What are the steps to removing a buried tooth?

1. Draw a line through the long axis of the tooth passing through the centre to locate where the tooth is located

2. Draw a horizontal line beneath the root apex of the teeth (horizontal upper limit). Do not cut above this line to avoid damaging the roots. The point where the line from step 1 and step 2 cross should be the top centre of the bone cut out you peform

*Note from here using postage stamp technique

3. Drill multiple holes with the round bur in the outline of the section of bone to be removed. Ensure you drill down to the marrow (feel a drop) and that you do not pass your outline through any nerves. Retract tissues and protect important structures like nerves with the metal retractor

4. Join the holes up with a flat fissure bure

5. Using a James Warwick elevator, gently pry off the section of bone you have outlined

6. Remove both the soft and hard tissue of the unerupted tooth using the warwick james elevator

7. Suture the wound up.
