| 内容記述 | This article reviews problems in locating the analysis point of condylar movements and suggests the clinical application of the rotation center of the condylar movement during protrusion as a posterior reference point for the articulator. There are mainly three problems in measuring and expressing three-dimensional condylar movements. The first problem is that the condylar movement is hidden under the skin and thus not directly visible. Previously roentgenographic methods, called cinefluorography, were used to study condylar movement, but ethics committee no longer allow the use of X-ray imaging methods for such experimental purposes because of the radiation damage. The recent development of ultra high speed MR imaging method is expected to contribute to the non-invasive study on condylar movement. The second problem is that it is difficult to describe condylar movement because it is the movement of a three-dimensional object. This raises question of what descriptions are suitable for analyzing condylar movements. The third problem is that the path of the condylar point depends on the position of the monitored point because mandibular movements include rotation. To avoid this problem the monitored point of the condyle has to be situated at the rotation center of the condyle. The measuring equipment with six degrees of freedom enables us to accurately locate the position of the rotation center of the condyle using an exploration algorithm. However, it has been demonstratad that the rotation center is positioned in a certain domain. This shows that the movement of the condyle is not like that of an articulator and the position of the rotation center of the condyle cannot be definitively located. If the position of the rotation center must be converged on a limited area and the rotation center of the condyle must be easy to locate, another technique for locating the position of the posterior reference point should be introduced. | |||||||
