2021年11月1日 · Trabecular bone, or cancellous bone, is a lattice-like structure that allows bone to maintain its strength, while being relatively lightweight. Trabecular bone is primarily located at the articulating ends of long bones and in the body of short bones, which allows for improved load transfer through these structures.

In this work, we used lithography-based ceramic manufacturing of lattice structures to produce scaffolds from tricalcium phosphates (TCP) and compared them in vivo to congruent titanium scaffolds manufactured with the identical computer-aided design data to look for material-based differences in bony healing.

2024年1月1日 · In this study, we have explored the potential application of three-dimensional (3D) lattice-structured materials in the bone scaffold implants by investigating the mechanical strength and porosity of various strut-based lattice designs.

2023年2月1日 · The aim of this study is the morphological and mechanical characterization of the novel unit cell to check its suitability to the biomechanical field, along with its comparison with other lattice structures currently used as bone scaffold.

2022年10月14日 · Lattice structures for implants can be printed using metal three-dimensional (3D)-printing and used as a porous microstructures to enhance bone ingrowth as orthopedic implants. However, designs...

In this study, metal 3D printing technology was used to create lattice-shaped test specimens of orthopedic implants to determine the effect of different lattice shapes on bone ingrowth. Six different lattice shapes were used: gyroid, cube, cylinder, …

There are two types of mature bone - compact (lamellar) and spongy (trabecular or cancellous). Compact bone is characterized by the regularity of its collagen fibers. Spongy bone consists of a lattice of branching bony spicules, known as trabeculae, which are …

2017年8月10日 · Here, a computational approach was developed for modeling scaffolds with lattice structures of eight different topologies and assessing properties relevant to bone tissue engineering applications. Evaluated properties include porosity, pore size, surface-volume ratio, elastic modulus, shear modulus, and permeability.

2019年2月20日 · For bone tissue engineering purposes, scaffolds can readily be designed as 3D data model and realized with titanium known for its excellent osseointegration behavior. The microarchitecture, that is, design with submillimeter features, of additively manufactured scaffolds is in many cases a lattice structure.

2023年7月11日 · Composite scaffolds with FCC structures are promising for bone tissue engineering. Mechanical performance is crucial for biomedical applications of scaffolds.
