Abstract
ABSTRACT OF THE DISCLOSURE
After a patient's teeth have become substantially perfectly aligned by a custom or preformed positioner, one or more selected depressions are filled with a liner material in a soft moldable state and having the property of hardening over a short period of time at body temperature and adhering to the positioner surface. The positioner is then placed in a patient's mouth with the teeth in place within their respective depressions.
The filling material in the selected depressions then forms to the outer contour of the teeth located therein and hardens, thereby providing in those depressions inner surfaces precisely fitted to the contour of their respective teeth.

Description
iO~9;~5~
This invention relates to tooth positioning appliances, and in particular it relates to improvements in such appliances for enhancing retention of tooth alignment.
In the field of orthodontics, conventional orthodontic devices such as bands or the like are often used for straightening teeth to bring them to a predetermined position or close to proper occlusion. To bring the teeth into a final position of desired orientation in the mouth, the orthodontist will often use a tooth positioner. One type of positioner which is custom-made for each individual patient is illustrated in the Kesling U.S, Patent NoO
This invention relates to tooth positioning appliances, and in particular it relates to improvements in such appliances for enhancing retention of tooth alignment.
In the field of orthodontics, conventional orthodontic devices such as bands or the like are often used for straightening teeth to bring them to a predetermined position or close to proper occlusion. To bring the teeth into a final position of desired orientation in the mouth, the orthodontist will often use a tooth positioner. One type of positioner which is custom-made for each individual patient is illustrated in the Kesling U.S, Patent NoO
2,467,432. Another type of positioner which is preformed in a limited number of sizes, and wherein the patient is fitted with the correct one of the limited number of sizes is shown in my Canadian Patent No. 897,464, issued April 11, 1972.
One problem which has been encountered in the use of this type of positioner is that when the teeth are properly aligned or essentially so, there is a tendency for the patient to reduce his enthusiasm for cooperation, as a result of which the essential-ly perfect result achieved at this point starts to relapse slightly as cooperation lags, Hence, there exists a need for providing im-provements in the art relating to orthodontic positioners of the present type which will enhance retention of tooth alignment through all stages of use thereof.
Thus, it is a purpose of the present invention to provide improvements in orthodontic positioners of the type described which will overcome the above described disadvantages which have existed hereto~ore.
This purpose of the present invention is achieved by modifying the inner surfaces of the positioner, after it has been used to bring the teeth into a desired alignment, by reshaping selected tooth depressions exactly to the outer contour of their respective teeth, to thereby firmly hold those selected teeth in ''X
':' ' ' iO6'~3Si a precise position, In accordance with a preferred embodiment, this reshaping is accomplished by introducing into the selected depressions a soft moldable material which has the property of hardening at body temperature after a short period of time and adhering perma-nently to the positioner itself, With this material, the position-er is placed into the patient's mouth, centered properly therein, and the patient is asked to close his teeth and hold them together for a few minutes until the material hardens, The positioner is then removed and when the material has completely hardened it is trimmed at the margins of the tooth depressions. As a result, there is provided a tooth positioner originally preformed or cus-~ tom-made for the purpose of moving teeth to a desired position, and -~ further including a liner material within selected tooth depressions, which liner is shaped essentially precisely to the outer contour or the tooth received therein, thereby firmly holding this tooth in the position which it has reached up to this pointO The pre-sent invention is applicable of course to either a maxillary po-sitioner, a mandibular positioner or a combined maxillary-mandi-bular positioner. In the latter case, it is preferable although not absolutely necessary to work with one half of the positioner at a time, first reshaping the depressions on either the upper to the lower half, and then subsequently reshaping the depressions on the other half, The material of the liner may be one that becomes rela-tively hard at body temperature or one which is relatively resi-lient or rubber-like at body temperature, If a hard material is used, it has the advantage that the positioner will snap in place quite firmly as the occlusal surfaces of the teeth move into their respective depressions, pushing aside the hard material at the gingival edges of the depressions which are provided for pressing against the undercut portions of the teeth adjacent the gums when ~, ~,,~
- - . . ~ . - ~ - .
10~9351 the teeth are firmly iD place in their respective depressions.
Alternatively, if the liner material is relatively resilient, it might not have the same firm positive action as with a harder ma-~- terial but apparently with a resilient material it is possible to more closely and precisely fit the outer contour of the teeth.
Indeed, the advantages of both the hard and the soft materials can be achived in a single embodiment utilizing a material which is hard at body and room temperature but which becomes rubbery a few degrees thereabove, This material can have the advantages of both in that the patient can warm the finished relined positioner in hot water, place it in his mouth after which it will slowly ; harden and function like the hard liner material by firmly holding the teeth in place.
Many materials are known which could be utilized to form the liner material. Preferably, materials would be used which would polymerize chemically bond with or otherwise strongly adhere to the material of the positioner itself or with an additional ma-terial applied thereto for that purpose. For example, the prefor-med or custom positioner could be made of a polymer or copolymer of the same material or of a material one which would provide an adhering surface for the insert material. This might include for example a material with a small percentage by weight of acrylic resin which would thus provide a perfect adhering surface for a self-cure acrylic polymer which would remain permanently attached theretoO A methyl-methacrylate monomer may be painted on the sur-face of the positioner where the liner material is to be added, after which this monomer and the self-cure acrylic polymer are mixed into a runny consistency and placed onto the said painted surfaceO With the positioner in this state, the positioner would be placed into the patient's mouth, centered properly, and the pa-tient would be asked to close his teeth and hold them together for a couple of minutes until the material hardens. After hardening, 4 ;~
s lO~Y1351 the material would he trimmed and polished.
Thus, it is an object of the present invention to pro-vide an orthodontic positioner of the type described, with certain portions thereof reshaped so as to retain retention of a previously attained tooth alignment.
It is another object of this invention to provide a me-thod for utilizing an orthodontic positioner so as to enhance re-tention of tooth alignment, said method including first utilizing the positioner for a predetermined period of time so as to achieve a desired, preferably perfect, alignment of the teeth, and then reshaping the interior of certain tooth depressions so as to pre-;~ cisely and firmly adapt to the outer contour of their respective teeth.
The invention is particularly directed toward an ortho-dontic tooth positioning and retaining appliance which is generally U-shaped in plan view and which has a tooth receiving trough ge-nerally of a size and shape for reception of a patient's teethO
The trough is made of an elastomeric material, and has one or more selected depressions therein shaped substantially precisely to the outer contour of its repsective tooth sufficiently to hold its respective tooth in a fixed position relative to the positioner.
The positioner comprises a substrate in the shape of a conventional positioner shaped to correct and retain teeth within the patient's mouth, and includes a liner forming a discontinuous phase with res-pect to the substrate within the selected one or more depressions to form the portion of outer contour of the selected teeth.
Other objects and advantages of the present invention will become apparent from the detailed description to follow, together with the accompanying drawings.

