The SNOMED term specifies \"into jaw\" while the ICHI term \"Prosthetic dental implant\" inherently implies jaw as the target site, since dental implants are by definition placed into jawbone (alveolar bone of the mandible or maxilla).</td></tr><tr><td>372038002 (Advocacy)</td><td><a href=\"http://hl7.org/fhir/R5/codesystem-concept-map-relationship.html#equivalent\" title=\"equivalent\">is equivalent to</a></td><td>PZB.TA.ZZ (Advocating for a person)</td><td>PZB.TA.ZZ uses the TA (Advocacy) action on the whole-person target (PZB), representing generic advocacy on behalf of an individual without specifying a domain (self care, education, employment, etc.). This matches the scope of SNOMED's generic \"Advocacy\" concept, which similarly serves as an unqualified advocacy grouper.</td></tr><tr><td>448678005 (Application of ambulatory blood pressure monitor)</td><td><a href=\"http://hl7.org/fhir/R5/codesystem-concept-map-relationship.html#equivalent\" title=\"equivalent\">is equivalent to</a></td><td>ITA.AI.AH (Ambulatory blood pressure monitoring)</td><td>The ICHI code \"Ambulatory blood pressure monitoring\" directly corresponds to the SNOMED concept \"Application of ambulatory blood pressure monitor\" — both describe the same clinical intervention of applying a device to perform continuous/ambulatory blood pressure recording.
