Steiner Analysis Of Cephalometric Normal Values For Korean Adults With Normal Occlusion In Yanbian Area

Objective The aim of present study was to establish cephalometricnormals standard value for korean in Yanbian China by means of Steineranalysis.Methods 72 cases of Korean adults in Yanbian with normal occlusionswere selected, standard lateral cranial X-ray exposure and cephalometricSteiner analysis were carried out, then comparation among with Hannationalities in Beijing China and Korean in Seoul, Republic of Korea.Results 1,Cephalometric Steiner normal standard values, standarddeviation and Cheveron analysis chart were established. 2,There weresignificantly differences on (?)-NB angle (male＞female) and GoGN-SNangle(female＞male, p＜0.05, respectively). 3. There were significantdifferences on SNA,SNB,ANB,SND,1-NA (mm),(?)-NB (exceptwoman) compared with the those of the same age group Koreanspresented by In-Chool Park (p＜0.01). 4. Compared with the same agegroup of Beijing, in SNA,SNB,ANB,SND,PO-NBmm,1-NA,SLmmthe value of Yanbian Koreans was higher than that of people in Beijing,while the value of (?)-NB(mm), (?)-NB(except man ), 1-(?), Occl-SN,GoGn-SN were lower than those of people in Beijing, respectively (p＜0.01).ConclusionThere is a significant difference between Korean male and female withnormal occlusions in Yanbian area, and it has its own character comparedwith other nations and areas. Present investigation filled the blank ofstomatological data in Yanbian Korean autonomous prefecture region. Inthe mean while, it served a completed and supplemented the normalocclusion data of different nationalities in China. The experiment alsoprovided the reference for clinic and scientific research of orthognathicsurgeon. At the same time, the experiment provided the evidence for thefurther research.
