Q

coupland’s elevators

A

3 sizes
bigger number= wider tip
half tip of universal
in correct place & rotate correctly can elevate tooth
if used incorrectly will damage adjacent teeth

Q

cryer’s elevators

A 
par
when holding concave surface facing ceiling, pointing up
right hand= right, left hand = left
point toward each other
to elevate root
eg fractured root
rotate to lift
22
Q

warwick james elevators

A 
pair
like cryers also straight
small couplands
-elevating lower wisdom teeth, small
hold in hands w/ concave facing ceiling, pointing at each other
pointy, but less
23
Q

what are upper roots used for?

A

roots

24
Q

what are upper straights used for?

A

centrals, laterals, canines

25
Q

what are upper left & right used for?

A

molars

26
Q

what are upper 3rd molar bayonette used for?

A

8’s

27
Q

how do you know the difference between upper root and upper universal?

A

upper root have thinner beak than upper universal

28
Q

how do you know the difference between upper straights and upper universal?

A

straights handle in line with beak, forceps straight from handle to tip
universal curved handle and beak at angle to handle

29
Q

what are lower roots used for?

A

retained roots

30
Q

what are lower universals used for?

A

incisors, canines, premolars

31
Q

what are lower molars used for?

A

molars

32
Q

what are lower cowhorn used for?

A

broken down molars

33
Q

how do you tell the dif between lower root vs universal?

A

hold side by side

root much thinner beak

34
Q

how do you tell the dif between lower cowhorn vs molar?

A

hold side by side
cowhorn thin, pincer like beak to get into furcation
molar pointed beak to engage furcation

35
Q

how should a patient be positioned for upper teeth?

A

comfortable height
supine position
45-90 degrees

36
Q

how should a px be positioned for lower teeth?

A

more upright position

0-45 degrees

37
Q

how should the operator be positioned for LR?

A

behind right shoulder

38
Q

how should the operator be positioned for UR, UL, LL?

A

stand in front

on px right side

39
Q

describe extraction technique

A

ensure soft tissues clear of forceps
apply forceps as far down root as possible w/o traumatising gingivae
place thumb and finger of left hand on alveolar bone for support
apply apical pressure
apply movements for extraction
if lower molar support mandible

40
Q

what are the movements for extraction for a multirooted tooth eg molar?

A

figure 8

41
Q

what are the movements for extraction for a single rooted tooth?

A

rotation

42
Q

what are the movements for extraction for multi-rooted premolars?

A

rotation

43
Q

what should you do post-extraction?

A

check tooth apices are intact
check if socket clear
if retained root/bone easy to remove then do so
if not easy call for help
place dampened gauzze in site and as px to bite
leave 5-10 mins then check haemostasis achieved
give post-op instructions
get checked

44
Q

what are luxators used for?

A

to sever and tear pdl

create mobility

45
Q

describe the tip of a luxator

A

rounded

46
Q

what are elevators used for?

A

create space

47
Q

how are elevators used?

A

wedge, lever or wheel/axel

48
Q

describe the tip of an elevator

A

sharp

49
Q

describe warwick james elevators

A

left, straight, right
point inwards
good for wisdom teeth

50
Q

describe cryers elevators

A

left, right

point inwards useful in furcation of molars

51
Q

how should you hold an elevator/luxator

A

palm of hand
curl thumb and fingers round handle
index finger on shank for support & control

52
Q

how should you use a luxator

A

position same as forceps
place left thumb and finger on alveolar bone
-supports bone, prevents fracture, retracts tissues, supports mandible
luxate in buccal sulcus from mesial to distal
