In this study, metal 3D printing technology was used to create lattice-shaped test specimens of orthopedic implants determine the effect different lattice shapes on bone ingrowth. Six were used: gyroid, cube, cylinder, tetrahedron, double pyramid, and Voronoi. The lattice-structured produced from Ti6Al4V alloy using direct laser sintering with an EOS M290 printer. implanted into femoral condyles sheep, animals euthanized 8 12 weeks after surgery. To degree ingrowth for implants, mechanical,...
Additive manufacturing (AM) technologies are potential future-shaping solutions throughout many special applications in medicine. The mechanical behaviour of the related materials has not yet been fully explored. Here we compared five different industrial quality 3D printing produced using various AM processes that can be potentially used limb-prosthetic development. We focused on anisotropy and structural properties these by static dynamic testing methods electron microscopy imaging. Both...
Abstract All types of cranioplasty techniques restore the morphology skull and affect patient aesthetics. Safe easy are required to enhance patients’ recovery rehabilitation process. We propose a new method cranioplasty. The 3-dimensional (3D) reconstruction thin-layer computed tomography (CT) scan was used reflect intact side onto defect subtract overlapping points from one another. In this way, 3D model planned implant can be built in shape size. precise fit checked by printing defective...
Monolithic silica aerogels are nanostructured solids characterized with exceptionally high porosity and specific surface area. Although their strength can be improved by treatment polymers, none of them has been tested yet as a filler in biocompatible polymer composites. The new aerogel–poly(methyl methacrylate) composites were prepared free radical bulk polymerization neat methyl methacrylate the presence natural functionalized at 60°C, using cumene hydroperoxide initiator 4, N ,...
The development of an efficient procedure for 3d modeling and finite element simulation metal foams is one the greatest challenges engineer researchers nowadays. Creating CAD model alone a demanding engineering task due to its extremely complex geometry, proper analysis process still in center research. increasingly widespread application foams, e.g. vehicle medical industry, requires this knowledge design phase. A closed-cell foam studied using different analyzing methods where aim collect...
In Brief Study Design. Different geometrical and biomechanical evaluations were performed to determine the axial rotational axis of thoracic spine. Objective. Our research group has been dealing with determination Here, we would like present experimental results our trials. With experiments, are trying evaluate contradictions related literature. Summary Background Data. state, know quite a lot about biomechanics healthy pathologic spines. Nevertheless, for seemingly simple question position...
Abstract Our objective was to examine the load‐bearing capacity of transverse processes human cadaveric thoracic vertebrae vertical loads and axial rotation moments (i.e., moment applied in plane). A secondary effect attached rib stumps. We wanted demonstrate that process is durable enough support CAB hook—a complementary hook CD system—and can handle load or during correction scoliosis. used 107 removed from 10 cadavers. They were prepared vertebral pairs, fixed into a material testing...
The development of an efficient procedure for three-dimensional modelling and finite element simulation metal foams remains one the greatest challenges engineers.The numerical determination compressive properties foam structure is a demanding engineering task indispensable design purposes.In load-bearing structures, elastic behaviour under working circumstances must be considered calculations on actual its precise geometrical necessary.Closed-cell aluminium produced from Duralcan F3.S.20S...
This study aims to present a new technique, the roof step cut (RSC), for acetabular augmentation of hip dysplasia.Between December 2008 and March 2020, we applied RSC technique in total 48 hips 41 patients (2 males, 39 females; mean age: 50.1±9.5 years; range, 30 75 years) with Hartofilakidis type A, B, C dysplasia. The uses L-shaped graft from femoral head. is partially inside acetabulum on lateral aspect ilium. It fixed two screws at 45° angle allowing simultaneous distalization covering...