Referring now to the drawings, like elements are repre-sented by like numerals throughout the several views.
30Figure 1 illustrates a conventional preformed or custom positioner of the type with which the present invention is concer-~; ned. After the bands have been removed a positioner of this type ~069351 is used to effect limited final movement of the teeth and then to retain those teeth in that final position. To accomplish this, the positioner 10 has formed between a labial-buccal flange 13 and a lingual flange 14 upper and lower troughs 11 and 12, each of which have tooth depressions therein. The depressions starting with the right lateral incisor back to the second molar are repre-sented by numerals 15a through 15 g. Similarly, depressions for ; the lower teeth would be formed into the trough 12. Alternatively, positioners can be provided which are solely for the mandibular teeth or solely for the maxillary teeth. In any event, these de-pressions as represented in figure 1 by 15a through 15g are shaped so as to actually exert a physical moving force upon a tooth recei-ved therein so as to move that tooth to a selected final position of alignment. To accomplish, the positioner must of course engage the tooth at one point and be free of engagement with that tooth at at least some other points on the contour of that tooth.
The difficulty then arises at that point in time wherein tooth movement has been completed so as to bring the teeth into an essentially perfect alignment. At this point there is a clear tendency for the patient to reduce his enthusiasm, the consequence of this being the commencement of relapse.
The present invention overcomes this problem by providing in certain selected tooth depressions a liner material which in essence reshapes that depression so as to essentially exactly fit the outer contour of the tooth received therein, This is in con-trast to the original shape of each depression wherein there was normally a space between the inner surfaces of the depression and at least some surfaces of the teeth. One important portion of the liner is that which mates with the undercut portion of the tooth adjacent the gum. Prior to the reshaping of the present invention, the surfaces of the,depression tended to move straight towards the gum so as to not block movement-of the occlusal edges of the tooth .., :, 10~i9351 into and out of the depression. With the present invention, how-ever, there will be this new portion adjacent the outer edges of the depression adapted to mate with the undercut portion of the teeth adjacent the gum and hence possibly blocking ~ovement of the larger occlusal edges of the teeth into that depression, The result will be that to move that tooth into the depression it will have to move aside these said portions of the liner adapted to mate with the undercut portions of the teeth, these latter portions then snapping back into place after the tooth has completed its movement into the depression, whereby the liner material firmly engages the tooth to hold it firmly in that specific position.
Figure 2 illustrates the positioner of figure 1 wherein the depressions include the liner material therein which exactly mates to the outer contour of the teeth. While figure 2 illus-trates all of the visible depressions as having liner material therein, it will be understood that the concept of reshaping the depressions can be applied to a single depression or to any combi-nation of tooth depressions, In some cases it may be preferable to reshape only the anterior tooth receiving depressions although the invention of course encompasses reshaping any one or any com-bination of depressions.
Although the preceding discussion has concerned itself primarily with the end result of filling in the tooth depressions, in practice the procedure can be relatively simplified by proceed-ing in a manner wherein an entire trough such as the upper trough 11 can be filled with the soft moldable material as the positioner ;
is placed into the patient's mouthO As the patient then occluded his teeth, excess material would move not only into that portion of the trough above the depressions, but possibly also up over the edges of flanges 13 and 14, The positioner is preferably removed from the patient's mouth after the liner material has hardened slightly but before it has completely hardenedO In this state the ~ i .
~ 93~1 material is preferably still sufficiently soft that it can be easi-ly trimmed from the areas above the depressions with a suitable cutting instrument.
Figures 2 through 6 illustrate the positioner of figure 1 modified with all of the upper tooth receiving depressions reli-ned to precisely fit the outer contours of their respective upper teeth. Figures 3 and 4 illustrate the upper lateral incisor tooth depression 15a with the liner material 21 thereinO In figure 3 the liner material 21 is shown as it might extend slightly up into the space between this tooth and its adjacent tooth while figure 4 illustrates how the material might run up to -the upper edge of depression 15a so as to mate with the undercut portions of the la-bial and lingual sides of the tooth. Figure 3A and 4A then illus-trate this modified depression of figures 3 and 4 with a lateral incisor tooth 20 located therein.
; Figures 5 and 6 illustrate the molar tooth depression 15f with the liner material 26 therein. Figures 5A and 6A illus-trate how the liner material closely adapts to the ou$er surfaces, and in particular the undercut portions of molar tooth 25.
The liner may be formed of any material which can ini-tially be formed into a soft moldable state and which will harden after a short period of time and firmly adhere to the surface of the positioner itself. "Harden" in this sense may include a very stiff consistency or a rubber-like consistency. Alternatively a material may be selected which is very stiff at room and body tem-perature but which becomes slightly rubber-like a few degrees the-` reabove. One specific material, vinyl-acrylic copolymers, were mentioned above. Another preferable material is silicone rubber.
However, there are of course numerous other materials which would strongly adhere to the positioner itself, preferably by polymeriz-ing therewith. For example, a monomer can be applied to the sur-~; face of the substrate with a copolymer thereover of essentially _ 9 _ , ~
1~6C~351 the same material as the monomer or the positioner so as to cause polymerization therebetween. In any event, these techniques are well known in the chemical arts so that a further detailed descrip-tion thereof is not necessary. In any event, since the liner will have been added at a later point in time then the actual formation of the positioner, its molecular structure will tend to form a line of demarcation with the surface of the positioner so that if one views a cross-section cut through both the liner and the ma-terial, it will be evident that they constitute phases which are discontinuous at their interface so that the liner can be said to form a discontinuous phase with the material of the positioner itself.
Although the invention has been described in conside-rable detail with respect to preferred embodiments thereof, it will be apparent that the invention is capa~le of numerous modifi-cations and variations apparent to those skilled in the art with-out departing from the spirit and scope of the invention.

