Q

what is a reversible hydrocolloid?

A

heat reverses its form

41
Q

Alginate

A

irreversable hydrocolloid, extracted from brown seaweed, hydrophilic so moist surfaces arnt a problem, fill tray with 3mm of paste and dissinfect with iodophor, bleach or a glutaraldehyde.

42
Q

how to disinfect an alginate impression

A

wrap it in a soaked paper towell in a sealed plasatic bag for 10 min.

43
Q

how long should the stone cast and impression stay inact?

A

minimum of 30-60 min.

44
Q

2 things that affect the shelf life of alginate impression materials

A

storage temperature andmoisture contamination of ambient air

45
Q

whats a diagnostic cast?

A

the first step of preposthetic surgery. This is studied to determine the amount of surgery needed if needed at all.

46
Q

Making the diagnostic cast

A

pour within 15 mins of making the impression. Dental plaster is usually used because its cheap

47
Q

why are casts poured in 3 pours?

A

1st- liquidy to get in all the grooes
2nd- a little thicker
3rd- is for the base

48
Q

whats the first part of the process of making a custom tray

A

make an impression, then make a stone cast. Use resin dough ( triad) around the cast and cut is short 2mm above the vestibule, give the frenum 1 mm of clearence

49
Q

why must someone block out the undercuts?

A

to make sure the custom trays dont get stuck. Make sure you dont over block out eiter

50
Q

what does the air barrier do?

A

hardens the tray.

51
Q

after the tray is hard whats next?

A

trim the borders so theyre smooth. Then you border mold

52
Q

whats the purpose of the border mold?

A

it helps create a suction

53
Q

which custom tray do you drill a hole in?

A

maxillary, this allows pollysulfide to flow out

54
Q

before putting the polysulfide filled tray on the cast, what must you put on the cast?

A

2 coats of Al- Cote, this allows it to come off easier.

55
Q

tightly attached mucosa

A

covers the crest of the residual ridge and the anterior 2/3 of the palate, When compressed it rebounds and dislodges the denture,

56
Q

loosely attached submucosa

A

covers the soft palate and lines the vestibules, pressure is not passed to the supporting bone, forms the denture border seal

57
Q

differentiated mucosa

A

posterior 1/3 of the hard palate and retromolar pad, pressure is directed on the boney support

58
Q

what does the different colors( white, gray, gree, red, black) mean in impression compounds?

A

white has the lowest melting temperature and black has the highest.

59
Q

what is tissue rest?

A

before putting dentures in you need to let the tissue recover for at least 24 hours.

60
Q

tissue manipulation for maxilla impression

A

patient moves mandible side to side for maxillary impression ( this involves slight manipulation of lips and cheeks)

61
Q

tissue manipulation for mandible impression

A

hold tray in position while patient puckers lips and lifts and moves tongue around

62
Q

whats the purpose for boxing?

A

to make a base and preserve vestibular contours of the final impression

63
Q

How do you make a final impression?

A

1:1 ratio of pumice and plaster. Mix the powders together first then add water ( at lecom we just use plaster)

64
Q

what must you put on before the red boxing wax?

A

sticky wax

65
Q

how thick should the base of the cast be?

A

9-15mm, if its thinner it can break easier, if thicker it doesnt fit in the processing flask

66
Q

the finished microstone cast should have what lenght in the landing area and vestibular depth?

A

landing area -9mm

vstibular depth- 2mm

67
Q

whats a record base?

A

temporary device representing the base of the denture and used for making jaw relation records. ( not part of final denture)

68
Q

whats the neurtral zone?

A

where there is no forces applied to the denture

69
Q

what are occlusal rims used for?

A

determine the neutral zone, establish level of occlusal plane, make maxillomandibular relation records

70
Q

when using the triad for a record base do you cut 2mm short of vestibule?

A

no, go to the depth of the vestibule( remember to block out undercuts)

71
Q

whats used to make the wax occlusion rims?

A

dental wax/ base plate wax, ( pink stuff)

72
Q

what is baseplate wax made of?

A

75% paraffin or ceresin, beeswax, other waxes

73
Q

Important factors to consider making occlusison rims

A

use sticky wax to attach the base plate wax, fold base plate wax many times, anterior segment of maxillary is slightly flared labially

74
Q

whats the distance of the incissive papilla and labial surface of central insicor of baseplate model?

A

5-8mm

75
Q

when fully occluded the 2 basplates measure what?

A

40mm ( 22 for maxillary, 18 for mandibular)

76
Q

occlussal rim thickness by the incisors, premolars, molars should be what

A

incisors-3-5mm
premolars- 5-7 mm
molars- 8-10 mm

77
Q

where is the frontal axis?

A

right through the middle of your face between the central incisors

78
Q

where is the sagittal axis?

A

passes the TMJ and extends. both ways.

79
Q

What are the 2 basic types of movement in the jaw?

A

rotation and translation. Rotation happens before the translation

80
Q

know what is happening during each border movement

A

Centric relation, maximum intercuspation, edge-to-edge incisal, maximum protrusion, maximum opening

81
Q

terminal hinge axis position

A

where the mandible stops before it starts translation.

82
Q

maximum protrusion position

A

most anterior position

83
Q

edge to edge contact

A

where incisors from both arches are edge to edge

84
Q

what is mandibular opening?

A

line going from maximum protrustion to maximum opening

85
Q

what does the articulator do?

A

reproduces the movement of te jaws, Maintains the relationship of the maxilla and mandible to the condys

86
Q

what 3 types of records are used to transfer maxillomandibular relationships in a edenticulous patient?

A
  1. interocclusal relationhsips
  2. graphic records
  3. hinge-axis records
87
Q

what measurements are used to get interocclusal relationships?

A 
condylar guidance( condyle to eminence)
bennett shift( medial to lateral)
88
Q

describe the bennet shift

A

Lateral shift of the mandible

89
Q

graphic records

A

recording movements between the static interocclusal records. This isnt possible in the edentulous patient because the recording devices are not firmly fixed to the riedges and may move

90
Q

what are hinge- axis records?

A

the arc of the jaw as it opens and closes( facebow)

91
Q

overjet and overbite relationships determine what?

A

phonetics and esthetics

92
Q

what is vertical dimension

A

the distance between the mandible and maxilla when the dental arches are in maximal intercuspation

93
Q

what is centric occlusion?

A

maximal intercuspation of teeth. Specifically the relationship of the maxilla and mandible while teeth are in maximal contact

94
Q

what is centric relation?

A

is the position of the mandible while in its most superioanterior position. This is where the condyles articulate with the thinnest avascular portio of their respective disks. ( this position is independent of tooth contact)

95
Q

is malocclusion strictly dental?

A

no it can be skeletal as well

96
Q

who was the father of malocclusion?

A

edwar hartley angle

97
Q

malocclusion type 1

A

the relationship of the first molars is normal and the upper and lower jaws are in a normal relationship
to each other, but the other teeth are crowded, irregularly spaced, or overlapped.

98
Q

malocclusion type 2

A

the lower molars fit the upper molars, but are not in correct position. The bottom jaw grows into a more backward position than normal.

99
Q

malocclusion type 3

A

occurs when the lower molars are too far forward and don’t fit into the upper molars.( usually most complicate and difficult to correct
