The purpose of this retrospective study is to evaluate the efficacy of the 2.0-mm locking miniplate/screw system in comparison to the 2.0-mm nonlocking miniplate/screw system in mirror image mandibular fractures.
A retrospective clinical trial was reviewed in the Department of Oral and Maxillofacial Surgery, Government Dental College, Pt. B.D. Sharma University of Health Sciences Rohtak for a period of 30 months (June 2007 to December 2009). A total of 30 patient pairs with isolated identical mandibular fracture (single or multiple) having 88 fractures were analyzed.
A total of 11 complications that occurred represented 12.5% of the total. Six complications occurred at angle, three in the body and two at parasymphysis. Four complications occurred in the locking group and seven in the nonlocking group, with complication rates accounting for 9% and 16%, respectively. When comparing the overall complication rates according to plates used, the chi-square test showed no statistically significant difference between the locking and nonlocking plates (p > 0.05).
Mandible fractures treated with the 2.0-mm locking plates and the 2.0-mm nonlocking plates present similar short-term complication rates.
本回顾性研究的目的是评估2.0毫米锁定微型钢板/螺钉系统与2.0毫米非锁定微型钢板/螺钉系统在下颌骨镜像骨折中的疗效。
在罗塔克市Pt. B.D. 夏尔马健康科学大学政府牙科学院口腔颌面外科进行了一项为期30个月（2007年6月至2009年12月）的回顾性临床试验。共分析了30对患有孤立性相同下颌骨骨折（单发或多发）且共有88处骨折的患者。
共发生11例并发症，占总数的12.5%。6例并发症发生在角部，3例在体部，2例在颏孔旁。锁定组发生4例并发症，非锁定组发生7例，并发症发生率分别为9%和16%。根据所用钢板比较总体并发症发生率时，卡方检验显示锁定钢板和非锁定钢板之间无统计学显著差异（p > 0.05）。
用2.0毫米锁定钢板和2.0毫米非锁定钢板治疗的下颌骨骨折短期并发症发生率相似。
