Abstract

Three-dimensional (3D) mini plate systems are used in the treatment of mandibular fractures. The system is advantageous in comparison to conventional plates due to the stabilization of tension and compression areas, improved initial stability, and biomechanical behavior. The aim of this retrospective study was to evaluate the use of a 3D miniplate system for the treatment of patients with mandibular fractures. Patients with mandibular fractures treated with a 3D plate system at the Department of Oral and Maxillofacial Surgery, University Hospital Münster, during a period of 5 years, were included in this study. Mandibular fracture conditions and minor and major post-operative complications were reported. In total, 336 patients and 391 mandibular fractures were assessed. The most common fracture site was anterior mandible, and 155 cases involved a tooth-bearing area. Minor complications were seen in 8.03% of cases, whereas only 1.49% of patients suffered from major complications. The treatment of mandible fractures using 3D miniplates resulted in fracture reduction with a low complication rate.

Highlights

In the management of mandible fractures, it is essential to restore occlusion, temporomandibular function, and facial esthetics [1,2]
Treatments range from non-surgical management to surgical procedures with osteosynthesis plates, according to the fracture complexity [3]
A successful treatment is influenced by various factors, such as the location and complexity of the fracture, and the plate system and its geometry [4]

Summary

Introduction

In the management of mandible fractures, it is essential to restore occlusion, temporomandibular function, and facial esthetics [1,2]. Treatments range from non-surgical management to surgical procedures with osteosynthesis plates, according to the fracture complexity [3]. In cases where surgical procedure is required, internal rigid fixation techniques promote better stabilization and consolidation of fractured bone. A successful treatment is influenced by various factors, such as the location and complexity of the fracture, and the plate system and its geometry [4]. To ensure successful osteosynthesis with minimal invasive approach, three-dimensional (3D) miniplate systems can be used [7,8,9,10,11]. When placed in the fracture line, the 3D miniplate system ensures fracture stabilization, regardless of plate thickness and geometry [10]. The placement of screws in a square pattern on either side of the fracture creates a solid platform that increases resistance to twisting and rotation of the longitudinal axis of the plate [10]
