Chemically bonded biomaterial with tailored properties

Abstract:

A chemically bonded biomaterial element composed of an inorganic cement, exhibiting minimal dimensional changes upon hardening and long-time use, improved mechanical properties and improved translucency. An algorithm to describe the micro-structure is expressed as λ = d * ( 1 - V F ) ( V F ) where λ is the distance between filler particles of mean size d, and VF is the volume content of non-reacted cement and added filler, and where λ≦10 μm. The invention also relates to a device in connection with the preparation of a chemically bonded biomaterial element according to the invention.

Abstract(Chinese):

由无机水泥组成的化学键合的生物材料元素，在硬化和长时间使用时表现出最小的尺寸变化，改善的机械性能和改善的半透明度。描述微结构的算法表示为 $lambda=d*（1mo> -VF）（VF）其中lambda是平均尺寸d的填料颗粒之间的距离，VF是未反应的水泥和添加的填料的体积含量，并且其中λ<= 10um。本发明还涉及与根据本发明的化学结合的生物材料元件的制备有关的装置。Public/Granted literature US20060156959A1
