(36 cards)
Aims
Surgical tooth extraction involves
Altering tooth’s path of removal to aid tooth extraction
What are the ways a tooth’s path of removal can be altered to aid tooth extraction in Surgical tooth extraction
1) bone removal
2) tooth sectioning
3) raising flaps
Minimally invasive surgery
What does it include?
Advantages of minimally invasive surgery?
Disadvantages of minimally invasive surgery?
Flap design
What flaps do we raise?
What do those flaps include
Full thickness mucoperiosteal flap (FTMP)
Which include:
– Surface mucosa
– Submucosa
– Periosteum
Why raise a flap
Flap design considerations
(What do we consider when making a flap?)
Size of a flap?
what may happen if flap is too small?
Anatomical considerations of a flap?
What are the different types of flap designs?
- Envelope flap
- 2 sided flap
- 3 sided flap
Envelope flap - where is it placed?
2 sided flap
Used when?
Used for removal of which teeth?
3 sided flap - where is it placed?
Key principles for Making flaps
Equipment for a flap
Once flaps have been made, what happens?
How Is it done?
Reflection
1
what happens after reflection?
2
purpose of this step?
3
what instrument may we use for this step?
4
where should the instrument sit?
- flap retraction
1
what would we usu do after we have access to the surgical site
2
why do we remove bone?
3
how much bone do we remove/ method (image)
1
usu remove bone
2
to access root surface of tooth
3
- need balance of taking tooth out in efficient manner but also not causing too much trauma to the patient
Bone removal method part 2
1
Tooth sectioning techniques
2
What are the main Burs used?
How do we section lower molars or upper 1st premolar
Circumferential bone removal around roots
How to section upper molars?
Method of removing teeth
