The aim of the study was to evaluate and assess the clinical stability and efficacy of three-dimensional patient-specific computer-guided titanium plates versus conventional mini plates when used for the treatment of mandibular fractures. Patients with isolated mandibular body fractures were assigned randomly into two equal groups. Group I was treated with patient-specific 3D titanium plates and Group II was treated with conventional mini plates. Outcome measurements included patient satisfaction, pain, occlusion, occlusal bite force and fracture gap distance. All parameters were evaluated at one-week and three-month intervals. The operating time was measured during the surgery. A total of 20 patients were included in the study. Group I (n=10) showed higher values of patient satisfaction and lower pain values than Group II (n=10) at both follow-up intervals. The degree of occlusal derangement showed no statistically significant difference between both groups at one week postoperatively, while both groups showed normal occlusion after 3 months. Occlusal bite forces in Group I were significantly higher than Group II at both follow up intervals. The fracture gap distance was statistically insignificant between both groups at both follow up intervals. The operating time was significantly lower for Group I. Within the limitations of the study, it seems that in the treatment of mandibular body fractures patient-specific plates are preferred over conventional mini plates as they provide more stability, higher biting forces and shorter operating time with highly acceptable outcomes and promising results.
本研究旨在评估和评估三维个体化计算机引导钛板与传统微型板治疗下颌骨骨折的临床稳定性和疗效。将单纯下颌体骨折的患者随机分为两组。I 组采用个体化 3D 钛板治疗,II 组采用传统微型板治疗。疗效评估包括患者满意度、疼痛、咬合、咬合咬合力和骨折间隙距离。所有参数均在 1 周和 3 个月间隔进行评估。手术过程中测量手术时间。共有 20 例患者纳入研究。在两个随访间隔内,I 组(n=10)的患者满意度和疼痛评分均高于 II 组(n=10)。术后 1 周两组的咬合紊乱程度无统计学差异,3 个月后两组均恢复正常咬合。I 组的咬合咬合力在两个随访间隔内均显著高于 II 组。两个随访间隔两组骨折间隙距离均无统计学差异。I 组的手术时间显著缩短。在研究的限制范围内,似乎在治疗下颌体骨折方面,个体化钢板优于传统微型板,因为它们提供了更高的稳定性、更高的咬合力和更短的手术时间,同时具有可接受的结果和有前途的结果。
