CLOSED SYSTEM MOUTHPIECE WITH LIGHT AND HEAT GENERATION TO ACTIVATE A FORMULATION TO INCREASE ITS VOLUME

Номер: US20150037749A1
Автор: Dave Elmar A., Levine Jonathan B., Murray Owen J.
Принадлежит: JBL Radical Innovations, LLC

A closed system mouthpiece uses light and heat generation to activate a gel formulation to increase its volume. The gel formulation is coated into the mouthpiece, which is inserted into the user's mouth. Application of heat above a threshold temperature causes the gel to transform into foam and expand out of the mouthpiece and into the oral cavity. The mouthpiece creates a hermetic seal such that the foam expands out throughout the oral cavity into nooks and crannies that are normally difficult to access. Activation of a light source embedded within the mouthpiece enhances the bacteria killing properties of the foam material. The pH balance of the mouth is restored by the inventive method and apparatus to a neutral level in the range of 6.75 to 7.25. 1. A mouthpiece , comprising:a) a main body having a bite tab extending rearwardly central of said main body and having upper and lower surfaces engageable by a user's teeth;b) said main body having a periphery extending above and below said bite tab and including a peripheral seal extending therearound and engaging gums of a user wearing said mouthpiece to seal a user's oral cavity from outside said oral cavity;c) said mouthpiece carrying a pH sensor immersable in saliva within the oral cavity and generating signals indicative of pH of saliva; andd) an indicator operating responsive to generation of said signals to display pH of saliva within said oral cavity.2.

A disposable, inflatable, matrix (tooth dam) used to form a temporary, removeable side wall for the placement of a tooth filling material. It establishes the original dental anatomy of the tooth, and maintains the correct contact between adjacent teeth for flossing purposes and gingival health. It accomplishes this by inflating a pair of self-sealing air chambers that extend from the back face of a planar panel that they are formed on, such that these chambers contact and press against the adjacent tooth and exert enough force to elastically secure the planar panel without wedges and clamps. It prevents the tooth filling material from leaving the prepared tooth and entering the space between the teeth to enhance flossing and proper dental hygiene. This device will greatly enhance patient comfort, procedural efficiency and consistency

The distal air chamber has a volume that equals or exceeds the combined volume of the central and proximal air chambers. Directly below the distal concavity on the inner face of the planar substrate is an adhesive region. When the distal air chamber is depressed, the air within inflates the other air chambers and it is retained in its compressed state by the adhesive region. The remaining air chambers press against one tooth and exert enough force to elastically secure the planar panel around the adjacent tooth. It prevents the tooth filling material from leaving the prepared tooth and entering the space between.

System and methodology objectively capture clinical data on oral health and provide standardized scoring for quantifying oral health. The process of capturing clinical data is based on use of an intraoral camera with imaging software that has the capacity to capture digital images of all tooth surfaces. Digital plaque data are collected in a standardized manner per tooth, and with the ability to select optimal frames for analysis. Data are extracted per tooth into a software program. Color classification of each pixel is determined by the software program using an algorithm that makes use of red/green/blue color code combinations. These classifications are then quantitatively used within the software program and separate algorithms that automatically generate a range of oral health scoring techniques. 1. A method of assessing oral health in a patient or subject , comprising the steps of:providing an intraoral camera that can capture or record frames within a mouth of said subject;using the intraoral camera, capturing or recording the frames of substantially all buccal, occlusal, and lingual surfaces in the subject's set of teeth;importing the frames into an image processing software program implemented on a computing device;processing the frames on the image processing software program to generate images of the teeth to be analyzed;analyzing and classifying color of at least a plurality of the frames to determine presence of yellow color, wherein the yellow color indicates presence of plaque;scoring results of the color analysis to objectively and quantitatively assess the oral health of the subject.2.
