 AB: The purpose of this investigation was to know correlation of mean values between centric occlusion and centric rela tion by the cephalogram in Angle's Class Ⅰand Ⅲ malocclusion subjects. 22 adults with Angle's Class Ⅰ malocclusion (17 men and 5 women, 21 to 27 years of age) and 14 adult with Angle's cl ass Ⅲ malocclusion (10 men and 4 women, 21 to 27 years of age) were selected form the dental students in Yonsei Univers ity. Each subject was given two lateral cephalometric radiographics and cephalometric analysis was performed. All data form these analyses was recorded and statistically processed with CYBER computer system.
 The results were obtained as follows:
 1. There was a strong positive correlation between centric occlusion and centric relation in all subjects with Angl e's Class I and III malocclusion.
 2. In Angle's Class I malocclusion, measurements in lower facial height revealed significant difference between ce ntric occlusion and centric relation (p<0.05). in angle> 3.When the mandible was movement was 1.27mm (0.2-2.8mm) in Angle's Class I malocclusion, 1.70mm(0.55-4.15 mm) in Angle's Class III malocclusion, and 1.44mm (0.2- 4.15mm) in all subjects.
