摘要: 目的:验证二维DR数据形变重建的颅面硬组织模型的准确性,以期为治疗方案确定、手术方法选择和提高医患交流水平提供平台。方法:对7名志愿者分别进行基于二维DR数据的形变建模和CT建模,通过测量64项描述颅面硬组织特征的项目,进行直观重叠比较和客观分析。采用SPSS17.0软件包对数据进行配对t检验。结果:58项测量项目无显著差异,形变建模和CT建模的一致性很高。结论:基于二维DR数据形变建模的颅面硬组织精确性高,偏差基本在允许的范围内,完全可以满足临床诊断和治疗的需要。该三维重建系统能够在临床上应用。

Abstract: PURPOSE: In this study, we validated the precision of 3-D craniofacial reconstruction of hard tissues based on 2-D digital cephalometric radiograph, in order to increase the level of orthognathic diagnosis and treatment, and promote communication between doctors and patients. METHODS: Deformation modeling based on 2-D digital radiograph and CT modeling was performed in 7 volunteers. 64 items were measured which described craniofacial hard tissue structure, intuitive overlapping and objective analysis were conducted. SPSS 17.0 software package was used for paired t test. RESULTS: 58 measurement items were not statistically different. Deformation modeling and CT modeling of the consistency was very high. CONCLUSIONS: Deformation modeling based on 2-D digital radiograph of craniofacial hard tissues is accurate and reliable, and basic deviation was within the allowed range. This 3-D reconstruction system could be used in clinic for diagnosis and operation simulation.
