Description

Composition for 3D printing and dental gum for pets manufactured using the same {COMPOSITION FOR 3D PRINTING AND DENTAL GUM FOR PETS MANUFACTURED USING THE SAME}

The present invention relates to a composition for three-dimensional printing and dental gum for companion animals manufactured using the same.

The mouths of companion animals, especially dogs and cats, actually function not only as an entrance to the digestive system. They use the mouth itself as a function to savor the world.

In other words, the mouth is used to play, the tongue is used to investigate the surrounding world, and excess heat is removed by panting. As a result, a wide variety of clinical diseases affecting pets' mouths, especially their teeth, are occurring.

In addition, because they prefer that the food provided to them is easy to feed, they do not provide pets with food that requires tearing or chewing, which worsens dental disease. In particular, soft food is fed to small dogs and cats. Additionally, because they tend to chew less than larger dogs, they produce more plaque than larger dogs.

Meanwhile, among dental diseases, it is assumed that plaque is generally caused by microscopic food residues, microorganisms, epithelial cells, etc., first depositing on the surface of the teeth, and then lime being deposited there. The structure of this plaque can be divided into a relatively soft part and a hard part. The part outside the edge of the gingiva (gum) is soft, and the part attached to the root surface below the edge of the tooth is hard.

Its composition is mainly calcium phosphate, and these plaques not only cause local causes such as gingivitis, pyorrhea, and bad breath, but also eventually cause the gums to melt due to inflammation, resulting in the need for surgery. Therefore, you must maintain the health of your teeth and gums by brushing your teeth after meals and massaging your gums regularly to prevent further plaque build-up. In addition, to maintain healthy teeth, you must maintain the cleanliness of the oral cavity by having veterinary plaque removed about twice a year.

However, since animals do not enjoy brushing their teeth, it is difficult to follow these daily rules, and scaling to remove plaque takes a lot of money and time.

Meanwhile, a representative example of gum or toys for preventing dental disease in companion animals is (Patent Document 1). The above (Patent Document 1) allows dogs or other carnivores to prevent dental disease by inducing chewing activity using their teeth.

That is, the above (Patent Document 1) includes an elastomer structure with at least one groove formed to remove plaque from the teeth and gums of the pet, so that the pet chews while playing with the teeth. Plaque on the teeth and gums is removed by the groove.

also. In the above (Patent Document 1), a hole is formed in the center of the elastomer structure to expand and contract as a whole, so that the outer wall of the groove scratches the teeth and gums during the pet's chewing process to remove plaque.

However, the chewing gum or toy for pets to prevent dental disease according to this (Patent Document 1) has the following problems.

First, the elastomer structure, which is a polymer compound, has no palatability at all. Therefore, the pet's interest level is low, so it becomes a toy to play with even if it is placed nearby. In this case, the pet may play with the material by moving it with its paws or teeth, but it will not chew with a grip strong enough to remove plaque, or in the worst case, it will play with the material. There is a problem that it is difficult to expect the effect because people are not even interested in it.

To solve this problem, you can scent the elastomer structure with spices to cover up the rubber smell and increase palatability, apply or coat a material with high palatability to the exterior or grooves, or embed it into the structure.

However, due to the animal's excellent olfactory discrimination ability, the scenting method is not immediately considered as food, and when feeding the tasty substance by applying or coating it to the grooves on the outside of the structure, the tasty substance is only licked with the tongue and chewed. It is rare, and in the case of a palatable substance being embedded in a structure, a pet that is experiencing this for the first time will attempt to bite into the chewing substance in order to eat it, but soon realizes that the method is not correct and gives up the attempt at mastication.

As a result, there is a problem with these elastomer structures that pets do not consider them as food but rather perceive them as a kind of play equipment, making it difficult to expect active chewing activities.

In other words, plaque is generated and increased every day due to the food we eat every day, and although its removal must be done every day, the elastomer structure contributes to occasional chewing activities similar to the play activities of pets or falls short of expectations. .

