Scalloped dental trays for use in treating teeth with sticky dental compositions
DCFirst Claim
1. A scalloped dental tray configured to hold therein a quantity of a dental composition for carrying out a desired treatment of a person'"'"'s teeth, the dental tray comprising:
- a periphery that has been scalloped so as to be trimmed in such a way that the dental tray substantially covers the person'"'"'s teeth while not overlapping the person'"'"'s gingival margin and interdental papilla when the dental tray is placed over the person'"'"'s teeth during the desired treatment; and
a main dental tray portion which extends below said periphery and which is configured to hold therein a desired quantity of the dental composition.

Abstract
The present invention discloses high viscosity sustained release dental compositions, such as tooth bleaching or fluoride compositions, for treating tooth surfaces. For maximum results, an improved dental tray having reservoirs for holding the dental composition adjacent the desired tooth surfaces is preferably used in combination with the sustained release dental composition. The sustained release dental compositions include a high carboxypolymethylene concentration which results in very high viscosity. The high level of carboxypolymethylene makes dilution of the dental compositions from saliva difficult and time consuming so that the compositions stay within the tray reservoirs, thereby providing sustained release. The concentrated carboxypolymethylene adds a unique tackiness to the dental composition which helps retain and seal the soft tray material against the patient'"'"'s teeth.

9. A thin, flexible scalloped dental tray configured to hold therein a quantity of a dental composition for carrying out a desired treatment of a person'"'"'s teeth, the dental tray being formed from a single layer of a polymer sheet material and comprising:
-
a periphery that has been scalloped so as to be trimmed in such a way that when placed over the person'"'"'s teeth the dental tray covers the person'"'"'s teeth up to within about ¼
mm to about ⅓
mm of the gingival margin on at least the buccal surface of the person'"'"'s teeth but so that the dental tray does not cover the interdental papilla; and
a thin, flexible portion which extends below said periphery and which is configured to hold therein a desired quantity of the dental composition. - View Dependent Claims (10)
