Apatite layer-coated titanium for use as bone bonding implants

Calcium Hydroxyapatite Thin Films on Titanium Substrates Prepared by Ultrasonic Spray Pyrolysis

“…Titanium substrates high grade purity (TIKRUTAN RT-12, Deutsche Titan GmBH, plate dimensions 10 mm  15 mm  1:5 mm), were treated within two phases: first, by grinding with SiC 600 in order to produce viable surface roughness, after which they were electrochemically treated with 8% solution H 3 PO 4 during 10 minutes by using voltage of 20 V. 2,[8][9][10] Titanium substrates were then placed in a tubular furnace which was previously heated to 600 C. These conditions were selected as appropriate for the performed experiment from the calculations of the evaporation rate of water in aerosol droplets and the flow rate of aerosol droplets in the tubular reactor at given temperature.…”

“…[1][2][3][4][5][6][7][8][9] Such composites are widely used, because they have a capability to integrate directly into bone tissues through the processes of resorption and/or the processes of formation of a new bone on the surface of implant covered by calcium hydroxyapatite. [10][11][12][14][15][16] A variety of methods [17][18][19][20][21][22][23][24][25][26][27] can be used for the synthesis of calcium hydroxyapatite films, such as electrophoretic deposition, 17) electrocrystallization, 18) plasma spray deposition, 19,20) flame spray deposition, 19) magnetic field spattering, 21) deposition by aging in fluids like SBF fluids, 14) ion beam spattering, 22,23) laser beam spattering, 24) electron beam evaporation, 25) sol-gel, 26) aerosol-gel 27) and hydrothermal synthesis. 8,13) Most of these methods are expensive vacuumbased techniques, with problems related to the film homogeneity, require batch processing and usually high-vapourpressure chemicals or high purity targets as starting materials.…”

Biomimetic Coating of Precalcified Ti-6Al-4V Alloy

“…Ultrasonic cleaning, alkali and heat treatment are the usual steps used for this purpose [9]. After these steps, the alloy bears a bioactive surface [10].…”

Advances in Biomimetic Apatite Coating on Metal Implants

“…Both treated implants exhibited significantly higher failure loads compared with untreated Ti implants at all time periods and directly bonded to bone tissue during the early post-implantation period. Scanning electron microscopy-energy dispersive X-ray microanalysis (SEM-EMPA) showed a uniform calcium-and phosphorusrich layer was detected at the interface between the treated implants and bone, which indicated that Ti implants with AH treatment could induce bone-like apatite deposition in vivo, and therefore accelerated the bone-bonding behavior of implants and enhanced the strength of bone-implant bonding (Yan et al, 1997a(Yan et al, , 1997b. Titanium alloys with AH treatment showed a similar enhancement of the bonding strength (Nishiguchi et al, 1999a).…”
