This study was performed to evaluate the efficacy and post-operative complication of 3-dimensional (3D) titanium miniplate and locking plate in mandibular fractures (parasymphysis, symphysis, body, and angle).
Forty patients, with non-comminuted mandibular fractures treated with open reduction and internal fixation using 3D titanium miniplate system or locking plate system through an intra-oral approach, were included in this study. All patients were systematically monitored up to 2 months post-operatively. Parameters recorded were infection, occlusal discrepancies, hardware failure, wound dehiscence, sensory disturbance of the inferior alveolar nerve, and stability of fractured segments.
Forty patients with mandibular fracture were divided into two groups randomly without any bias. The fractures of all 40 patients were found to be adequately fixed when checked intra-operatively after fixation. One patient (2.5%) of the 3D plate group developed an infection on the first and second post-operative visit and was treated by antibiotic coverage. One patient in the locking plate group (2.5%) reported wound dehiscence after the first week follow-up.
Both 3D titanium miniplates and locking plate are effective in the treatment of mandibular fractures, and overall complication rates are lesser. However, the 3D plating system uses less hardware in cases of parasymphysis and symphysis fractures and more hardware in cases of body and angle fractures.
本研究旨在评估三维（3D）钛微型钢板和锁定钢板在下颌骨骨折（颏旁、颏部、体部和角部）治疗中的疗效及术后并发症。
本研究纳入40例采用口内入路，使用3D钛微型钢板系统或锁定钢板系统进行切开复位内固定治疗的非粉碎性下颌骨骨折患者。对所有患者进行术后2个月的系统监测。记录的参数包括感染、咬合差异、内固定失败、伤口裂开、下牙槽神经感觉障碍以及骨折段的稳定性。
40例下颌骨骨折患者被随机无偏倚地分为两组。固定后术中检查发现所有40例患者的骨折均得到充分固定。3D钢板组有1例患者（2.5%）在术后第一次和第二次随访时发生感染，经抗生素治疗。锁定钢板组有1例患者（2.5%）在术后第一周随访时报告伤口裂开。
3D钛微型钢板和锁定钢板在治疗下颌骨骨折方面均有效，总体并发症发生率较低。然而，3D钢板系统在颏旁和颏部骨折病例中使用的内固定物较少，而在体部和角部骨折病例中使用的内固定物较多。
