“…Vargas et al used variable thermal processing temperatures between 300-1500°C. The authors stated that at 500ºC there was ∼1 wt % and at 800ºC ∼0.14 wt % residual carbon [11]. In this study 850°C sintering temperature was used.…”

Different types of bone-graft substitutes have been developed and are in the market worldwide to eliminate the drawbacks of autogenous grafting. They vary in composition, strength, osteoinductive and osteoconductive properties, mechanism and rates by which they are resorbed and remodelled. Tooth derived hydroxyapatite (THA) is a novel biomaterial. This study was performed to determine the histological properties of THA on animals. A commercial coralline HA (CHA, Proosteon 200, Interpore Cross, USA) was used as control material. 20 sheeps were used and divided into 2 groups. Human THA (Group A) and CHA (Group B) materials were implanted to the tibiae of 10 sheeps for each group. The histological examinations of surrounding bone response were done 12 weeks after implantation. There was no significant difference histologically between group A and B. All materials were found to be surrounded by new bone tissue. THA was found to be as efficient as the standard CHA on histological basis. In addition, economical production of THA should be taken into consideration. Therefore, THA may be a viable alternative on bone grafting provided that clinical trials will be completed.

“…During its thermal dissociation, hydrogen migrates into the furnace atmosphere, while metallic Ti covers the container walls with a thin film. However, although the studied method constitutes an easy way to potentially increase the biocompatibility and osseointegration properties of AISI 316L Stainless Steel [4,5], further work would have to be carried out in order to address several related important issues that may arise. After being coated with Ti, the ceramic pieces can be better wetted by molten metals during the preparation of metal-matrix composites, or can be joined more easily with other ceramic or metallic materials.…”

Titanium Coatings on AISI 316L Stainless Steel Formed by Thermal Decomposition of TiH₂ in Vacuum

et al. 2009

Ti-coated AISI 316L stainless steel, for potential biomedical applications, is obtained by thermal decomposition of TiH 2 under vacuum. The presence of hydrogen in the coating material facilitates the sintering process of Ti particles, with simultaneous formation of several interdiffusion layers at the substrate/coating interface, whose thickness and chemical composition depend mainly on the treatment temperature. Coatings prepared at 1100ºC exhibit formation of a wide zone at the substrate/coating interface, which is associated with the appearance of cracks, and which consists of a mixture of λ + χ + α-Fe phases. Formation of abundant microporosity is also observed in this region, which is attributed to the Kinkerdall effect.

Abstract-Different types of bone-graft substitutes have been developed, and are on the market worldwide to eliminate the drawbacks of autogenous grafting. They vary in composition, strength, osteoinductive and osteoconductive properties, mechanism and rates at which they are resorbed and remodelled. Of these, THA is a novel material produced by one of us (FNO). This study was performed to determine the histological properties of THA on animals, and to achieve this a standard on the market coralline HA (CHA) was used as control. 20 sheep were used in this study and divided into 2 groups. Human THA (Group-A) and CHA (Group-B) materials were implanted to the tibiae of 10 sheep in each group. The histological examinations of surrounding bone response of the implant materials were done 12 weeks after implantation. There was no significant difference histologically between groups A and B. All materials were found to be surrounded by new bone tissue. THA was found to be as efficient as standard CHA on histological basis. In addition, economical production of THA should be taken into consideration. In future, THA may be a viable alternative on bone grafting when clinical trials were completed.
