Mandibular fractures are among the most common facial injuries. This case report demonstrates the efficacy of simultaneous usage of miniscrews and direct bonding techniques without open reduction in an extensive traumatized patient. A 25-year-old girl with multiple injuries in the head and facial region 1 month after a plane crash accident was referred to manage the mandibular fractures. Due to the presence of multiple injuries, a conservative treatment of symphysiseal fracture was performed. In order to keep the fractured fragments of the mandible close together, the anterior teeth of the lower arch were tied by means of the orthodontic wire. Ten miniscrews were used to improve the anchorage units and also, settling the occlusion by means of light intermaxillary elastics. Following the active treatment, clinical and radiographic analysis showed satisfactory healing without any periodontal involvement of the teeth in the fracture line.
下颌骨骨折是最常见的面部损伤之一。本病例报告展示了在一名广泛创伤患者中,同时使用微型螺钉和直接粘接技术而不进行切开复位的疗效。一名25岁女孩在飞机坠毁事故1个月后,头部和面部多处受伤,前来治疗下颌骨骨折。由于存在多处损伤,对正中联合骨折进行了保守治疗。为了使下颌骨骨折碎片紧密贴合,用正畸钢丝绑扎下牙弓的前牙。使用10枚微型螺钉改善锚固单元,并通过轻力颌间弹力牵引调整咬合。积极治疗后,临床和影像学分析显示愈合良好,骨折线处牙齿无任何牙周受累情况。