In addition, even if a pet is tempted by the spices coated or included in the structure and plays with or chews the structure, saliva and foreign substances easily get on the structure during this process, becoming a hotbed for the growth of harmful bacteria. There is a risk of worsening the disease of your pet's teeth and gums. To solve this problem, sterilization, washing, and drying must be repeated several times a day immediately after use, but the problem is that these are difficult to do at home.

In addition, the above (Patent Document 1) adopts a slightly hard elastomer structure for stretching action, so a slight flushing effect on teeth and gums can be expected, but it is difficult to remove plaque already firmly attached to the teeth. There are significant difficulties. Therefore, due to these various problems (Patent Document 1), it does not meet the function and expectations as a gum or toy for preventing dental disease at all.

Meanwhile, another example of a chewing gum or toy for preventing dental disease by inducing chewing activity in companion animals is (Patent Document 2). The above (Patent Document 2) includes a consumable body so that a companion animal can chew or eat it, and at least one protrusion is formed on this consumable body.

The consumable body is made of a chewable or edible ingredient, such as so-called modified wheat gluten, or a mixture containing it, and is claimed to prevent dental disease by inducing chewing activity in companion animals.

However, in the above (Patent Document 2), only the effect of rubbing the teeth against the surface occurs during the chewing activity of the companion animal chewing the consumable body, so a slight flushing effect on a very small part of the teeth (mainly the tip) is produced. Although this can be expected, there is a problem in that it does not remove very hard plaque near the gums.

In other words, in order to remove the plaque, the consumable body must not only have a certain mechanical hardness but also be involved deep into the teeth, that is, near the gums, to achieve the goal (Patent Document 2). However, (Patent Document 2) is used in entertainment activities such as chewing or biting by pets. There is a problem in that it is made of a tough and flexible material that can be chewed for a long time, or it is broken into small digestible pieces to fit the digestive system, so its effectiveness is halved.

According to (Patent Document 2), the consumable body is made to have an appropriate hardness that is not 'gushy' or 'sticky', so as to provide a long-lasting chewing effect, mechanical cleaning of the distal end of the teeth, and some flushing effects. Although prevention through plaque control agents may be possible, there is a problem in that they are not effective in removing very hard plaque that is already attached to the top of the teeth, that is, near the gums.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. Embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the following embodiments. This example is provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings are exaggerated to emphasize clearer explanation.

The configuration of the invention to clarify the solution to the problem to be solved by the present invention will be described in detail with reference to the accompanying drawings based on preferred embodiments of the present invention, and the reference numbers to the components in the drawings will be the same. Components are given the same reference numbers even if they are in different drawings, and it is stated in advance that components of other drawings can be cited when necessary when explaining the relevant drawings.

Figure 1 shows the output of a 3D printing composition according to a comparative example and an embodiment of the present invention using a 3D printer, and Figures 2 to 6 are graphs showing the characteristic results of the output of Figure 1.

One embodiment of the present invention may function as a 3D printing composition used to manufacture dental gum that can be consumed by companion animals, especially pet dogs.

The 3D printing composition according to an embodiment of the present invention may include 25 to 35 parts by weight of starch, 10 to 20 parts by weight of a plasticizer, 7 to 21 parts by weight of nutritional substances, and 30 to 40 parts by weight of distilled water.

The starch may be one or more types selected from the group consisting of sweet potato starch, corn starch, rice starch, tapioca starch, and potato starch.

Starch gels at a relatively high temperature in the composition, providing structural stability to dental gum manufactured through 3D printing and determining overall hardness.

In a specific example, corn starch may be used as starch in one embodiment of the present invention. Here, corn starch has a higher viscosity than other starches, so it has a high gel-forming ability and has the effect of giving body in a small amount.

Plasticizers can be used to increase the moisturizing power of the composition and to give the manufactured output an appropriate texture that does not break easily.

