- the flexible shell utilized as a combined fitting aid and impression tray during formation of the mouth protector 10 is illustrated generally in FIGS. 1-5 inclusive, and will be designated by reference numeral 20.
- the mouth protector device 10 comprises a U-shaped body member 12 having a channel portion 14 extending substantially the entire length thereof. There are provided a pair of marginal walls, 16 and 18 respectively and a pair of curved end walls closing off the channel 14.
- the marginal wall 16 serve as the labial wall of the mouthpiece while the marginal wall 18 is defined as forming the palatal wall thereof.
- the body member 12 comprises a flexible, thin walled outer shell and an inner lining 22, the inner lining being formed of a resilient formable plastic composition hereinafter described. Said inner lining defines .a first dental impression 23 of the upper set of teeth of the wearer and is formed as a series of cavities, 24 and 26, and a pair of opposed wall linings 28 and 29.
- the cavities 24 and 26 are intended to accommodate the anterior or incisal upper teeth of the wearer and the posterior teeth respectively.
- a second impression is provided on the undersurface of the body 12 coextensive with the length of the arms thereof and in registry with the lower posterior teeth of the wearer.
- the labial wall 16 is canted only slightly rearwardly so as to define an angle only slightly less than 90 degrees relative said channel 14. -In fact, said wall 16 may be defined as sloping only slightly over the periphery of channel 14.
- the palatal wall 18, however, is severely oanted outwardly at an angle much greater than 90 in a direction away from the channel 14 whereby to form an arcuate palatal cover for the mouth protector 10.
- the wall lining 28 extends above the labial wall 16 so that the entire labial section of the wearers jaw is covered with the resilient material.
- the inner 'bight 30 of the U-shaped member 12 is provided with a shallow cavity 32 extending into the palatal Wall 18 and along the adjacent edge of the channel formation 14.
- This cavity shall be defined as forming an incisal shelf in view of its function to provide a contact or hearing surface for the lower anterior teeth when the mouth protector 10 is installed.
- the shell 20 is formed of molded construction preferably of thin gauge vinyl-plastic material.
- the said shell 20 comprises a U-shaped body having a channel 42 defined by a labial wall 44, a palatal Wall 46, and end walls 48 closing off same.
- the labial wall 44 is canted only slightly inwardly with its greater height located adjacent the bight of the U-shaped shell and then grad ually tapering toward ends thereof.
- the palatal wall 46 extends from end walls 48 and is canted severely. The height of wall 46 increases in a direction toward the bight 50 of the U-shaped shell 20.
- the palatal wall 46 is intended to act as a palatal cover and it is contemplated that only about 'onethird of the hard palate of the user is engaged during formation and use of the mouthpiece, thereby assuring a good fit without interference with tongue action, breathing and like body processes under the strain of exertion, competition and impact.
- the U-shaped floor '52 of the channel 42 comprises an imperforate web 56 at the bight 50 of the shell 20 and a mesh web portion 58 provided along the length of each of the arms of the floor 42. Coextensive with the said mesh web portion 58, and depending downwardly from the marginal edges thereof, a rim or fence 60 is provided.
- the fence 60 aid-s in retaining filler material in a restricted area as it is forced through the mesh web portion 58 during the taking of the first and second dental impressions.
- the fence 60 also serves to limit the occlusal thickness of the filler material to reduce the occlusal thickness or bite area of the mouthpiece at the areas concerned.
- Thes hell 20 is also provided with a connecting web 62 integral with the palatal wall 18 and joining the arms of the U-shaped body 40 closely adjacent the ends thereof. Since the shell member 20 is light weight and flexible, the same, when used as an impression tray, has a tendency to distort and/or spread during even the short period of time it is held in the mouth as the dental impressions are taken. Such spreading or distortion is substantially reduced by the restraining action of connecting Web 62. Web 62 also aids in positioning the shell in the mouth as will be later described so that accurate adjustments of the labial and palatal walls may be made during fitting and the exact dental impressions taken. Subsequent to formation of the mouth protector, the web 62 may be severed and removed.
- composition of the filler or mastic material comprising the impression bearing lining 22 of the mouth protector 10.
- Primary requisites of such material include capability of same to adhere to the wall surfaces of the shell member, freedom from deleterious physiological effects on the wearer, capability to be formab'le so as to act as a carrier for a dental impression, ability to have a semi-solid state which will harden to a second state in which the same is resilient and shock resistant, but capable of retaining the impression formed therein, and capable of setting to the second state within the mouth at body temperature and within a short length of time.
