Estudio de la capacidad de regeneración ósea de implantes microporosos de Titanio procesados mediante Robocasting

Abstract

Bone regeneration is a concept applied to a wide range of fields in medicine with the main objective of achieving or increasing bone regeneration. Multiple techniques have been described due to the significant limitations and complications that exist with current clinical treatments. The development of this field has been continuous in recent years together with the development of different type of materials. Polymers and ceramics showed a poor rate of resistance to the physiological loads to which the bones are routinely subjected. Alternatively, metal structures are attractive due to their mechanical strength and the ability to resist fatigue over long periods of time. Nowadays, titanium is the material of choice for multiple orthopedic processes due to its excellent mechanical properties and its high biocompatibility. Recently, based on compact titanium implants, titanium porous metals have begun to be developed. Complex three-dimensional metal structures are currently being manufactured using different additive techniques. Robocasting is an additive technique in which a filament of ink through a nozzle forms the object layer by layer. In this technique a model with 3D computer-aided design is divided into layers, a fluid is extruded through a small nozzle, giving the shape of the previous model...
