Definitions
- Prior testing methods have employed two plates of plastics denture material adhered together by a layer of denture adhesive composition, immersed in water at room temperature, and subject to mechanical testing.
- the apparatus comprises means for retaining the water-permeable polymeric membrane, in contact with the plate, under tension.
- the tension could be applied biaxially or, preferably, uniaxially.
- the device has first and second gripping means, preferably linear gripping means, on respective sides of the plate, for gripping the water-permeable polymeric membrane.
- one of the gripping means comprises, or is in contact with, tensioning means.
- the tensioning means preferably comprises a tensioning roller constructed to assuredly engage the polymeric membrane, for example aided by engagement teeth or spikes.
- each gripping means is linear, and longer than the corresponding extent of the plate. That is, when the plate is circular (as is preferred) the gripping means are longer than the diameter of the plate.
- the gripping means are preferably arranged centrally relative to the plate.
- the plaque is not part of the first aspect of the present invention.
- the plaque will be of a material believed suitable for use as a denture material. It will typically be an acrylic polymer material, especially PMMA.
- the denture adhesive composition is not part of the first aspect of the present invention. However it will be of a material believed suitable for securement of dentures. It will typically be a cellulose-derived polymer in combination with at least one further adhesive polymer, usually an alkylvinylether maleic anhydride copolymer or acid copolymer thereof, combined in a paraffinic base.
- the testing apparatus shown comprises a cuboid chamber 2. It has a horizontal bottom wall, four upstanding side walls and a horizontal top wall 4.
- the top wall 4 has a fill hole 6 and a circular PMMA plate 8 of diameter 7.5cm, drilled with 1mm diameter cylindrical perforations, about 28 in number across a diameter.
- the plate 8 is set firmly and sealingly into an opening in the top wall 4.
