ARTICLE AND METHOD FOR FORMING A DENTURE Filed May 2, 1967 I 2 Sheets-Sheet 2 ATTORNEY United States Patent Int. Cl. A61c 9/00 US. Cl. 32-2 12 Claims ABSTRACT OF THE DISCLOSURE An article and method for forming a denture including a pro-formed tray having a set of teeth therein. A moldable resin is poured into the tray having a set of false teeth therein, and the tray is placed into an envelope.
The user places the envelope into his mouth and by applying pressure to the resin through the envelope, a final denture is formed.
The art of making dentures for individuals who require false teeth has been carried on for many years. The process requires many hours of tedious work by a skilled technician in order to make a denture which is tailored to an individualsmouth. The-time elapsed between the first visit to a dentist and the fitting of a finished denture is on the average four to six weeks.
Initially the individual must see a dentist who places an alginate gel or similar moldable plastic in a metal tray from which an impression is made of thepatients gums and roof of the mouth or palate if an upper denture is required. The impression is sent to a dental technician who makes a plaster cast of the gums and palate and places the cast in an articulator. A wax base plate is poured on and false teeth are positioned in the wax. The wax denture is returned to the dentist who trys it on the patient. The dentist makes corrections and returns the trial denture to the technician. The technician then begins the long laborious task of making a denture which requires many steps well known in the art and takes many hours and requires expensive, specialized tools.
The technician uses plaster of paris and resins which tend to stick together, and the plaster must be carefully cleaned from between the false teeth or they can be scratched. The finished mold must be sanded and polished and a great deal of dust is produced in the laboratory creating a very unsatisfactory environment.
Our invention dispenses with the use of plaster as a molding material and the inherent difiiculties concomitant therewith. For example, the process of mixing the plaster solution, pouring, fiasking and heating are eliminated enitrely including the arduous task. of removing the plaster from the finished denture which can ruin an otherwise completed denture if one is not careful.
The present invention seeks to overcome the obvious expensive and arduous task of making. a denture and to dispense if desired with the services of a dentist and technician. Any unskilled person can make a satisfactory denture by utilizing the principles of our invention. Basically, our invention contemplates using a moldable resin which is poured into an adjustable and flexible tray having false teeth placed therein and formed to fit into an average size mouth. The tray containing the resin is placed in an envelope. The user places the envelope containing the tray in his'mouth and by exerting oral muscular pressure upon the resinous mass, a denture is formed which is identical to the contour of the gums and palate. The latter procedure requires approximately two hours including curing time as compared with fifteen hours including curing time by a skilled technician and "ice not including time lost by sending the denture between the technician and dentist for adjustment.
It is an object of this invention to enable an unskilled person to form his own dentures and more specifically to form a denture requiring few steps.
It is a further object of this invention to provide a tray which is adjustable to fit a persons mouth.
It is still a further object of this invention to utilize materials which are compatible and do not stick together.
It is another object of this inventionto enable a person to make a denture that will require little time to fabricate.
It is still another object of this invention to enable a denture to be made without using plaster as an element in the mold. a
It is still a further object to provide a method for forming a denture in which the oral tissue does not contact any injurious substance used in making the denture.
It is yet another object of this invention to maintain teeth properly spaced and held together in a tray by using a silicone rubber or other suitable binder.
It is an additional object of this invention to provide an envelope which permits harmful vapors to escape from the oral cavity and precludes the oral tissues from coming into contact with the resin or vapors.
It is still another object of this invention to provide a method for making a denture which requires few parts and is simple to fabricate and inexpensive to manufacture.
Additional objects will become apparent to those skilled in the art from reading the ensuing specification, drawing and claims in which we have disclosed a preferred embodiment of our invention.
The attached drawings illustrate a preferred embodiment of our invention in which:

FIG. 7 is a top view of a tray having resin therein and a cutaway showing false teeth embedded in said resin;
FIG. 8 is a view taken along the line 88 in FIG. 7;
FIG. 9 is a perspective showing a tray in an envelope.
FIG. 10 is a view taken along the line 1010 in FIG. 9;
FIG. 11 is a top view of a finished denture within a tray;
FIG. 12 is a view taken along line 12-12 in FIG. 11, and
FIG. 13 is a side elevation partly in section showing false teeth molded within a denture which has cured.
Referring to FIGS. l-4, there is shown a tray 20 which is preferably formed of a thin flexible plastic in the family of polyethylene or polypropylene polymers or co polymers. The tray can be vacuum formed from a sheet of material. The tray could also be formed by any other known method such as injection or blow molding. The tray 20 is used for making an upper denture and the tray 22 is used for making a lower denture.
Reference will now only be made to the upper tray 20 and since the tray 22 is similar like parts will be referred to with like numbers.
The tray 20 has weakened lines 24 conveniently placed thereon preferably in the form of triangular lines; however, any configuration can be used. The weakened lines are to be severed which permits the tray to be modified in size. Thus, the tray can be adapted to any size month by cutting the weakened lines and squeezing or spreading the tray.
An adhesive tape 26 can be used to lock the severed por-.
tions together when the proper size has been made to fit the mouth of the particular user, or if a portion is removed to make the tray smaller, the tape can be used to fill the void. The weakened lines 24 are preferably placed in the palate portion 28 on the upper tray 20. The palate portion 28 is shaped to conform to the average persons mouth and by simple adjusting after the weakened lines have been severed will fit any mouth. The weakened lines 24 are placed on the inner wall on the lower tray 22.
