   VERNIS "LAQUE DENTAIRE". 



   ----------------------   1. FORMULE 54 - 4 54.    a.   SOUS-COUCHE.   Gomme Sandaraque   0.5   
Alcool Ethylique   50.0   acétone   49.5   b. VERNIS. Oxyde de Titane 1.5 
Gomme Sandaraque 9.5 
Acétate de Polyvinyle 4.0 alcool Ethylique 21.0 détone 64. 0 2. PREPARATION DU VEHNIS   "LAQUi.   DENTAIRE". a.   SOUS-COUCHE.   Laisser dissoudre   0.5   p. ue GOMME   SAN@ARAQUE   dans 50 p. d'ALCOOL   ETHYLIQUE   et   49.5   p.   D'AC@TT@N@   b. VERNIS. 1. Laisser dissoudre 9.5 p. de GOMME SHNSARAQUM dans 
21 p. d'ALCOOL ETHYLIQUE et 20 p.   d'ACETON@.   



   2. Ajouter à la solution 1. 1. 5 p. d'OXYDE DE   TIIAN2   et broyer le mélange jusqu'à l'obtention d'une suspension dont la grosseur des grains   d'OXYD   DE 
TITANE est de l'ordre de 2 à 3 microns. 



     3. Laisser   dissoudre 4 p. d'ACETATE DE POLYVINYLE dans 44p. d'ACETONE. 



   4. Ajouter la solution 3 à la suspension 2 tout en bien malaxant. 



  3. REMARQUES. a. Par VERNIS "LAQUE   DENTAIRE",   il faut entendre la préparation   liquide donnée par la formule 54 - 484 ; par"LAQUE DENTAIRE"   tout   court,   il faut entendre le   rébidu   qui reste adhérer aux dents après séohage spontané du vernis. b. En   vu*   d'améliorer les propriétés olfactives du VERNIS "LAQUE   DENTAIRE",  on peut y ajouter certaines essences ou substances odoriférantes condition qu'elles soient inoffensives et com-   pati@2bles   avec les autres constituants. o.

   La formule 54 - 484 est à considérer comme une formule type, mentionnée à titre d'exemple pratique ; elle n'est cependant   d'auoune   façon limitative, étant donné qu'il est parfaitement conoevable et possible soit d'utiliser d'autres matières pre- 

 <Desc/Clms Page number 2> 

 mières, qui seront décrites dans les REVENDICATIONS, soit de faire varier les teneurs des différents constituants - tre de larges limites, tout en conservant la propriété fon- damentale du VERNIS "LAQUE DENTAIRE" notamment l'ANCRAGE parfait aux dents vivantes. 



     Dans   cette ordre d'idées, on peut   p.ex.   faire varier la te- neur en OXYDE DE TITANE de 0 à 10 %, remplacer l'oxyde de titane par du KAOLIN, par de la SILICE ou des pigments simi-   ladres ;   ou combiner différents pigments en vue de préparer toute une gamme de vernis, de transparents à opaques, en passant par toutes les variétés intermédiaires, transluci- des et opalescentes. un conçoit également la préparation de toute la gamme en combinaison avec certaines matières colorantes ou avec des pigments coloriés et même avec certaines matières fluores- centes, ou encore avec des pigments à reflet métallique, p. ex. doré ou argenté. 



   Quant aux autres constituants, en particulier la GOMME SAN- 
DARASUE et l'ACETATE DE   POLYVINYLE,   on peut également faire varier leurs teneurs respectives tout en conservant la pro- priété d'ANCRAGE déjà mentionnée ; ces variations permet- tront d'agir sur le brillant, le dégré de dureté, la plasti- cité ou l'élasticité rémanente du LAQUE DENTAIRE. L'emploi de ces résines n'est d'ailleurs non plus limitative, étant donné qu'en incorporant au VERNIS "LAQUE DENTAIRE" des RESI- 
NES HYDROPHOBES appartenant à d'autres classes de résines naturelles, modifiées ou non, ou de résines synthétiques, décrites dans les REVENDICATIONS, on peut parfaitement con- stituer une formule équivalente.

   "DENTAL LACQUER" VARNISH.



   ---------------------- 1. FORM 54 - 4 54. a. UNDERCOAT. Sandarac gum 0.5
Ethyl alcohol 50.0 acetone 49.5 b. VARNISH. Titanium Oxide 1.5
Sandaraque gum 9.5
Polyvinyl Acetate 4.0 Ethyl alcohol 21.0 detonates 64. 0 2. PREPARATION OF VEHNIS "LAQUi. DENTAL". at. UNDERCOAT. Let dissolve 0.5 p. ue GOMME SAN @ ARAQUE in 50 p. ETHYL ALCOHOL and 49.5 p. D'AC @ TT @ N @ b. VARNISH. 1. Let dissolve 9.5 p. by GOMME SHNSARAQUM in
21 p. ETHYL ALCOHOL and 20 p. of ACETON @.



