Question 1

acquired eccentric relation

Answer 1

any eccentric relationship position of the mandible relative to the maxilla, whether conditioned or learned by habit, which will bring the teeth into contact

Question 2

acrylic resin base

Answer 2

denture base made of acrylic resin

Question 3

adjustable anterior guidance

Answer 3

an anterior guide on an articulator whose surface may be altered to provide desired guidance of the articulator’s movement mechanism; the guide may be programmed (calibrated) to accept eccentric interocclusal records

Question 4

adjustable articulator

Answer 4

an articulator that allows some limited adjustment in the sagittal and horizontal planes to replicate recorded mandibular movements

Question 5

ala-tragus line

Answer 5

line running from inferior border of the Ala of the nose to some defined point on the triages of the ear, usually considered the tip of the triages.
-ideally the Ala-tragus plane is considered to be parallel to the occlusal plane. (which is at an angle of ~ 10 degrees relative to Frankfort horizontal plane)

Question 6

anterior guidance

Answer 6

1. the influence of the contacting surfaces of anterior teeth on tooth limiting mandibular movements
2. the influence of the contacting surfaces of the guide pin and anterior guide table on articulator movements
3. the fabrication of a relationship of the anterior teeth preventing posterior tooth contact

Question 7

anterior guide table and pin

Answer 7

know what these are - the pieces we use on our articulator

Question 8

anterior reference point

Answer 8

any point located on the mid face that, together with two posterior reference points, establishes a reference plane

Question 9

ar-con

Answer 9

contraction of the words “ARTICULATOR” and “CONDYLE” used to describe an articulator containing the condylar path elements within its upper member and the condylar elements within the lower member

Question 10

arrow point tracer

Answer 10

1. a mechanical device used to trace a pattern of mandibular movement in a selected plane - usually parallel to the occlusal plane
2. a mechanical device with a marking point attached to one jaw and a graph plate or tracing plane attached to the other jaw. it is used to record the direction and range of movements of the mandible

Question 11

read and know: articulator and centric relation

Answer 11

NO FLASH CARDS

Question 12

average axis facebow

Answer 12

a device used to relate the maxillary cast to the condylar elements of an articulator using average anatomic landmarks to estimate the position of the transverse horizontal axis on the face

Question 13

average value articulator

Answer 13

an articulator that is fabricated to permit motion based on mean mandibular movements (aka Class III Articulator)

Question 14

base material

Answer 14

any substance of which a denture base may be made (acrylic resin, vulcanite, polestyrene, or metal)

Question 15

centric

Answer 15

1. located in or at a center; central.

2. concentrated about or directed toward a center

Question 16

centric occlusion

Answer 16

the occlusion of opposing teeth when the mandible is in centric relation. may or may not coincide with the maximal intercostal position

Question 17

centric relation record

Answer 17

a registration of the relationship of the maxilla to the mandible when the mandible is in centric relation. the registration may be obtained either intramurally or extra orally.

Question 18

clutch

Answer 18

a device placed in both the maxillary and mandibular arches for the purpose of supporting components used to record mandibular movement

Question 19

condylar guidance

Answer 19

mandibular guidance generated by the condyle and articular disc traversing the contour of the glenoid fossae
