In Vitro and In Vivo Evaluation of Lyophilized Bovine Bone Biocompatibility

Abstract: INTRODUCTION: The use of bone grafts in orthopedic, maxillofacial and dental surgery has been growing. Nevertheless, both fresh autografts and frozen allografts have limitations, and therefore, alternative synthetic or natural biomaterials, such as processed and lyophilized bovine bone graft have been developed. OBJECTIVE: To evaluate in vitro and in vivo biocompatibility of lyophilized bovine bone manufactured in a semi-industrial scale, according to a modifical protocol developed by the authors. METHODS: Sam… Show more

“…This study contributes information that is extremely relevant to the use of LBG, produced according to the protocol developed by the main author, in humans, since it demonstrates its osseointegration. Previous studies endorse the use of this LBG both in animals (15,16) and in humans (2,5,18) . Meyer et al (21) brought forth the first data relating to histological osseointegration in relation to LBGTutobone ® -in humans.…”

“…Although there is a shortage of data regarding xenograft use in RTHA, clinical complications have not been observed, except for those complications expected with the use of allografts or xenografts in general, since physical and chemistry characterizations have confirmed both bones are alike 26,27 . The obtained results, therefore, have shown that the use of freeze-dried bovine bone grafts does not cause adverse reactions of any kind, further supporting their safety.…”

“…parte celular e possíveis agentes infecciosos. Os desenvolvedores deste material acreditam que esta preservação da maioria dos componentes do enxerto proporcione um melhor desempenho mecânico e biológico do produto na regeneração óssea (GALIA et al, 2008).…”

“…Para diminuir ainda mais a quantidade de gordura residual foram feitas novas alterações neste protocolo, aumentando a exposição ao clorofórmio e metanol para vinte e cinco dias, lavagem em lavadora ultrassônica para remover os restos orgânicos, imersão em peróxido de hidrogênio por uma hora e imersão em hipoclorito de sódio, reduzindo assim, a quantidade de gordura de 1% para menos de 0,06%. Esta redução da gordura e da quantidade celular remanescente no enxerto torna-o mais seguro e com as mesmas propriedades mecânicas anteriores (DUARTE; SCHAEFER, 2000;GALIA et al, 2008 Através da análise por microscopia eletrônica de varredura observou-se que o OBIN conserva sua estrutura típica de osso medular, com poros interconectados, essenciais para a migração celular durante a regeneração. Em outro tipo de análise, a de difração de raios x, observou-se picos característicos de hidroxiapatita, mostrando que o processamento não afeta a fase mineral do osso original (GALIA et al, 2011).…”
