Description:
SUMMARY OF THE INVENTION 
     This invention relates to a novel dental floss holder customized for use by an individual user. The invention may be adapted to be used to floss all of the user&#39;s teeth at one time, or may be provided in one or more sections adapted to floss only specific teeth of the user. 
     A primary object of this invention is to provide a dental floss holder adapted to position one or more lengths of floss in proper relative relationship between individual teeth of the user for whom the floss holder is customized. 
     Another primary object of this invention is to provide one, or more, floss holders customized to guide floss between a plurality of selected teeth of the user. 
     A third object of the invention is to design a floss holder easy to load with floss and which can be easily cleaned and in which the floss can be replaced easily and simply. 
     A fourth primary object of the invention is to provide impression means to customize the floss holder to fit the floss between the teeth of the intended user. 
     A fifth primary object of the invention is to provide fastening means to keep the floss in tension when inserted between the user&#39;s teeth during flossing. 
     A sixth object is to provide a floss dispenser. 
     These objects and advantages, and others, will be illustrated and set forth in the drawings and the detailed description to follow.

     DETAILED DESCRIPTION 
     Reference to FIG. 1 shows a drawing of a first form of the invention which includes a body portion 10 in the form of a dental floss holder 12 comprising an optional handle 14. The body portion 10 may have an H shaped cross section 16. The upper part 18 of the H shaped cross section 16 comprises a U shaped cross section 18a and the lower part 20 comprises an inverted U shaped cross section 20a. In other forms of the invention the upper parts 18a and the lower parts 20a may be formed seperately for upper and lower teeth of a user as indicated by the dotted line 22 in FIG. 2. 
     The word &#34;floss&#34; as used herein includes any thread or similar material for floss type tooth cleaning. The term &#34;impression material&#34; as used herein includes material which can be used by the dental profession for making casts. 
     FIG. 3 is a cross section of a form of the invention for use only on the upper teeth. The bottom 22a defines the lower side of its U shape. The cross sectional construction of this FIG. 3 form is somewhat enlarged to show clearly the method of construction of the invention for all forms and the methods of use and the preferred construction of these forms. 
     There is at least one layer of impression material 24 to form at least one impression mold area 26 which will be defined by the teeth 27 and gums 34 of the particular individual for whom a form of the invention is crafted. Side walls 28 include floss guides 30 to position the floss 32 properly between the teeth of the person who uses the invention. The flosser 12 is completed for a particular individual by loading the impression mold area 26 with impression material 24 well known in the art. Impression mold materials used in the dental arts may be used. The mold containing the impression material is placed in the user&#39;s mouth in the usual manner and the user bites into the impression material, keeping the jaws tight until impression material sets. 
     After the impression material sets to the desired consistency the next step is to remove the impression from the user&#39;s jaw. The next step is to form floss guides 30, preferably V shaped. The floss guides 30, when properly located and cut out, will guide floss 32 between the user&#39;s teeth with the apex of the floss guide 30 guiding the floss 32 to the optimal depth (or height) in the flosser 12 to position the floss 32 properly to floss up to and slightly beyond the the gum line without cutting into and injuring the gum 34 of the user. The dental technician can easily determine the proper depth by examining the line where the gum 34 ends in the set impression material 24. This will prevent the floss 32 from positioning too deeply and possibly injuring the gum 34. 
     The next step is to remove the excess impression material 24 located between opposed floss guides 30 down to a line (indicated by reference numeral 25) leaving impressions 36 of the biting or chewing ends of the teeth 27 in mold area 26. 
     The floss 32, when loaded into the floss guides 30, may be secured by floss fastening means such as cleat formations 38. 
     The device, when completed for the intended individual, is used by inserting the desired size and configuration of floss holder 12 at the proper position of the user&#39;s mouth for which it is designed. 
     The user then clenches his, or her, jaws causing the floss 32 loaded in the floss guides 30 to be inserted between the user&#39;s teeth. To faciliate the insertion of the floss 32 the user can move the lower jaw from side to side and front to back while clenching the jaws. Holding the handle 14, the user can pull the flosser 12 forward, pressing the floss 32 against the back surfaces of the side teeth and at the same time moving the lower jaw up and down. This will cause the dental floss 32 to scrape the back surfaces of the side teeth. By repeating the same proceedure, except that the user pushes the floss holder 12 backwards, the front surfaces of the side teeth are flossed. 
     To floss the side surfaces of the front teeth, the user first presses the floss holder 12 to one side (for example, the right side) and moves the lower jaw up and down to floss the left side of the front teeth. Then the user presses the floss holder 12 to the left side to floss the right surfaces of the front teeth. 
     The above descriptions illustrate the preferred forms of my invention, and I do not wish to be limited by them, but desire to be protected for all forms coming within the claims set forth below.
