Abstract

Purpose: The aim of this study was to analyze the demographic variables and causes and characteristics of mandibular angle fractures managed at several European departments of maxillofacial surgery.

Materials and methods: This study was based on a multicenter systematic database that allowed the recording of data from all patients with mandibular angle fractures between January 1, 2013, and December 31, 2017. The following data were recorded: gender, age, etiology, side of angle fracture, associated mandibular fractures, presence of third molar, intermaxillary fixation, and osteosynthesis.

Results: The study included 1,162 patients (1,045 male and 117 female patients). A significant association was found between the presence of a third molar and the diagnosis of an isolated angle fracture (P < .0000005). Furthermore, assaults were associated with the presence of voluptuary habits (P < .00005), a younger mean age (P < .00000005), male gender (P < .00000005), and left-sided angle fractures (P < .00000005).

Conclusions: Assaults and falls actually represent the most frequent causes of angle fractures. The presence of a third molar may let the force completely disperse during the determination of the angle fracture, finding a point of weakness.
