Disclosed is dental gum for cats, characterized in that. At this time, it is preferable that the dental gum for cats is made of a porous material so that the surface can be scratched while the teeth are embedded without breaking it as it is partially damaged and compressed while having hardness, and the surface is distributed with concave or trough parts that are easy for cat teeth to enter. No matter where the teeth are biting, the teeth are guided to the concave portion nearby, and the dental gum for cats ruptures in the concave portion, making the tooth surface easier to scratch with the dental gum for cats.
The dental gum for cats of the present invention cannot be easily swallowed by cats, and by inducing a biting action, friction (scratches) can be easily made between the teeth and the material constituting the dental gum for cats, so it can serve to clean the cat's teeth. .

Description

dental gum for cats

The present invention relates to a dental gum for cats that can be used for dental health of a pet cat.

A pet's lifespan is highly dependent on dental health. Periodontal disease is one of the most common diseases in companion animals. It is known that 80% of dogs and 70% of cats after 2 years of age have various types of periodontal disease.

However, continuing to brush the teeth of a companion animal becomes cumbersome and difficult for both the animal and the owner. To solve this problem, dog gum is widely used for dogs. In many cases, dog gum is made by processing the skins or tough parts of edible animals to serve as both a toy and a snack, and in this process, it can play a role in strengthening the dog's teeth.

However, this type of dog gum cannot have a great effect on brushing teeth, so it is crushed in the process of biting and chewing with the dog's teeth. Dog gum has been developed and used.

Korean Patent Registration No. 10-1784056 discloses such a dog gum.

Recently, awareness of cats has been increasing, but compared to products for dogs, dental health products for cats have not been developed much. Therefore, cat gum that is manufactured a little smaller in shape and material similar to that of existing dog gum and applied to cats is sold and used in the market.

However, since dog gum is made for dogs, unlike dogs, cats with different number, roles, and shapes of teeth are completely carnivores, so it is difficult to effectively apply them because their chewing methods and mechanisms are different.

Therefore, in order to help the dental health of cats, a separate cat gum that sufficiently considers the number, shape, and role of the cat's teeth and the chewing method and mechanism thereof is required.

Republic of Korea Patent No. 10-1784056: Dental chewing gum for dogs Republic of Korea Patent No. 10-1069862: Manufacturing method of pet snacks for reducing tartar in pets

An object of the present invention is to provide a dental gum for cats that can solve the problem of providing the above-described conventional cat gum in the form of dog gum to cats and is effective in preventing periodontal disease in cats.

An object of the present invention is to provide a dental gum for cats in which the cat gum induces a biting and chewing motion without swallowing the cat, so that friction (scratches) can be easily made between the teeth and the material constituting the cat gum.

An object of the present invention is to provide a dental gum for cats that can be easily crushed and not slippery when a cat bites or chews so that the cat gum can be effectively scratched on the cat's teeth.

The dental gum for cats of the present invention for achieving the above object is made at least greater than or equal to 4.0 cm in the longitudinal direction and greater than or equal to 1.6 cm in the radial or width direction, making it difficult to swallow at a time due to the oral structure of most cats. It is characterized in that it is made to be chewed with teeth at least twice and divided into sizes suitable for swallowing.

In addition, in the present invention, the surface of the dental gum for cats is distributed with a concave part or a trough part where cat teeth easily enter, so that the teeth that bite any part are guided to the concave part in the vicinity thereof, and the dental gum for cats ruptures in the concave part. The tooth surface is made with dental gum for cats and easy to scratch.

In the present invention, a mountain part is formed together with the trough part, and the ridge part and the mountain part may be formed by coupling two or more rod-shaped parts to be twisted with each other like a twist.

In the present invention, the valley portion and the mountain portion may be formed so as to extend long in the longitudinal direction and alternately positioned throughout the entire circumferential direction.

At this time, the distance between the mountain and the mountain and the depth between the valley and the mountain are about 1/4 or more and 1/3 or less in diameter or width, and the slope between the mountain and the mountain may form a concave curve.

At this time, the slope has a large number of undulating projections, with a small concave portion between the projections and a small convex portion formed by the projections. It can be done well. Small concave parts and small convex parts may be installed regularly, but in the valley part and mountain part, convex projections like the surface of bitter gourd fruit may be scattered at irregular heights and intervals.

