VELASCO PENA, Marco Antonio  e  GARZON ALVARADO, Diego Alexander. Scaffolds implants for the bone regeneration.: Materials, techniques and modeling by means of reaction-diffusion systems. Rev Cubana Invest Bioméd [online]. 2010, vol.29, n.1. ISSN 0864-0300.

The aim of present paper is to review of biomaterial used in bone implants and its clinical applications and also to propose the hypothesis that a reaction-diffusion system may be used to regulate the porosity percentage, the pore size and their interconnection in injectable bone cement. In the first part are described the biomaterial in the bone tissue engineering, in the second one, are detailed the mechanical and geometric properties needed for the bone regeneration process, in the third one are explained the implant conformation and application methods, in the fourth one we made a review of computation modeling techniques applied to implant manufacture process and the bone regeneration process and finally, we propose the notion that a reaction-diffusion system may to serve to modulate the porosity of a injectable bone cement.

Palavras-chave : Scaffold; bone; bone cement; reaction-diffusion system.
