Abstract
A dental absorbent pad (10) is disclosed having a moisture permeable, outer layer (11), a moisture absorbent layer (12), a stiffening plate (13), and a moisture impermeable backing (14). The moisture absorbent layer and stiffening plate are smaller in size than the overlying outer layer and backing so that a margin (17) is formed thereby which surrounds the moisture absorbent layer and stiffening plate. The margin is very flexible and therefor comfortable to a patient undergoing a dental procedure.
Claims9
A dental absorbent pad comprising:
- a moisture permeable outer layer;
- a moisture absorbent layer positioned adjacent said moisture permeable outer layer;
- a stiffening plate positioned adjacent said moisture absorbent layer opposite said moisture permeable outer layer;
- and
- a backing layer positioned adjacent said stiffening plate opposite said moisture absorbent layer;
- said stiffening plate having a size and shape smaller than the size and shape of said moisture permeable outer layer and said backing layer to create a peripheral margin portion upon said moisture permeable outer layer and said backing layer;
- and
- said peripheral margin portion of said moisture permeable outer layer being bonded to said peripheral margin portion of said backing layer.
A dental absorbent pad comprising a flexible outer covering having a moisture permeable front layer and a back layer bonded to said front layer along a peripheral margin, said peripheral margin defining an internal cavity between said front layer and said back layer, and a core positioned within said cavity, said core having a moisture absorbent layer and a stiffening layer, whereby the stiffening layer provides rigidity to a middle portion of the pad while the peripheral margin remains flexible.
