Which ceramic-tissue attachment attaches by chemical bonding with bone?

The correct option, bioactive fixation, refers to a specific type of interaction between ceramic materials and bone tissue that involves chemical bonding. This occurs when bioactive ceramics, such as hydroxyapatite, interact with the biological environment, leading to the formation of a chemical bond with the surrounding bone. This bond facilitates the integration of the implant into the bone, promoting osseointegration and improving the longevity and stability of the implant.

In contrast, morphological fixation refers to a mechanical interlocking of materials without a chemical bond, while biological fixation indicates a broader concept that may involve biological responses to materials but does not specifically denote the formation of strong chemical bonds with bone. Resorbable materials are designed to be gradually absorbed by the body and do not typically form lasting bonds with bone tissue. Thus, bioactive fixation stands out as the option that accurately describes the chemical bonding process with bone found in certain ceramic materials.
