“…The present in vivo study confirms the bioactive property of RBBM blasting to improve the performance of the PEEK implant. The RBBM technology applied to polymer as PEEK for biomimetic surface treatment [18], confirms the interest in the future surface treatment of osteosynthesis and maintain on time of bone contact. These data confirm the efficient effect of RBBM blasting on earlier bony integration, due to a soon spreading of osteogenic cells on this micro-structured clean surface.…”

It was demonstrated that microstructured surfaces improve cell spreading and bone ingrowth. Particularly, the surface roughness modulates the osseointegration of orthopaedic and dental implants. We have developed an innovative grit blasting process using Biphasic Calcium Phosphate, a Resorbable Biocompatible Blast Media (RBBM). PEEK is biocompatible but an inert material, involving no direct bone bonding. Implants coming from a rabbit experimental study, were processed for X-rays Micro tomography. Light microscopy and SEM were performed.It was demonstrated in this study that the surface treatment on PEEK improve the quality of bone architecture in direct contact with the sample surface, compared to the classical surface of PEEK. These data demonstrate that PEEK rough surface obtained by RBBM blasting maintain high biocompatibility and bone osteoconduction, and promote higher stability of the implant.

Surface roughness modulates the osseointegration of orthopaedic and dental titanium implants. High surface roughness is currently obtained by blasting of titanium implants with silica or aluminium abrasive particles. This process includes into the surface abrasive particles and may cause the release of cytotoxic silica or aluminium ions in the peri implant tissue. To overcome this drawback, we currently develop an innovative gridblasting process using Biphasic Calcium Phosphate (BCP) particles (RBBM Resorbable and Biocompatible Blast Media) to generate biocompatible roughened titanium surface. This work present the technique of blasting using RBBM particles to provide a roughened surface which does not release cytotoxic elements and (ii) to assess the effects of such a roughened surface for bone osteointegration in critical size rabbit defect. Our results demonstrate that resorbable biphasic calcium phosphate abrasive particles can be used to create titanium surface roughness. This grid blasting process increases surface roughness of titanium implants and offers a non cytotoxic surface for rapid and efficient osteointegration.

“…Empero, «Le chocolat est en revanche peu prisé des chanoines» franceses, hasta el punto que «il se diffuse lentement dans la societé» gala 60 -de hecho, los canónigos franceses «confirment le schéma génerale de diffusión de ces produits». 61 En España, en Burgos en concreto, los capitulares catedralicios, sin embargo, se decantaron por la degustación de chocolate de manera habitual, hasta tal punto que desde, mediados del xvii y en especial en el Setecientos, «la aristocracia y el alto clero lo tomaban como desayuno y merienda». «Consumirlo diariamente llegó a ser una auténtica obsesión de nobles y clérigos y se convirtió en un símbolo de estatus social: los aristócratas no podían prescindir de su taza de chocolate cada mañana, ni siquiera los días de ayuno», por encima incluso de las controversias más disparatadas 62 .…”

RESUMEN: La distribución y el consumo de chocolate invadieron, como una «fiebre» persistente, la cultura material y las prácticas alimenticias en el Setecientos. Las viviendas castellanas se dotaron, de manera creciente, de chocolateras y mancerinas, en las cuales verter el ansiado y nutritivo chocolate. El cacao llegaba, con más o menos prodigalidad, a las lonjas y tiendas de las ciudades y a las alacenas y despensas de las viviendas. Los clérigos no fueron ajenos a ese proceso e incluso protagonizaron una problemática colectiva, la del Cabildo catedralicio, con el objetivo manifiesto-preñado en muchas ocasiones de ansiedad y de tirantez con la empresa suministradora y con las autoridades municipales y estatales-de conseguir una logística sostenible de la materia prima, el cacao, para sus hogares.
