Ceramic materials based on lanthanum zirconate for the bone augmentation purposes: materials science approach

Abstract

The creation of new non-toxic materials that combines high osteointegration and strength characteristics is an urgent contemporary challenge. The use of complex oxides, such as lanthanum zirconate (La2Zr2O7), as non-reservable alloplastic implant materials is a novel and promising way of fulfilling this challenge. In this work, the ceramic materials based on undoped and alkali-earth (Ca, Sr) doped La2Zr2O7 were obtained. The main physical and chemical characteristics of the ceramic materials were determined. The effects of synthesis method and dopant nature on the target characteristics of potential allografts were established.
