The dental typodont includes upper and lower animal jaw members having a gum section containing a plurality of spaced-apart recesses releasably receiving a corresponding plurality of teeth such as the incisor, molar and bicuspid teeth. The upper and lower jaw members simulate the jaws of a canine or feline, for example. The teeth are frictionally secured within the recesses. An interlock or thumbscrew mechanism is used to secure the jaws in an open or closed position.
Description
TITLE
Dental Typodont for Practicing the Art of Dentistry BACKGROUND OF THE INVENTION
The present invention relates generally to dental typodonts for practicing the art of dentistry and, more particularly, to non-human dental typodonts for permitting veterinarian dental students and veterinarians to practice and learn the art of veterinary dentistry.
To practice and learn the art of veterinary dentistry, veterinarian dental students and veterinarian dentists typically utilize the skull of an animal cadaver.
However, animal cadavers are impracticable and disadvantageous for several reasons.
Animal cadavers typically must be stored under cold conditions, such as in a freezer, to preserve the cadavers, and further must be transported in coolers or the like.
In addition, animal cadavers often emit a foul-smelling odor, so that veterinarian dental students must contend with the unpleasant odor when utilizing the cadavers.
Further, in practicing the art of veterinary dentistry, it is often advantageous to remove each individual tooth of the cadaver for further examination. However, animal cadaver teeth are naturally firm and secured to the jaw members so that the teeth are not easily removable and re-insertable. Even where the foregoing disadvantages are overcome, in some cases, veterinarian dental students encounter difficulty in procuring these cadavers for use in part because of their relatively high cost and the limited supply of the cadavers. Additionally, unnecessary effort is often expended in preparing the cadavers and chemicals must be procured to preserve the cadavers for future use.
Consequently, animal cadavers offer limited benefits to both veterinarian dental students and veterinarian dentists as a learning or a practice tool.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, the present invention relates to a dental typodont for practicing the art of veterinary dentistry. The dental typodont includes a first non-human jaw member having a gum section containing a plurality of spaced-apart recesses releasably receiving a corresponding plurality of teeth. Each tooth has a root portion and an exposed portion. The root portion is removably seated in one of the corresponding recesses and the exposed portion extends outwardly from the gum section.
In another aspect, the present invention relates to an artificial non-human tooth utilized by dental students for practicing the art of veterinary dentistry.
The non-human tooth is constructed of an artificial material and includes a root portion and an exposed portion. The root portion is for being removably seated in a corresponding recess and the exposed portion extends outwardly from a gum section in which the corresponding recess is formed.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
The foregoing summary, as well as the following detailed description, will be better understood when read in conjunction with the appended drawings.
For the purpose of illustrating the invention there are shown embodiments which are presently preferred, it being understood, however, that this invention is not limited to the precise arrangement and instrumentalities shown. In the drawings:
FIG. 1 is a front perspective view of a dental typodont in accordance with a first embodiment of the present invention;
FIG. 2 is a partially exploded left side elevational view of the dental typodont shown in FIG. 1 in the open position;
FIG. 3 is a rear perspective view of a dental typodont in accordance with a second embodiment of the present invention; and FIG. 4 is a right side elevational view of the dental typodont shown in FIG. 3 in the open position.
DETAILED DESCRIPTION OF THE INVENTION
Certain terminology is used in the following description for convenience only and is not limiting. The words "right," "left," "lower," and "upper"
designate direction in the drawings to which reference is made. The words "inwardly" and "outwardly" refer to directions toward and away from, respectively, the geometric center of the dental typodont and designated parts thereof. The terminology includes the words above specifically mentioned, derivatives thereof and words of similar import. As used herein, the word "a" as used in the claims means "at least one."
Referring now to the drawings in detail, wherein like numerals indicate like elements throughout, there is showing in FIG. 1 a first dental typodont 10 for practicing the art of dentistry in accordance with a first embodiment of the present invention. More specifically, the dental typodont 10 simulates the jaw members of a feline.
The dental typodont 10 includes a first or lower non-human jaw member 12 having a gum section 14 containing a plurality of spaced apart recesses 16 releasably receiving a corresponding plurality of teeth 18. The gum section 14 of the lower jaw member 12 is constructed of a soft and durable gum-simulating material. It is preferred that the soft and durable gum-stimulating material be vinyl.
