Computerized axiography was used as an objective instrumental method of evaluating the response of patients with temporomandibular joint (TMJ) symptomatology to occlusal splint therapy. Diagnosis was performed in a standardized manner by systematically analyzing TMJ path tracings obtained by computerized axiography. Thirty-six patients were axiographed before and after therapy with full-arch occlusal stabilizing appliances, followed by assessing the effect of therapy on various path curve parameters. The data obtained for the patient group treated with splints was compared to that of six patients also axiographed, but left untreated for a period of six weeks before a second TMJ tracing was obtained. The results show that splints have a certain effect on reciprocal TMJ clicking (response rate 67%). Retral stability and path characteristics are also substantially improved (response rates 44% and 40%). Less influence was noted on hypomobile joint paths (response rate 29%), the quality of movements (response rate 28%) and Bennett angle values (response rate 23%). Patients with disk displacements without reduction were not treated with splints, they underwent surgery. Their results will be reported later. By contrast, TMJ tracings in the control group remained essentially unchanged.
计算机轴描记法被用作一种客观的仪器方法，用于评估颞下颌关节（TMJ）有症状的患者对咬合板治疗的反应。通过系统分析计算机轴描记法获得的TMJ轨迹，以标准化方式进行诊断。36例患者在使用全牙弓咬合稳定矫治器治疗前后进行了轴描记，随后评估治疗对各种轨迹曲线参数的影响。将使用咬合板治疗的患者组获得的数据与另外6例也进行了轴描记的患者的数据进行比较，但这6例患者在获得第二次TMJ轨迹前六周未接受治疗。结果表明，咬合板对TMJ交互弹响有一定效果（有效率67%）。后退稳定性和轨迹特征也有显著改善（有效率分别为44%和40%）。对关节活动度降低的轨迹（有效率29%）、运动质量（有效率28%）和Bennett角值（有效率23%）的影响较小。不可复性盘移位患者未接受咬合板治疗，而是接受了手术。他们的结果将在以后报告。相比之下，对照组的TMJ轨迹基本保持不变。
