Technical Discussion: IPN De-bonding

Why do IPN teeth pop off the denture and what can be done?

By using interploymer-networking (IPN), manufacturers made teeth more wear resistant. Unfortunately, there are fewer molecular “spots” left to bond to the denture base. Older plastic teeth wear away quicker but rarely break off the denture base. IPN teeth don’t break away but they do have a de-bonding problem.

To overcome this problem, Armstrong Laboratory grinds diatoric holes in IPN teeth and applies a chemical agent to the underside of teeth to break down the IPN bond in that area.
