what tongue actions are needed for the impression borders

mandibular impression borders: key actions: ask patient to raise their tongue to the roof the mouth, then anterior to vermilin border and then to the corners of the mouth. ask patient to swallow

how high should domed shaped teeth be?

1-2 mm above the tissue

for prefabricated fiber tapered posts where should you cut the post for desired length

the TOP

Adjust porcelain parts of crowns using either

a porcelain adjusting kit or a diamond

Is ytp silica or non silica based

Non silica based ceramic-the strongest

diode lasers are used for what

soft-tissue, low level therapy and laser whitening

Name the group of weaker ceramics

Silica based ceramics

leucite reinforced porcelains

empress esthetics

ideal width-to-length ratio of tooth

0.75-0.80

Name the group of Stronger ceramics

Non silica based oxides

NX3 cement is used for

Silica based cements

best predictors of lower denture success

lateral throat form | tongue position

Why do CAD/CAM complete dentures have superior strength and fit?

pre-polymerized acrylic resin blocks

increased crystallinity in strengthening ceramics often leads to

opacity-similar problem with metal

weaker ceramics require what

silane coupler and resin cement

recommendations to limit post operative tooth sensitivity

Literature recommends using plenty of cool water during preparation, and a light touch with sharp burrs. Application of Gluma or similar product and then a cavity liner.

how should implants be placed in the maxillary anterior region labiolingually

2mm lingual to labial bone surface

full contour cermamics must be

translucent material

implant diameter of canines in maxillary

around 4 mm

the degree of whiteness of the enamel

value

when adjusting a crown, alloy surfaces should be adjusted with what

carbide finishing burr

prefabricated metal posts should use what cementation

rely x luting

gluma treats what and its mode of action

dentin hypersensitivity/protein precipitation/tubule occlusion

color saturation of the dentinal body

chroma

nd: yag lasers are used for what

soft tissue only

Name the group of strong cements

Composite based

Adjust Zirconia Crowns with the

Zirconia | adjusting kit only

dentin hypersensitivity can result

when fluid inside the dentinal tubules moves inward/outward

Name a composite cement with light dual cure with adhesive

NX3

what retains a denture primarily?

primarily interfacial surface tension

Name three silica based ceramics

Feldspathic porcdlain Leucine reinforced Lithium dilisicate

DJUSTMENTS CAUTION: Make no internal adjustments to crowns

porcelain, ceramic or monolythic Zirconia crowns. WHY? Internal interferences of these types of crowns will require a remake.
