TRUE OR FALSE:

Implants for repair of mandibular/maxillary fractures  can be absorbable and non-absorbable?

TRUE

absorbable are great for pediatric cases but limited

non-absorbable are most commonly used in adult fractures

Does a repair always require plates and screws?

Most require both, but 2 screws without a plate can be used instead.  It is dependent upon the fracture and the surgeon's discretion.
