Minor Oral Surgery Techniques Flashcards
why do teeth fracture?
- thick cortical bone
- root shape
- root number
- hypercementosis
- ankylosis
- caries
- alignment
If a tooth fractures, what must you say to the patient?
- explain procedure to patient (going to be surgical)
- tooth may need sectioning… explain
- warn patient of potential damage to adjacent teeth
how might you give a patient an idea of what to expect during a surgical tooth extraction?
- feel pressure but NO pain
- lift the gum up (flap)
- expect drilling & water from drill
- stitches going to be used
what post operative complications may arise from a surgical extraction?
- pain
- swelling
- bruising
- jaw stiffness
- bleeding
- dry socket
- infection
- nerve damage risk
when discussing procedures with patients, what is very important ?
use language that the patient understands
why is soft tissue retraction important during oral surgery?
- allows good access to operative field
- protects the soft tissues
what instrument can be used to retract soft tissues?
- Howarth’s periosteal elevator
- Bowdler-Henry Retractor (rake)
how can physical debridement be undertaken in surgical extractions?
- bone file or handpiece to remove sharp bony edges
- Mitchell’s trimmer or Victoria curette to remove soft tissue debris
how can irrigation debridement be undertaken in surgical extractions?
- sterile saline/water into socket & UNDER FLAP
how can suction debridement be undertaken in surgical extractions?
- aspirate UNDER FLAP to remove debris
- check socket for retained apices etc
why must the Bowdler-Henry Retractor be handled with care?
it has little sharp edges (like a rake) that can damage soft tissues
what are the main aims of suturing after a surgical extraction?
- reposition tissues
- cover bone
- prevent wound breakdown
- achieve haemostasis
- encourage healing by primary intention
what types of sutures are used in oral surgery?
- resorbable
- non-resorbable
what types of resorbable & non-resorbable sutures can be used in oral surgery?
- monofilament
- multifilament
how can haemostasis be achieved during operation of oral surgery extractions?
- LA with vasoconstrictor used
- artery forceps
- diathermy
- bone wax
If a 2 sided root is left in the canal due to the crown fracturing off, and you are struggling to elevate the root out, what can you do?
Separate the roots into 2
- can be separated using a motorised handpiece
Why can you not use a typical high speed/slow speed handpiece to separate roots in oral surgery?
you can cause surgical emphysema which can be fatal
how can haemostasis be achieved post-operatively?
- pressure
- LA with vasoconstrictor
- diathermy
- Whitehead’s Varnish Pack
- surgicel
- sutures
what is found within a Whitehead’s Varnish Pack?
- iodoform
- gum benzoin
- storax
- balsam tolu
- ethyl ether
what does HAPOIG mean?
- haemostasis achieved
- post operative instructions given
what is the most commonly used suture in oral surgery today?
Resorbable multi-filament sutures
what is the most common non-resorbable multifilament suture?
Black silk
what is the hardest suture material to use?
proline (monofilament non-resorbable suture)
- looks like fishing line
Why are multifilament suture materials better than monofilament materials?
You scar less!
If you cross the vermillion border when suturing, what suture material must you use?
Monofilament materials
what is an example of a monofilament resorbable suture material?
MONOCRYL (poliglecarpone 25)
what is an example of a resorbable multifilament suture materials?
VICRYL RAPIDE (polyglactin 910)
what is an example of a non-resorbable monofilament suture materials?
PROLENE (polypropylene)
what is an example of a non-resorbable multifilament suture materials?
Mersilk (black silk)
