Answer:
Most angle fractures are managed by open reduction and internal fixation because of the tendency for displacement of the proximal segment. An incision is made in the buccal vestibule and the fracture site is exposed. After reduction, a plate is applied, often requiring a transcutaneous trochar for screw placement.
When an erupted third molar is present in the distal segment, it may have to be removed to create space for a drill hole in the distal fragment and because the tooth is in the way of the fixation. When the third molar is completely erupted and retained in the proximal segment, it will usually occlude with its counterpart in the maxillary arch and prevent rotation of the proximal segment. In this case, it should be preserved and used to advantage in reducing the fracture by closed methods.
