Abstract 62 cases of the Zhuangs normal occlusion in permanent dentitionhave been given a cephalomatric X-ray examination, the value of APDI was 81.55±3.76 andthe ODI 74.84±3.66. The results indicated the presence of different ODI value between theZhuangs and the majority Hans. The results suggested the difference was related with thepalative surface inclining downward and forward, low mandibular plane angle(FMA 26±3.41),shortage in the low facial height (ANS-Me 65.5±1.55mm) and the considerable highincidence of deep overbite and overjet. Meanwhile, The article explained elabrately theeffect and significance of the value of APDI and ODI in the clinic diagnosis andtreatment.