In this case, the size in the diameter or width direction may increase toward the central portion in the longitudinal direction to have a convex center and narrow ends at both ends.

In the present invention, the dental gum for cats is in the form of a cylinder or a round rod as a whole, and the troughs on the side form a linear groove in the longitudinal and circumferential or circumferential directions, but in the form of a grid with a constant or different spacing between the lines. can achieve In this case, the interior may be an empty space or may be filled.

The dental gum for cats of the present invention cannot be easily swallowed by a cat, and by inducing a biting action, friction (scratches) can be easily made between the teeth and the material constituting the dental gum for cats, so it can serve to clean the cat's teeth. .

In addition, the dental gum for cats of the present invention is not easily slippery and shredded when the cat bites, so that the cat's teeth enter into the cat's dental gum material so that the cat's dental gum is effectively scratched by the cat's teeth to easily clean the cat's teeth. It can serve as a cleaning agent.

Hereinafter, the present invention will be described in more detail through specific examples with reference to the drawings.

First, in order to form dental gum for cats that can perform the most suitable function of maintaining cat teeth health, the inventor first attempts to accurately identify and organize the cat's mouth and tooth size, shape, and cat's chewing behavior, and through this We tried to recognize the characteristics that dental gum should have.

First, in order to understand the size, shape, and structure of the cat's mouth and teeth, DKSH (domestic Korean short hair cat) 1 neutered female (FS) and 3 neutered males (MC) aged 1 to 10 years old, Russian blue cat (Russian blue cat) The test is conducted on one 4-year-old neutered male.

As a pre-step to measure the calculus removal effect of dental gum for cats, these cats were scaled under anesthesia to clean their oral cavity.

The size of each tooth is measured with a digital caliper. The maxilla is the height of the second premolar (premolar:PM), the height of the maxillary third premolar, the length between the maxillary premolars, and the mandible (mandible). ) height of first premolar, height of mandibular second premolar, height of first and second tip of mandibular molar (molar:M), length between mandibular premolar, mandibular second premolar and first molar The length between the ends or tips, and the length between the first and second tips of the mandibular molars were measured.

And for one separate target cat, using Alginate (trade name) and yellow stone (trade name), one upper and lower oral structure model or model frame (frame like plaster mold) was made to represent the size of the oral cavity of the maxilla and mandible. Possible sizes, such as length C between canine teeth, length A between innermost molars, and length B between the inner side of the incisor and innermost molars, were measured using a digital caliper.

In addition, the mastication time and mastication method were analyzed by photographing and observing the appearance of the cat chewing from the side and the front in order to grasp the chewing movement or chewing behavior.

1 and 2 are plan photos of the maxillary model frame and mandibular model obtained in this way, FIGS. 3 and 4 are isometric photos of the maxillary model frame and mandibular model obtained in this way, and FIG. 5 is the maxillary frame and mandible. It is a side view showing the meshing state of the frame.

Here, Cr denotes the anterior tip of the molars (Cranial tip of the teeth), Cd denotes the caudal tip of the teeth, PM denotes the anterior teeth, M denotes the molars, and Maxilla denotes the maxilla and Mandible denotes the mandible.

When comparing and analyzing each part of the cat's oral structure, looking at the numerical values obtained through the above examination mainly with important values, A, which corresponds to the maximum horizontal width of the maxilla, is 38.3±3.38 mm, and B, which corresponds to the maximum vertical length of the maxilla, is 36.2. It was measured to be ±3,346mm, mandibular A was measured to be 32.52±1.92mm, and B was measured to be 32.34±1.61mm. The maxillary and mandibular A/B ratios are 1.06 and 1.005.

If it is larger than one of A and B, it cannot be put in the mouth at once and swallowed, so if it is considered as the largest, it is greater than 41.68, and in terms of the statistical average, it is greater than 38.3. Therefore, if the length of the object, such as food, is formed larger than this length, the object is rarely swallowed without chewing.

As a mastication-related chewing tooth, the height of the premolar and posterior teeth was measured. As a result, the height of the mandibular second premolar (PM2) was measured to be the lowest at 4.08±0.37mm, and the height of the maxillary third premolar (PM3) was 4.83±0.68mm. was measured to be the highest. As for the width, the lower first molar was measured at 2.08±0.045mm, and the third premolar of the maxilla was measured the highest at 2.18±0.057mm.