The upper tray 20 has an outer flexible wall 32 which is generally U-shaped. The palate portion includes an inner flexible wall 31. The inner and outer wall portions are interconnected along the U-shaped bottom portion of the tray.
The lower tray 22 also includes a flexible outer wall 32 and a flexible inner wall 31 which walls are interconnected along the U-shaped bottom portion of the tray.
The gum-receiving portion 30 which lies between the outer and inner walls 31 and 32 comprises a trough 34 which is designed to receive false teeth 42 and a persons gums. The trough 34 is relatively narrow at the forward portion 36 of the tray and gradually increases in width along the side portions 38 of the tray as shown in FIG. 5. Thus, the front teeth which are relatively narrow are snugly held in the tray and the rear teeth which are wider are snugly held in the wider portion of the tray.
Impressed within the trough 34 of the tray 20, as by molding or any other suitable method of indicating, is indicia or cavities in the form of spaced depressed portions 40. The latter indicia 40 indicates to the user the proper placement of the false teeth 42 within the tray 20 prior to making the denture. Each tooth is thus snugly held within a depression and because the trough 34 increases gradually in width, the teeth 42 are supported and cannot readily move out of place. Thus there can be no leaning or turning movement of the teeth and perfect alignment is always insured.
The false teeth 42 are firmly and immovably held within the tray preferably with a rubber 44 of the silicone type to which a catalyst such as dibutyl tin dilaurate has been added. Any other binder material can be used to hold the false teeth together in the mold such as rubber of the nonsilicone type, glue, wax or a mechanical means such as a brace can hold the teeth together. The purpose of the silicone rubber 44 or other type binder is to hold the teeth within the tray in proper spaced relation to each other and to avoid coverage by the denture of the teeth resin that would result in an extra cleaning step. Actually a denture can be made without the binder.
When the silicone rubber mix and catalyst are used, the mix is poured or injected into the trough 34 of the trays 20 and 22. The false teeth 42 are then placed into the mix as indicated by the indicia 40 on the walls, and the rubber 40 is allowed to cure whereupon the teeth will be immovably held in the tray. The rubber 44 will not adhere to the tray or false teeth firmly and is easily separated therefrom after the denture has been completed because of the nature of the materials.
The silicone rubber 44 or other binder could be dispensed with by molding pockets or depressions within the tray which firmly grips and maintains the teeth closely adjacent to each other during the molding process. The tray is now ready to receive the denture material 46.
The denture material 46 is a cold curing pigmented mixture consisting of a powder and a liquid. The powder is a polymer preferably of the acrylic family. Certain copolymers can also be used consisting of vinyl resins or styrene. The liquid material is preferably an acrylic monomer or mixture of acrylic monomers such as methyl methacrylate and butyl methacrylate. These materials have been used in the prior art as denture repair materials. The powder and liquid contain small quantities of known catalysts which interact to cause hardening of the mixture within a short time without any external heat source.
The powder and liquid are thoroughly mixed together to form a soft, puttylike, resinous slurry which is poured into the denture forming tray 20. If desired, a shim 48 can be loosely attached to the upper tray in order to control the thickness of the palate portion 28 of the denture which is preferably between 1 to 3 millimeters in thickness. The denture can be made without the shim, however. The resin mixture covers the false teeth up to the binder 44 and the entire interior of the tray 20 circumscribed by the outer wall 32. i
Since the gum tissue is sensitive to the resin 46 the resin filled tray is preferably covered with a thin flexible material such as plastic or cloth having a low permeability to the monomer of the denture material. The protective covering can be placed over the gums and palate in the users mouth or can cover the resinous material in the upper and lower tray 20. A preferred protective covering is a material comprising a polyvinylidene chloride film in the form of an envelope 50 as depicted in FIG. 9. Three sides of the envelope are sealed and one side 52 is open. The tray 20 is inserted into the envelope 50 with the front portion of the tray 20 facing the open end 52 of the envelope to allow vapors to escape outside the mouth cavity while the opposite closed end prevents vapors from entering the mouth cavity.
The tray 20 and envelope 50 unit, generally denoted by numeral 54 is then placed in the mouth so that the gums are placed within the confines of the walls 32 of the tray 20. The user then exerts pressure on the unit 54 by biting into the resinous mass and pressing against the palate portion 28 of the tray with the tongue. A pad 56 shown in dotted lines in FIG. 12 may be inserted between the tongue and the palate portion 28 of the upper tray in order to obtain a better forming pressure transfered to the resinous denture material. The pad 56 can be a foam rectangular or square cube. The unit 54 is kept in the month until the resin mixture feels warm to the senses which entails approximately fifteen (15) minutes. The unit 54 is then carefully removed from the mouth by releasing the previously applied pressure. The denture material has now been molded to precisely the shape of the gums and follows the curvature of the roof of the mouth for the upper denture. The resinous mass is allowed to cure for an additional time of approximately ten to fifteen minutes. The upper and lower dentures can be made at the same time or separately.
The user, thereupon, removes the upper or lower tray 20 or 22 from the envelope 50. The tray because it is flexible is merely bent away from the curved denture and the resin does not adhere to the flexible tray. The rubber 44 is easily peeled away from the false teeth and the tray. The denture is now complete except for smoothing any rough edges which may have formed. The latter is simply accomplished with a piece of sandpaper. When the completed denture 58 is placed over the gums a perfect fit results without having had to resort to the tedious, expensive and time consuming method of the prior art. If desirable the person can use a liner of soft material such as a gel type material between the denture and the gums for even greater adherence of the denture plate to the gums.