However, it is understood by those of ordinary skill in the art from this disclosure that the soft and durable gum simulating material could be other materials, such as thermoset or I S thermoplastic without departing from the spirit and scope of the invention. The gum section 14 is preferably formed by a molding process well understood by those of ordinary skill in the art in the dental typodont industry. Accordingly, further description of the exact molding process for forming the gum section 14 is omitted for purposes of convenience only and is not limiting.
The gum section 14 can be of a two-part construction (not shown). That is, positioned on top of the vinyl gum section 14 can be a replaceable upper softer gum section preferably mode from a soft gum simulating material, such as a polyvinyl chloride blend. In this manner, if a student damages an upper gum section during a lab session, the upper gum section can be replaced without having to replace the entire lower jaw member 12.
The recesses 16 are formed in the gum section 14 during the molding process. However, it is understood by those of ordinary skill in the art that the recesses 16 could be machined into the gum section 14 subsequent to the molding process without departing from the spirit and scope of the invention. Additionally, the dental typodont 10 includes a second or upper non-human jaw member 24 secured to the lower non-human jaw member 12. As discussed with reference to the lower jaw member 12, the upper jaw member 24 similarly includes a gum section containing a plurality of spaced apart recesses 16 releasably receiving a corresponding plurality of teeth 18. The upper jaw member 24 is constructed of the same material and in the same manner as the lower jaw member 12. In the present embodiment, although the lower and upper jaw members 12, 24 simulate the natural upper and lower jaws of a feline, it is understood by those of ordinary skill in the art from this disclosure that the jaw members 12, 24 may simulate the natural upper and lower jaws of any animal without departing from the spirit and scope of this invention. A flat portion 54 parallel to the axis of the lower jaw member 12 enables placing of the dental typodont 10 on a flat horizontal surface.
The second or upper jaw member 24 is pivotally secured to the first or lower jaw member 12 so that the jaw members 12 and 24 move between an open position (FIG. 2) and a closed position (FIG. 1). When open, the lower and upper jaw members 12 and 24 are spaced from each other (see FIG. 2) and when closed are in engagement with each other (see FIG. 1).
An interlock 30 which is located between the lower and upper jaw members 12 and 24 releasably interlocks the jaw members 12 and 24 in the open position. The interlock 30 includes a rod 34, a handle 36, and a hinge 32. The rod 34 includes a proximal portion 52 which is fixedly attached to the handle 36 and a distal portion 60 which is externally threaded. The hinge 32 includes an upper portion or generally T-shaped member 32A and a lower portion or generally U-shaped member 32B. The T-shaped member 32A is fixedly attached to the upper jaw member 24 by fitting the T-shaped member into a similarly sized T-shaped cavity 58 (located behind the upper jaw member 24). Thereafter, the T-shaped member 32A is fastened to the cavity 58 of the upper jaw member 24 by using a fastener, such as, a screw 31 a (FIG.
2) or the like. 'the U-shaped member 32B is similarly integrated into a U-shaped cavity 60 located behind the lower jaw member 12. After the U-shaped member 32B is integrated, it is fastened to the lower jaw member 24 using a fastener, such as a screw 31b (FIG. 2) or the like. Thereafter, the T-shaped and U-shaped members 32A
and 32B are pivotally attached using the interlock 30 as follows.
The U-shaped member 32B has a first bore 40 through its proximal arm 44 and a second bore 42 through its distal arm 46. While the first bore 40 is unthreaded, the second bore 42 is threaded to engage the corresponding external thread on the distal portion 60 of the rod 34. Similarly, the T-shaped member 32A has a non-threaded bore 48 through its vertical arm 50. A user inserts the vertical arm 50 of the T-shaped member 32A into a recess 62 located between the proximal and distal arms 44 and 46 of the U-shaped member 32B. The T-shaped member 32A is inserted such that the first bore 40 of the proximal arm 44 (of the U-shaped member 32B) is aligned with both the non-threaded bore 48 of the vertical arm 50 (of the T-shaped member 32A) and the second bore 42 of the distal arm 46 (of the U-shaped member 32B).
Thereafter, the rod 34 is inserted through the first bore 40, followed by the non-threaded bore 48, until the rod 34 is in contact with the second bore 42.
After contact is made, the user begins to rotate the handle 36 in a clockwise direction until the externally threaded distal portion 60 of the rod 34 engages the internally threaded second bore 42 of the U-shaped member 328. The user continues to rotate the handle 36 until the distal portion 60 has sufficiently engaged the second bore 42, so that the upper and lower jaws 12 and 24 are pivotally attached, and are rotatable around the rod 34 in an open or close position.
