The objective of this study was to evaluate the use of one titanium microplate in the fixation of displaced pediatric parasymphysial mandibular fractures.
The study was conducted on 7 children in the mixed dentition stage with displaced parasymphysial fracture. Patients' age ranged between 5 years 9 months and 8 years 4 months with an average of 7 years 1 month. Fractured bone segments were exposed, reduced and then fixed using 1.5 linear microplates at the inferior border of the mandible using monocortical screws, with 1.5 mm in diameter and 5 mm in length. Stainless steel wire was used as a tension band by ligating the teeth around the fracture line. Patients were followed up for occlusion and stability clinically and radiographically (panoramic X-ray and CT).
According to clinical and radiographic post-operative follow-up, none of the patients showed displacement of the fixed bony segments.
The present study concluded that using one microplate with 1.5 monocortical microscrews and dental tension band by a stainless steel wire could be adequate for fixing displaced pediatric parasymphysial mandibular fractures. This technique has the following advantages: decreases the amount of titanium used, decreases the risk of injury of the roots and teeth buds, and decreases the cost and time of surgery.
本研究的目的是评估一块钛微型钢板在固定小儿下颌骨旁正中移位骨折中的应用。
本研究对7例处于混合牙列期的下颌骨旁正中移位骨折患儿进行。患者年龄在5岁9个月至8岁4个月之间，平均年龄为7岁1个月。暴露骨折骨段，复位后使用直径1.5毫米、长度5毫米的单皮质螺钉，在下颌骨下缘用1.5线性微型钢板固定。用不锈钢丝结扎骨折线周围的牙齿作为张力带。对患者进行临床和影像学（全景X线和CT）随访，观察咬合和稳定性情况。
根据术后临床和影像学随访，所有患者固定骨段均未出现移位。
本研究得出结论，使用一块带有1.5单皮质微螺钉的微型钢板并辅以不锈钢丝制成的牙间张力带，足以固定小儿下颌骨旁正中移位骨折。该技术具有以下优点：减少钛的用量，降低牙根和牙胚受伤的风险，降低手术成本和时间。