- a composition discovered to have the properties described above comprises a flexible polymerized acrylic resin compound.
- Said compound preferably may be supplied in the form of a powder, for example, consisting entirely of an ethyl methacrylate resin in powder form, and a liquid consisting of methyl methacrylate monomer, a suitable plasticizer, for example, of the group dibuty-l pthalate, and a solvent, such as ethyl alcohol.
- An example of the composition which was successfully used to form a mouthpiece of the invention is as follows.
- Methyl methacrylate monomer 2 Di-butyl phthalate 68 Ethyl alcohol 30
- the powder and liquid were mixed in equal quantities to form a semi-solid flowable paste taking great care to avoid incorporation of air in the paste. This may be done by the well known dental technique of spatulating and may be accomplished within a very short period of time. The composition thus compounded is now ready for use.
- the shell member 20 is first tried on or preliminarily fitted to the conformation of the wearers upper oral cavity.
- the shell 20 is inserted in the wearers mouth and the labial wall 44 is examined to determine the extent of coverage of the labial sector of the upper jaw formation.
- the wearer is instructed to bite upon the floor 52 to discover any impingement of tissue at the upper edges of the wall 44.
- the wall 44 may be trimmed with a scissors so as to insure a denture-like fit.
- the palatal wall 18 is then inspected to insure that the palate tissue is covered to the extent desired.
- the said palatal wall 18 may be similarly adjusted with the aid of a scissors by trimming same or merely by cutting down the mid-die of the wall 18 to insure coverage.
- the wearer is then instructed to open his mouth and the occlusal fit is inspected, that is the registry of the end walls 48 with the posterior border of the upper set of teeth so as to enclose same. Should the arms of the U- shaped shell member 20 not be spread far enough to assure proper occlusal fit, then the connecting web 62 must be severed.
- a composition such as described above is formulated and mixed. Although the composition is a thick semisolid, it is still flowable due to the presence of the solvent therein. The composition is then poured into the fitted shell 20 until the channel 42 is filled to about three quarters of its capacity. The composition is permitted to flow through the mesh portions 58 to the level of the fences 60. Some of the composition may be used to cover the underside of the mesh portion 58 to the level of the fence 60, same being applied preferably by spatula to prevent air bubbles from being trapped therein.
- the solvent is permitted to evaporate to a degree where the paste becomes thicker, resistant to touch and no longer flows freely. This action generally takes about one or two minutes.
- the shell 20 with the composition therein is inserted into the mouth of the wearer so that the end walls 48 clear the last molars at the posterior section of the upper set of teeth.
- the shell 20 is then swung upward so that the posterior teeth are seated therein, with the anterior teeth subsequently engaged by way of a continued upward and forward movement, taking care to lift the upper lip formation of the wearer whereby to insure correct labial wall contact.
- the wearer is then instructed to place his tongue upon the connecting web 62 and press the said web against the upper palate. This action aids in properly seating the shell 20 and establishes the correct bite.
- the wearer then closes his mouth until full contact is reached between the lower teeth and the undersurface of the said shell. With the bite of the wearer, the filler material is forced through the mesh portion 58 to form the lower impression 25. Thus the normal bite distance is maintained with only the slight thickness of the mesh between impressions 23 and 25.
- the wearer then moves his cheeks from side to side for about ten seconds to adjust the impression being taken, and the shell 20 is then retained in position until the filled composition has set, generally five minutes elapsing.
- the shell 20 with the inner lining 22 now formed is subsequently trimmed to remove any excess filler material particularly gathered around the fence 60.
- the connecting web 62 may be then removed. Now the mouthpiece 10 is formed and ready for use.
- the filler composition of the invention may be utilized as a repair mixture in the event that future repairs are required.
- a mouth protector device to be used by athletes and the like wearers and capable of in situ, custom fitting to the wearer, said mouth protector device comprising a U-shaped body member having a frontal arcuate portion and rearwardly extending lateral arm portions integral with the frontal arcuate portion and forming the said U-shaped body member thereby, said U-shaped body member having a relatively fiat planar U-shaped floor, upstanding marginal U-shaped labial and palatal walls and connecting end walls about the floor to provide a channel formation in cooperation with said floor, and said channel formation having a lining permanently adhered therein and adapted to carry an impression of the upper teeth of the wearer, said body member comprising, a thin walled, flexible, preformed shell of substantially uniform thickness adapted to serve as a fitting device and impression receiving tray during formation of the mouthpiece and incorporated permanently in the protector device during the fitting and formation of the device, said marginal walls and end walls having their exterior surfaces exposed in the finally formed device, said labial and palatal walls being canted in similar directions,
- the mouth protector device claimed in claim 1 in which there is a removable palatal web bridging the ends of the lateral arm portions opposite the frontal portion to serve as guide means during fitting and to prevent spreading of the arm portions during formation of said device.
