Primary Examiner-Robert Peshock Attarney-Clarence A. OBrien and Harvey B..Jacobson [57] ABSTRACT Denture bases in a plurality of standard sizes are mass produced and stocked by dentists in order to tit and tailor a set of artificial dentures to an individual patient during a single visit. The standard denture bases are made by use of reusable mold assemblies which include cavity-forming bodies made of an elastically deformable material.
5 1 Claim, 6 Drawing Figures PREFABRICATED. DENTURE CONSTRUCTION AND METHOD This invention relates to the manufacture and fitting of artificial dentures.
The method of making and fitting artificial dentures in general use today, is relatively. time-consuming as well as expensive. Thus, for persons of low income in need of artificial dentures, an excessive economic burden is involved while for others, present methods are objectionable because of the inconvenience of time delays and discomforts incident thereto. Present methods ofmaking and fitting artificial dentures usually involve many visits to the dentists oflice in order to obtain impressions from which models are made, waiting periods between removal of teeth and fitting of dentures, custom manufacture of the dentures in a dental laboratory after. aselection of artificial teeth size and color is made as well as. tryouts, adjustments and finishing of the dentures. Fabrication of the dentures themselves in a dental lab usually involves waxingof models mounted on an articulator which simulates movement of the patients jaws, positioning of artificial teeth in order to approximate occlusal relationships, and casting the dentures in plaster molds made from the waxed up models.
The use of standard size dentures capable of being lined with -amoldable material so that it may be tailored to an individuals mouth, has been proposed, for example, in US. Pat. Nos. 2,685,133 and 3,335,495. While the methods disclosed in these patents represent an attempt to reduce the time involved in making and fitting artificial dentures by eliminating custom fabricating methods in present use, the techniques disclosed in these patents have not been adopted for several reasons.
While US. Pat. No. 2,685,133 to Greeneet al. discloses the concept of fabricatingstandard'size dentures, the value of making standard size dentures is lost unless they can be mass produced. Present known methods for making dentures are unsuitable since the plaster molds made in dental laboratories are not reusable and are destroyed or ruptured upon removal of the. denture from the mold.
U.S. Pat. No. 3,335,495 to Wichner is limited to the assembly of artificial teeth with the denture base utilizingan intermediate blank for this purpose. While it is desirable to interchangeably assemble artificial teeth with denture bases'in order to increase the number of denture combinations from which a selection may be made in order to fit an individual patient, from the standpoint of cost and structuraldurability the use of an additional intermediateblank is unsatisfactory.
it is therefore an important object of the present invention to provide a method for making and fitting artificial dentures utilizing standard size denture bases but avoiding the drawbacks associated with the disclosures in US. Pat. Nos. 2,685,133 and 3,335,495 aforementioned. Further, in accordance with the foregoing object, the present invention represents the first practical basis upon which artificial dentures may be fitted to individual patients by selection from standard size denture bases, utilizing the services of qualified practitioners in the dental profession.
in accordance with the present invention, standard size denture bases are capable of being mass produced by casting thereof in reusable molds. Toward this end, a sectional mold assembly is utilized made of an elastically deformable material within which the mold cavities are formed. Thus, removal of the cured denture base fromthe mold merely causes temporary deformation thereof without permanent distortion or rupture. A plurality of acrylic denture bases in different standard sizes may therefore be produced economically and stocked by each dentist employing the techniques of the present invention. A denture base may then be selected and fitted to an individual patient as described. for example in U.S. Pat. No. 2,685,133 to Greene et al. aforementioned. Also, a separate selection may be made of the artificial teeth both to the size and color by the dentist to suit the patient being fitted. In rare cases, the selected denture base may be cut or relieved in order to accommodate the patients mouth. The denture base may then be tailored to the patients mouth by lining thereof with the same acrylic denture base material in its plastic state. Thus, after the molded lining material has set, the excess is removed and the denture finished. The foregoing procedure may be carried out during a single visit to the dentist. Aside from the economy incident to the mass production of standard size denture bases as compared to custom fabrication in accordance with present methods, the present invention involves a considerable savings in time and less discomfort for the patient by making the denture base moldable lining; technique feasible.
These-together with other objects and'advantages which'will become subsequently apparent reside in the details of construction and operation as more. fully hereinafter described and claimed, reference being had to the accompanying drawings forrninga part hereof, wherein like numerals refer to like parts throughout, and in which:
FIG. 1 is a block diagram diagrammatically'illustrating the method of the present invention.
HO. 2 is a perspective view of the parts utilized in fitting and assembling apreformed denture in accordance with the present invention.
FIG. 3 is a partial sectional view taken substantially through a plane indicated by section line 3-3 in H6. 2.
FIG. 4 is an enlarged partial sectional view taken substantially through a plane indicated by section line 4-4 in H0. 2.
FIG. 5 is a sectional view through a sectional mold constructed in accordance with the present invention for casting a preformed, standard size denture.
FIG. 6 is a sectional view through a completed denture constructed and fitted in accordance with the present invention.
