After completing this exhibit, viewers will be able to…  List the most common patterns of bilateral mandibular fractures in blunt trauma  Explain the importance of basal triangles and alveolar fracture components in determining appropriate management.  Describe findings that warrant tooth extraction in dentolaveolar trauma. 

  1. Anatomy and biomechanics Mechanisms of injury Goals of treatment: occlusional and osseous reduction Different surgical approaches for different segment fractures Biomechanics- lines of tension and compression   2. Common fracture patterns Simple single fractures Multiple unilateral fractures Multiple bilateral fractures Basal triangles Alveolar fracture segments Comminuted fractures  3. Teeth in the line of fracture Closed vs open/contaminated Open/contaminated: Antiobiotics vs extraction Indications/contraindications for extraction  4. Atypical/uncommon fracture patterns Isolated coronoid fractures Special considerations in edentulous atrophic fractures 5. Complications Nerve injuries Aspirated teeth Risk factors for osteomyelitis Risk factors for malunion/non-union TMJ Ankylosis