One problem which has been encountered in the use of this type of positioner is that when the teeth are properly aligned or essentially so, there is a tendency for the patient to reduce his enthusiasm for cooperation, as a result of which the essential-ly perfect result achieved at this point starts to relapse slightly as cooperation lags, Hence, there exists a need for providing im-provements in the art relating to orthodontic positioners of the present type which will enhance retention of tooth alignment through all stages of use thereof.
Thus, it is a purpose of the present invention to provide improvements in orthodontic positioners of the type described which will overcome the above described disadvantages which have existed hereto~ore.

10~9351 the teeth are firmly iD place in their respective depressions.
Alternatively, if the liner material is relatively resilient, it might not have the same firm positive action as with a harder ma-~- terial but apparently with a resilient material it is possible to more closely and precisely fit the outer contour of the teeth.
Indeed, the advantages of both the hard and the soft materials can be achived in a single embodiment utilizing a material which is hard at body and room temperature but which becomes rubbery a few degrees thereabove, This material can have the advantages of both in that the patient can warm the finished relined positioner in hot water, place it in his mouth after which it will slowly ; harden and function like the hard liner material by firmly holding the teeth in place.

After hardening, 4 ;~

Thus, it is an object of the present invention to pro-vide an orthodontic positioner of the type described, with certain portions thereof reshaped so as to retain retention of a previously attained tooth alignment.

