“…Diffraction maxima corresponding to the hexagonal crystalline structure of hydroxyapatite were identified at 2θ values of 26.4 • , 28.7 • , 29.4 • , 32.2 • , 33.9 • , 34.1, 35.6 • , 39.9 • , 47.6 • , 49.9 • , and 53.6 • . The corresponding diffraction planes are evidenced in Figure 1.The intense doublet, attributed to the presence of (211) and (112) planes, confirmed the synthesis of stoichiometric crystalline HAp[72], according to the JCPDS09-0432 file and previous results from the literature[73,74].The presence of large, overlapped reflection peaks indicated the reduced crystallinity of the synthesized material, a result expected due to the absence of additional thermal treatments[75,76]. However, the formation of high purity HAp powder was confirmed, as no secondary phases were noticed.The SEM measurements (Figure2) showed the presence of HAp aggregates, consisting in needle-like nanosized individual particles (width of ~10 nm, length between 10−100 nm).…”

Osteoconductive and osteoinductive coatings represent attractive and tunable strategies towards the enhanced biomechanics and osseointegration of metallic implants, providing accurate local modulation of bone-to-implant interface. Composite materials based on polylactide (PLA) and hydroxyapatite (HAp) are proved beneficial substrates for the modulation of bone cells’ development, being suitable mechanical supports for the repair and regeneration of bone tissue. Moreover, the addition of osteogenic proteins represents the next step towards the fabrication of advanced biomaterials for hard tissue engineering applications, as their regulatory mechanisms beneficially contribute to the new bone formation. In this respect, laser-processed composites, based on PLA, Hap, and bone morphogenetic protein 4(BMP4), are herein proposed as bioactive coatings for metallic implants. The nanostructured coatings proved superior ability to promote the adhesion, viability, and proliferation of osteoprogenitor cells, without affecting their normal development and further sustaining the osteogenic differentiation of the cells. Our results are complementary to previous studies regarding the successful use of chemically BMP-modified biomaterials in orthopedic and orthodontic applications.

The precipitation method successfully synthesized cockle shells into a highly valuable biomaterial in the present investigation. The present work aimed to determine the effect of the technical approach; (1) calcination temperatures of calcium oxide preparation and (2) sintering time of HA synthesis. Thermogravimetric-differential thermal analysis revealed that the cockle shells were calcined at 600 – 1000 °C for 3 hours and had a fine CaO powder. Thus, those sintering temperature is used as the starting point for the calcination of cockle shells. The calcinated CaO powder was then analyzed. The analysis conducted includes yield, functional group analysis using FT-IR, morphological analysis using SEM, and analysis of the composition of Carbon (C), Calcium (Ca), Oxygen (O), and Phosphor (P). Furthermore, hydroxyapatite synthesis (HA) was done with three different sintering times (2, 4, and 6 hours) at 800 °C. The characterized HA was functional group morphology, major elemental in the apatite constituents, and the crystallinity degree. Obtained the optimum temperature result for calcinated at a temperature of 800 °C. The results of HA synthesis obtained by HA quality have approached commercial HA products judging from the composition of Ca, O, and P, but the quality still includes type B of commercial HA. The HA particles obtained are micro-sized, which is 304 nm at a temperature sintering of 800 °C for 4 hours. The micro-sized allows a by-product of cockle shells as raw material HA to be applied as a futuristic biomaterial in bone/teeth implants.

“…8a, the synthesized CHA is mainly composed of spherical particles with a large amount of agglomeration since the mechanochemically prepared materials usually show high agglomeration [18]. It is important to note that the presence of this agglomeration in the synthesized apatite sample is bene cial, according to the literature, as it allows the circulation of body uids when this sample is applied as a coating on the implant [59]. The elemental analysis of the prepared CHA, as shown in Fig.…”

The aim of this work is to prepare nanocomposites with excellent bioactivity and appropriate mechanical properties. In this regard, the nanocomposites, with different contents of borosilicate glass (BG) and carbonated hydroxyapatite (CHA), were mixed and milled using a high-energy ball mill. Then, these milled powders were subjected to sintering at 750 ºC. In order to examine their phase composition, molecular structure and microstructure, X-ray diffraction (XRD) technique, Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM), respectively were used. Moreover, the DC electrical conductivity, and physical and mechanical properties of the prepared nanocomposites were also measured. In addition, the in vitro bioactivity of the sintered samples was evaluated using XRD and SEM. Unexpectedly; the results indicated that the successive increase in BG contents promoted the partial decomposition of CHA molecules at this lower sintering temperature. Also, it was responsible for the enhanced bioactivity behavior along with giving CHA better mechanical properties. However, the electrical conductivity of the examined samples exhibited an opposite trend where it decreased signi cantly with increasing BG content. According to the results obtained, the prepared samples are suitable for use in various biomedical applications.
