A hands-on method for instrument-based occlusal analysis with digital technology is presented using a patient case example. The method is based on new software for digital occlusal analysis that includes a new measuring system for recording mandibular function (Jaw Motion Analyser Optic System/oJMA). With the new system, occlusal contact patterns in the real movement function of the mandible are captured and analyzed digitally with regard to occlusal interferences or a suitable therapeutic position of the mandible. For this purpose, scans of both jaws are brought together with the movement recordings by means of a special coupling tray and then visualized together as one complete image. Since the movement paths of the temporomandibular joints (TMJs) are also captured, the new system makes it possible to define a suitable therapeutic position specifically aimed at relieving the TMJs, and a therapeutic change in the jaw relation can be adjusted, for instance, by using an occlusal splint. Dedicated software modules provide a layer-by-layer analysis of the intercuspation relationship and the generation of 'envelopes' for occlusal gliding movements. This system is used to gain a deeper and more comprehensive understanding of the relationship between the structure and function of the occlusion. Interfaces to CAD software have also been established.
本文通过一个病例介绍了一种基于数字技术的仪器性咬合分析的实践方法。该方法基于一种新的数字咬合分析软件,包括一种新的记录下颌功能的测量系统(Jaw Motion Analyser Optic System/oJMA)。使用该新系统,可以捕获下颌真实运动功能中的咬合接触模式,并针对咬合干扰或下颌的合适治疗位置进行数字化分析。为此,通过一个特殊的耦合托盘将上下颌的扫描与运动记录结合在一起,并将其作为一个完整的图像一起可视化。由于也捕获了颞下颌关节(TMJ)的运动轨迹,因此该新系统可以确定一个专门针对缓解 TMJ 的合适治疗位置,并可以调整颌关系的治疗性变化,例如使用咬合垫。专用软件模块提供了对咬合关系的分层分析以及用于咬合滑动运动的“包络”的生成。该系统用于更深入、更全面地了解咬合的结构和功能之间的关系。还建立了与 CAD 软件的接口。
