摘要
目的:基于CBCT数据和计算机辅助设计软件,提出一种个性化开髓导板的设计制作方法。方法:对一名志愿者拍摄CBCT,导入MIMICS 17.0,提取出目标牙齿三维模型,分离髓腔形态,在UG8.0中设计出内管,将内管导入MIMICS 17.0插入牙齿三维模型合适位置,最后将内管和牙齿三维模型一起导入3-matic9.0,制作出个性化开髓导板。结果:成功设计出匹配21、25及26三种类型的开髓导板模型。结论:利用MIMICS、UG和3-matic三种软件相结合的方法,可以有效设计出任意洞形的个性化开髓导板,实现根管治疗中,开髓过程的个性化导板辅助。
Objective:To establish the design and manufacturing method of personalized pulp opening guide template based on CBCT data and design software.Methods:A volunteer was taken CBCT and MIMICS17.0 was imported to extract the three-dimensional model of the target tooth.The shape of the pulp cavity was separated.The inner tube was designed in UG8.0 and inserted into the appropriate position of the three-dimensional model of the tooth.Finally,the inner tube and the three-dimensional model of the tooth were led into 3-matic9.0 together to make a personalized pulp opening guide template.Results:The models of 21,25,and 26 were successfully designed.Conclusion:The combination of MIMICS,UG,and 3-matic software can effectively design the personalized pulp opening guide template with arbitrary hole shape,and realize the personalized guide template assisted pulp opening in root canal therapy.
