Claims4
A process of cleaning an oral appliance comprising the steps of:
- providing a cleaning composition concentrate comprising, in weight percent,
- water in an amount of about 49.38%;
- citric acid in an amount of about 12.5%;
- potassium hydroxide 45 weight % concentration in the amount of about 22.7%;
- ethoxylated fatty alcohol surfactant in an amount of about 0.17%;
- N-alkyl C12-C18 dimethyl benzyl ammonium chloride in the amount of about 10.25%;
- tetrasodium ethylenediaminetetraacetate in the amount of about 5.0%;
- diluting the cleaning composition concentrate with water to a concentration of between about 1:25 to about 1:125, thereby providing a working solution;
- exposing a surface of the oral appliance to the working solution;
- subsequently exposing the surface of the oral appliance to an anti-microbial coating solution comprising a quaternary ammonium organosilane according to the structure of:
- Wherein:
- R is an alkyl group, of C1-C4;
- R1 is an alkyl group of C1-C8;
- R2 is an alkyl group of C1-C8;
- R3 is an alkyl group of C11-C22;
- and
- X is the counter ion of Cl− or Br−
- wherein, the treated oral appliance has a sanitized surface, the sanitized surface has the anti-microbial coating comprising the quaternary ammonium organosilane.

- supplying a film coating composition concentrate comprising a quaternary ammonium organosilane according to the, structure of:
- wherein:
- R is an alkyl group, of C1-C4;
- R1 is an alkyl group of C1-C8;
- R2 is an alkyl group of C1-C8;
- R3 is an alkyl group of C11-C22;
- and
- X is the counter ion of Cl− or Br−;
- wherein the film coating composition concentrate comprises in weight percent:
- water in an amount of about 48.38%;
- citric acid in an amount of about 12.50%;
- potassium hydroxide 45 weight % concentration in an amount of about 22.78%;
- ethoxylated fatty alcohol surfactant in an amount of about 0.17%;
- N—N-alkyl C12-C18 dimethyl benzyl ammonium chloride in amount of about 10.25%;
- tetrasodium ethylenediaminetetraacetate in the amount of about 5%;
- and
- 3-(trimethoxysillyl) propyldimethylocatedcyl ammonium chloride;
- diluting the film coating composition concentrate with water to about 1:25 to about 1:125;
- and applying the diluted film coating composition concentrate to the surface of an oral appliance thereby providing an antibacterial coating to the surface of the oral appliance.
