Intro to Oral Surgery and Extractions Flashcards
MOPS
minor oral procedure surgery
what are the 2 indications for extractions
clinical
and/or (usually both)
radiographic
(in case of unusual anatomy)
10 reasons for unrestorable teeth that are indicated for extractions
Gross caries
Advanced periodontal disease
Tooth/root fracture
Severe tooth surface loss
Pulpal necrosis
Apical infection
Symptomatic partially erupted teeth
Traumatic position
- E.g. wisdom tooth biting into cheek
Orthodontic indications
- E.g. remove one of the premolars
Interference with construction of dentures
- Seems wrong as want more natural teeth, but if in detrimental odd anatomical position that would worsen the retention
straight upper anterior forceps
Totally flat unique
- Complete touching table surface
Cannot grab posterior teeth
- stretch cheek
Canine to canine on upper teeth
- Ideally upper central
upper universal forceps
Part of handle lifts of table
- Prevent stretching teeth
- Reach further back
Tip the same
Most single rooted teeth
- Canines, 1st and 2nd molars
- Not as good grip on molar
tips of straight upper anterior and upper universal forceps
have concave surface on either side
- Grab a root
used on Single rooted teeth
why is there a different design for upper molar forceps
3 roots
- 2 palatal and 1 buccal
Need either side
- Tips designed to engage roots regarding orientation
Point
- Designed to go into the furcation between 2 buccal roots
Triangle
- Beak to cheek
Smooth end on one side - concave like first ones
Grab single palatal root
point design of upper molar forceps
- Designed to go into the furcation between 2 buccal roots
Triangle
- Beak to cheek
Smooth end on one side - concave like first ones
Grab single palatal root
lower forceps design feature
90 degree bend for good approach and access
No need for lower right and left
- 2 roots (Mesial and distal)
Furcation on both sides
- Pointy beak engage with furcation on buccal and lingual side
lower universal forceps
90 degree bend for good approach and access
Concave on both sides
- engage root surface
Designed for lower 5 to 5 - one root
lower molar forceps
90 degree bend for good approach and access
Pointy beaks
- Buccal and lingual furcation on lower 6s (mesial and distal root)
‘cowhorn’ forceps
90 degree bend for good approach and access
Very pointy and sharp compared to others
Narrow ended
Highly polished - smooth
Used only 2 rooted lower molars
- Need radiographs
- Divergent/straight/separate roots
Put into furcation gap
Squeeze handle
Points go towards each other and lift the tooth up
- less pressure - good for children as bone softer in young
- less mobilising needed
- if not deep enough can crush crown
how to use ‘cowhorn forceps’
Put into furcation gap
Squeeze handle
Points go towards each other and lift the tooth up
- less pressure - good for children as bone softer in young
- less mobilising needed
- if not deep enough can crush crown
advantages of ‘cowhorn’ forceps
- less pressure - good for children as bone softer in young
- less mobilising needed
disadvantage of ‘cowhorn’ forcep
- if not deep enough can crush crown
3 general principles of extraction
Mobilise teeth with special instrument
Forceps on root
Various movements to expand bone socket to give ease of getting tooth out
bayonet forceps design
Easy to reach back with Z shape
- Bayonet pattern
- Don’t stretch cheek
why need for bayonet forceps
Hard to access upper wisdom teeth
Can use upper molar forceps or the top one
- Root pattern variable
- Don’t know where furcation’s are
- Assume one rooted
- Can be poor grip
upper bayonet third molar forceps
like universal with Z end
Part of handle lifts of table
- Prevent stretching teeth
- Reach further back
tip have concave surface on either side
- Grab a root
upper bayonet root forceps
Fine tip
- Removing little roots
- Fracture
- Not wisdom tooth - too narrow, no grip
where is right handed operator in extractions of lower right molars
standing behind the patient on left to pt
where is left handed operator in extraction of lower left molars
standing behind the patient on right of pt
when does the operator stand in front of the pt in extractions
All upper teeth
- Lower left if right handed
- Lower right if left handed
where does a right handed operator stand when standing in front of the pt
in front of the pt to the right
where does a left handed operator stand when standing in front of the pt
in front of the pt to the left (mind spittoon)
how should you change the pt positions for maxillary extractions
lie pt more flat
what does the correct extraction position allow
Non dominant hand cannot support jaw
- Retract cheek, hard palate, protect pt face
Let light in
purpose of elevators
Forceps good at extracting
- But straight to higher chance of breaking teeth
Minimise breaking teeth and get rid of excess easier use these
- Facilitate the extraction
Loosen tooth
- Roots are mobile - easier to get out
coupland’s elevators
Most popular
Different sizes
- 1 - narrowest
- 2
- 3 - widest (top)
Half universal forceps
- Bit sharper at end
Tear PDL
Elevate the tooth
Individually wrapped
Ends can wear with time
Cryer’s elevators
Sets of 2 in pack (R and L)
Pointy
Curved
Elevate broken fractured retained roots
how to differentiate right and left cryer’s elevators
Concave is pointing towards the ceiling - smile to the sky
Point to each other
One in right and left is left
And engraved usually
Warwick James elevators
Like fine Coupland
Sets of 3
- Distinguish left and right like Cryers
- then straight one
Curved is less pointy
Upper wisdom teeth
- Fit better in narrow space
3 elevators
Coupland’s
Cryer’s
James Warwick
non surgical extractions
Forceps and elevators
No flaps/incisions, no bone removal, no sectioning of teeth