Description
Sept. 21, 1965 s. GOLDSTEIN MOUTH PROTECTOR DEVICE Filed Dec. 3, 1962 INVENTOR, Sol. GIOLDSTEIN United States Patent 3,207,153 MOUTH PROTECTOR DEVICE Sol Goldstein, Skokie, Ill., assignor to Harry J. Bosworth Company, Chicago, 111., a corporation of Illinois Filed Dec. 3, 1962, Ser. No. 241,786 3 Claims. (Cl. 128'136) This invention relates generally to mouth protector devices for use by athletes and more articularly, relates to improvements in a mouth protector device of the character described whereby the same is more comfortable during use and affords better protection to the wearer than prior devices. Further, the invention relates to a novel method of fitting and forming the protector to an individual wearer with greater speed, accuracy and efficiency.
Protective devices in the form of mouthpieces for use by athletes engaged in contact sports are well known. Such devices generally are intended for insertion \and retention in the mouth of the wearer during use and corn prise U shaped, trough-bearing body members formed of thick, but resilient material such as rubber or plastic compositions. The devices are shaped to conform to the dental structure of the user whereby the walls thereof are canted to conform to the labial and palate while the trough or channel is provided with resilient bearing surfaces shaped to receive the teeth. Thus, the shock of a blow applied to the jaw area will be absorbed or distributed over the entire mouth area relieving the danger arising from the concentrated impact power of the blow and resultant damage to the teeth, lips, gums or tongue sometimes occurring as a result of an involuntary reflex reaction of the jaw to the said impact.
While devices heretofore provided have been satisfactory, several disadvantages have been encountered both in their use and in the forming and fitting thereof. Among such disadvantages are the need for the wearer to exercise substantial bite pressure in order to retain the mouthpiece in position, resulting interference with breathing in the installed position of the mouthpiece due to its bulkiness, and substantial difficulty in forming and fitting the device to each individual. A common result traceable to the aforementioned characteristics was that the athlete quickly became tired in the efforts required to retain prior devices in the mouth.
It is the principal object of the invention to provide a mouth protecting device for use by athletes which substantially eliminates the disadvantages enumerated above.
Another object of the invention is to provide a mouth protector of the character described having a thin walled, preformed flexible outer shell and a resilient lining in said shell, the said lining formed with a first dental impression of the upper teeth of the individual wearer, said device shell portion also having a second dental impression of the lower posterior teeth of the wearer whereby to realize registration of the upper and lower posterior teeth of the wearer in the installed position of said device.
In connection with the above mentioned object, the invention provides means for forming such lower second dental impression with a minimum bite opening so as to prevent bulkiness, chew through, and reducing the occurrence of tongue and breathing interference.
In addition, an important object of the invention is the provision of a thin walled, preformed outer shell for a mouth protector device which shell is adapted to serve as a fitting device and impression receiving tray during formation of the device, and an outer supporting wall for the device subsequent to the formation thereof, said shell comprising a flexible U-shaped member of molded plastic composition having a channel therein defined by a pair of upstanding marginal walls, said walls adapted to seat respectively on the upper labial and palate sections within the mouth, the channel having means for forming simul ice taneously said above mentioned first and second dental impressions.
Further, an object of the invention is to provide the last mentioned shell of the character described with a severable and removable connecting web between the two arms thereof, said web serving as a fitting aid and prevent spreading of the shell during the formation of the mouth protector device, and being optionally severable subsequent to the formation thereof.
Another important object of the invention is the provision of a pre-formed, flexible shell of thin wall construction adapted to serve as a fiittng and forming impression tray and which is adapted to be permanently incorporated as the outer wall of the finished mouthpiece, and shell being provided with a mesh-like formation and said formation being so located to permit a semi-solid plastic material to flow therethrough, whereby to permit a second impression of the lower posterior teeth to be formed simultaneously with a first impression of the upper set of teeth, and means being provided to retain the plastic material within the peripheral edge of the meshlike formation.
The objects of the invention also include the provision of a novel filler composition for the mouthpiece of the character described as well as a novel method of fitting and forming the said mouthpiece.
