Bioactive glass-derived trabecular coating: a smart solution for enhancing osteointegration of prosthetic elements.
In this work, the use of foam-like glass-ceramic scaffolds as trabecular coatings on ceramic prosthetic devices to enhance implant osteointegration is proposed. The feasibility of this innovative device was explored in a simplified, flat geometry: glass-ceramic scaffolds, prepared by polymeric sponge replication and mimicking the trabecular architecture of cancellous bone, were joined to alumin...
متن کاملEnhanced osteointegration of orthopaedic implant gradient coating composed of bioactive glass and nanohydroxyapatite.
We conducted histologic and histomorphometric studies to evaluate the osteointegration of gradient coatings composed of bioactive glass and nanohydroxyapatite (BG-nHA) on titanium-alloy orthopaedic implants and surrounding bone tissue in vivo. Titanium-alloy implants with a gradient coating (gradient coating group), uncoated implants (uncoated group), and implants with a conventional hydroxyapa...
متن کاملEFFECT OF TiO2 ADDITION ON BONDING STRENGTH OF CaO-P2O5 Na2O-TiO2 BIOACTIVE GLASS CERAMIC COATING
The effect of titanium dioxide addition on bonding strength of CaO-P2O5 -Na 2O-TiO2glass-ceramic system was investigated as a coating on titanium substrate. Thus, different amounts of TiO2 (2, 3.5 and 5mol %) were added to the base glass batch composition. The prepared glaze slips were applied on the substrate by dip coating method, dried and then heat treated at various temperatures. After tha...
متن کاملSmart soft-templating synthesis of hollow mesoporous bioactive glass spheres.
Hollow bioactive glass spheres with mesoporous shells were prepared by using dual soft templates, a diblock co-polymer poly(styrene-b-acrylic acid) (PS-b-PAA) and a cationic surfactant cetyltrimethylammonium bromide (CTAB). Hollow mesoporous bioactive glass (HMBG) spheres comprise the large hollow interior with vertical mesochannels in shell, which realize large uptake of drugs and their sustai...
متن کاملPreparation of nano bioactive glass and investigation of its properties in different volume of solution
Nano Bioactive glass material of the type CaO–P2O5–SiO2 was obtained by the sol-gel processing method at considerably lower temperatures than required for conventional melting methods. As a new modification, volume of solution was changed in order to investigate its effects on the properties of bioglass samples. The obtained material was characterized by X-ray powder diffraction (XRD), surface ...
