Answer 2

CR

Question 3

master casts are articulated after

Answer 3

using CR records

Question 4

Answer 5

articulation

Question 6

the static relationship between the incising and masticating surfaces of the max and mand teeth or tooth analogues

Answer 6

occlusion

Question 7

type of occlusions

Answer 7

monoplane/neutrocentric
lingualized
balanced

Question 8

occlusal arrangement where posterior teeth have masticatory surface that lack any cuspal height

Answer 8

monoplane occlusion

Question 9

posterior teeth have no cusps and teeth are arranged on flat surface

Answer 9

monoplane occlusion

Question 10

no vertical overlap of anterior teeth

Answer 10

monoplane occlusion

Question 11

occlusion when patients will have to conform to a vertical pattern of mastication

Answer 11

monoplane occlusion

Question 12

severely resorbed ridges

Answer 12

monoplane occlusion

Question 13

skeletal class II, III jaw relations and crossbites

Answer 13

monoplane occlusion indications

Question 14

-posterior teeth on the working side are contacting
-posterior teeth on the non-working (balance side) are not contacting

Answer 14

monoplane occlusion (NON-balanced)

Question 15

cuspless mandibular posterior teeth arranged on a flat plane
-only max lingual cusps are in occlusion with central fossae areas of mand post teeth

Answer 15

lingualized, non-balanced occlusion
-all the advantages of the monoplane occlusion and improved esthetics

Question 16

least esthetic scheme and limiting on the arrangement of anterior teeth
-difficult in food penetration

Answer 16

monoplane occlusion disadvantages

Question 17

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

Answer 17

balanced occlusion (both cusps touching)

Question 18

the ant-post and mesial-lingual curvature of occluding surfaces and incisial edges of artificial teeth used to devleop balanced occlusion

Answer 18

compensating curve

Question 19

decreasing the anterior guidance angle:

Answer 19

will facilitate establishing balanced occlusion

Question 20

hanau’s quint

Answer 20

C=(condylar inclination) x (incisial guidance) / (occlusal plane) x (cuspal inclination) x (compcurve)

Question 21

5 factors that affect balanced occlusion

Answer 21

1. condylar inclination
2. incisal guidance
3. occlusal plane inclination
4. compensating curve
5. cuspal inclination

Question 22

occlusal contacts are made on anterior teeth only in_______ in the attempt to minimize stress/force applied to anterior ridge

Answer 22

excursive movements

Question 23

the bilateral, simultaneous, anterior and posterior occlusal contact of teeth in centric relation and eccentric relation

Answer 23

balanced occlusion

Question 24

setting flat/hitting on one side and not the other

Answer 24

non-balanced

Question 25

hanau's quint: incisal guidance= condylar guidance= cusp height= plane of occlusion compensating curve

Answer 25

incisal guidance= anterior influence condylar guidance= posterior influence/determined by patient anatomy cusp height=0, 20, 30 plane of occlusion= compensating curve=excursive movement

Question 26

condylar guidance is determined by

Answer 26

the patients anatomy

Question 27

monoplane occlusion indications:

Answer 27

-excessive inter-ridge -skeletal class II, III and crossbite -successful previous F/F were monoplane -limited oral dexterity -severely resorbed ridges

Question 28

ideal ridge forms

Answer 28

square to gently round

Question 29

unfavorable ridge forms

Answer 29

thin, tall, undercut

Question 30

tuberosities ideal= minimum=

Answer 30

ideal=5-6 minimum= 4

Question 31

soft palate. class I class II classIII

Answer 31

I= ideal >5mm II= okay 3-5 mm III= poor <3 mm (hardest to work with

Question 32

border attachments ideal= unfavorable=

Answer 32

ideal= muscle/frenum attachments are 10 mm or more from crest of ridge unfavorable= attachments near crest of ridge may interfer with peripheral seal

Question 33

the tongue and complete dentures major impact areas:

Answer 33

border seal tooth placement speech

Question 34

border seal is absent, stabilizing influence of tongue is absent, rentention/function of mand CD difficult with what

Answer 34

retruded tongue
