Research output: Contribution to journalArticlepeer-review


The movements of the condyle with maximum mouth opening were measured by image processing of tomograms. The reference point of the condyle was determined and the distance between the reference points at closed and open positions was measured. The trajectory of the condyle during mouth opening was also analyzed by considering the shape of the temporomandibular joint. The calculated results of the condylar movements agreed with ones obtained by the image analysis. It is thought that the method presented in this paper is useful in diagnosis of temporomandibular joint dysfunction, and the condylar movements are evaluated directly from the tomograms.