Plasticizers include triethyl citrate, sorbitol, triacetin, diethyl phthalate, dibutyl phthalate, polysorbate 80, sorbitan monooleate, propylene glycol, propylene glycol monocaprylate, oleic acid, olive oil, carnauba wax, polyethylene. It may be one or more selected from the group consisting of glycol 400, glycerin, diacetyl monoglyceride, glyceryl monooleate, mineral oil, and dimethylpolysiloxane.

In a specific example, the plasticizer may be composed of glycerin, and is preferably composed of vegetable oil.

Here, 10 to 20 parts by weight of a plasticizer may be included based on 100 parts by weight of the composition for 3D printing.

If the plasticizer is less than 10 parts by weight, it is difficult to maintain the shape of the print produced by a 3D printer. As the plasticizer ratio increases, the hardness of the print increases and the shape is maintained well, but if the plasticizer is more than 20 parts by weight, Stuttering occurs in the middle of output, which actually reduces printability.

Nutrients are added to supplement the nutrition of companion animals, and if the amount exceeds 7 to 21 parts by weight, there may be problems with printability and maintaining the shape of the output.

Meanwhile, the nutritional substance may include 2 to 8 parts by weight of a binder, 2 to 6 parts by weight of carbohydrates, and 3 to 7 parts by weight of protein and 4 to 8 parts by weight of liquid sugar.

A binder may play a role in maintaining the shape of a product. For example, it may refer to a material with a fibrous structure that exists in the space between particles and can form voids.

Binding agents include agar, carrageenan, gellan gum, fuselan, gelatin, curdlan, psyllium seed gum, locust bean gum, xanthan gum, guar gum, pectin, alginic acid, alginate, mannan, and tamarind gum. It may include a mixture of two or more things.

Carbohydrates include one or more selected from the group consisting of maltodextrin, glucose, galactose, trehalose, fructooligosaccharide, sucrose, maltose, isomaltulose, beta-glucan, and triose, and the use of maltodextrin is preferred. desirable.

Here, maltodextrin has various sugar reduction rates, so there is a wide range of options depending on the effect, its safety has been verified, and it is easy to purchase in the market, so it has the advantage of being easy to commercialize.

Proteins include soy protein, wheat gluten, corn zein, corn gluten, sunflower protein, pea protein, peanut protein, rapeseed protein, nut protein, milk protein, collagen, gelatin, keratin, egg albumin, mycoprotein, and combinations thereof. It may be composed of, and is preferably composed of soy protein.

Soy protein is a protein harvested from soybeans that has been processed to make it suitable for human consumption. It is widely used as a substitute for meat or as a source of nutrition, and has physical properties such as solubility, emulsibility, foamability, coagulation, gel forming ability, texturization, and cohesion. Chewing can be improved by adding .

Liquid sugar may include starch syrup, oligosaccharides, honey, and allulose.

Distilled water can be water that has passed through a column of volcanic clusters. In other words, as distilled water is filtered through volcanic clusters, it can be produced using the porosity, purification ability, far-infrared emissivity, and negative ion generation function of the volcanic clusters. Additionally, distilled water that has passed through the column of volcanic clusters can be used after being contained with the volcanic clusters for a certain period of time.

A scoria is a red volcanic soil that is a mixture of porous volcanic rock, volcanic sand, and other volcanic ash, among other materials ejected during a volcanic eruption. In one embodiment, the cluster includes Jeju scoria produced in the Jeju Island region. The main components of Jeju volcanic clusters are silicon oxide (SiO2), aluminum oxide (Al2O3), and iron oxide (FeO). Their content reaches 75% by weight, and it has a stable chemical structure with almost no organic impurities. In addition, Jeju pine contains about 3 to 7 wt% of titanium dioxide in its natural state, which is not found in red clay, jade, elvanite, germanium stone, etc., so it can act as a photocatalyst on its own. In addition, Jeju volcanic clusters are known to have an excellent ability to absorb heavy metals and emit more than 92% of far-infrared rays.

