Macromolecular materials

Introduced: January 2000

Full Title

Full titles differ between systems:

IPC:

Materials for prostheses or for coating prostheses > Macromolecular materials

CPC:

Materials for prostheses or for coating prostheses (dental prostheses A61C13/00; shape or structure of prostheses A61F2/00; use of preparations for artificial teeth A61K6/80; artificial kidneys A61M1/14) > Macromolecular materials

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2000.
