“…One of the parameters that determine the final dissolution of calcium phosphate ceramics is the microporosity of the material during the immersion in the simulated body fluid. 21 More microporosity produced higher degree of dissolution of material. Thus, the reason why the TCP sheet sintered at 900, 1000, and 1100°C showed a higher dissolution rate may be attributed to more formation of microposity on the material surface as shown in Figure 4.…”

The purpose of this study was to investigate the influence of sintering temperature on in vivo and in vitro bioactivities of sintered tricalcium phosphate (TCP) sheets prepared by the tape casting technique. Green sheets of beta-TCP prepared by tape casting were sintered for 2 h in a furnace at atmospheric pressure, at five different sintering temperatures: 900, 1000, 1100, 1150, and 1200 degrees C. Measurement of X-ray diffraction and Fourier transform infrared spectrometry showed the presence of alpha-tricalcium phosphate phase in the TCP sheet sintered at 1200 degrees C, in addition to beta-TCP phase. As compared with the other sintered TCP sheet, the TCP sheet sintered at 1200 degrees C demonstrated a lower dissolution rate in phosphate buffered saline solution at 37 degrees C and pH 7.4 over 24 weeks, and more amount of apatite formation in Hanks' balanced salt solution with pH 7.4 was observed. After 4 weeks' implantation of sintered TCP sheets into tibial diaphyses of rabbits, the bone-sheet contact of the TCP sheet sintered at 1200 degrees C was significantly higher than that of the TCP sheet sintered at 900 degrees C. These results indicate that a flat sintered TCP sheet prepared by tape casting is a promising material for a bone substitute.

“…Some of the coating methods of the first approach include electrophoretic deposition (Ducheyne et al 1990), plasma spraying (De Groot et al 1990;Thull & Grant 2001), radio frequency or ionic ray sputtering (Cook et al 1988), laser ablation (Clèries 1999;Serra et al 2001) or hot isostatic pressure (Hero et al 1994). None of these methods produce covalent links with the substrate, and the majority are not cost-effective.…”

At present, strong requirements in orthopaedics are still to be met, both in bone and joint substitution and in the repair and regeneration of bone defects. In this framework, tremendous advances in the biomaterials field have been made in the last 50 years where materials intended for biomedical purposes have evolved through three different generations, namely first generation (bioinert materials), second generation (bioactive and biodegradable materials) and third generation (materials designed to stimulate specific responses at the molecular level). In this review, the evolution of different metals, ceramics and polymers most commonly used in orthopaedic applications is discussed, as well as the different approaches used to fulfil the challenges faced by this medical field.

“…Whereas the separation between the two structures is relatively difficult by SEM, the micro-Raman analysis allows a clear distinction between the crystals of hydroxyapatatite and tricalcium phosphate. Therefore, micro-Raman spectroscopy can be straightforwardly utilized to follow and develop deposition processes of thin films for medical applications [40,41].…”

The potential of Raman microspectroscopy as a powerful tool in characterizing solids will be demonstrated here with several applications on semiconductors and thin films. The method not only permits the identification of different localized microscopic regions, with a high spatial resolution and with no sample preparation, but also provides several basic information on the microstructure of solids.
