BACKGROUND
In the present study, 20 patients with mandibular fracture were included to evaluate the versatility of titanium 3D plate in comparison with conventional titanium miniplate fixation.
METHODS
The patients were alternatively allocated to either the 3D plate group or Miniplate group. The patients were evaluated for the clinical assessment of mobility after fixation, pre and post-surgical occlusal relationship, adequacy of reduction on post operative radiograph and any post surgical complications.
RESULTS
All 25 fractures in 20 patients were found to be adequately fixed when checked intra-operatively. No post-operative IMF was required in either of the groups. The mean radiographic score at post operative time interval in Miniplate group was found to be 2.80 ± 0.42 and in 3D Plate was found to be 2.90 ± 0.32. The mean radiographic score at 3 months time interval in Miniplate group was found to be 2.70 ± 0.48 and in 3D Plate was found to be 2.70 ± 0.48. Radiolucency at 3 months period was found in 1 patient (10%) in the miniplate group and it was not found in any patients in the 3D plate group. None of the patients in both the groups had complications of non-union or mal-union. In miniplate group, 2 patients (20%) had infections and in 3D plate group 1 patient (10%) had infection. 3 patients in miniplate group had occlusal discrepancies (30%) and 1 patient in 3D plate group had occlusal discrepancies (10%). Overall, complications were found in 6 patients (60%) in miniplate group and 2 patients (20%) in 3D plate group. The data when compared was statistically significant (P < 0.05).
CONCLUSION
The 3D plating system was found to be advantageous over conventional miniplates. It uses lesser foreign material, reduces the operation time and overall cost of the treatment. Thus 3D plate can be used as an alternative to conventional miniplates. The system is reliable and effective treatment modality for mandibular fractures.
背景
在本研究中，纳入了20例下颌骨骨折患者，以评估钛3D接骨板与传统钛微型接骨板固定相比的多功能性。
方法
将患者交替分配至3D接骨板组或微型接骨板组。对患者进行固定后活动度的临床评估、手术前后的咬合关系、术后X线片上复位的充分性以及任何术后并发症的评估。
结果
术中检查发现，20例患者的25处骨折均得到充分固定。两组均无需术后颌间固定。微型接骨板组术后时间间隔的平均影像学评分为2.80±0.42，3D接骨板组为2.90±0.32。微型接骨板组3个月时间间隔的平均影像学评分为2.70±0.48，3D接骨板组为2.70±0.48。微型接骨板组1例患者（10%）在3个月时出现透光影，3D接骨板组未发现任何患者出现透光影。两组患者均无骨不连或畸形愈合并发症。微型接骨板组2例患者（20%）发生感染，3D接骨板组1例患者（10%）发生感染。微型接骨板组3例患者（30%）存在咬合差异，3D接骨板组1例患者（10%）存在咬合差异。总体而言，微型接骨板组6例患者（60%）出现并发症，3D接骨板组2例患者（20%）出现并发症。比较数据时具有统计学意义（P<0.05）。
结论
发现3D接骨板系统优于传统微型接骨板。它使用的异物较少，减少了手术时间和治疗总成本。因此，3D接骨板可作为传统微型接骨板的替代品。该系统是治疗下颌骨骨折可靠且有效的治疗方式。
