
    Identify the applications of articulators in digital dentistry:
    • A. 

      Combining technologies such as CBCT and digital impressions

    • B. 

      Capturing eccentric records

    • C. 

      Restoration design software

    • D. 

      Positioning models accurately (digital facebow)

    • E. 

      Replicating mechanical articulator shape and contours

    • F. 

      Capturing MIP

  • 11. 
    Non-adjustable articulators are the most prevalent type used by U.S. dentistry. Non-adjustable articulators may accurately reflect patient opening and closing pathways, but not accurately reflect patient lateral and protrusive excursions.
    • A. 

      Both statements are true.

    • B. 

      Both statements are false.

    • C. 

      The first statement is true; the second is false.

    • D. 

      The first statement is false; the second is true.

  • 12. 
    Because mounting with non-adjustable articulators is arbitrary, the use of interocclusal records enhances prosthesis outcomes for the patient.
    • A. 

      True

    • B. 

      False

  • 13. 
    With a semi-adjustable articulator, it is possible to nearly match the patient in replicating occlusal contacts and eccentric motions. The most advantageous feature of semi-adjustable articulators is that they are roughly the size of the patient's anatomy.
    • A. 

      Both statements are true.

    • B. 

      Both statements are false.

    • C. 

      The first statement is true; the second is false.

    • D. 

      The first statement is false; the second is true.

  • 14. 
    Select the 3 common adjustments for semi-adjustable articulators:
    • A. 

      Condylar inclination

    • B. 

      Lateral translation (Bennett angle)

    • C. 

      Intercondylar distance

    • D. 

      Maxillary width

    • E. 

      Interdental spacing

  • 15. 
    Setting the condylar guidance to "FB" is necessary when mounting with the indirect system on a semi-adjustable articulator.
    • A. 

      True

    • B. 

      False

  • 16. 
    In using the direct mounting technique with the WhipMix 2240 articulator, the brass peg on the upper member represents the auditory canal.
    • A. 

      True

    • B. 

      False

  • 17. 
    Protrusive interocclusal records are used to set condylar guidance bilaterally while lateral interocclusal records are used to set condylar guidance unilaterally.
    • A. 

      True

    • B. 

      False

  • 18. 
    Lateral interocclusal records accurately capture immediate side shift within a 3-5mm laterotrusive excursion.
    • A. 

      True

    • B. 

      False

  • 19. 
    Measurements of laterotrusive condylar inclination are often greater (and therefore should be corrected) than those of protrusive condylar inclination.
    • A. 

      True

    • B. 

      False
