Characterization of bismuth-silicate soles
(Journal of Physics: Conference SeriesInglaterra, 2019-11-29)
The bismuth silicate compound was synthesized by the sol-gel method from bismuth nitrate pentahydrate and tetraethoxysilane, as precursors. The sol-gel method is attractive because the processes for obtaining oxides are ...
Surface modification using the biomimetic method in alumina-zirconia porous ceramics obtained by the replica method
(Wiley-Blackwell, 2018-10-01)
The modification of biomaterials approved by the Food and Drug Administration could be an alternative to reduce the period of use in humans. Porous bioceramics are widely used as support structures for bone formation and ...
Sterilization of scaffolds of calcium phosphates and bacterial cellulose for their use in tissue regeneration
(2021-01-01)
The development of biomaterials for the regeneration of tissues is of great importance, and their demand increases every day, due to the increase of the aging population, the expectation, and quality of life, as well as ...
Statistical evaluation of the effect of ultrasound on the synthesis of calcium phosphates
(Biointerface Research Applied Chemistry, 2019-10-15)
Calcium phosphates are widely used materials in tissue engineering due to their biocompativility and bioactivity. They are present in the bone along with the hydroxyapatite, which facilitates its use as a bioceramic. The ...
Preparation, characterization and biological studies of β-TCP and β-TCP/Al2O3 scaffolds obtained by gel-casting of foams
(2017-07-01)
Replacement tissues for tissue engineering can be produced by seeding human cells onto scaffolds. In order to guarantee adequate bio-compatibility, porosity and mechanical resistance for promoting cellular growth, proliferation ...
Efeito dos parâmetros de retificação no acabamento superficial de cerâmicas avançadas
(2016-10-01)
The advanced ceramics shows a wide application, from components for the electronic industry to implants and prostheses. In the last decades the bioceramic has been drawing attention in applications such as bone prostheses ...
Endodontic Perforation Closure by Five Mineral Oxides Silicate-Based Cement with/without Collagen Sponge Matrix
(2021-01-01)
Endodontic perforations are common accidents that occasionally happen as a result of misuse or difficult anatomy of some teeth; it may lead to teeth loss unless a good management is provided. Bioceramic (silicate-based) ...
The controlled release of antibiotic by hydroxyapatite: Anionic collagen composites
(Blackwell Science, 1998-03-01)
Major problems with the treatment of osteomyelitis are associated with poor antibiotic distribution at the site of infection due to limited blood circulation to the skeletal tissue. Improved treatment procedures have been ...
Cytotoxicity assessment of three endodontic sealing cements used in periapical surgery. In vitro study
(Facultad de Odontología, 2017)
