Answer 1

22mm maxillary

18mm mandibular

Question 2

What are three purposes of space between the edentulous ridges

Answer 2

room to swallow, chew, and enunciate words
room for maxillary and mandibular baseplates
room to look and feel comfortable

Question 3

What is the chance that the baseplates with wax wins will fit the patients with out any alterations

Answer 3

slim

Question 4

This records all anatomic landmarks that should be covered by a denture and permits fabrication of properly extended custom trays that will expedite border molding and facilitate a quality impression.

Answer 4

an accurate preliminary cast

Question 5

This part of the pre-maxilla area must be visible

Answer 5

frenum notch

Question 6

These areas should not be cut short

Answer 6

retromolar pad areas and hamular notch areas

Question 7

These two areas should be flat and 13mm thick

Answer 7

maxillary palate and lingual tongue area

Question 8

All land areas of the cast should be how wide

Answer 8

3-4mm

Question 9

The cast in the tongue space should be reduced flat to access what

Answer 9

lingual undercuts

Question 10

this is added to the making of a custom tray to allow for a space that will accommodate at least a minimum 1mm thickness of supported impression material.

Answer 10

wax spacer

Question 11

The wax spacer stops the tray from doing what

Answer 11

over-seating into the soft tissues

Question 12

This is shaping of an impression material by the manipulation or action of tissues adjacent to the borders of an impression tray.

Answer 12

border molding

Question 13

What is the objective of border molding

Answer 13

to determine the contours, height, and width of the borders of the complete denture.

Question 14

Classical border molding of the peripheral borders of the custom tray is with this material

Answer 14

“green stick compound”

Question 15

We use this technique to make an impression of the vestibule during function; to manipulate the tissues to get them extended to allow maximum movement before engaging the denture and moving it.

Answer 15

selective pressure

Question 16

Always remember to do this to the green stick compound before placing it in the mouth

Answer 16

temper the compound to 140° water bath for 3-5 seconds

Question 17

The tray is completely immersed/tempered then immediately placed in the mouth so what

Answer 17

so it does not harden until after its in the mouth

Question 18

Which type of PVS can be used in place of the green stick compound

Answer 18

heavy body

Question 19

What should you take the final impression with

Answer 19

light body

Question 20

This will enclose the edentulous impression and preserve the vestibular contours of the final impression

Answer 20

a base

Question 21

What is the mixture for fabricating a base

Answer 21

1:1 plaster/pumice

Question 22

How much excess “racetrack” land area should there be around the base

Answer 22

4mm

Question 23

This is a substance, such as dried clay or cement, used to pack and seal pipe joints, and other connections or coat a porous surface in order to make it tight; can be used to seal boxing wax around the base while boxing it

Answer 23

lute (heal seal)

Question 24

Over-vibrating when pouring will cause what to happen

Answer 24

separation of wax

Question 25

You should not attempt this method to separate the final impression from the cast

Answer 25

the crow bar method; submerge in hot water for 15 minutes to aide in separation

Question 26

This an accurate replica of the residual ridge areas, and other parts of the dental arch upon which a complete denture prostehsis can be fabricated.

Answer 26

master cast

Question 27

The master cast must be protected by doing what before making the base plate

Answer 27

blocking out all undercuts

Question 28

What are two common problems of temporary base plates

Answer 28

not sufficiently blocking out all undercuts not sufficiently lubricating casts prior to making base plates can lead to a broken or marred surface of the cast

Question 29

What is the downfall of blocking out undercuts

Answer 29

lack of retention of the temporary base plate during patient treatment

Question 30

The occlusal rims are what

Answer 30

"wax pillars placed on baseplates"

Question 31

The occlusion rims are adjusted to record what

Answer 31

the patients interocclusal jaw relationship

Question 32

The occlusal rims serve as guides for what

Answer 32

setting the teeth in proper position and establishing the proper contours of the denture base

Question 33

These create temporary intermediate structural base-plates representative of contours of the final denture

Answer 33

templates/base plates
