Denture Occlusion

Question 1

The position of the mandible in which the condyles are in the most superior and anterior position in the articular fossae, resting against the posterior slopes of the articular eminences with the articular discs interposed.

Answer 1

Centric Relation

Question 2

Used as the reference position on which the casts are articulated•It is used because it can be verified and it is repeatable•It is a jaw position and it is independent of teeth position

Answer 2

Centric Relation

Question 3

The postural position of the mandible when an individual is resting comfortably in an upright position and the associated muscles are in a state of minimal contractual activity.

Answer 3

Physiologic Rest Position (other terms: Rest Vertical Dimension, Postural position)

Question 4

The distance between 2 selected anatomic or marked points when in maximal intercuspal position

Answer 4

Occlusal vertical dimension

Question 5

The distance between the Rest Vertical Dimension and the Occlusal Vertical Dimension.

Answer 5

Interocclusal Space (free-way space)

Question 6

The average plane established by the incisal and occlusal surfaces of the teeth

Answer 6

Plane of occlusion

Question 7

Orients the maxilla to the rotational axis in three planes•Using it will result in the path of opening (arc/path of opening) on the articulator being the same as the mandible has with the TMJ •Changes to the OVD can be made on the articulator if a face-bow record was used (and the casts have been articulated in CR)

Answer 7

Facebow

Question 8

The static relationship between the incising and masticating surfaces of the maxillary and mandibular teeth or tooth analogues.

Answer 8

Occlusion (definition)

Question 9

The static and dynamic contact relationship between occlusal surfaces of teeth during function.

Answer 9

Articulation (definition)

Question 10

Goals of _____•Minimize trauma to supporting structures•Preserve/maintain remaining structures•Promote stability of the dentures•Improve speech and esthetics•Restore mastication to a reasonable level

Answer 10

Occlusion for Removable Complete Prosthodontics

Question 11

What are the 3 types of occlusion used in CRM?

Answer 11

Monoplane, lingualized, balanced

Question 12

an occlusal arrangement where the posterior teeth have masticatory surfaces that lack any cuspalheight•Posterior teeth do NOT have cusps •Teeth are arranged on a flat plane

Answer 12

Monoplane occlusion

Question 13

Occlusal plane is parallel to the mandibular ridges and not related to the TMJ anatomy•Occlusal plane is completely flat; there is no curve of Speeor Wilson •No vertical overlap of anterior teeth •Patients will have to conform to a vertical pattern of mastication

Answer 13

Monoplane occlusion

Question 14

Occlusal forces are centralized over the ridges and lack of cuspalinclines results in a more forgiving occlusal scheme•Provides the patient more freedom in mandibular movements•Simpler technique in arranging prosthetic teeth and making occlusal adjustments

Answer 14

Monoplane occlusion

Question 15

Indications•Severely resorbed ridges•Skeletal class II, III jaw relations and crossbites

Answer 15

Monoplane occlusion

Question 16

Least esthetic scheme and limiting on the arrangement of anterior teeth•Difficulty in food penetration (cusplessteeth)???•Instability of prostheses in excursive movements and possibly in CR???

Answer 16

Monoplane occlusion

Question 17

In excursive movements with monoplane occlusion: posterior teeth on the working side are ______

Answer 17

contacting

Question 18

In excursive movements with monoplane occlusion: posterior teeth on the non-working side are ______

Answer 18

Not contacting

Question 19

Cuspless mandibular posterior teeth arranged on a flat plane •Only maxillary lingual cusps are in occlusion with central fossae areas of mandposterior teeth •All the advantages of the monoplane occlusion and improved esthetics

Answer 19

Lingualized, non-balanced Occlusion

Question 20

In _____ occlusion, Lingual cusps of maxillary posterior teeth are occluding with central fossae areas of mandibular posterior teeth (bilaterally)

Answer 20

Lingualized, non-balanced Occlusion

Question 21

Bilateral simultaneous occlusal contacts of the anterior and posterior teeth in excursive movements.

Answer 21

Balanced Occlusion

Question 22

The anterior-posterior and mesio-lingual curvature of occluding surfaces and incisal edges of artificial teeth used to develop balanced occlusion

Answer 22

Compensating curve

Question 23

_____ vertical overlap is easier for balanced occlusion

Answer 23

Increased vertical overlap

Question 24

Increased vertical overlap will lead to an _____ anterior guidance angle

Answer 24

Increased

Question 25

Increased horizontal overlap will lead to an _____ anterior guidance angle

Answer 25

Decreased

Question 26

_____ the anterior guidance angle will facilitate establishing balanced occlusion

Answer 26

Decreasing

Question 27

If you had to re-set bite, which cast must be remounted?

Answer 27

Mandibular

Question 28

How do you check speaking space?

Answer 28

S-sounds

Question 29

Which occlusion sets teeth with the curve of spee and wilson?

Answer 29

Balanced

Question 30

Which occlusion sets teeth on a flat plane; not much of a ridge

Answer 30

Monoplane occlusion

Question 31

What are the 5 parts to Hanau’s quint?

Answer 31

Compensating curve, condylar guidance, incisal guidane, occlusal plane, cuspal inclination

Question 32

Which of the 5 part of Hanau’s quint can’t be changed by dentist?

Answer 32

Condylar guidance

Question 33

Does the degree of teeth determine type of occlusion?

Answer 33

No

Degreed teeth describes the ___ of the ____ teeth

Answer 34
