Metal-on-metal bearings (MoM) have been reported to release metal ions that are potentially leading to adverse tissue reactions. Alternatively, ceramic-on-ceramic bearings (CoC) are an attractive treatment for young and active patients and composite materials like zirconia toughened alumina (ZTA) have been successfully introduced clinically. One of the most common ZTA-material in CoC is the Biolox® Within a clinical trial, three different patient groups were compared: a) a control group without any implants, b) patients, three months after unilateral treatment with Biolox® Introduction
