Problems solved by technology

However, the challenges posed by differences in oral geometry affecting mouthpiece configurations have not heretofore been overcome by providing different mechanical configurations or linkages that essentially attempt to adapt universal mouthpieces to different oral geometries

Embodiment Construction

[0010] attached figure 1 A conventional mouthpiece 10 for oral hygiene is shown. It comprises a housing part 12, which is generally rigid plastic. The housing portion 12 generally includes an upper tray 14 and a lower tray 16 that are separately configured to receive teeth in the user's upper and lower jaws. This mouthpiece is adapted to accommodate teeth in all upper and lower jaws, or utilize one tray to accommodate teeth in only one jaw, or to accommodate partial teeth in either or both jaws. However, for the following description, the mouthpiece will be described with upper and lower trays accommodating all of the user's teeth.

[0011] The bristle portion 18 is mounted on the upper and lower trays, and in operation it contacts the teeth for cleaning as the mouthpiece works. The bristle portion 18 comprises the usual bristle construction and bristle material (filaments). The mouthpiece 10 is driven by a drive unit 20 shown substantially at 20 . The drive unit 20 gener...

Abstract

A method and the resulting product for optimizing the configuration of a mouthpiece for cleaning teeth in which the configuration of the mouthpiece is optimized to the oral geometry of individual users. The method includes a first step (26) of producing a digital scan of the oral geometry of the individual user and then producing a rigid shell (30) for the mouthpiece substantially matching the digital scan. The configuration of the resulting mouthpiece is characterized by the outer surface of the shell not extending from the buccal surface of the individual teeth more than 7 mm (31 ); further, by the rear edge of the shell not contacting the tissues to the rear of the rearmost teeth (36), and still further by no more than a 2 mm overlap into the gum line (36), when the mouthpiece is operatively positioned in the user's mouth.

Description

technical field [0001] The present invention relates generally to oral tooth cleaning implements, and more particularly to mouthpieces, and more particularly to providing such mouthpieces configured to fit the particular oral geometry of an individual user. Background technique [0002] It is well known that each individual has a unique and specific oral geometry with its own specific features and dimensions. This wide variation in oral geometry presents some challenges to cleaning teeth with a manual or electric toothbrush, but also presents significant challenges to mouthware. In general, mouthpieces have advantages over toothbrushes in terms of cleaning efficacy and cleaning speed. However, the challenge of varying mouthpiece geometries affecting mouthpiece configurations has not heretofore been overcome by providing different mechanical configurations or linkages that essentially attempt to adapt a universal mouthpiece to different mouthpiece geometries. As a result, m...
