Do we mount teeth in max/mand casts before or after the esthetic try in?

Back 12

before

Front 13

Do we mount teeth in max/mand casts before or after the preliminary try in with the RBOR?

Back 13

after - need to establish VDO, CR first

Front 14

3 components of dentogenics

Back 14

SPA - sex, personality, age

Front 15

Guides that can be used to help select denture teeth

Back 15

dx casts of natural teeth, residual ridges' size, anthropoetric measurements, photographs of their natural teeth, radiographs relatives' teeth, marks on max. rim indicating relaxed CORNERS of the mouth, previous Dentures [CRAP uXoRiCiDe]

Front 16

Do males have sharp or blunt canines

Back 16

blunt

Front 17

Do females have sharp or blunt canines

Back 17

sharp

Front 18

Which gender has the anterior teeth closely follow the lower lip?

Back 18

females (not a lot of mand anteriors showing with smile)

Front 19

3. TF The high smile line scribed into wax of the maxillary occlusion rim usually indicates the minimum incisogingival height of the mx. anterior teeth

Back 19

TRUE

Front 20

4. TF The factors of age, sex, personality [SPA] are scientifically proven to help develop an esthetically pleasing denture.

Back 20

false - no scientific studies

Front 21

6. What governs the overall MD width of mand posterior teeth?

Back 21

amnt of space available from distal end of canine to beginning slope of retromolar pad

Front 22

10. What are the most common tooth selection errors in shad and size?

Back 22

too light in shade and too small in size

Front 23

How do we determine width of the 6 anterior teeth

Back 23

measure from commissure marks on wax rim

Front 24

Anterior ridge relationship affects canine alignment, so for CLASS II pt, we use narrower or wider mandibular teeth than recommended by pamphlet guide?

Back 24

narrower canines for class II

Front 25

Anterior ridge relationship affects canine alignment, so for CLASS III pt, we use narrower or wider mandibular teeth than recommended by pamphlet guide?

Back 25

shorter/wider canines for class III [cuz they gotta go so far back]

Front 26

List the steps in selecting teeth from the BlueLine Form Selector

Back 26

1. Width of maxillary anteriors; 2. Form (soft/bold); 3. length of teeth [V fingers on maxilla, then corners of mouth (eatin poon), then flip sideways]

Front 27

Most important factor in selecting tooth color for pt is...

Back 27

pt desires! this is NOT scientific. also based on complexion, age. However, not too light nor not too dark is scientifically proven... p.14?

Front 28

TF Setting teeth on the residual ridge usually provides adequate lip support.

Back 28

FALSE - teeth on ridge will NOT provide lip support (mx incisors' gingival 1/3 suppors lips)

Front 29

TF The smile line follows the contour of the upper lip.

Back 29

FALSE - lower lip since the upper lip stays fairly straight

Front 30

which group has the greatest smile line curvature

Back 30

young, nubile females

Front 31

which group has the least smile line curvature

Back 31

older males

Front 32

TF The long axis of the lateral should be inclined more mesially than that of the central

Back 32

false - distal inclination of long axis of lateral

Front 33

TF The long axis of the lateral should be inclined more distally than that of the canine

Back 33

false - canine is more distaly inclined than lateral

Front 34

1. For most patients, when considering the arrangement of the maxillary anterior teeth, what determines esthetics? What determines the fullness of the lips (lip support)?

Back 34

incisal 1/3 of max ant determine esthetics; cervical (necks) determien lip support/fullness

Front 35

3. Alterations of the maxillary lateral incisors can he made to help create a more natural-appearing denture. What changes might he considered?

Back 35

1. long axis inclination; 2. incisal edges up; 3. tooth width; 4. gingival margins; 5. tooth shade; 6. shapes of incisal edges, angles, proximal surfaces

Front 36

4. The alignment of the canines is important from an esthetic standpoint. How should canines he arranged in comparison to the central and lateral incisors?

Back 36

long axis of max. canine should have distal inclination with prominent necks; distal half shouldnt be visible when looked at from front

Front 37

5. Why is it important to minimize the vertical overlap of the anterior teeth when arranging these teeth for a balanced occlusion?

Back 37

minimize separation of posteriors during excursives, simplifying arrangement of teeth