Other objects and advantages will become apparent as a detailed description of a preferred embodiment of the invention is set out below. It is evident that minor changes in construction, composition, dimensions and the like may be made without departing from the spirit and scope of the invention as defined in the claims appended hereto.

The flexible shell utilized as a combined fitting aid and impression tray during formation of the mouth protector 10 is illustrated generally in FIGS. 1-5 inclusive, and will be designated by reference numeral 20.
Generally, the mouth protector device 10 comprises a U-shaped body member 12 having a channel portion 14 extending substantially the entire length thereof. There are provided a pair of marginal walls, 16 and 18 respectively and a pair of curved end walls closing off the channel 14. The marginal wall 16 serve as the labial wall of the mouthpiece while the marginal wall 18 is defined as forming the palatal wall thereof. The body member 12 comprises a flexible, thin walled outer shell and an inner lining 22, the inner lining being formed of a resilient formable plastic composition hereinafter described. Said inner lining defines .a first dental impression 23 of the upper set of teeth of the wearer and is formed as a series of cavities, 24 and 26, and a pair of opposed wall linings 28 and 29. The cavities 24 and 26 .are intended to accommodate the anterior or incisal upper teeth of the wearer and the posterior teeth respectively. A second impression is provided on the undersurface of the body 12 coextensive with the length of the arms thereof and in registry with the lower posterior teeth of the wearer. The labial wall 16 is canted only slightly rearwardly so as to define an angle only slightly less than 90 degrees relative said channel 14. -In fact, said wall 16 may be defined as sloping only slightly over the periphery of channel 14. The palatal wall 18, however, is severely oanted outwardly at an angle much greater than 90 in a direction away from the channel 14 whereby to form an arcuate palatal cover for the mouth protector 10.
The wall lining 28 extends above the labial wall 16 so that the entire labial section of the wearers jaw is covered with the resilient material.
The inner 'bight 30 of the U-shaped member 12 is provided with a shallow cavity 32 extending into the palatal Wall 18 and along the adjacent edge of the channel formation 14. This cavity shall be defined as forming an incisal shelf in view of its function to provide a contact or hearing surface for the lower anterior teeth when the mouth protector 10 is installed.
The shell 20 is formed of molded construction preferably of thin gauge vinyl-plastic material. The said shell 20 comprises a U-shaped body having a channel 42 defined by a labial wall 44, a palatal Wall 46, and end walls 48 closing off same. The labial wall 44 is canted only slightly inwardly with its greater height located adjacent the bight of the U-shaped shell and then grad ually tapering toward ends thereof. The palatal wall 46 extends from end walls 48 and is canted severely. The height of wall 46 increases in a direction toward the bight 50 of the U-shaped shell 20. The palatal wall 46 is intended to act as a palatal cover and it is contemplated that only about 'onethird of the hard palate of the user is engaged during formation and use of the mouthpiece, thereby assuring a good fit without interference with tongue action, breathing and like body processes under the strain of exertion, competition and impact.
The U-shaped floor '52 of the channel 42 comprises an imperforate web 56 at the bight 50 of the shell 20 and a mesh web portion 58 provided along the length of each of the arms of the floor 42. Coextensive with the said mesh web portion 58, and depending downwardly from the marginal edges thereof, a rim or fence 60 is provided. The fence 60 aid-s in retaining filler material in a restricted area as it is forced through the mesh web portion 58 during the taking of the first and second dental impressions. The fence 60 also serves to limit the occlusal thickness of the filler material to reduce the occlusal thickness or bite area of the mouthpiece at the areas concerned. Thes hell 20 is also provided with a connecting web 62 integral with the palatal wall 18 and joining the arms of the U-shaped body 40 closely adjacent the ends thereof. Since the shell member 20 is light weight and flexible, the same, when used as an impression tray, has a tendency to distort and/or spread during even the short period of time it is held in the mouth as the dental impressions are taken. Such spreading or distortion is substantially reduced by the restraining action of connecting Web 62. Web 62 also aids in positioning the shell in the mouth as will be later described so that accurate adjustments of the labial and palatal walls may be made during fitting and the exact dental impressions taken. Subsequent to formation of the mouth protector, the web 62 may be severed and removed.