In this way, the distilled water used in the dough of the composition is distilled water that is filtered by the volcanic clusters using the volcanic clusters as a filter and then soaked with the volcanic clusters for a certain period of time, which can make the dough softer and can be used to make the dough more soft. The effect of improving antibacterial activity can occur, making dental gum easier to store.

In addition, synthetic preservatives are used to facilitate the storage of dental gum, which has the effect of reducing or eliminating the use of such synthetic preservatives. By reducing the use of synthetic preservatives, the flavor of dental gum can be preserved and the texture can be maintained or improved.

In addition, the composition further includes a food preservative, and the food preservative may be a Camazum extract.

Capsicum ginseng extract has been found to have excellent growth inhibitory activity and anti-yeast activity stability against food spoilage yeast (Journal of the Korean Society of Food and Nutrition). In addition, black pepper has antipyretic, diuretic, detoxifying, and anti-inflammatory effects and is effective in promoting blood circulation. In particular, it is used as a medicine for colds, chronic bronchitis, nephritis, high blood pressure, jaundice, erysipelas, boils, and tumors. By further including this extract of Camajung, the storage stability of the dental gum can be further improved, and a functional dental gum that can prevent diseases such as colds in companion animals can be manufactured.

And, the amount of the Camazhong extract may be 0.001 to 20 parts by weight based on distilled water. At this time, the Camajung extract may be mixed with distilled water. In addition, if the amount of the soybean extract is included in less than 0.001 parts by weight, the effect of inhibiting the growth of spoilage bacteria is low and the food preservation effect is minimal. If it exceeds 1 part by weight, the increase in the effect of inhibiting the growth of spoilage bacteria may not be significant. .

Meanwhile, the 3D printing composition according to an embodiment of the present invention contains, in addition to the above-described composition, palatability enhancers such as beef and pork to provide palatability, plaque removers such as phosphate to prevent plaque formation, and nutrients such as vitamin B group. Additional information may be included.

Hereinafter, an experimental example examining the characteristic evaluation of a print produced using the above-described 3D printing composition will be described.

[Experimental Example 1]

As shown in [Table 1] below, a composition with a set mixing ratio was prepared and then sufficiently hydrated in a 4°C refrigerator for 24 hours before being used in the experiment. Afterwards, the composition was manufactured into a cylindrical output using a 3D printer, and the storage modulus (G') and loss modulus (G'') of the manufactured output were measured through a frequency sweep test and extruded during the printing process. When the flowability, that is, rheological behavior, was evaluated.

Composition ingredients
(weight%) Comparative Example 1 Example 1 Example 2 Comparative Example 2 corn starch 30 30 30 30 Agar powder 5 5 5 5 maltodextrin 4 4 4 4 Soy protein isolate 5 5 5 5 glycerin 0 10 20 30 corn syrup 6 6 6 6 Distilled water 50 40 30 20 Sum 100 100 100 100

Here, the frequency change test was measured using a controlled stress rheometer (Paar Physica MCR 302, Anton Paar, Graz, Austria). A sandblasted parallel plate (PP25/S) with a diameter of 25 mm was used and set to a gap of 1.3 mm. A dynamic strain sweep test was first performed to obtain the linear viscoelastic response range (Linear viscoelastic region), and then a frequency sweep test was performed at 0.1% strain. All loaded samples were left for 15 minutes before testing began to allow the collapsed internal tissue to recover.

2-3 graphs are shown showing the variation of the measured dynamic viscoelastic properties (G' and G'') within the frequency range tested. Depending on the amount of added glycerin, the values of G' and G'' of the composition increased correspondingly. This confirms that the rheological properties of the dental gum composition depend on the amount of glycerin incorporated.

In addition, in all compositions, the storage modulus G' value was higher than the loss modulus G'', showing solid-like behavior appropriate for maintaining the shape immediately after printing.

Meanwhile, referring to Figure 4, as the angular frequency increases, the complex viscosity decreases in all compositions, so it can be said that they exhibit pseudoplastic, shear-thinning fluid, which results in a relatively low viscosity during printing. Afterwards, it can be confirmed that it is suitable for maintaining its shape.

