For ceramics, which of the following pairings is incorrect?

The pairing regarding resorbable ceramics is incorrect because resorbable materials typically do not attach through a press-fit mechanism. Instead, resorbable ceramics are designed to degrade over time while allowing tissue ingrowth into their structure as they dissolve. This process promotes healing by enabling surrounding tissues to replace the material as it is resorbed.

In contrast, the other options accurately reflect the ways ceramics can achieve fixation. Morphological fixation involves the use of surface irregularities to encourage bone growth into the material, effectively cementing it in place. Biological fixation relies on the ingrowth of bone into the ceramic, resulting in a strong mechanical connection. Bioactive fixation entails a chemical bond forming directly between the bone and the material, allowing for integration and stability. Each of these mechanisms highlights the distinct ways ceramics can interact with biological tissues, while resorbable ceramics focus on a different trend where the material is gradually absorbed as tissue grows to fill the space.
