The treatment of fractures prioritizes the restoration of functionality through the realignment of fractured segments. Conventional methods, such as titanium plates, have been employed for this purpose; however, certain limitations have been observed, leading to the development of patient-specific plates. Furthermore, recent advancements in digital technology in dentistry enable the creation of virtual models and simulations of surgical procedures. The aim was to assess the clinical effectiveness of patient-specific plates utilizing digital technology in treating mandibular fractures compared to conventional titanium plates.
Twenty patients diagnosed with mandibular fractures were included and randomly assigned to either the study or control groups. The surgical procedure comprised reduction and internal fixation utilizing patient-specific plates generated through virtual surgery planning with digital models for the study group, while the control group underwent the same procedure with conventional titanium plates. Assessment criteria included the presence of malunion, infection, sensory disturbance, subjective occlusal disturbance and occlusal force in functional maximum intercuspation (MICP). Statistical analysis involved using the Chi-square test and one-way repeated measures analysis of variance.
All parameters showed no statistically significant differences between the study and control groups, except for the enhancement in occlusal force in functional MICP, where a statistically significant difference was observed (p = 0.000).
Using patient-specific plates using digital technology has demonstrated clinical effectiveness in treating mandibular fractures, offering advantages of time efficiency and benefits for less experienced surgeons.
Patient-specific plates combined with digital technology can be clinically effective in mandibular fracture treatment.
骨折的治疗重在通过重新排列骨折段来恢复功能。为此，传统方法如钛板已被广泛应用，但观察到某些局限性，从而导致了个体化定制钢板的发展。此外，牙科领域数字化技术的最新进展使得虚拟模型的创建和手术模拟成为可能。本研究旨在评估数字化技术辅助的个体化定制钢板在治疗下颌骨骨折方面相较于传统钛板的临床疗效。
共纳入 20 名下颌骨骨折患者，随机分为研究组和对照组。手术步骤包括使用数字化模型进行虚拟手术规划，为研究组生成个体化定制钢板，然后进行复位和内固定；对照组则采用传统钛板进行相同的手术。评估标准包括骨愈合不良、感染、感觉障碍、主观咬合干扰和功能最大牙尖交错位（MICP）的咬合力。统计分析采用卡方检验和单向重复测量方差分析。
除了功能 MICP 中的咬合力显著增强（p=0.000）外，研究组和对照组的所有参数均无统计学差异。
数字化技术辅助的个体化定制钢板在治疗下颌骨骨折方面具有临床疗效，具有提高手术效率和对经验较少的外科医生有益的优势。
个体化定制钢板联合数字化技术可在治疗下颌骨骨折中发挥临床疗效。
