Purpose of the Paper. The study was aimed at identifying the biomechanical properties of the temporomandibular disc. Material. Experimental and model tests were conducted on ten fresh porcine temporomandibular joint discs. The average thickness of disc tissue was, accordingly, 2.77 mm for the anterior zone, 3.98 mm for the posterior, and 1.54 mm for the intermediate. The selection of research material in the form of porcine discs was due to the similarity to human discs. Methods. Discs were loaded in cycles, a temporary course with the amplitude 3 N and frequency 0.07 Hz, and growth in the load was 1 N/s. The selection of load frequency was due to real conditions of temporomandibular joint functioning during mastication. The necessary experimental research was conducted on a testing machine with a measurement range of 2.5 kN. Results. The obtained numeric calculation results indicate that the number of load cycles has a decisive impact on the limitation of energy dispersion capacity through disc tissue. This phenomenon was observed in all the studies on the disc areas. Along with the growth in load cycles, discs are stiffened, and the most significant stiffness was observed in the intermediate area. Conclusions. Based on the conducted research, it should be concluded that excessive load affecting temporomandibular joints caused by the act of mastication and occlusal forces generated during parafunction and in people with defined long-term bruxism has crucial importance on biomechanical disc properties and hence the course of temporomandibular joint conditions.

颞下颌椎间盘生物力学特性的鉴定
本文的目的。该研究旨在鉴定颞下颌椎间盘的生物力学特性。材料。在十个新鲜的猪颞下颌关节盘上进行了实验和模型测试。因此,椎间盘组织的平均厚度为前区为2.77毫米,后区为3.98毫米,中间区为1.54毫米。猪圆盘形式研究材料的选择是由于与人类圆盘的相似性。方法。光盘以循环的方式加载,振幅为3 N,频率为0.07 Hz,是一个临时过程,加载量为1 N / s。负荷频率的选择是由于咀嚼期间颞下颌关节功能的实际情况。在测量范围为2.5 kN的测试机上进行了必要的实验研究。结果。获得的数值计算结果表明,载荷循环次数对通过椎间盘组织的能量分散能力的限制具有决定性的影响。在所有有关椎间盘区域的研究中都观察到了这种现象。随着载荷循环的增加,圆盘变硬,并且在中间区域观察到最大的刚度。结论。根据所进行的研究,应该得出结论,在超功能期间以及确定的长期磨牙症患者中,由咀嚼和咬合力作用引起的影响颞下颌关节的超负荷,对生物力学椎间盘的性质以及颞下颌的病程至关重要联合条件。
