[Surgical treatment of lower jaw pseudoarthrosis as a result of fracture non-treatment following tooth extraction].

Fracture of the lower jaw following tooth extraction is a rare and severe complication, occurring most often in the preangular region following third molar extraction. When left untreated, pseudoarthrosis can occur. Symptoms show a wide variance, including pathologic mobility, pain and infection, as well as sometimes trismus before and following surgical treatment.
