3D打印牙模与传统石膏牙模的比较研究
Comparative analysis between 3D printed dental casts and traditional plaster casts
摘要
Abstract
With the development of digital technology in the stomatology application and digital fabrication of dentures will be the trend in the future.During the process of digital fabrication of dentures ,3D printed dental casts will replace traditional plaster casts.Preparing standard cylinder and rectangular specimens by 3D printing and pour plaster impression and measuring the me-chanical properties and surface roughness of specimens are indirect comparison with 3D printed dental casts and traditional plaster casts.Besides the dimensional accuracy of them are analyzed in comparison .Compared with traditional plaster casts ,3D printed dental casts are less in hardness ,but better in compressive strength ,bending strength and surface roughness .The dimensional ac-curacy of 3D printed dental casts is similar to traditional plaster casts ,but the consistency of 3D printed dental casts is better . Comparative analysis between 3D printed dental casts and traditional plaster casts ,the study shows that 3D printed dental casts which are more superior to traditional plaster casts ,can fully replace traditional plaster casts for digital fabrication of dentures .关键词
