Project objective

Research objectives and content The main objective is to improve the in vitro setting and hardening properties of a new biocompatible amorphous calcium phosphate bone cement with fast bone transformation rate and planning with time the in vivo experiments which are in fact very time consuming. Also, the analysis of the data takes time. In fact, these new biocompatible materials have to be characterised through the contract ERBFMB1CT961621. However, some natural delays have been produced in the development of this work due to the training and know-how transference between the IRC and myself. Also, delays have been produced in the development of some especial measurement equipments of fundamental importance to carried out up to the end the whole research project. It is known that amorphous materials dissolve faster under in vivo conditions and in growth of new bone may also take place faster. Our experience in the development and characterisation of a-Tricalcium Phosphate (a-TC based calcium phosphate bone cements, gained during my PhD Thesis, allows to foresee a good potential for these ideas. At present, the physiochemical mechanisms controlling the setting and hardening properties of these cements are well understood. Moreover, the stability and in vivo behaviour of these cements are correlated with these mechanisms. The resulting ideas suggest that it is possible to control the in vivo behaviour of this kind of cements by the modification of some control factors affecting the powder phase, the liquid phase or the mixture. These seems to be a good possibility to modify the rate of resorption of these cements as well as the rate of new bone formation by adding some additives to the original a-TCP powder. From a previous study we know that one of these additives produces amorphous calcium phosphate cements. it will be important to study the resorption rates of the new formulations in vitro and in vivo as well as the osteoclastic and osteoblastic answers of the bone tissue around the implant. Training content (objective, benefit and expected impact) It should be pointed out that the possibility to use a wide range of very sophisticated techniques all of them available in the same centre will be of enormous interest. The possibility to perform cell culture tests as a biological feed-back for the physical and chemical development of the cement has a paramount relevance. It will be possible to optimise the product from all the important points of vue at the same time. The benefits will not only be personal, but the whole research group in Barcelona will profit of such training at my return. A great impact of to project is expected since the development of amorphous fast resorbable bone cements with a great capacity stimulating bone apposition is a goal that may be of enormous interest in traumatology, odontology and orthopaedics.