Referring now to the drawings in detail, FIGS. 2 and 3 illustrate typical parts which will be stocked in standard sizes by a dentist in order to practice the present invention. These parts include disposable ridge forms adapted to be inserted into a patients mouth in order to occupy the space normally occupied by an artificial denture, such as the upper "ridge form 10. it will of course be appreciated that there will also be standard size ridge forms adaptedto fit the lower jaw. The ridge forms are made of a relatively inexpensive, thin, transparent plastic material 12. These ridge fomis are stocked in standard sizes, therebeing up to 10 sizes in order to accommodate something like percent of all persons. Thus, with a set of corresponding standard size denture bases corresponding to the ridge forms, the standard size denture base dimensionallycloscst to a patient may be determined, such as the denture base 14 shown in FIGS. 2 and 3. Thedenture base is made of the same acrylic plastic as artificial denture bases heretofore custom made in accordance with present methods but differs therefrom in that the inner surface 16 of the denture base will not exactly conform to the tissue surfaces of the patient being fitted. Further, in one embodiment of the invention, the standard size denture base 14 is provided with a plurality of sockets 18 adapted to receive artificial teeth to be assembled with the denture base.
At the present time, it is contemplated that therewillbe 10 standard size upper and lower ridge forms and corresponding standard size upper and lower'denture bases. Also, artificial teeth of standard size and color will be stocked by the'dentist so that a selection may be made in accordancewith the size and color of teeth removed from a patient. The entire procedure in making and fitting dentures from the standard sized parts aforementioned is diagrammed in FIG. 1. As shown, the present invention contemplates mass production of the standard size ridge forms 10 and denture bases 14 from reusable molds 20 employing an injection molding process 22. FIG. 1 also diagrams the stock of artificial teeth 24 which may either be cast with the denture bases or embedded in the molds in order to directly bond the same to' the denture bases as an alternative to subsequent bonding of the artificial teeth within the sockets 18 of the denture bases as shown in F168. 2 and 3. P10. 1 also denotes the fitting step 26 by means of which the standard size denture base dimensionally closest to the jaw of the patient is determined so that a proper selection and assembly may be made as denoted by reference numeral 28. If necessary, the denture base may be cut in order to accommodate certain patients as denoted by reference numeral 30. The assembled denture is then lined on the inner surface by moldable lining material as denoted by reference numeral 32 in H6. 1 in order to tailor the denture to the jaw of the patient. After curing of the acrylic lining, any excess is removed and rough spots polished as indicated by the finishing station 34 in FIG. 1.
As hereinbefore indicated, a selection of artificial teeth is made by the dentist. The artificial teeth may be cast together with the denture bases or embedded in the molds from which the denture bases are cast for direct bonding to the denture bases. In the latter case, there will be standard combinations of denture base sizes and artificial teeth colors from which the dentist must make a selection both as to size and teeth color. The embodiment illustrated in FIGS. 2, 3 and 4 however involves assembly of separately cast denture bases 14 and artificial teeth made from acrylic or porcelain material. The artificial teeth may be selected from and assembled as separate groups of integrally connnected teeth including groups of posterior teeth 36 and anterior teeth 38. Each tooth will fit within one of the sockets 18 while bonding facilities will be provided for the end teeth in each group. The posterior teeth 36 for example, will include an end molar 40 and an end bicuspid 42 having recesses 44 formed therein for receiving projections 46 in those sockets 18 of the denture base corresponding to the end teeth. A suitable adhesive may also be utilized to coat the engaging surfaces of the sockets l8 and the end teeth received therein. Similarly, bonding facilities will be provided for the end teeth associated with the anterior groups 38 such as the cuspids on either side of the incisors.
FIG. illustrates a typical reusable mold assembly 48 within which a standard size lower denture base was cast such as the lower denture 50 shown in FIG. 6. ln this example, the artificial teeth 52 were directly bonded to the denture base 54 by embedding the teeth in the reusable mold assembly prior to introduction of the acrylic plastic mixture into the mold cavity 60. A conventional dental flask was utilized in connection with the mold assembly including lower and upper flask sections 56 and 66 as shown in FIG. 5. Bodies of elastically deformable material 58 and 64 cured from a settable mixture known as RTV" made by Dow-Corning Company was utilized exclusively as the cavity forming material. Standard size plaster models on which master dentures were positioned, were embedded in the mold material 64 and 58 while in a plastic state so as to form the mold cavity 60 between surfaces thereof in the flask sections 56 and 66. Thus, the plaster model itself is not utilized as part of the mold assembly. A separating medium 68 was utilized between the mold cavity bodies 58 and 64.
With the artificial teeth 52 embedded in the cured mold cavity body 58 as shown in FIG. 5, a plastic mixture of the acrylic material was introduced into the mold cavity 60 and cured to a rigid state directly bonding to the artificial teeth. The denture so formed was removed from the mold cavity without rupturing the mold body material despite the undercutting in the mold cavity in view of the elastically deformable property of the mold material. Thus, the mold assembly 48 was reused in order to form a large quantity of the same standard size dentures.
When a denture selection is made, it is tailored to the individual patient by lining a plastic mixture of acrylic on the inner surface such as indicated by reference numeral 70 in FIG. 6. The lining denture may then be molded directly within the patients mouth making sure that proper occlusal relationships and requirements are satisfied. After the lining has initially set, the denture may be removed from the patients mouth and the lining permitted to fully cure. Excess material squeezed out over the ridges of the denture may then be removed by an abrasive tool and rough spots polished in order to complete the denture.
The determination of the denture base size, the selection of artificial teeth, the assembly of the denture, the tailoring of the denture to the individual patient and the finishing thereof may all be performed during a single visit to the dentist. The foregoing procedure is of course made feasible by mass production of the standard size denture bases utilizing reusable molds as hereinbefore described.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