Figures 5 and 6 show the results of printing a composition with glycerin added using a 3D food printer.

Printed in a cylindrical shape of 30 mm (diameter) It was expressed as post-shape stability (%) (height after 1 hour/height immediately after printing x 100).

In the case of printability, Comparative Example 2, in which 30% of glycerin was added, was significantly inferior, and it can be seen that it was difficult to maintain the shape if glycerin was not added. In other words, as glycerin is added, the hardness increases and the shape is maintained well, but if it exceeds 20%, a break occurs in the middle of the output, which actually reduces the printability. This can be confirmed to be consistent with the rheological behavior trends in Figures 2 to 4.

Hereinafter, dental gum for companion animals manufactured using a 3D printing composition according to an embodiment of the present invention will be described.

Dental gum 100 for companion animals according to an embodiment of the present invention can be manufactured by 3D printing the above-described 3D printing composition.

Specifically, the 3D printed output was sufficiently gelatinized by steaming it in a steamer for 40 minutes, then cooling it for about 10 minutes and drying it with hot air at 75°C for 4 to 6 hours.

Here, the drying time can be adjusted as needed, and the moisture content is set to about 15-20%. This is generally higher than dental gum commercially available through extrusion molding (approximately 5-15%).

In general, high-moisture products are easy to digest, and because their hardness is relatively low, they have the advantage of minimizing gum damage.

Figure 7 is an exemplary diagram schematically showing dental gum for companion animals manufactured using a 3D printing composition according to an embodiment of the present invention, and Figure 8 is a diagram showing dental gum for companion animals manufactured by varying the density of the 3D printing composition according to an embodiment of the present invention. This is an example schematically showing dental gum for pets.

Referring to Figures 7 and 8, the dental gum 100 for pets according to an embodiment of the present invention may be constructed by stacking a plurality of layers 101 and 102. Here, each layer (101, 102) may be formed of filament printed by 3D printing.

Additionally, the dental gum 100 may include an inner region 110 and an outer region 120 surrounding the inner region.

The inner region 110 is formed by a separate pattern 111 for each layer 101 and 102 and a through hole 112 into which the pet's tooth is inserted.

It is advantageous in 3D printing that the pattern 111 is formed in a grid pattern as shown in FIGS. 7 and 8, but of course it can be formed in various shapes depending on the design.

Here, each layer (101, 102) has a different formed pattern (111), and accordingly, the through hole (112) formed in each layer (101, 102) is not formed straight in the height direction, but is curved. Can be connected through channels. Specifically, the through hole 112 of a specific layer 101 may communicate with one or at least two through holes 112 among the plurality of through holes 112 of the layer 102 disposed at the top or bottom.

That is, along the height direction, the through hole 112 is branched from each layer 101 and 102, or one through hole 112 in two layers 101 is located directly at the top or bottom of another layer 102. It may be in communication with a plurality of through holes 112.

On the other hand, it is desirable to have a diameter narrow enough to provide sufficient friction when the pet's teeth enter the through hole 112.

Here, the teeth of companion animals differ depending on the animal species, and even one species of animal has various teeth with different thicknesses, such as molars and canines, corresponding to various teeth rather than the through hole 112 having a constant diameter, and the height The area and probability of friction between various teeth and the inner surface of the through hole 112, which is formed in a serpentine direction, may be increased. In addition, the through hole 112 is curved along the height direction, so that the steps forming the through hole 112 at the interface of each layer 101 and 102 can perform a scraper function.

Meanwhile, the dental gum 100 preferably has a surface hardness of about 100N to 350N so that plaque can be removed through physical friction with the animal's teeth. Here, if the surface hardness is less than 100N, the physical friction is low and is not effective in removing plaque, and if the surface hardness is more than 350N, it is too hard and may cause a burden on the pet's teeth and gums.

Meanwhile, the volume occupied by the plurality of through holes 112 is preferably 40% to 60% of the total volume of the dental gum 100.

