L1 - Intro

Question 1

definition of excellent prognosis

Answer 1

no bone loss, excellent gingival condition, good patient cooperation, no systemic environmental factors

Question 2

definition of good prognosis

Answer 2

one or more of the following
- adequate remaining bone support, adequate possibilities to control etiologic factors and establish a maintainable dentition, adequate patient cooperation, no systemic environmental factors or well controlled systemic factors

Question 3

fair prognosis

Answer 3

one or more of the following

• less than adequate remaining bone support, some tooth mobility, grade I furcation involvement
• adequate maintenance possible, acceptable patient cooperation, presence of limited systemic/ environmental factorss

Question 4

poor prognosis

Answer 4

one or more of the following
- moderate to advanced bone loss, tooth mobility, grade I and II furcation involvments, difficult to maintain areas and or doubtful patient cooperation, presence of systemic / environmental factors

Question 5

questionable prognosis

Answer 5

one or more of the following: advanced bone loss, grade II and III furcation involvments, tooth mobility, inaccessible areas, presence of systemic / environmental factors

• provisional prognosis allows the clinician to initiate treatment of teeth that have a doubtful outlook in the hope that a favorable response may tip the balance and allow teeth to be retained

Question 6

individual tooth prognosis

Answer 6

determined AFTER the overall prognosis and is affected by it

ex- in a patient with a poor overall prognosis, the dentist likely would not attempt to retain a tooth that has a questionable prognosis because of local factors

Question 7

local factors

Answer 7

1. plaque/ calculus
2. restorations
3. furcation involvment
4. root concavitites/ proximity
5. short roots
6. tooth mobility

Question 8

prosthetic / restorative factors

Answer 8

1. caries
2. non-vital teeth
3. root resorption
4. abutment selection

Question 9

degree on condylar inclination on semi-adjustable

why?

Answer 9

25 degrees

majority of the population has condylar guidance > than 25

so clear or prevent contacts at 25 degrees will not caue any premature contacts intra-orally

Question 10

using articulator when

Answer 10

when excursive movements need attention in tx (almost always)

all fixed partial denture work

complete and partial dentures because worried abot dynamic occlusion

occlusal equilibration on a posterior reconstruction or post orthodontic tx or a full arch/ mouth reconstruction

Question 11

ondylar inclincation more than 25

Answer 11

then when go into protrusive – dont get interferences

Question 12

positive error

Answer 12

error on the occlusal surface is one which occurs when the articulator undercompensates for the mandibular movement, resulting in a positive feature existing on the occlusal surface where that feature should be similar or non-existent

• a cusp tip or ridge that is too high or one that in in the path of an opposing ridge or tip during a mandibular excursion

Question 13

negative error

Answer 13

occurs when the articulator over compensated for a mandibular movement

Question 14

negative and positive error

Answer 14

classification of errors in occlusal restorations fall into these two categories (positive and negative)

Question 15

balanced occlusion usually in

Answer 15

denture patients

can have contact on both sides during excursive movements?

Question 16

MIP usually used for

Answer 16

preferred postion for smaller restorations - like crowns and 3 units ** only if hand articulated and have posterior teeth / dentate patients

Question 17

class I usually ___ vertical overlap

Answer 17

no more than 2mm vertical overlap

Question 18

class II div 1 and 2 overlap?

Answer 18

usually 100 %

Question 19

class III usually are

Answer 19

edge to edge

Question 20

harder to restore 3 unit bridge with canine guidance or group function

Answer 20

group function – more teeth to worry about and occlusion on the bridge as well if canine guidance was there - no intererences exist on that side)

Question 21

why canines good

Answer 21

canines suited to take EXCURSIVE movements

• long and largest roots
• excellent crown to root ratio
• set in dense bone

sensory input of the anterior teeth

Question 22

u of shimstock and other one we use for crowns? dentures?

Answer 22

8 u for shimstock
- does not mark but can see how tight something is - like slide it through

21 u – corwns

100 u - denture us e

Question 23

size of contact

Answer 23

the larger the size of the marking – the larger the contact area

Question 24

intensity of contact

Answer 24

the darker the spot – the more likely it is a heavier contact

halo / bullseye contacts are heavy contacts

Question 25

contacts on inclines

Answer 25

no - dont want that

on cusp tips and surfaces

Question 26

supporting cusp aka

Answer 26

functional – centric cusp

Question 27

guiding cusp

Answer 27

aka non-centric - guiding / balancing- shearing

Question 28

BULL rule works well for?

Answer 28

denture patients

Question 29

BULL rule?

Answer 29

modifications should be made when adjusting occlusion to the buccal cusps of the upper posterior teeth and the lingual cusps of the lower posterior teeth

Buccal Upper Lower Lingual

Question 30

pre-mature contact in CR or MIP but NOT eccentric adjust?

Answer 30

the opposing central fossa

Question 31

example - palatal cusp of maxillary first contacts pre-mature in MIP and woring movement but not non-working adjust where?

Answer 31

have to adjust that cusp

Question 32

if premature contacts occur between the two non-opposing supporting inner inclines of functional cusps?

Answer 32

trim the inner inclince of the mandibular functional cusp - until this contact has been moved to the opposing cusp leaving a tip contact

then

trim the inner incline of the maxillary functional cusp until the maxillary supporting cusp tip contacts its opposing fossa or marginal ridge

Question 33

if premature contacts occur between the two non-opposing supporting inner inclines of functional cusps?

Answer 33

trim the inner inclince of the mandibular functional cusp - until this contact has been moved to the opposing cusp leaving a tip contact

then

trim the inner incline of the maxillary functional cusp until the maxillary supporting cusp tip contacts its opposing fossa or marginal ridge

Question 34

pre mature contact in mip working and non-working

Answer 34

need to adjust that functional cusp

Question 35

major rule for adjusting occlusion - especially in dentate patients

Answer 35

ALWAYS CHECK IN EXCURSIONS BEFORE ADJUSTING

Question 36

KIND OF CONTACT WE WANT

Answer 36

cusp tip to surface contact

Question 37

when do we want bilaeral and simultaneous contacts?

Answer 37

in MIP or centric

not in non-working / working for patients with teeth
