Property comparison of various skull repair materials / 中国组织工程研究

ABSTRACT

Different materials for skull repair possess varying properties and clinical effects. Metal materials are the first to be applied, but most of them induce corrosion and heat conduction; Non-metal bone substitutes, such as organic glass, have ever been commonly used, but the poor biocompatibility and high infection rate of subcutaneous exudation limit their application; Bone cement shows good histocompatibility, but the repair scale is not complete; Medical silica gel is cheap and effective, but the appearance is not satisfactory resulting from local infections and material exposures; Titanium possesses good biocompatibility and well junctures with the skull, thus it is a promising materials although the shortages still remain. With the development of bioengineering research, the skull repair materials will open up concerning the study of bone tissue engineering, cartilage tissue engineering and cornea tissue engineering. This paper is aimed to search a well-biocompatible and clinically effective material for the skull repair by the comparison on the property and clinical application of varying materials.
