Introduction
Dr. Criseida Ruiz has experience in the ceramic biomaterials research line, with applications in the regeneration of trabecular and cortical bone, developed chemical synthesis, mechanosynthesis, powder metallurgy, polymer foaming, use of porogens and 3D printing. In addition to manufacturing and physical, chemical, mechanical, and in vitro characterization of resorbable ceramic prostheses, without neglecting the synthesis and characterization of bone cements from the recycling of products.

Article
Tricalcium phosphate beta phase (β-TCP) is a promising bioceramic that stimulates the formation of bone tissue due to its chemical composition, which is similar to those of bones and teeth, showing promising osseointegration and osteoinduction results. Its main applications are in the regeneration and stimulation of cortical and trabecular bone tis...

Scaffolds have proven to be an excellent option for the regeneration of bone tissues; since they present excellent results of architecture, composition, and functionality. Therefore, scaffolds can be used as implants to repair bones and show guided regeneration, allowing complete restructuring of damaged tissue, as well as allowing the site where t...
Article
There are numerous methods for producing scaffolds to be applied in bone tissue engineering. However, the best method of scaffold production is essential to consider, with respect to their chemical composition and mechanical and structural properties, so that debris is not produced when the scaffolds are evaluated in vitro or in vivo. The primary a...
Article
Scaffolds for bone tissue applications have been an outstanding alternative to repair and regenerate bone tissue defects caused by traumas or illness. There are many methods available to fabricate porous scaffold such as solvent casting, gas bubble, phase separation, electrospinning, particle-leaching, among others. The particle-leaching technique...

Mechanical properties of metallic foams are highly dependent on the characteristics of porosity. In the case of foams manufactured using space holder particles (SHPs), parameters such as percentage porosity, pore size and cell wall thickness are directly contingent on the SHP used. In this work, different fractal distributions of SHPs were introduc...
Article
Scaffolds have been showed to be an option for bone tissue regeneration, owing to their excellent results in architecture design, composition, and functionality. Consequently, scaffolds can function as implants to repair bones and guide regeneration, enabling the complete restoration of tissue functionality at their implantation site. In the presen...
Article
The present study estimates the effect on Young’s modulus of the percentage and thickness of iron hollow spheres reinforcing copper syntactic foams. The resulting materials were modeled by inserting hollow spheres in a random arrangement, using a combination of Discrete Element Method (DEM) for generating the sphere location coordinates and Finite...
Article
β-Tricalcium phosphate (β-TCP) is one of the most investigated calcium phosphates to be used in bone tissue regeneration. Nowadays, β-TCP has been synthetized by different methods that allow obtaining different morphologies with chemical compositions similar to the bone tissue, broadening the possibilities of use. In this work, β-TCP powders were o...

Tricalcium phosphate scaffolds reinforced with bioglass were characterised morphologically, physically, and mechanically. The scaffolds were fabricated through powder technology and the polymer foaming technique using 80 wt-% of β-TCP and 20 wt-% of phosphate-based bioglass doped with zirconia in various amounts (0, 0.25, 0.5, 0.75, and 1.0 wt-%)....

Bone tissue engineering is an excellent alternative to reduce bone disorders and conditions, by inducing new functional bone regeneration starting from the synthesis of the biomaterials and then the combination of cell and factor therapy. In the present contribution, the scaffolds were made with a ratio of 80 wt.% of β-TCP and 20 wt. % of phosphate...
Conference Paper
Full-text available
Currently, one of the biggest challenges in the area of bone tissue regeneration has been the creation of scaffolds that have similar characteristics and composition to natural bone. β-TCP scaffolds have been successfully used as an alternative for regenerative purposes. Nonetheless, tricalcium phosphate scaffolds have low mechanical properties. In...

Highly ordered through-hole anodic porous alumina membranes were fabricated by electrochemical oxidation of aluminum in a controlled two-step process. A teflon dispositive was used to ensure single side anodization. Under the most appropriate condition for the fabrication of ideally ordered anodic aluminum oxide (AAO), the voltage used was 15 V dur...
