The degree of HAp nucleation and nucleation development on the un-etched titanium plates was lower than that on the etched titanium plates. In vitro bioactivity of HAp-coated titanium testing using SBF solution showed prospective results.

The number of total hip arthroplasties (THAs) performed for patients undergoing dialysis is increasing. However, there are few reports of cementless THA for patients undergoing dialysis. This study investigated the midterm to long-term results of hydroxyapatite (HA)-coated cementless THA for dialysis patients. This single-center, retrospective study enrolled dialysis patients undergoing primary HA-coated cementless THA. A total of 24 patients (30 hips) were included in the fnal analyses.

The variance in clinical responses to polyetheretherketone (PEEK) cages with titanium (Ti) and hydroxyapatite (HA) coatings (PEEK-Ti-HA cages) is still not clear. In this study, we aimed to evaluate the radiographic and clinical outcomes of patients undergoing TLIF using PEEK-Ti-HA cages with a particular focus on fusion rate.

The efficacy of multi-ion doped nano-hydroxyapatite coated titanium intramedullary pins for long bone fracture repair in dogs was studied clinically. The present study was conducted on twenty-four dogs, accommodating six dogs in each group and were subjected to open reduction and internal immobilization with titanium intramedullary pins. Blood samples were collected on 0 day, at 3,6, and 9thweeks post operatively in all the groups to evaluate the levels of serum calcium, phosphorus and alkaline phosphatase.

In this study, we created a hydroxyapatite (HAp) coating layer on top of the Ti-6Al-4V substrate via sequent H2O2- oxidizing and RF-sputtering processes and determining the effect of H2O2-oxidizing state to the adhesion between HAp coating layer and Ti-6Al-4V substrate. The results showed that the H2O2-oxidized Ti-6Al-4V surface is rough and porous, which increases the adhesion strength of the HAp coating layer on the alloy substrate.

Porous biphasic calcium phosphate (BCP) ceramics exhibit good biocompatibility and bone conduction but are not inherently osteoinductive. To overcome this disadvantage, we coated conventional porous BCP ceramics with nano-hydroxyapatite (nHA). nHA was chosen as a coating material due to its high osteoinductive potential.

These methods have lengthy process and difficult to scale up, hence a simple method of nanofertilizer production amenable for large scale production and testing its applicability in crop production can help for upscaling this futuristic technology. With this background, research was undertaken to synthesize urea coated hydroxyapatite nanofertilizer for enhanced nitrogen use efficiency and its filed testing using aerobic rice as test crop.

To promote and enhance the biological responses of implant hydroxyapatite (HAP) coatings, these are modified by substitution with various ions for the development of bioactive bone implants. In the present work, we have fabricated a MgO/Tb,Eu-HAP dual substituted hydroxyapatite coating on borate passivated 316L stainless steel (316L SS) by the electrodeposition method.

Polyether-ether-ketone (PEEK) is increasingly being used for spinal applications. However, because of its biologically inactive nature, there are risks of false joint loosening and sinking. PEEK materials are coated with apatite to enhance the osteoconductive properties.

Zinc hydroxyapatite coatings (ZnHAp) were synthesized on 316L stainless steel by ion exchange method between hydroxyapatite coatings (HAp) and solution containing Zn(NO3)2. Effect of the initial concentration of Zn2+ and contact time to ion exchange process was studied. The analytical results of FTIR, SEM, Xray, and AAS showed that the obtained coatings were single phase crystals of HAp, and the present of Zn in HAp structure with the atomic ratios of Zn/Ca, (Ca + Zn)/P of 0.143 and 1.707 changed the morphology, the crystal diameter and the lattice parameters.

The present study demonstrated that TiN-coated implants showed less P. gingivalis surface adhesion and less bone resorption induced by P. gingivalis. In addition, the bone implant contact ratio of TiN-coated implants showed the highest percentage, with significant differences compared to machined, sandblasted, acid-etched, and radiofrequency magnetron sputter hydroxyapatite-coated surface modifications, even with P. gingivalis infection. This was the first report to demonstrate that TiN-coated implants were excellent for inducing osseointegration and inhibiting P.

Bone implant materials cause the most common complication of bone infections in orthopedic surgery, resulting in implant failure. Antibiotic treatment of bone infections leads to problems such as bacterial resistance and reduced osteogenic capacity.

The obtained results were compared to those of the conventional sintering process and also revealed that microwave processing was a promising method to fabricate PHS for tissue engineering application. On the other hand, nano-Ag, which was used as antibacterial effect to prevent infections, was successfully coated on the PHS by the electroless deposition process. The results showed that nano-Ag spots were homogeneously dispersed on the PHS.

The results show that the HAp/fCNTs nanocomposite coatings contain single phase of HAp and CNTs with the coating thickness of 6.9 µm and the amount of fCNTs in the coatings is 6.95 %. With the presence of fCNTs in HAp coatings, the solubility of the coatings decreases in comparision with pure HAp coatings.
