We cornstructed a small number superposition graph by computer program on a cephalometric laminagraph of five adult men and five periodontal patients who have all their teeth of maxillo-mandibular. Research was done on the sideway movements of the non-working side of the condyle which are fixed to be 1mm, 2mm and 3mm quantitative lateral movement in anterior. These results are as follows : 1. The research of the movement of the condyle was on the basis of condylar top and condylar center. The condylar movement with right and left side quantitative lateral movement of the adult men indicated a distinct straight line type. But, the periodontal patients indicated a distinct zigzag litte type. However, the moving condition of two measuring points on both subjects were much alike. 2. In spite of the condition of the occlusal surface of periodontal patients are different from that of adult men, it could be proved that the moving type of the condylar with the lateral movement is a bodily shift. 3. For both much and little quantity of lateral movement, the degree of moving obliquely of periodontal ratients' condylar was less than that of the adult men's condylar. 4. Doubted that the difference of cccclusal condition between periodontal patients and adult men were chosen on this study.
