occlusion glossary

Question 1

CLass I

Answer 1

ideal relationship of post teeth when mesiobuccal cusp of the maxillary first molar is centered on the buccal groove of the mandibular first molar

Question 2

Class II

Answer 2

mandibular dental arch is posterior to the maxillary arch in one or both lateral segments
mandibular first molar is distal to the maxillary first molar compared to the ideal class I relationship

Question 3

Class III

Answer 3

mandibular dental arch is anterior to the maxillary dental arch in one or both lateral segments
mandibular first molar is mesial to the maxillary 1st molar

Question 4

the relative position of teeth to form a curved or U shape configuation viewed from the occlusal surface

Answer 4

Arch alignment

Question 5

the angle formed between the sagital plane and the average path of the non-working condyle, as viewed in the transverse plan during lateral movements

Answer 5

bennett angle

Question 6

where is balanced articulation is gound

Answer 6

heavily worn teeth and complete dentures

Question 7

Centric Cusps

Answer 7

the functional cusps

Question 8

tooth to tooth occlusion

Answer 8

cusp-fossa occlusal scheme

Question 9

tooth-to-two-teeth occlusion

Answer 9

cusp-marginal ridge occlusal scheme

Question 10

any surface whichdiverts the mandible from its intended movement

Answer 10

deflective occlusal contact

Question 11

movement occurring when the mandible moves away from maximal intercuspation

Answer 11

excursive movement

Question 12

the amount by which the incisal edges of the maxillary anterior teeth are labial to the incisal edges of the mandibular teeth at maximal intercuspation. the projection of teeth beyond their antagonists in the horizontal plane

Answer 12

Horizontal overlap (overjet)

Question 13

The position of the mandibular teeth (or tooth) relative to the maxillary teeth (or tooth) when the teeth are maximally occluded

Answer 13

interarch tooth alignment

Question 14

The mediolateral movement of the mandible when viewed in the frontal plane

Answer 14

mandibular translation(sideshift, bennett movement)

Question 15

what is the early part of mandibular translation

Answer 15

the greatest portion occurs early in the first 4 mm of forward movement of the non-working condyle as it leaves centric relation

Question 16

what occures during immediate mandibular translation

Answer 16

the translatory portion of lateral movement in which the non-working condyle moves essentially straight and medially as it leaves the CR possition

Question 17

what occures during progressive mandibular translation

Answer 17

the translatory portion of the mandiblar movement viewed in the transverse plane that occurs at a rate or amount that is directly proportional to the forward movement of the non-working condyle

Question 18

the side of the mandible that moves towrad the median line in lateral excursion

Answer 18

non-working side

Question 19

an occlusion which exists in the absence of signs and symptoms of occlusion related pathosis. Acceptability of occlusal variation and a sense of physchological and physical patient comfort are implied

Answer 19

physiological occlusion

Question 20

the relation of the mandible to the maxillae at the instant of tooth contact following clsure about the transverse horizontal axis

Answer 20

retruded contact position

Question 21

the side towards which the mandible moves or is displaced. assume movement or displacement is away from maximal intercuspation

Answer 21

working side
