What must you place on a mandibular labial avulsion prior to suture reconstruction and what does it do?

What can inadequate management of mandibular and maxillary fractures lead to?
Malalignment, malocclusion, or non-healing fractures

Even distribution
Where in the mandible are fractions most common in a cat?

How do you treat a closed hard palate fracture?
None indicated as long as malocclusion is ok
When do interfragmentary wires work best?
When combined w/interdental wire
Primary complications are premature loosening and soft tissue irritation
