Q

Describe the upper universal forcep

A

Slight curve
Handle lifts off the table
Curve allows you to reach further back in the mouth
Tip of instrument is identical to the straight upper anterior forecep

Q

Describe the upper molar forceps

A

Tips have a concave surface on either side

Concave surface fits on the convex part of the root, grab it and mobilise it

A

there is a smooth end on one site - for the palatal root (only 1 of these)

Q

How do most forceps work

A

by giving a good grip to allow movement and make the tooth more mobile
want a nice deep grip

Q

How do cowhorn forceps work

A

it provides a squeezing action as the two points go into each other and elevate the tooth
requires divergent roots

16
Q

Why do cowhorn forceps work better in younger people

A

softer bone

17
Q

What makes cowhorns unsuitable for the usual method of extraction

A

they are smooth

don’t provide a good grip

18
Q

What are the two bayonet forceps

A

upper bayonet forceps (third molar forceps)

upper bayonet root forceps

19
Q

What is the pattern seen on a bayonet forceps

A

Z shape

allows for better access

20
Q

What is the upper bayonet root forceps good for

A

removing fractured roots

21
Q

Why can we not use normal forceps for upper wisdom teeth

A

Upper wisdom tooth pattern is very variable - forceps cannot engage furcations because so variable so they are universal

22
Q

Where do you stand to take teeth out on the lower right hand side

A

right hand side

behind px

23
Q

Where do you stand to take teeth out on the lower LHS

A

RHS of patient

in front of patient

24
Q

Where do you stand to take teeth out on the upper molars

A

RHS of patient
infront
px more upright

25
Q

What do elevators do

A

These isntruments loosen the tooth to make it easier to extract and even if the crown breaks the roots are more mobile

26
Q

What are the two couplands elevators

A

2 and 3

27
Q

Describe coupland’s elevators

A

Concave surface
Bit sharper at the end
Tear PDL and increase PD space and elevate the tooth

28
Q

What are the cryers elevators

A

Cryers are always paired together
pointy and curved
good for getting retained roots and little fractures and to elevate the root

29
Q

How can you tell which Cryer is right and which is left

A

Hold them so that concave surface is pointing wards the ceiling
The pointy bits need to be pointing at each other
The one in each arm is the corresponding arm

30
Q

What are the Warwick James elevators

A

straight
right
left
set of 3

31
Q

Describe Warwick james elevators

A

Curved but less pointy

Used for wisdom teeth as they are smaller and so better for narrower space of wisdom teeth
