Unilateral fractures of the interdental space and horizontal ramus


Fractures of the mandibular interdental space and horizontal ramus can be unilateral, and the fragments are either slightly displaced or severely displaced and highly mobile.

These fractures are very common and their location and type vary greatly. Typically, the fracture line runs from craniodorsal to caudoventral. The fracture starts dorsally either close to the incisors or close to the cheek teeth and runs caudally and ventrally. It is very rare, that the fracture runs from rostroventral to caudodorsal.




Fractures of the interdental space and horizontal ramus: Clinical signs

Clinical signs can be moderate or severe pain and typically the skull has an asymmetric appearance.
