pressure indicator paste
Also written as: PIP — Pressure Indicator Paste
A coloured diagnostic paste applied to the intaglio surface of a prosthesis to identify areas of excessive pressure or premature contact during fitting.
Full Definition
Pressure indicator paste (PIP) is a zinc oxide-based or silicone-based coloured paste used by dental clinicians and laboratory technicians to detect high-pressure contact zones on the fitting surface of dentures, occlusal splints, and other removable prostheses. When the prosthesis is seated, the paste displaces or thins at points of excessive pressure, revealing them visually. The technique guides selective relief adjustments to improve fit and patient comfort. In laboratory reports and clinical notes, editors should render this term in full on first use, followed by the abbreviation PIP. Do not confuse with 'articulating paper,' which records occlusal contacts, not tissue pressure.
Usage
Usage note: Abbreviate as PIP after first full use. Do not confuse with articulating paper, which assesses occlusal contacts, not mucosal pressure.
