ABSTRACT:
Objective: The presence of an impacted third molar (3M) increased the risk of mandibular angle fractures (MAFs).
Purpose: To investigate the differences in the fixation patterns in MAFs, in terms of number and thickness of plates, between patients in whom a third molar was maintained or removed.
Materials and methods: A retrospective study including 749 patients ≥16 years of age, with 774 MAFs from six European maxillofacial trauma centers from 2008 to 2018 (Coordinating Center: Division of Maxillofacial Surgery, University of Turin, Italy). The patients treated

by open reduction and internal fixation (ORIF), they had an erupted or impacted 3M in the fracture line and had a follow-up duration of 6 months. The study population was divided into patients in whom the 3M was maintained (group 1: 548 patients) and those in whom the 3M was extracted (group 2:201 patients), and the two groups were compared for differences in the ORIF pattern.
Results: The majority of patients was males (89,9%), ranged in age from 16 to 85 years (mean: 30.7). The main cause of MAFs was assault (54.1%). The most frequent fracture pattern was single angle fracture (42.6%) and the main surgical approach was intraoral (67%). A total of 1,050 plates were placed: 849 were ≤1.4 mm (80,9%) and 201 ≤1.5 mm thick (19,1%). Statistically significant differences were seen in the number of ≤1.4 mm plates between the two groups for single undisplaced/displaced MAF and for undisplaced/displaced angle + parasymphysis/body fractures (P-value≤0,5).
Conclusion: The optimal surgical management of MAFs remains a matter of debate. Although the recent trend is toward a functional nonrigid fixation with a single miniplate on the external oblique ridge, the majority of surgeons of our sample perform a rigid fixation in the angular region when removing the 3M.
