Evaluation of the interface between bone and titanium surfaces being blasted by aluminium oxide or bioceramic particles

Abstract

The surface structure, in particular the surface roughness, and the surface chemistry of titanium implants influence their anchoring in bone. The aim of this study was to analyse metal-bone contact (MBC) after modification of the implant surface, using different materials for blasting. The surface modification of titanium was produced by blasting it with particles made of Al2O3 or bioceramics. The biological effects were then investigated experimentally using 27 rabbits, analysed after 7, 28 and 84 days after the implantation of titanium cylinders treated accordingly. The MBC showed a tendency for more bone after bioceramics were used as a blasting material, compared to Al2O3.

Enhanced osteoconductivity of micro‐structured titanium implants (XiVE S CELLplus™) by addition of surface calcium chemistry: a histomorphometric study in the rabbit femur

“…The mean BIC% of the XIVE S CELLplust implants appeared greater at 6 weeks than that for other micro-rough-or potentially bioactive-surfaced implants placed in rabbit femurs (Sul et al 2002;Mohammadi et al 2003;Susin et al 2008). At 12 weeks, high BIC% was reported for micro-rough implants grit-blasted with Al 2 O 3 (76.4%; Hayakawa et al 2000) or bioceramic particles (63%; Mueller et al 2003), and for crystalline calcium phosphate-coated implants (84.7%; Hayakawa et al 2000) when implanted in rabbit cancellous bone.

A review of the surface modifications of titanium alloys for biomedical applications

“…These studies confirm that roughening of the titanium dental implants increases their mechanical fixation to the bone, but not their biological fixation. [18][19][20] A. Karacs et al 21 investigated the morphology of machined, blasted and laser-treated surfaces of titanium. The Al 2 O 3 blasted surface has a unique surface morphological characteristic that enhances the osseointegration process.…”

Nanostructured Biomaterials for Tissue Engineered Bone Tissue Reconstruction

“…Blasting represents one of the approaches for roughening the titanium surface, and it makes use of hard ceramic particles, such as alumina [30], titanium oxide, and calcium phosphate particles [31]. Figure 1(a) shows an image of alumina blasted titanium surface obtained by scanning electron microscopy (SEM).…”