The jaw members 12 and 24 can be locked in a designated position by continuously rotating the handle 36 in the clockwise direction until the rod 34 is no longer rotatable. The jaw members 12 and 24 are locked in a designated position since the proximal portion 52 of the rod 34 has a larger diameter relative to the first bore 40 of the proximal arm 44 of the U-shaped member 32B. This enables the proximal portion 52 to engage and compress the wall around the first bore 40 of the proximal arm 44. In turn, the proximal arm 44 compresses the vertical arm 50 of the T-shaped member 32A, which in turn compresses the distal arm 46 of the U-shaped member 32B, so that the vertical arm 50 is locked in the designated position. That is, the vertical arm 50 is held immobile by the proximal and distal arms 44 and 46.
While it is preferred that the lower and upper jaw members 12 and 24 be pivotally secured together, it is understood by those of ordinary skill in the art from this disclosure that the jaw members 12 and 24 could be permanently mounted in the open position (not shown).
Referring now to FIG. 2, each tooth 18 has a root portion 20 and an exposed portion 22. When the root portion 20 is removably seated within one of the corresponding recesses 16, the exposed portion 20 extends outwardly from the gum section 14. The recesses 16 are tapered to receive the root portion 20 which is similarly tapered to fit snugly into the corresponding recesses 16. It is preferred that teeth 18 and recesses 16 be sized such that the teeth 18 are fractionally secured within the recesses 16. 'the teeth 18 may be removed by firmly tugging on the exposed portion 22 and is reinsertable by applying an upward or downward force on the exposed portion 22 to secure the teeth 18 into place. Although not shown, various I S mechanisms known in the art may be utilized for releasably or fixedly securing the teeth 18 in position including adhesives, binding rings, or the like. The teeth 18 simulate natural teeth found in a feline including the incisor, molar and bicuspid teeth.
The teeth 18 are preferably made of an artificial material which simulates the characteristics of natural teeth, such as Ivorine/Cymel, manufactured by AC
Molding Co. of Wallingford, Connecticut. It is understood by one of ordinary skill in the art from this disclosure that the teeth 18 could be made from any material that is deemed appropriate. For example, the teeth could be made out of thermoset or thermoplastic without departing from the spirit and scope of the invention.
It is understood by those of ordinary skill in the art that dental typodonts are typically used with mannequins to locate the typodont in a position which corresponds to the position of natural use during dentistry. In the veterinary field, the subject is anesthetized for a dental procedure. It is within the present invention to include a releasable mount (not shown) on the typodont 10 to secure the typodont 10 to a mannequin. For instance, such a mount could be located on the back surface of the upperjaw 24.
In use, a veterinarian dental student unlocks the interlock 30 by rotating the handle 36 (FIG. 1) in an counterclockwise direction to release the lower and upper jaw members 12 and 24. Next, the lower and upper jaw members 12 and 24 are opened, preferably, so that the lower and the upper jaw members 12 and 24 are generally perpendicular to each other (FIG. 2). Thereafter, the handle 36 is rotated clockwise to lock the jaw members 12 and 24 in the open position. To examine a tooth 18 more closely, the veterinarian dental student may remove the tooth 18 by firmly tugging on the exposed portion 22, and reinserting the tooth 18 by applying an upward or downward force on the exposed portion 22. When removably in place, each tooth 18 may be operated upon in the same manner as would be in actual dental practice.
Such operations include without limitation, drilling, replacing of teeth, and the like.
Similarly, by following the procedure for use as discussed above, veterinarian dentists can use the present invention for demonstrating a dental procedure or for illustrating a dental problem to feline and canine owners.
The foregoing summary, as well as the following detailed description, will be better understood when read in conjunction with the appended drawings.
For the purpose of illustrating the invention there are shown embodiments which are presently preferred, it being understood, however, that this invention is not limited to the precise arrangement and instrumentalities shown. In the drawings:
FIG. 1 is a front perspective view of a dental typodont in accordance with a first embodiment of the present invention;
FIG. 2 is a partially exploded left side elevational view of the dental typodont shown in FIG. 1 in the open position;
FIG. 3 is a rear perspective view of a dental typodont in accordance with a second embodiment of the present invention; and FIG. 4 is a right side elevational view of the dental typodont shown in FIG. 3 in the open position.
