Abstract：AIM:To propose a new method for the measurement of oral cavity proper by using 3D recon-struction in adult female with skeletal bimaxillary protrusion.METHODS:CT data of 15 adult females with nomal oc-clusion and 15 with skeletal bimaxillary protrusion were obtained.The distinctions of oral cavity proper in the 3D model were marked and then separated layer by layer.MIMICS automatically gave the measurement results of oral cavity vol-ume and the related indexes.RESULTS:The oral cavity proper volume of the subjects with bimaxillary protrusion and normal controls were (68.3 +9.30)cm3 and (62.99 +10.10)cm3 respectively(P<0.05).Sagittal projection are-a,oral cavity proper length,height and mandibular length also showed significant differences (P<0.05),but no sig-nificant difference was observed in width (P>0.05).CONCLUSION:3D reconstruction is a feasible measurement method for oral cavity proper.Data in this study will provide a theoretical basis for further study.