Cat's teeth (Type of teeth) are 3/1/3/1 of the maxilla and 3/1/2/1 of the mandible, with 3 anterior teeth, 1 canine, and 1 molar, and only the front teeth have one more maxilla. However, the first anterior and posterior teeth of the maxilla are small in size and have little relation to the occlusion of the mandibular anterior and posterior teeth.

Not only the canine, but also all the anterior and posterior teeth have very sharp ends, so it can be seen that the tip (tips) of the upper and lower teeth do not meet each other and occlude when viewed from the side when the upper and lower teeth meet.

The main occlusal part related to mastication is the part where the maxillary second and third anterior teeth, and all the anterior and posterior teeth of the mandible are located, as shown by the arrow in Fig. It is the length of the section where the molars are located.

As the length between masticatory teeth, the length between the maxillary 2nd and 3rd anterior teeth is 8.46±0.55mm, the length between the mandibular 2nd and 3rd anterior teeth is 7.1±0.652mm, and the 3rd premolar is 8.46±0.55mm. The length to the anterior tip of the and molars was measured to be 4.2±0.447mm, and the length between the anterior and posterior tips of the posterior teeth was measured to be 5.4±0.652mm, and the total occlusal length was measured to be 16mm, more precisely, 16.7±0.583mm. became

After biting an object such as food with an incisor and putting most of it into the mouth, if the length or width is large, it is difficult to swallow and chews with chewing teeth, and the object is located in the middle of the chewing teeth. Of course, even if the object is long enough that it cannot be put into the mouth in one bite, hold or press part of it with your hands, and then bite the tooth so that the teeth and the length of the food cross on the chewing tooth side, and then cut it off or break the tip and chew it and then swallow it. .

In this case, if the dental gum is larger than the total occlusal value, most of these teeth come into contact with the dental gum when masticating with the molars and anterior teeth. It can serve to scratch the surface.

Therefore, if the dental gum has a width or diameter greater than 16 mm, more preferably 16.7 mm, corresponding to the total occlusal length, almost all of the chewing teeth are placed in the middle of the total occlusal area and chewed. It is inserted into the main body of the body and serves to wipe the teeth, so it is preferable for cleaning teeth.

On the other hand, PM3, which has the largest vertical length or height (H) of the maxilla in masticatory teeth, is 4.83 mm, and the second tip of the molars, which has the largest vertical length or height (H) of the mandible, is 4.8 mm. , simply adding them does not exceed 10mm, and in general, these ends do not meet each other and are in contact with each other in the interlocking state. , there is no big problem even if the height of the teeth is not considered in determining the width or diameter of the dental gum. That is, the total length of the occlusal part is usually considerably longer than the length from the root of the upper tooth to the root of the lower tooth during bite, and therefore the thickness (width) or diameter is large enough to insert the tooth to the root when chewing. is not required as a separate size condition.

As a result of analyzing the chewing mechanism through the photographed data, the cat first grabs the food with the anterior teeth and transfers it directly to the anterior and posterior teeth (total occlusal part) to perform the masticatory movement. Usually, the number of mastications is 3 to 7 times, and the material and size of the food. There is a difference in the number of times. In particular, in the first work, the object is broken or cut with a strong force, and subsequent works become auxiliary works. The incisors and canines are rarely used in the work. The incisor mainly plays a role in catching objects such as prey, while the canine teeth kill or tear the prey, but play no special role in mastication. All teeth are made to eat with minimal chewing movement and little chewing as a whole.

If we summarize the oral size and tooth arrangement, shape, size and chewing behavior of cats as described above, there is no significant difference in the size of the oral cavity in cats over 1 year old, so prepare various sizes when making dental gum for cats. Rather than that, it is preferable to prepare a cat gum of a common size for all cats over 2 years of age in which dental disease (periodontal disease) is a problem, and it means that a commonly desirable dental gum size can be determined.

In addition, dental gum for cats is a carnivore, and when a cat is chewing food, the front and molars have a sharp tip similar to the canine of a normal animal, and are sharply formed like a scissors blade, so it cuts food only a small number of times. Considering that chewing and swallowing small lumps, dental gum for plaque or tartar removal is based on the largest size among maxilla and mandible A and B, which indicates the size of the mouth in relation to the size of the oral cavity. In order to ensure sufficient chewing time without swallowing, each should be formed larger than the length, and it is appropriate to set the length to 40mm or more, and the width or diameter to be 16.7mm or more.

