Apparently a "liner" makes reference to a "dental liner". I found a definition. Still, I can't get the equivalent in Spanish.
A permanent soft liner is a layer of soft material that is fitted to the surface of a denture and rests next to the oral tissues. In short, a soft liner acts as a cushion or shock absorber between the hard acrylic base of a denture and the gums. Soft liners can be put in during the fabrication of new dentures or placed in exisiting dentures (permanent soft reline). |
