Because of its prominence in the facial structure, the mandible is highly prone to fracture. A clinical study on 122 patients with mandibular fracture who visited Kangnam General Hospital during 4 years(1992-1995) was done by analysing sex, age, cause, fracture site, teeth involvement, treatment method, complication and involement of other body part.
