Bone Removal and Sectioning Teeth Flashcards
What are the indications for bone removal and tooth sectioning
- Gain access to a buried object e.g. tooth, root, pathology etc
- Achieve a deeper application point
- Section crown of impacted tooth
- Section of a multi-rooted tooth
What side of the tooth is bone removal performed on
On the buccal aspect of the tooth/root
What is the rpm range for a surgical drill
35-40k
What 2 types of bur are available for surgical drills
- Rose head bur
- A tapered fissure bur
What are the benefits of using a rose head bur for surgical removal of alveolar bone
- More easily cooled and washed by a saline jet
- The site at which they’re cutting is more easily seen
What are the benefits of using a tapered tissue bur for surgical removal of bone
- Gives a narrower gutter and greater depth, which when used appropriately can be time saving and bone saving
Where is the gutter of bone made
On the buccal aspect of the tooth to visualise the root or furcation point
What is the best bur for sectioning teeth
A tapered fissure bur
How far should you cut into the tooth when sectioning it and why
All the way except for the lingual aspect to avoid trauma to the lingual tissues and potentially the lingual nerve
Why does the bur cut create a space between roots
As this permits curved or divergent roots to move away from one another as they are elevated
What is used to split the crown after a partial division is made with the surgical bur
An elevator
