Clinical study on the proginosis of the teeth in the mandibular fracture line

This article is a retrospective study on the 188 patients with 327 fracture lines and 502 teeth in the tooth-bearing mandibular fracture. The patients were treated at the Department of Oral and Maxillofacial Surgery in Wonkwang University Hospital from August, 1984 to Sepetmber, 1988. The total number of removed teeth in the mandibular fracture line were 104 (20.5%) and that of the retained teeth were 398(79.5%). The complications of the tooth-retained-group were 24.6% and those of the tooth-removed-group were 24.4%. Owing to the comparison of the complications of the fracture group in which the teeth were removed with the other fracture group in which the teeth were retained, it is suggested that removal of the teeth in the fracture line could not minimize the complications. The most common complication of the tooth-retained-group was acute infection (58.6%) and that of the tooth-removed-group was malocclusion(41.2%). It is concluded that the teeth in the mandibular fracture line can be preserved with the proper antibiotic therapy, except the case of the hopelessly traumatized teeth or severely complicated case.
