Finite Element Simulation and Additive Manufacturing of Stiffness-Matched NiTi Fixation Hardware for Mandibular Reconstruction Surgery
Process parameters and post-processing heat treatment techniques have been developed to produce both shape memory and superelastic NiTi using Additive Manufacturing. By introducing engineered porosity, the stiffness of NiTi can be tuned to the level closely matching cortical bone. Using additively manufactured porous superelastic NiTi, we have proposed the use of patient-specific, stiffness-mat...
متن کاملMetallic Fixation of Mandibular Segmental Defects: Graft Immobilization and Orofacial Functional Maintenance
The aim of this study is to investigate the behavior of the healthy mandible under maximum molar bite force to demonstrate the problems associated with the current standard of care procedures for mandibular segmental defect reconstruction (ie, use of Ti-6Al-4V hardware and either a single- or double-barrel fibular graft). With current Ti-6Al-4V mandibular reconstruction hardware, there is a sig...
متن کاملMechanical Surface Treatments of Ti-6Al-4V Miniplate Implant Manufactured by Electrical Discharge Machining (TECHNICAL NOTE)
Present work aims at multi-mechanical surface treatment of Ti-6Al-4V based-miniplate implant manufactured by electrical discharge machining (EDM) for biomedical use. Mechanical surface treatment consists of consequent use of ultrasonic cleaning, rotary tumbler polishing, and brushing. Surface layers are analyzed employing scanning electron microscopy and energy dispersive X-ray spectroscopy. Al...
متن کاملA study on the mechanical characteristics of the EBM-printed Ti-6Al-4V LCP plates in vitro
PURPOSE The electron beam melting (EBM) Ti-6Al-4V material technology has been developed over a short time period. It was introduced through a research to develop Ti-6Al-4V implants for patients, but EBM printed locking compression plates have not been used for clinical implants. The main purpose of this study is to find whether the EBM Ti-6Al-4V plate suit for clinical implants. METHODS Firs...
متن کاملFabrication of Porous Segments Using Ti-6Al-4V Chips for Orthopaedic Applications
Different methods have been evaluated for manufacturing the porous Ti6Al4V alloys according to decreasing stress shielding phenomenon and increasing mechanical compatibility between the metallic components and the host tissue. For this purpose, in this work Ti6Al4V alloy chips were pressed under 400 MPa pressure and then samples were categorized and heated into two groups at 1000 and 1150℃ unde...