However, if it exceeds these sizes, there is no problem with swallowing, and there is no need to make it too large beyond these values because it can come into contact with all of the chewing teeth during mastication. If the length is too large, the cat may lose it while eating or chewing, and if the width or diameter is too large, it may cause discomfort in the cat having to open its mouth to chew dental gum. Therefore, it is desirable to form a width of 80 mm or less and a width of 20 mm or less.

On the other hand, if you look at the feeding and chewing behavior of cats, the contact between the dry food and the teeth is mainly made at the tooth end (tip), and even in the case of small pieces of food containing a lot of carbohydrates or polysaccharides, they are often swallowed without chewing as they are given.

When examining the effect of giving cats various types of dry food and wiping the tooth surface after tooth cleaning to remove existing tartar or plaque, group 1 with materials capable of mechanical cleaning or small food, and small food with little mechanical cleaning action When an experiment was conducted with group 2, in which the owner had to brush teeth, group 3, which was given a large feed made of a material capable of mechanical cleaning, and group 4, which was fed the same food as group 2 but did not brush their teeth, Group 3 fed the diet had less gingivitis, plaque, and calculus.

Materials that can be cleaned are mainly hard, but partially brittle foods due to porosity (multipore), which can prevent the teeth from completely splitting until they are completely embedded in the food, or completely In order to prevent splitting, the inside is woven with fibers or the like.

These materials are also relatively dry and hard to maintain their shape, so even if they are the same size, they do not pass through the throat as well as soft foods such as meat, so the number of times of chewing increases naturally and the possibility of swallowing is reduced, which is advantageous for cleaning teeth.

In other words, cat dental gum is made of a soft material that cannot be swallowed even in large chunks, it is made of a hard material that maintains its shape, and a hard material that can scratch the tooth surface with sufficient mechanical strength. Rather than cracking or crushing even a small amount of teeth when chewing or chewing, the entire or substantial part of the tooth is embedded in the body and made porous so that it can contact the tooth surface, or fibrous tissue that is tougher than the grain body, such as the fibrous tissue of fish meat, It is desirable to make cat dental gum from a material that combines the same fibrous tissue as the loofah's fibrous tissue and gives it a chance to chew several times because it is not easily cut once bitten.

On the other hand, to verify the effect of dental gum, the experimental group was divided into a case where only dry feed was given and a case where dental gum was given after a certain period of time, such as 3 hours, after feeding dry feed. As a result, gingivitis, plaque, Dental gum appears to be effective in calculus, and in particular, in periodontal diseases or problems that can be affected by scratching, such as tartar, it is shown to be effective in preventing periodontal disease by showing an improvement effect of about 64%.

If we have mainly looked at the size and material aspects of dental gum for cats above, we will look at the specific appearance and shape of some dental gums for cats below.

In the case of cats, chewing teeth like premolars (premolars) and molars (molars) also have sharp and pointed ends, so it can be considered that there is almost no grinding friction surface on the top like molars of herbivores. It is made through a scratching action while being embedded in the dental gum body, and in order for the teeth to stick to the body well, the body is made of a porous material, and the tooth tip is placed under force to prevent the teeth from sliding off the body surface when chewing. It would be better if I had a home.

Several types of dental gum are proposed as a way to create gaps or grooves to support the ends of these teeth and are explained through drawings. 6 to 8 are conceptual perspective views of embodiments showing several different forms of the dental gum of the present invention.

6 discloses a dental gum in the form of a cylindrical pellet. At this time, the lattice line grooves in the horizontal and vertical directions are formed on the side surface of the cylinder.

If you look at the overall size, the length is 40mm and the diameter is 16mm, and the material is made of a relatively hard material such as dry food or sweets. It is made of a porous material so as not to be crushed.

In dental gum that has a round and smooth surface, if the tooth tip (tip) gets caught in these grid grooves, it does not slide easily, and when a cat chews, sufficient force is applied to the dental gum and the tooth is easily embedded into the body.

