초록 ▼

A disposable applicator tray, for topical application of fluoride gel and other dental medications, in the form of an arcuate mouthpiece having a U-shaped cross-section and comprised of flexible polymeric foam material. The interior channeled recess of the tray is anatomically contoured to fit respectively over either of the upper and lower teeth with the walls of the tray contacting the adjacent periodontal tissue. The flexibility of the tray provides a relatively snug seal between the tray perimeter and the peridontal tissue so as to prevent excessive loss of fluoride or other medication contained in the tray and the contamination and dilution thereof with saliva. The applicator tray, which can also serve as a protective mouthpiece for use during athletic activities, is vacuum formed in quantity from a sheet of inexpensive polymeric foam material, thereby permitting it to be economically disposed of after a single use. The bottom surface of the interior recess of the applicator tray, against which the biting edges of the teeth bear when the tray is inserted in the mouth, is provided with indentations anatomically configured to mate with the mouth\s dentition pattern and the walls of the tray are similarly anatomically configured so as to provide a comfortable, natural fit and a more thorough and extensive contact of the dental medication with the teeth surfaces.

대표청구항 ▼

In an applicator tray, for topical application of fluoride gel and other dental medications to the teeth, which is of the type comprising an arcuate mouthpiece with a channeled interior recess having a generally U-shaped cross-section and configured to fit oveR either of the upper and lower teeth of the mouth, the improvement wherein said tray consists essentially of a molded unitary element comprised of flexible, non-hydrotropic, fine-cell, cross-linked polyethylene foam material having a cell size in the range of 2-3 mils, a density in the range of 1.6-2.4 lbs/ft3, a water absorption factor of about 0.1% by volume in a 24-hour period, a tensile strength of about 40 psi and an elasticity, measured by percent elongation to fracture, of about 275, and the bottom and wall surfaces of the interior recess forming said U-shaped channel are anatomically configured at the time of molding of said tray with indentations adapted to mate in reverse impression with the mouth dentition pattern, whereby a comfortable, non-gagging fit of said tray inside the mouth is obtained with said bottom and wall surfaces of said tray being in close proximity to the tooth surfaces and the perimeter of the tray walls being flexed by the bite of the mouth to contact the adjacent periodontal tissue to thereby provide a snug seal therewith and prevent the contamination and dilution by saliva of medication contained in said tray.
