主 题：orbital blowout fracture absorbable material finite element analysis 3D printing technology
摘 要：AIM:To investigate the biomechanical properties and practical application of absorbable materials in orbital fracture ***:The three-dimensional(3D)model of orbital blowout fractures was reconstructed using Mimics21.0 *** repair guide plate model for inferior orbital wall fracture was designed using 3-matic13.0 and Geomagic wrap 21.0 *** finite element model of orbital blowout fracture and absorbable repair plate was established using 3-matic13.0 and ANSYS Workbench 21.0 *** mechanical response of absorbable plates,with thicknesses of 0.6 and 1.2 mm,was modeled after their placement in the *** patients with inferior orbital wall fractures volunteered to receive single-layer and double-layer absorbable plates combined with 3D printing technology to facilitate surgical treatment of orbital wall ***:The finite element models of orbital blowout fracture and absorbable plate were successfully *** element analysis(FEA)showed that when the Young’s modulus of the absorbable plate decreases to 3.15 MPa,the repair material with a thickness of 0.6 mm was influenced by the gravitational forces of the orbital contents,resulting in a maximum total deformation of approximately 3.3 ***,when the absorbable plate was 1.2 mm thick,the overall maximum total deformation was around 0.4 *** half-year follow-up results of the clinical cases confirmed that the absorbable plate with a thickness of 1.2 mm had smaller maximum total deformation and better clinical ***:The biomechanical analysis observations in this study are largely consistent with the clinical *** use of double-layer absorbable plates in conjunction with 3D printing technology is recommended to support surgical treatment of infraorbital wall blowout fractures.
