Avaliação de implantes ósseos de titânio e hidroxiapatita com revestimento biomimético
| Posted on: 17 dez. 2009Nowadays, there are several biomaterials used in Medicine and Dentistry which are able to rehabilitate patients and improve their quality of life. The purpose of this study was to produce a biomimetic coating onto ... -
Avaliação do reparo ósseo em ratas após implantação de hidroxiapatita carbonatada durante terapia com clodronato e zolendronato
| Posted on: 01 jan. 2014Bisphosphonates (BPs) are a class of drugs of proven efficacy in the prevention and treatment of various bone diseases that inhibit bone resorption through direct and indirect effects on osteoclasts and stimulate osteogenesis ... -
Avaliação histomorfométrica do efeito de diferentes temperaturas de síntese na resposta biológica de hidroxiapatitas carbonatas nanoestruturadas contendo alginato de sódio em defeitos críticos de calvárias de ratos
| Posted on: 01 jan. 2014Because of its bioactivity and biosorption capacity, non-ceramic carbonated hydroxyapatite containing calcium alginate (cHA) has been recommended as an alternative bone substitute to ceramic hydroxyapatite. In order to ... -
Caracterização físico-química e avaliação in vitro e in vivo de grânulos de hidroxiapatita e hidroxiapatita/betatricálcio fostato
| Posted on: 22 dez. 2012In last decades many efforts have been made to develop scaffolds to overcome the challenges of bone reconstruction. The calcium phosphate ceramics are very used because their similar chemical composition to the bone mineral ... -
Caracterização físico-química e estudo normatizado da biocompatibilidade e biodegradabilidade das membranas de hidroxiapatita-alginato-capsul e alginato-capsul para tratamento de perdas ósseas
| Posted on: 28 mar. 2011Objective: The objective of this study was to evaluate physical chemistry, in vitro and in vivo tissue response after implantation of a new alginate-membrane-capsul-Ha. Methods: The samples were characterized by scanning ... -
A hidroxiapatita contendo zinco a 0,5% como substituto ósseo: caracterização físico-química e análise normatizada da biocompatibilidade
| Posted on: 28 dez. 2009Zinc is known to play a relevant role in growth and development, it has stimulatory effects on in vitro and in vivo bone formation and an inhibitory effect on in vitro osteoclastic bone resorption. The inorganic component ... -
Impacto da temperatura de síntese na biocompatibilidade e bioabsorção de hidroxiapatitas carbonatadas nanoestruturadas
| Posted on: 01 jan. 2014Hydroxyapatite (HA) is one of the most common materials used internationally in medical applications involving bone and dental substitution/regeneration and, more recently, in cellular therapies, due to its biocompatibility ...
