Lecture 3

Question 1

What occurs in a simple extraction?

Answer 1

Removal of the tooth without raising a mucosal flap or bone removal.
Teeth still maybe need to be separated prior to extraction

Question 2

What is it very important to do while removing teeth?

Answer 2

Support the rostral and caudal mandible to avoid jaw fractures

Question 3

When do we do surgical extractions?

Answer 3

For canine teeth, maxillary PM4 and mandibular M1.

For this we need horizontal and vertical releasing flaps and the removal of alveolar bone

Question 4

What are the 9 steps for surgical extractions?

Answer 4

1 = Identification of root outline and structure via radiograph
2 = Raising a flap using periosteal elevators
3 = removal of bone >70% for canines and in cats >80% bone removal using a round bur
4 = Tooth division of multi rooted teeth 
5 = Grooves/channels placed on the mesial and distal regions with a tapered fissure bur allows easier access for dental elevators 
6 = Removal of tooth or its fragments
7 = Wound toilet/post op radiograph also thoroughly debride, irrigate and smooth over any rough body edges to assist in wound closure/healing
8 = Primary closure do a releasing periosteal flap incision to allow a tension free closure
9 = Analgesia/antimicrobials