DETAILED DESCRIPTION OF THE INVENTION
Certain terminology is used in the following description for convenience only and is not limiting. The words "right," "left," "lower," and "upper"
designate direction in the drawings to which reference is made. The words "inwardly" and "outwardly" refer to directions toward and away from, respectively, the geometric center of the dental typodont and designated parts thereof. The terminology includes the words above specifically mentioned, derivatives thereof and words of similar import. As used herein, the word "a" as used in the claims means "at least one."
Referring now to the drawings in detail, wherein like numerals indicate like elements throughout, there is showing in FIG. 1 a first dental typodont 10 for practicing the art of dentistry in accordance with a first embodiment of the present invention. More specifically, the dental typodont 10 simulates the jaw members of a feline.
The dental typodont 10 includes a first or lower non-human jaw member 12 having a gum section 14 containing a plurality of spaced apart recesses 16 releasably receiving a corresponding plurality of teeth 18. The gum section 14 of the lower jaw member 12 is constructed of a soft and durable gum-simulating material. It is preferred that the soft and durable gum-stimulating material be vinyl.
However, it is understood by those of ordinary skill in the art from this disclosure that the soft and durable gum simulating material could be other materials, such as thermoset or I S thermoplastic without departing from the spirit and scope of the invention. The gum section 14 is preferably formed by a molding process well understood by those of ordinary skill in the art in the dental typodont industry. Accordingly, further description of the exact molding process for forming the gum section 14 is omitted for purposes of convenience only and is not limiting.
The gum section 14 can be of a two-part construction (not shown). That is, positioned on top of the vinyl gum section 14 can be a replaceable upper softer gum section preferably mode from a soft gum simulating material, such as a polyvinyl chloride blend. In this manner, if a student damages an upper gum section during a lab session, the upper gum section can be replaced without having to replace the entire lower jaw member 12.
The recesses 16 are formed in the gum section 14 during the molding process. However, it is understood by those of ordinary skill in the art that the recesses 16 could be machined into the gum section 14 subsequent to the molding process without departing from the spirit and scope of the invention. Additionally, the dental typodont 10 includes a second or upper non-human jaw member 24 secured to the lower non-human jaw member 12. As discussed with reference to the lower jaw member 12, the upper jaw member 24 similarly includes a gum section containing a plurality of spaced apart recesses 16 releasably receiving a corresponding plurality of teeth 18. The upper jaw member 24 is constructed of the same material and in the same manner as the lower jaw member 12. In the present embodiment, although the lower and upper jaw members 12, 24 simulate the natural upper and lower jaws of a feline, it is understood by those of ordinary skill in the art from this disclosure that the jaw members 12, 24 may simulate the natural upper and lower jaws of any animal without departing from the spirit and scope of this invention. A flat portion 54 parallel to the axis of the lower jaw member 12 enables placing of the dental typodont 10 on a flat horizontal surface.
The second or upper jaw member 24 is pivotally secured to the first or lower jaw member 12 so that the jaw members 12 and 24 move between an open position (FIG. 2) and a closed position (FIG. 1). When open, the lower and upper jaw members 12 and 24 are spaced from each other (see FIG. 2) and when closed are in engagement with each other (see FIG. 1).
An interlock 30 which is located between the lower and upper jaw members 12 and 24 releasably interlocks the jaw members 12 and 24 in the open position. The interlock 30 includes a rod 34, a handle 36, and a hinge 32. The rod 34 includes a proximal portion 52 which is fixedly attached to the handle 36 and a distal portion 60 which is externally threaded. The hinge 32 includes an upper portion or generally T-shaped member 32A and a lower portion or generally U-shaped member 32B. The T-shaped member 32A is fixedly attached to the upper jaw member 24 by fitting the T-shaped member into a similarly sized T-shaped cavity 58 (located behind the upper jaw member 24). Thereafter, the T-shaped member 32A is fastened to the cavity 58 of the upper jaw member 24 by using a fastener, such as, a screw 31 a (FIG.
2) or the like. 'the U-shaped member 32B is similarly integrated into a U-shaped cavity 60 located behind the lower jaw member 12. After the U-shaped member 32B is integrated, it is fastened to the lower jaw member 24 using a fastener, such as a screw 31b (FIG. 2) or the like. Thereafter, the T-shaped and U-shaped members 32A
and 32B are pivotally attached using the interlock 30 as follows.
