Bone removal

Front 22

What is a coronectomy and what are some reasons you might do it?

Back 22

Coronal portion of tooth removed only
1. if traumatic risk is high
2. Pericoronitis
3. Intimate relationship w/mandibular canal (passive eruption will follow)

Front 23

What is an Osteotome (wedge)?

Back 23

Used to section tooth (but not a chisle)

Front 24

**Why should you always put a retracter on D of Max 3rd?

Back 24

So you don't elevate it into the infratemporal space.

Front 25

What are the characteristics of the Ideal Alveolar Ridge?

Back 25

1. Proper jaw relationship and intermaxillary space
2. U-shaped ridge
3. No bony or soft tissue protuberances or undercuts
4. Adequate attached keratinized mucosa in primary denture bearing area
5. Adequate vestibular depth
6. Adequate bone height and width
