(1) : Mandibular fractures are common, with the condylar process being a frequent site of injury, accounting for 25-45% of cases. This research aims to assess the mechanical suitability of various plates for high-neck condyle fractures. (2) : Polyurethane models mimicking high-neck condyle fractures were utilized in this study. Sixteen distinct plate designs, constructed from titanium sheets, were tested. The figures underwent force assessments on a durability testing apparatus, and the relationship between used force and fracture movement was documented. (3) : For high-neck breaking, the two straight plates emerged as the most effective, aligning with established osteosynthesis standards. The second-best plate exhibited nearly half the strength of the gold standard. (4) : In response to the aim of this study, considering the mechanical aspects, the double plain plate stands out as the optimal choice for osteosynthesis in cases of high-neck fractures of the mandibular condylar process. In addition, the authors propose the Mechanical Excellence Factor (MEF) as a superior metric for appraising a plate's mechanical force, surpassing the conventional Plate Design Factor (PDF).
(1):下颌骨骨折很常见,髁突是常见的损伤部位,占病例的25 - 45%。本研究旨在评估各种钢板用于高位髁突骨折的力学适用性。(2):本研究使用了模拟高位髁突骨折的聚氨酯模型。测试了由钛板制成的16种不同的钢板设计。这些模型在耐久性测试装置上进行了力评估,并记录了所用力量与骨折移动之间的关系。(3):对于高位骨折,两种直板表现最为有效,符合既定的骨接合标准。第二有效的钢板强度几乎是金标准的一半。(4):针对本研究的目的,从力学方面考虑,双平板在髁突高位骨折的骨接合中是最佳选择。此外,作者提出力学卓越因子(MEF)作为评估钢板力学力的优越指标,优于传统的钢板设计因子(PDF)。
