Mandibular movement analysis is a critical step in making the functional occlusal morphology and improving the diagnosis and treatment of temporomandibular joint disorders (TMDs). Cadiax Compact® is an electronic condylograph that claims to record the horizontal condylar inclination (HCI), Bennett angle (BA) and relative shape of the articular eminence. This study aims at assessing the accuracy of Cadiax Compact® II in its claimed abilities.
The electronic condylograph (Cadiax Compact®II) was fitted on the fully adjustable articulator (gamma dental reference-SL). After setting of HCI and BA on the arbitrary degrees, eccentric movements were produced manually on the articulator. The Cadiax recorded these preadjusted angles and the accuracy of its recordings was assessed by comparison of the results with the preadjusted HCI, BA and color inserts as references.
The majority of the comparisons showed statistically significant differences between articulator settings and Cadiax recordings. However, the maximum difference was about 2.50 which seems acceptable for clinical practice.
The obtained results showed that Cadiax Compact is an accurate and reliable instrument for diagnostic purposes, yielding reproducible measurements. Despite this, Cadiax is a technically sensitive device that can preclude its routine usage.
下颌运动分析是确定功能性咬合形态以及改善颞下颌关节紊乱病(TMD)诊断与治疗的关键步骤。Cadiax Compact®是一种电子髁突描记仪,宣称可记录髁突水平倾斜度(HCI)、Bennett角(BA)以及关节结节的相对形态。本研究旨在评估Cadiax Compact® II在其宣称功能方面的准确性。
将电子髁突描记仪(Cadiax Compact®II)安装在全可调式牙合架(gamma dental reference - SL)上。在任意度数设定HCI和BA后,在牙合架上手动进行非正中运动。Cadiax记录这些预先调整好的角度,并通过将结果与预先调整的HCI、BA以及彩色插入物作为参考进行比较,来评估其记录的准确性。
大多数比较显示牙合架设置与Cadiax记录之间存在统计学显著差异。然而,最大差异约为2.50,这在临床实践中似乎是可以接受的。
所得结果表明,Cadiax Compact是一种用于诊断目的的准确可靠仪器,能产生可重复的测量结果。尽管如此,Cadiax是一种技术上敏感的设备,这可能会妨碍其常规使用。
