Abstract
Different beta-whitlockite ceramic cylinders of standard size were implanted in the tibiae of rabbits to study the influence of micropores and chemistry on the biodegradation rate. The materials were evaluated by radiography and light microscopy. Surface chemistry was varied by the addition of impurities, while different applied pressures before sintering and different sintering temperatures gave rise to different micropores. Both factors influenced the biodegradation rate.
摘要
将不同标准尺寸的β-白磷钙石陶瓷圆柱体植入兔胫骨中，以研究微孔和化学成分对生物降解速率的影响。通过X射线照相术和光学显微镜对材料进行评估。通过添加杂质来改变表面化学性质，而烧结前不同的施加压力和不同的烧结温度会产生不同的微孔。这两个因素都会影响生物降解速率。