Attention is now directed to the composition of the filler or mastic material comprising the impression bearing lining 22 of the mouth protector 10. Primary requisites of such material include capability of same to adhere to the wall surfaces of the shell member, freedom from deleterious physiological effects on the wearer, capability to be formab'le so as to act as a carrier for a dental impression, ability to have a semi-solid state which will harden to a second state in which the same is resilient and shock resistant, but capable of retaining the impression formed therein, and capable of setting to the second state within the mouth at body temperature and within a short length of time.
A composition discovered to have the properties described above comprises a flexible polymerized acrylic resin compound. Said compound preferably may be supplied in the form of a powder, for example, consisting entirely of an ethyl methacrylate resin in powder form, and a liquid consisting of methyl methacrylate monomer, a suitable plasticizer, for example, of the group dibuty-l pthalate, and a solvent, such as ethyl alcohol. An example of the composition which was successfully used to form a mouthpiece of the invention is as follows.
Powder: Percent Ethyl methacrylate resin Liquid:
Methyl methacrylate monomer 2 Di-butyl phthalate 68 Ethyl alcohol 30 The powder and liquid were mixed in equal quantities to form a semi-solid flowable paste taking great care to avoid incorporation of air in the paste. This may be done by the well known dental technique of spatulating and may be accomplished within a very short period of time. The composition thus compounded is now ready for use.
In forming the mouthpiece 10, the shell member 20 is first tried on or preliminarily fitted to the conformation of the wearers upper oral cavity. The shell 20 is inserted in the wearers mouth and the labial wall 44 is examined to determine the extent of coverage of the labial sector of the upper jaw formation. The wearer is instructed to bite upon the floor 52 to discover any impingement of tissue at the upper edges of the wall 44. If necessary, and because the entire shell is of thin flexible material, the wall 44 may be trimmed with a scissors so as to insure a denture-like fit. The palatal wall 18 is then inspected to insure that the palate tissue is covered to the extent desired. The said palatal wall 18 may be similarly adjusted with the aid of a scissors by trimming same or merely by cutting down the mid-die of the wall 18 to insure coverage.
The wearer is then instructed to open his mouth and the occlusal fit is inspected, that is the registry of the end walls 48 with the posterior border of the upper set of teeth so as to enclose same. Should the arms of the U- shaped shell member 20 not be spread far enough to assure proper occlusal fit, then the connecting web 62 must be severed.
With comfort being generally determined through manipulation of the shell 20, the dental impression is now ready to be taken and the mouthpiece formed.
A composition such as described above is formulated and mixed. Although the composition is a thick semisolid, it is still flowable due to the presence of the solvent therein. The composition is then poured into the fitted shell 20 until the channel 42 is filled to about three quarters of its capacity. The composition is permitted to flow through the mesh portions 58 to the level of the fences 60. Some of the composition may be used to cover the underside of the mesh portion 58 to the level of the fence 60, same being applied preferably by spatula to prevent air bubbles from being trapped therein.
The solvent is permitted to evaporate to a degree where the paste becomes thicker, resistant to touch and no longer flows freely. This action generally takes about one or two minutes. The shell 20 with the composition therein is inserted into the mouth of the wearer so that the end walls 48 clear the last molars at the posterior section of the upper set of teeth. The shell 20 is then swung upward so that the posterior teeth are seated therein, with the anterior teeth subsequently engaged by way of a continued upward and forward movement, taking care to lift the upper lip formation of the wearer whereby to insure correct labial wall contact.
The wearer is then instructed to place his tongue upon the connecting web 62 and press the said web against the upper palate. This action aids in properly seating the shell 20 and establishes the correct bite. The wearer then closes his mouth until full contact is reached between the lower teeth and the undersurface of the said shell. With the bite of the wearer, the filler material is forced through the mesh portion 58 to form the lower impression 25. Thus the normal bite distance is maintained with only the slight thickness of the mesh between impressions 23 and 25. Using steady but not undue bite pressure, the wearer then moves his cheeks from side to side for about ten seconds to adjust the impression being taken, and the shell 20 is then retained in position until the filled composition has set, generally five minutes elapsing.
The shell 20 with the inner lining 22 now formed is subsequently trimmed to remove any excess filler material particularly gathered around the fence 60. The connecting web 62 may be then removed. Now the mouthpiece 10 is formed and ready for use.
It should be noted that the filler composition of the invention may be utilized as a repair mixture in the event that future repairs are required.
It is believed that the invention has been described in sufficient detail to permit the skilled artisan to practice same. It is believed that minor variations in the construction of the device and in the method of fitting and forming thereof without departing substantially from the concept and scope of the invention as defined in the appended claims.
