The electron ray microanalysis (ESMA) showed an intimate bone-implant-compound already 4 weeks postoperatively. This compound was detectable in all sinter variants after 78 weeks. An area with changed material contrast was prepared on the surface of the implant with an extent of 45-55 micron until the 24th week and over 100 micron after 78 weeks. A surface stratum relatively rich in calcium and absolutely rich in phosphorus was formed in the immediate contact to the regenerated bone opposite to the implant nucleolus. This stratum had an approximate consistent extent of 20-35 micron from the 12th week. The relative intensity of the stratum rich in calcium and phosphorus corresponded to that of the bone around the implant. The stabilization of the reactive surface stratum can become assumed by that.
电子射线微分析（ESMA）显示，术后4周时骨-植入物复合物就已紧密结合。78周后，在所有烧结变体中都能检测到这种复合物。直到第24周，在植入物表面制备了一个材料对比度发生变化的区域，其范围为45-55微米，78周后超过100微米。在与植入物核仁相对的再生骨直接接触处形成了一个相对富含钙且绝对富含磷的表面层。从第12周起，该表面层的范围大致稳定在20-35微米。富含钙和磷的表面层的相对强度与植入物周围骨的相对强度相当。由此可以假定反应性表面层已稳定。