30Figure 1 illustrates a conventional preformed or custom positioner of the type with which the present invention is concer-~; ned. After the bands have been removed a positioner of this type ~069351 is used to effect limited final movement of the teeth and then to retain those teeth in that final position. To accomplish this, the positioner 10 has formed between a labial-buccal flange 13 and a lingual flange 14 upper and lower troughs 11 and 12, each of which have tooth depressions therein. The depressions starting with the right lateral incisor back to the second molar are repre-sented by numerals 15a through 15 g. Similarly, depressions for ; the lower teeth would be formed into the trough 12. Alternatively, positioners can be provided which are solely for the mandibular teeth or solely for the maxillary teeth. In any event, these de-pressions as represented in figure 1 by 15a through 15g are shaped so as to actually exert a physical moving force upon a tooth recei-ved therein so as to move that tooth to a selected final position of alignment. To accomplish, the positioner must of course engage the tooth at one point and be free of engagement with that tooth at at least some other points on the contour of that tooth.
The difficulty then arises at that point in time wherein tooth movement has been completed so as to bring the teeth into an essentially perfect alignment. At this point there is a clear tendency for the patient to reduce his enthusiasm, the consequence of this being the commencement of relapse.
The present invention overcomes this problem by providing in certain selected tooth depressions a liner material which in essence reshapes that depression so as to essentially exactly fit the outer contour of the tooth received therein, This is in con-trast to the original shape of each depression wherein there was normally a space between the inner surfaces of the depression and at least some surfaces of the teeth. One important portion of the liner is that which mates with the undercut portion of the tooth adjacent the gum. Prior to the reshaping of the present invention, the surfaces of the,depression tended to move straight towards the gum so as to not block movement-of the occlusal edges of the tooth .., :, 10~i9351 into and out of the depression. With the present invention, how-ever, there will be this new portion adjacent the outer edges of the depression adapted to mate with the undercut portion of the teeth adjacent the gum and hence possibly blocking ~ovement of the larger occlusal edges of the teeth into that depression, The result will be that to move that tooth into the depression it will have to move aside these said portions of the liner adapted to mate with the undercut portions of the teeth, these latter portions then snapping back into place after the tooth has completed its movement into the depression, whereby the liner material firmly engages the tooth to hold it firmly in that specific position.
Figure 2 illustrates the positioner of figure 1 wherein the depressions include the liner material therein which exactly mates to the outer contour of the teeth. While figure 2 illus-trates all of the visible depressions as having liner material therein, it will be understood that the concept of reshaping the depressions can be applied to a single depression or to any combi-nation of tooth depressions, In some cases it may be preferable to reshape only the anterior tooth receiving depressions although the invention of course encompasses reshaping any one or any com-bination of depressions.
Although the preceding discussion has concerned itself primarily with the end result of filling in the tooth depressions, in practice the procedure can be relatively simplified by proceed-ing in a manner wherein an entire trough such as the upper trough 11 can be filled with the soft moldable material as the positioner ;
is placed into the patient's mouthO As the patient then occluded his teeth, excess material would move not only into that portion of the trough above the depressions, but possibly also up over the edges of flanges 13 and 14, The positioner is preferably removed from the patient's mouth after the liner material has hardened slightly but before it has completely hardenedO In this state the ~ i .
~ 93~1 material is preferably still sufficiently soft that it can be easi-ly trimmed from the areas above the depressions with a suitable cutting instrument.

Figures 3 and 4 illustrate the upper lateral incisor tooth depression 15a with the liner material 21 thereinO In figure 3 the liner material 21 is shown as it might extend slightly up into the space between this tooth and its adjacent tooth while figure 4 illustrates how the material might run up to -the upper edge of depression 15a so as to mate with the undercut portions of the la-bial and lingual sides of the tooth. Figure 3A and 4A then illus-trate this modified depression of figures 3 and 4 with a lateral incisor tooth 20 located therein.
; Figures 5 and 6 illustrate the molar tooth depression 15f with the liner material 26 therein. Figures 5A and 6A illus-trate how the liner material closely adapts to the ou$er surfaces, and in particular the undercut portions of molar tooth 25.
The liner may be formed of any material which can ini-tially be formed into a soft moldable state and which will harden after a short period of time and firmly adhere to the surface of the positioner itself. "Harden" in this sense may include a very stiff consistency or a rubber-like consistency. Alternatively a material may be selected which is very stiff at room and body tem-perature but which becomes slightly rubber-like a few degrees the-` reabove. One specific material, vinyl-acrylic copolymers, were mentioned above. Another preferable material is silicone rubber.
However, there are of course numerous other materials which would strongly adhere to the positioner itself, preferably by polymeriz-ing therewith. For example, a monomer can be applied to the sur-~; face of the substrate with a copolymer thereover of essentially _ 9 _ , ~