The entrance width and depth of the groove is about 2mm, which is made up of the tip of the cat's anterior and posterior teeth with a sharp tip, and the tooth width is also slightly larger than about 2mm. Because. The depth of the groove should be sufficiently small compared to the height of the tooth so that the tooth can be driven deeper into the body from the groove.

The spacing between the linear grooves parallel to each other can be determined by considering the spacing between the cat's chewing teeth or the spacing between the tips. For example, the average distance between the tips of the 2nd and 3rd anterior teeth, which are masticatory teeth in the maxilla in cats, is 8.46 mm on average, and between the tips of the 2nd anterior premolar and the 1st tip of the molar, the two tips in the middle of the total occlusal part of the mandible. Since the distance of is 4.2mm, if the groove and groove are formed periodically so that the gap is approximately 4.2mm, the two tips of the mandible are caught in the groove at the same time, and the distance between the tips of the two teeth of the upper jaw is close to twice that, so the probability of getting caught in the groove at the same time this rises

Similarly, the distance between the tip of the first and second premolars of the mandible is 7.5mm, and the distance between the first and second tips of the mandibular molars is 5mm. Therefore, as a common factor, grooves are made at intervals of 2.5mm, which is a common interval. Formation may increase the probability that the groove will catch on the tip of the first and second premolars of the mandible at the same time, or on the first and second tips of the mandibular molars at the same time.

However, in this embodiment, since the groove is formed on the side surface of the cylindrical ferret, it may be necessary to form it at a slightly wider interval than the interval of a straight line concept.

7 discloses a dental gum in which the diameter in the middle of the length is large and the diameter at both ends of the length is reduced in the form of a convex column in the middle, and the side surface is formed by alternating valleys and mountains in the circumferential direction.

Macroscopically, apart from the formation of valleys and mountains in the circumferential direction on the lateral surface, microscopically, a large number of small protrusions with a height of 2 mm and a tip spacing of 2 mm are distributed throughout the lateral surface.

Again, looking at the overall size, the length is 40mm and the diameter is 16mm, and the material is made of a relatively hard material such as dry feed or sweets. It is made of a porous material so as not to split.

The reason for changing the diameter in the longitudinal direction here is that the diameter is different for each part, and the cat chews dental gum while placing the diameter part of the appropriate size on the occlusal part of the teeth, that is, chewing it and cutting it in the longitudinal direction. , The cut part is put in the mouth and has an opportunity to chew again, and the convex part in the middle is formed with a width or diameter of 16mm or more. The action of cleaning the teeth by touching can be made.

At this time, the convex center and the small diameter at both ends allow the cat to easily insert the dental gum into the oral cavity at the stage of putting the dental gum into the mouth for the first time.

Since a number of protrusions are evenly distributed on the surface, the tip is placed between the protrusions of the chewing tooth when the tips of the masticating tooth come into contact with any part, and the tooth tip does not slide even on the slope between the bone and the mountain, and pressure is applied to the dental gum body. This allows the teeth to be easily embedded in the body and scrape the teeth.

Therefore, there are many bumpy projections on the slope or bone between the mountains and the small concave part between the projections and the small convex part formed by the projections. can be embedded well into the body when chewed. Small concave parts and small convex parts may be installed regularly, but convex protrusions like the surface of bitter gourd may be scattered at irregular heights and intervals.

8 discloses a dental gum in a form in which a plurality of stems are twisted together and proceed in the longitudinal direction when long hair is braided in a twist shape. Here, three small-diameter pillars, for example, 8mm-diameter pillars, were twisted to form a groove between the pillars and the pillars. Here, the reason that the diameter of the column corresponding to the stem is 8 mm is in consideration of the distance between the chewing tooth tip and the adjacent tooth tip, and the same explanation as described in FIG. 7 can be applied.

Again, looking at the overall size, the length is 40mm and the diameter is 16mm, and the material is made of a relatively hard material such as dry feed or sweets. It should be made of a porous material so that it does not split, or it must be chewed several times without breaking easily, including fibers.

In the above, the present invention has been described with reference to limited embodiments, but these are only illustratively described to help the understanding of the present invention, and the present invention is not limited to these specific embodiments.

Accordingly, those of ordinary skill in the art to which the present invention pertains will be able to make various changes or application examples based on the present invention, and it is natural that such modifications or application examples belong to the appended claims.
