Variations of an anterior alveolar process fracture. Dentoalveolar fracture: Any fracture that is limited to the tooth-bearing area of the mandible. (A) Isolated alveolar process fracture: The nondisplaced fracture block is containing the teeth 43, 42, 41, 31, and 32. (B) Fracture combination: A vertical fracture line in the interdental space 44/43 spreads over the full vertical height of the mandible and delineates the vertical margin of an alveolar process fracture. Both fractures are independently documented. (C) Isolated fracture of an edentulous alveolar ridge: Edentulous portion extending from 42 to 32 pretending the missing teeth were still there. (D) Schematic representation of the alveolar process in the mandible by boxes with the FDI tooth numbers. An alveolar process fracture ranging from 43 to 32 is marked in the schematic bar. In the AOCOIAC classification software program7 the involved teeth or tooth sockets, respectively, can be ticked.
