Electron beam melting (EBM) and selective laser (SLM) are two advanced rapid prototyping manufacturing technologies capable of fabricating complex structures geometric shapes from metallic materials using computer tomography (CT) Computer-aided Design (CAD) data. Compared to traditional used for products, EBM SLM alter the mechanical, physical chemical properties, which closely related biocompatibility products. In this study, we evaluate compare biocompatibility, including...
The study was designed to fulfill effective work-flow fabricate three-dimensional mesh titanium scaffold for mandibular reconstruction. 3D based on a volunteer with whole mandible defect. (1) acquisition of the CT data; (2) design computer aided (CAD) and finite element analysis (FEA). pore size intervals best mechanic strength also calculated using FEA. (3) fabrication electron beam melting (EBM); (4) implantation surgery. case recovered well, without loosening rejection. Additionally, 12...
Bone fusion of defect broken ends is the basis functional reconstruction critical maxillofacial segmental bone defects. However, currently available treatments do not easily achieve this goal. Therefore, study aimed to fabricate 3D-printing titanium grid scaffolds, which possess sufficient pores and basic biomechanical strength facilitate osteogenesis in order accomplish mandibular The clinical trial was approved supervised by Medical Ethics Committee Chinese PLA General Hospital on March...
The isothermal oxidation behavior of single crystal DD6 film-cooling blades was investigated. tests were conducted at 1050 °C, and the phase analysis performed by XRD, while SEM (EDS) employed to observe material. In addition experimental studies, a numerical simulation using three-dimensional finite element based on Abaqus software (Version 6.13) implemented model growth stress in specimens during test. obtained results showed that average rate rose with increments film hole spacing, up...
Compared with CAD/CAM, fused deposition modeling (FDM) 3D printing technology is simple and safe to operate has a low cost high material utilization rate; thus, it widely used. The present investigation aimed evaluate the mechanical properties fit of polyetheretherketone (PEEK) removable partial dentures (RPDs) constructed by FDM. We analyzed PEEK samples prepared FDM, milling, or injection molding. RPDs were designed finite element analysis models was maximum stress strain in RPDs, cortical...
To determine the benefit to postoperative facial function of intraoperative nerve monitoring (IFNM) during recurrent pleomorphic adenoma (RPA) parotid surgery.Cohort study with planned data collection.Chinese PLA General Hospital.Fifty-eight RPA parotidectomies were performed between 2004 and 2012. Recurrence was confirmed by histopathologic examination. None patients had preoperative palsy. Electromyography-based IFNM used in 28 patients; 30 unmonitored. The durations surgery severity palsy...
Two In-MOFs (In-MOF 1 and In-MOF 2) were synthesized by using two different pyridine carboxylic acid ligands. The MOFs have certain gas adsorption separation capacity, which is determined the structure, adjustable porosity.
The objective of the present study was to investigate whether NOD-like receptor family pyrin domain-containing 3 (NLRP3) and absent in melanoma 2 (AIM2) inflammasomes pathways were involved an experimental model fibroblast activation named nemosis, which used mimic circumstances without bacteria stimulation.
In this study, the K6509 cobalt-base superalloy were heat treated at different temperatures and microstructure was detected by scanning electrical microscopy probe micro-analyzer. as-cast K6509, MC carbides are present as a discrete, blocky dispersion with well-distributed Chinese script morphology eutectics (γ+M23C6) (γ+M7C3) can be seen. With temperature increasing, arise degeneration. Below 1150oC, script-like is dominant; reaching 1200oC, particle block of 1250oC, few present. alloy,...
Icariin (ICA), a main active ingredient of Herba Epimedium, could promote bone formation, inhibit resorption and alleviate inflammatory responses. The aim this study was to investigate the effect ICA on inhibition bacteria associated with peri-implantitis, fabricate calcium phosphate cement (CPC) ICA-loaded gelatin microspheres (GMs) as local drug delivery system efficiently promoting formation alleviating inflammation.In study, exhibited antibacterial activity against P. gingivalis MIC...
Premature failure of a deep-groove ball bearing used in an aeroengine governor took place during service. In this paper, the mode and root cause were studied by macroscopic microscopic examination, metallographic analysis, hardness test, calculations contact stress L10 life, flatness measurement comparative experiment. The results show that modes inner ring raceway steel balls are fatigue spalling, outer wear cage is fracture. direct unqualified machining process spring end face high...
