“…Acid treatment of the surfaces of titanium implants results in uniform roughness with micro pits ranging in size from 0.5-2 µm, increase in surface area, and an improvement in bioadhesion. Acid treatment of implants enhances osseointegration as these implants can facilitate migration and retention of osteogenic cells at the implant surface (Takeuchi et al, 2003). Alkali treatment involves immersion of the implants in either sodium or potassium hydroxide followed by heat treatment by rinsing in distilled water.…”

Titanium (Ti) implants are extensively used in a number of biomedical and dental applications.This work introduces Ti into the glass phase of a zinc based Glass Polyalkenoate Cement (GPC) and investigates changes in handling and mechanical properties considering two molecular weight polyacrylic acids (PAA), E9 and E11. Considering the handling properties, the working time (T w ) increased from 50s E9 , 32s E11 (BT 101, Ti-free) to 169s E9 , 74s E11 with TW-Z (highest Ti content) respectively. The setting time (T s ) increased from 76s E9 , 47s E11 (BT 101) to 303s E9 , 232s E11 with TW-Z respectively. Ti was also found to have a significant increase on both compressive (σ c ) and biaxial flexural strength (σ f ), where σ c increased from 36 MPa E9 , 56 MPa

“…Moreover, a great deal of carbon contamination was detected in RGD/Ti relative to P-Ser/Ti and P-RGD/Ti ( Table 2). The HCl-based decontamination method used in this study 19) should facilitate stable chemical modification of the Ti surface and promote progressive binding of amino acids to the modified surface. On this note, Krozer et al 20) reported that the bonding of amino-alcohol, used for cleaning contaminated implant surfaces, was stronger to an acid-treated Ti surface than to an anodically oxidized Ti surface.…”

“…Five pure titanium disks (diameter: 5.8 mm, thickness: 2 mm; JIS 2; GC, Tokyo, Japan) for each compound were cleaned by ultrasonic treatment with 10 N HCl (Katayama Chemical, Osaka, Japan) for 30 min, followed by ultrasonic rinsing with ultrapure water (MilliQ water: >18 MΩcm) for another 30 min 19) . These disks were then immersed in either 50 mM P-RGD, 50 mM RGD or 50 mM P-Ser at 37°C for 12 h. The disks exposed to P-RGD, RGD and P-Ser individually (P-RGD/Ti, RGD/Ti and P-Ser/Ti) were subjected to ultrasonic rinsing with MilliQ water for 10 min.…”

Degree of immobilization of synthetic RGDS(PO3H2)PA peptides on titanium surfaces

The purpose of this study was to characterize the chemical interaction between titanium surfaces and the peptide RGDS(PO3H2)PA (P-RGD) synthesized from RGD peptide (RGD) and o-phospho-L-serine (P-Ser), and to determine the degree of peptide immobilization on the titanium surface. X-ray photoelectron spectroscopy showed that the adsorption amount of RGD was significantly smaller than those of P-Ser and P-RGD (p<0.05). Furthermore, although it appeared that P-RGD bonded to the surface, ultrasonic rinsing with water caused it to dissociate, releasing RGD and leaving only S(PO3H2)PA bonded to the surface. These findings show that although it remains difficult to obtain a stable P-RGD layer, the phosphate functional group greatly improves immobilization of the molecule on titanium surfaces.
