摘要/Abstract

摘要： 目的:本研究通过探讨数字化技术结合3D打印手术导板在复杂下颌骨骨折中的临床应用价值,以期为后续骨折患者治疗的精准化、个性化、微创化提供临床依据。方法:收集2023年1月~2024年6月期间河北医科大学第三医院口腔颌面外科收治的20例复杂下颌骨骨折患者病例资料,所有患者术前均使用数字化软件进行三维可视化模型建模,应用Mimics/3-matic软件进行虚拟手术复位,设计并打印3D手术导板,术中应用导板辅助下颌骨骨折的精确复位及钛板固定。术后使用数字化软件行色彩偏差分析和临床效果评价。结果:术后色彩偏差分析结果显示,平均偏差(0.92±0.28) mm,骨段最大偏差(1.98±0.35) mm。该结果表明患者下颌骨骨折复位重建位置与虚拟手术设计具有较高的一致性。临床效果评估结果显示,优良率达到100%(优90.0%,良10.0%),无明显并发症患者功能与面部形态均得到满意恢复。结论:数字化技术与3D导板应用于复杂下颌骨骨折的诊疗时,能优化手术路径,极大提升了骨折复位的精确度,降低术后并发症的发生率,具有较高的临床应用价值。

Abstract: Objective: To explores the clinical application value of digital technology combined with 3D printed surgical guides in complex mandibular fractures. Methods: The data of 20 patients with complex mandibular fractures admitted to the Department of Oral and Maxillofacial Surgery of the Third Hospital of Hebei Medical University from January 2023 to June 2024 were collected. For all patients, three-dimensional visualization models were established using digital software before the operation. Virtual surgical reduction was performed using Mimics/3-matic software, and 3D surgical guides were designed and printed. During the operation, guide plates were used to assist in the precise reduction of mandibular fractures and the fixation of titanium plates. After the operation, digital software was used for color deviation analysis and clinical effect evaluation. Results: Postoperative color deviation analysis showed that the average deviation was (0.92±0.28) mm and the maximum deviation of the bone segment was (1.98±0.35) mm. The patient's mandibular fracture reduction and reconstruction position had a high consistency with the virtual surgical design. Clinical effect evaluation showed that the excellent and good rate reached 100% (excellent 90.0%, good 10.0%), and the patient's functions and facial morphology were satisfactorily restored without obvious complications. Conclusion: Digital technology and 3D guides can optimize the surgical path, improve the accuracy of fracture reduction, and reduce the chance of postoperative complications in the diagnosis and treatment of complex mandibular fractures.
