Q

Where are cowhorn forceps sput?

A

Down into furcation and we squeeze handle which goes into furcation and lifts tooth out (normal technique is mobilising teethe then extract with forceps)

wHEN EXTRACTING TEETH WHEN do we stand behind pt?
lower molars - right lower pre molars - right
26
What position are we in to extract upper 1-5?
Infront of pt to the right
27
What forceps can we use to extract upper 1-5?
Straight upper anterior forceps Upper universal forceps
28
What position are we in to extract upper molars?
To the front and to the right but have pt a little bit more backwards
29
What forceps can we use to extract upper molars?
Upper molar forceps (r or left) Upper bayonet third molar forceps upper bayonet root forceps if the root fractures
30
What position are we in to extract lower molars on left hand side?
in front of pt to the right hand side - chair slightly reclined
31
What forceps do we use to extract lower left molars?
Lower molar forceps Cowhorn forceps - if two root s
32
What position are we in to extract lower right molars?
behind pt to the right
33
What forceps do we use to extract lower right molars?
Lower molar forceps - R Cowhorn forceps
34
What position are we in to extract lower left pre molars?
Infrotn and to right
35
What forceps do we use for lower left pre molars?
Lower universal forceps
36
What position are we in to extract lower right pre molars?
behind and to right
37
What forceps do we use to extract lower right pre molars?
lower universal forceps
38
What forceps do we use to extract lower anterior teeth?
Lower universal forceps
39
what position are we in to extract lower anterior teeth?
infront to right or behind pt to right
40
What position should pt be in for upper extractions?
Pt up high with pts head level to our shoulders we stand to the front and right of the pt
41
How should our elbows and arms be when extracting tooth?
straight as possible
42
When extracting tooth what do we use non dominant hand for?
To support alveolus with thumb and index finger
43
In teeth 1-5 what movement do we use?
primary rotational movement `(cork bottle) then secondary buccal to palatal movement to dilate the socket and deliver the tooth
44
Why do we use buccal to palatal movement?
to dilate the socket and deliver the tooth
45
What movement do we use in molar teeth?
Additional figure of eight movement
46
Describe how to extract an upper right canine
position ourselves infant and to right of patient take the straight upper anterior forceps or upper universal forceps use non dominant left hand to retract the soft tissues and support the alveolus then begin with apical pressure to ensure blades of forceps are on root surface primary rotational movement (cork screw movement) buccal to palatal movement
47
Describe how to extract upper left 2nd premolar
position ourselves infrotn and to right of pt select upper universal forceps use non Dom hand to supportr soft tissue and alveolus primary rotation movement secondary buccal to palatal movement deliver tooth
48
How do we extract an upper 1st molar?
Infront and to right of pt select upper molar forceps use non Dom hand to support soft tissues and alveolar (thumb and index finger) ensure upper molar forceps were BEAK TO CHEEK!!!! apply firm apical pressure primary rotational movement secondary buccal to palatal additional figure of 9 socket movement to deliver tooth
49
What is different with chair position for lower extractions?
it is more reclined and low so pts head is level with our elbows
50
For lower right quadrant where do we stand when xla?
behind and to right of pt
51
For lower left quadrant where do we stand when xla?
infront and to rigtht of pt
52
What do we use non Dom hand for?
thumb and index fingers for alveolus and remaining fingers for mandible
53
Describe how to extract a lower right canine
Stand behind pt to the right t select lower universal forceps position non Dom hand primary rotational secondary buccal to lingual movement
54
Describe how to extract lower right 2nd molar
stand behind pt to right select lower molar forceps (r) or cowhorn forceps non dom hand apply forceps with firm apical pressure initial primary rotational movements secondary buccal to lingual additional figure of 8 movements to widen and dilate socket
55
How do we extract lower left canine?
infrotn and right of pt select lower universal forceps non dom hand apical pressure primary rotational movement secondary buccal to lingual
56
What are elevators?
these are used to loosen the tooth elevator instruments are used to luxate teeth, and this technique imparts forces to tooth particles that sever the periodontal ligament around tooth roots inside the socket and expand alveolar bone around tooth particles. LUXATE THE TOOTH and minimise how much we break teeth
57
What are the three types of elevators?
couplands cryers Warwicks
58
What are couplands elevators?
These are 3 different sized elevators that are used to split multi rooted teeth and are inserted between the bone and tooth roots and rotated to elevate them out of the socket
59
What are the sizes of couplings?
1 2 3 narrow to wide
60
What are cryers elevators?
Set of two pointed instrument - concave surface points to ceiling upwards (pointy bits will paint at each other)
61
What are cryers used for?
to get out fractured retained roots
62
What are the two cryers?
left and right
63
What are Warwick James elevators?
set of 3 elevators - left right and straight
64
What is straight warwkicj used for ?
lower wisdom teeth
65
How is couplings elevator held?
iN PALM OF HAND AND INDEX FINGER SUPPROTS THE SHANK
66
what movement for couplands elevator?
rotational movement
67
What shaped blade does cryers have?
triangle
68
What are cryers good for extracting?
molar roots
69
Where can cryers be applied?
Buccal to engage furcation or placed in socket to elevate fractured root
70
wHAT CAN R and l Warwickjames be good for?
Elevatign maxillary 3rd molars