   2. Add to solution 1. 1. 5 p. TIIAN2 OXIDE and grind the mixture until a suspension is obtained with the grain size of DE OXYD.
TITANIUM is of the order of 2 to 3 microns.



     3. Let 4 p dissolve. of POLYVINYL ACETATE in 44p. of ACETONE.



   4. Add solution 3 to suspension 2 while mixing well.



  3. REMARKS. at. By VARNISH "DENTAL LACQUER", it is necessary to understand the liquid preparation given by the formula 54 - 484; Simply put, "DENTAL LACQUER" means the residue that remains adhering to the teeth after spontaneous drying of the varnish. b. In order to improve the olfactory properties of "DENTAL LACQUER" VARNISH, certain essences or odoriferous substances can be added to it, provided that they are inoffensive and compatible with the other constituents. o.

   Formula 54 - 484 is to be considered as a standard formula, mentioned as a practical example; however, it is not in any way limiting, given that it is perfectly suitable and possible either to use other raw materials.

 <Desc / Clms Page number 2>

 materials, which will be described in the CLAIMS, or to vary the contents of the different constituents - be wide limits, while retaining the fundamental property of the "DENTAL LACQUER" in particular the perfect ANCHORING to living teeth.



     In this connection, one can for example vary the content of TITANIUM OXIDE from 0 to 10%, replace the titanium oxide with KAOLIN, with SILICA or similar pigments; or combine different pigments to prepare a whole range of varnishes, from transparent to opaque, including all the intermediate, translucent and opalescent varieties. one also designs the preparation of the whole range in combination with certain coloring materials or with colored pigments and even with certain fluorescent materials, or again with pigments with a metallic reflection, eg. ex. gold or silver.



   As for the other constituents, in particular the GUM SAN-
DARASUE and POLYVINYL ACETATE, it is also possible to vary their respective contents while retaining the ANCHORING property already mentioned; these variations will make it possible to act on the gloss, the degree of hardness, the plasticity or the residual elasticity of the DENTAL LACQUER. The use of these resins is also not limiting, given that by incorporating into the VARNISH "LACQUER DENTAL" RESI-
HYDROPHOBIC NES belonging to other classes of natural resins, modified or not, or of synthetic resins, described in the CLAIMS, it is perfectly possible to constitute an equivalent formula.

** ATTENTION ** end of DESC field can contain start of CLMS **.

Claims

This patent claims the preparation, manufacture, sale and use of a varnish, called VARNISH "LACQUER DENTAI- RE ", pigmented or not, can be applied in two stages on the living teeth of the mouth, these two stages being the application of the UNDERCOAT on the one hand and the application of the VARNISH" DENTAL LACQUER " being obtained by the use, simultaneous or not, and the adequate mixture. <Desc / Clms Page number 3> at. one or more NATURAL HYDROPHOBIC RESINS; b. one or more HYDROFHOBIC SYNTHETIC THERMO- RESINS PLASTICS; vs. one or more suitable ORGANIC SOLVENTS, practically harmless to the human organism;

d. one or more PIGMENTS or COLORING MATERIALS OR CO- LORIEES non-toxic; and further exhibiting the fundamental properties a. to dry after a few minutes at mouth temperature; b. to adhere perfectly to the teeth, which amounts to saying that it must resist the action of saliva as well as the mechanical and chemical action of usual foods and drinks; vs. to be harmless to the human body both at the time of its application to the teeth and throughout the duration that the LA- THAT DENTAL "stays on the teeth.

5. APPLICATION OF DENTAL LACQUER ON THE LIVING TEETH OF THE MOUTH. at. It is of paramount importance that the teeth are perfectly brushed and cleaned with a good toothpaste; then the mouth will be rinsed well with water. b. Oven that the VARNISH provides a DENTAL LACQUER which adheres perfectly to the teeth, it will then be necessary to proceed to their adequate drying which will go hand in hand with the application of the SUB- LAYER.

The lips, lower and upper, are separated from the gum and the teeth using two cotton balls, or preferably a cellulosic material which does not defibrate; however, the saliva which wets the teeth is removed with the aid of a swab soaked in the liquid called UNDERLAYER. c. Using a suitable brush, soaked in the liquid called VER- NIS, we cover, in a single stroke, first the row of lower teeth, then the row of upper teeth d.

The superfluous varnish, which fills the interstices between the teeth or which covers part of the gum, is removed using a toothpick. e.Let dry for a few moments by inhaling through the nose and exhaling through the mouth. f. To finish rinse your mouth with cool water.
