To compare the angle of the sagittal condylar guidance obtained from the radiographic and clinical records of dentate patients.
The sample consisted of 32 patients in whom strict lateral radiography and positional records were performed: in centric relation, protrusive recording 5 mm in right laterality and protrusive recording 5 mm in left laterality. With the positional registration of the facebow, the upper model was articulated, while the lower model was articulated with the positional registration in centric relation, and with the protrusive lateral registrations on the right and left side the condylar guidance was obtained for programming the semi-adjustable articulator. Statistics were performed with the SPSS program version 24 in Spanish. Normality was evaluated using the Shapiro-Wilk test, for data with normal distribution, and the Student's T test and Pearson's correlation were performed in descriptive statistics.
The statistical analyses showed that gender and age influence the angle measurement of the sagittal condylar guide. The radiographic method presented a condylar guide angle of 35.69 ± 5.18, being 35.69 ± 5.16 with the clinical method (p> 0.05). Pearson's correlation test showed an important correlation between the two methods (r = 0.948, p <0.001).
There is a high correlation in the measurements obtained from the angle of the sagittal condylar guide and the radiographic and clinical records, indicating that both methods are effective.
比较从有牙患者的影像学和临床记录中获得的髁突矢状向引导角。
样本包括32例患者,对其进行了严格的侧位X线摄影和位置记录:正中关系位、右侧侧方突出5mm记录位以及左侧侧方突出5mm记录位。通过面弓的位置记录,对上颌模型进行咬合架定位,而下颌模型则在正中关系位的位置记录以及左右侧突出侧方记录的基础上进行咬合架定位,从而获得髁突引导,用于对半可调式咬合架进行编程。使用西班牙语版的SPSS 24程序进行统计分析。使用Shapiro-Wilk检验评估数据的正态性,对于呈正态分布的数据,在描述性统计中进行学生t检验和Pearson相关性分析。
统计分析表明,性别和年龄会影响髁突矢状向引导角的测量。影像学方法测得的髁突引导角为35.69±5.18,临床方法测得的为35.69±5.16(p>0.05)。Pearson相关性检验显示两种方法之间存在显著相关性(r = 0.948,p <0.001)。
从髁突矢状向引导角的测量以及影像学和临床记录中获得的结果具有高度相关性,表明这两种方法均有效。
