摘要

: To compare the aspect of the reproduction accuracy in studied methods of determination of the (CR) of jaws using the digital research methods. The methods used were bilateral manipulation by P.E. Dawson, frontal deprogrammer, leaf gauge, and intraoral device for recording of Gothic arch angle. : To determine the reproduction accuracy of the centric relation of jaws, we examined 5 patients with intact dentition in a prosthetic dentistry clinic (first class in Angle’s system). For each method, 20 registrations of the centric jaw relation were carried out by one operator. The breaks between definitions were 30 minutes. A total of 400 CR recording operations were carried out (400 records of CR). In order to study the reproducibility of CR determination methods, 200 recorded mandible positions were analyzed by means of an analog-to-digital method (a macro kit Canon 650D, Canon 60 mm macro IS USM f2.8, Canon macro ring MR-14 EX and the computer program Adobe Photoshop) to assess the first occlusal contact obtained in the CR of jaws, while the other 200 were analyzed by means of a digital method (the computer program Avantis for 3D modeling, Prime as a laboratory 3D scanner (DOF), and Trios as an intraoral scanner (3Shape)) to assess the spatial position of the mandible in the CR. Statistical analysis was carried out using STATISTICA-10. In all statistical analysis procedures, the critical significance level p was assumed to be 0.05. : In the study of the data by means of the computer program Avanti 3D, the reproducibility of the mandible position in the CR reached 0.119 ± 0.012 mm for frontal deprogrammer, 0.225 ± 0.028, ≤ 0.05 for bilateral manipulation by Dawson P.E., 0.207 ± 0.02, ≤ 0.05 for leaf gauge, and 0.120 ± 0,013, ≤ 0.05 using an intraoral device for recording the Gothic arch angle. The analog-to-digital method showed an identical tendency for reproduction of the mandible position. : The digital analysis we made using the Avantis 3D program showed, with high confidence, that the maximum reproducibility of the CR position was reached by using our own design frontal deprogrammer and the device for recording Gothic arch angle.

Dawson，额叶去编程器，叶规和用于记录哥特式弓角的口腔内装置。为了确定颌骨中心关系的复制准确性，我们在义齿牙科诊所（Angel系统中的第一等）检查了5名牙齿完整的患者。对于每种方法，由一名操作员执行20次中心颌关系的配准。定义之间的间隔为30分钟。总共进行了400次CR记录操作（400次CR记录）。为了研究CR测定方法的可重复性，通过模数方法（佳能650D宏套件，佳能60 mm宏IS USM f2.8，佳能宏环MR-14）分析了200个记录的下颌骨位置EX和计算机程序Adobe Photoshop）评估在颌部CR中获得的第一个咬合接触，而其他200个通过数字方法进行分析（计算机程序Avantis用于3D建模，Prime作为实验室3D扫描仪（DOF ）和Trios作为口内扫描仪（3Shape）来评估下颌骨在CR中的空间位置。使用STATISTICA-10进行统计分析。在所有统计分析程序中，关键显着性水平p均假定为0.05。 ：在通过计算机程序Avanti 3D进行的数据研究中，额叶编程器中CR下颌位置的可再现性达到0.119±0.012 mm，Dawson PE进行双边操作时≤0.225±0.028，≤0.05，0.207±0.02 ，对于叶规，≤0.05，使用口腔内装置记录哥特式弓角的≤0.120±0,013，≤0.05。模数法显示下颌位置的再现趋势相同。 ：我们使用Avantis 3D程序进行的数字分析表明，通过使用我们自己设计的正面前置编程器和记录哥特式足弓角度的装置，可以高度放心地获得CR位置的最大可重复性。
