Q

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

A

balanced occlusion (both cusps touching)

18
Q

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

A

compensating curve

19
Q

decreasing the anterior guidance angle:

A

will facilitate establishing balanced occlusion

20
Q

hanau’s quint

A

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

21
Q

5 factors that affect balanced occlusion

A
  1. condylar inclination
  2. incisal guidance
  3. occlusal plane inclination
  4. compensating curve
  5. cuspal inclination
22
Q

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

A

excursive movements

23
Q

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

A

balanced occlusion

24
Q

setting flat/hitting on one side and not the other

A

non-balanced

25
Q

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

A

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

26
Q

condylar guidance is determined by

A

the patients anatomy

27
Q

monoplane occlusion indications:

A

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

28
Q

ideal ridge forms

A

square to gently round

29
Q

unfavorable ridge forms

A

thin, tall, undercut

30
Q

tuberosities
ideal=
minimum=

A

ideal=5-6
minimum= 4

31
Q

soft palate.
class I
class II
classIII

A

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

32
Q

border attachments

ideal=
unfavorable=

A

ideal= muscle/frenum attachments are 10 mm or more from crest of ridge

unfavorable= attachments near crest of ridge may interfer with peripheral seal

33
Q

the tongue and complete dentures major impact areas:

A

border seal
tooth placement
speech

34
Q

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

with what

A

retruded tongue

35
Q

chewing efficiency is ____% of natural teeth

A

20-25%