The U-shaped member 32B has a first bore 40 through its proximal arm 44 and a second bore 42 through its distal arm 46. While the first bore 40 is unthreaded, the second bore 42 is threaded to engage the corresponding external thread on the distal portion 60 of the rod 34. Similarly, the T-shaped member 32A has a non-threaded bore 48 through its vertical arm 50. A user inserts the vertical arm 50 of the T-shaped member 32A into a recess 62 located between the proximal and distal arms 44 and 46 of the U-shaped member 32B. The T-shaped member 32A is inserted such that the first bore 40 of the proximal arm 44 (of the U-shaped member 32B) is aligned with both the non-threaded bore 48 of the vertical arm 50 (of the T-shaped member 32A) and the second bore 42 of the distal arm 46 (of the U-shaped member 32B).
Thereafter, the rod 34 is inserted through the first bore 40, followed by the non-threaded bore 48, until the rod 34 is in contact with the second bore 42.
After contact is made, the user begins to rotate the handle 36 in a clockwise direction until the externally threaded distal portion 60 of the rod 34 engages the internally threaded second bore 42 of the U-shaped member 328. The user continues to rotate the handle 36 until the distal portion 60 has sufficiently engaged the second bore 42, so that the upper and lower jaws 12 and 24 are pivotally attached, and are rotatable around the rod 34 in an open or close position.
The jaw members 12 and 24 can be locked in a designated position by continuously rotating the handle 36 in the clockwise direction until the rod 34 is no longer rotatable. The jaw members 12 and 24 are locked in a designated position since the proximal portion 52 of the rod 34 has a larger diameter relative to the first bore 40 of the proximal arm 44 of the U-shaped member 32B. This enables the proximal portion 52 to engage and compress the wall around the first bore 40 of the proximal arm 44. In turn, the proximal arm 44 compresses the vertical arm 50 of the T-shaped member 32A, which in turn compresses the distal arm 46 of the U-shaped member 32B, so that the vertical arm 50 is locked in the designated position. That is, the vertical arm 50 is held immobile by the proximal and distal arms 44 and 46.
While it is preferred that the lower and upper jaw members 12 and 24 be pivotally secured together, it is understood by those of ordinary skill in the art from this disclosure that the jaw members 12 and 24 could be permanently mounted in the open position (not shown).
Referring now to FIG. 2, each tooth 18 has a root portion 20 and an exposed portion 22. When the root portion 20 is removably seated within one of the corresponding recesses 16, the exposed portion 20 extends outwardly from the gum section 14. The recesses 16 are tapered to receive the root portion 20 which is similarly tapered to fit snugly into the corresponding recesses 16. It is preferred that teeth 18 and recesses 16 be sized such that the teeth 18 are fractionally secured within the recesses 16. 'the teeth 18 may be removed by firmly tugging on the exposed portion 22 and is reinsertable by applying an upward or downward force on the exposed portion 22 to secure the teeth 18 into place.

Such operations include without limitation, drilling, replacing of teeth, and the like.
Similarly, by following the procedure for use as discussed above, veterinarian dentists can use the present invention for demonstrating a dental procedure or for illustrating a dental problem to feline and canine owners.
F1GS. 3 and 4 show a second dental typodont I 10 in accordance with a second embodiment of the present invention. More specifically, the second dental typodont 110 as illustrated simulates jaw members of a canine in a closed position.
The second dental typodont 1 10 is generally identical to the first dental typodont 10, except it is in the form of a canine and the interlock is different.
Accordingly, only the differences between the first and second typodont 10, 110 are described hereinafter.
Element numerals having a "100" prefix have been used for like elements, without a repeat of the description thereof.
A flat proximal end 142 of the upper jaw member 124 is fixedly attached to an upper curved bar 144 using a fastener such as, a screw 152 for example.
A lower curved bar 146 is fixedly secured to a proximal end 148 of the lower jaw member 112 by similarly using a fastener, such as a screw 158. Thereafter, a thumbscrew 150 is utilized to pivotally attach the terminal end of the upper curved bar 144 to the lower curved bar 146. The thumbscrew I 50 pivotally attaches the lower and upper curved bars 144 and 146 so that the lower and upper jaw members 112 and are rotatable around the thumbscrew 150 and can be locked in an opened or closed position (see FIG. 4). Also, the jaw members 112 and 124 are detachable by unscrewing the thumbscrew I50 until the jaw members 112 and 124 have been completely detached.