Conversely, it is preferable that the internal filling degree (density) of the dental gum 100 is 40% to 60%.

Here, if the degree of internal filling (density) is less than 40%, it may be difficult to maintain the shape of the product and the plaque removal effect may be reduced due to low friction. In addition, when the degree of internal filling (density) is more than 60%, there is a problem that the manufactured dental gum 100 tends to clump together and crumble more easily.

[Experimental Example 2]

After manufacturing dental gum using the compositions of Examples 1 and 2 described above, physical properties were measured and plaque removal tests were conducted.

As shown in Figure 9 below, it was printed in a rectangular shape of 105 mm x 18 mm x 13 mm with a 1.5 mm nozzle and a speed of 40 mm/s. In addition, in order to compare the plaque removal effect by internal structure of dental gum, the infill pattern was set to a rectilinear pattern and the internal filling density (infill level) was 40, 60, and 80% using the Slic3r program for Examples 1 and 2, respectively. It was printed as .

As described above, by controlling the shape of the through hole of dental gum, it can be fully applied depending on the species or age of the companion animal.

Meanwhile, each output was sufficiently gelatinized by steaming in a steamer for about 40 minutes, then cooled for about 10 minutes, and dried with hot air at 75°C for 4 to 6 hours.

The dried dental gum was subjected to a puncture test and a three-point bending test using a physical property measuring device (TAXT plus 50, Stable Micro Systems, UK).

It was conducted with a 20 mm cylinder probe (P/20), and the three-point bending test was conducted with a blade probe (HDP/BS) with the floors set at 40 mm intervals. In both tests, the test speed was set at 1.00 mm/s and the pre/post speed was set at 5.00 mm/s.

Referring to Figures 10 and 11, in the case of the internal pressure test, the hardness increases as the degree of internal filling increases, and the same trend is shown in the three-point bending test. In general, small dogs (body weight of 11.4 kg or less) show a high preference for 250 N to 400 N, and it can be confirmed that both Examples 1 and 2 fall within that range.

On the other hand, referring to Figure 12, in the case of brittleness, the degree of internal filling increases, and at 80%, it is relatively lower than at 40 or 60%. This means that as the internal filling increases, the texture becomes similar to that of extruded gum, and it clumps and crumbles more easily. It can be seen that there is a tendency to lose.

[Experimental Example 3]

As shown in Figure 13, in order to see the mechanical effect of plaque removal, the upper canines (#104) and upper premolars (#208) were removed from the dog tooth model, and then the teeth were buried using paraffin as artificial plaque, and the degree to which paraffin was removed was measured. .

A physical property measuring device (Lamy TA-TX 700, Germany) was used to apply force to the teeth on the dental gum with the same pressure, and the teeth were attached to the compression test probe and applied force by lowering them at a speed of 5 mm/s.

The plaque removal effect test results can be seen in Figures 14 and 15. First of all, you can see that the teeth go into the holes made in the internal grid pattern of the overall dental gum, scraping off the paraffin coated on the surface of the teeth, creating mechanical friction and acting as an abrasive.

In addition, as the degree of internal filling of dental gum increases, the lattice becomes denser and the removal effect appears to be higher. However, when it exceeds 80%, it becomes excessively dense and crumbles, reducing the removal effect. It can be confirmed that this corresponds to the tendency of brittleness in the three-point bending test.

Meanwhile, comparing Examples 1 and 2, although the removal effect is higher in Example 2 than in Example 1, the difference is to a degree that can be overcome by the internal filling concentration. Additionally, the overall removal effect was higher for canines than for premolars, which appears to be due to the shape characteristics of premolars due to the groove in the middle.

The above detailed description is illustrative of the present invention. Additionally, the foregoing is intended to illustrate preferred embodiments of the present invention, and the present invention can be used in various other combinations, modifications, and environments. That is, changes or modifications can be made within the scope of the inventive concept disclosed in this specification, a scope equivalent to the written disclosure, and/or within the scope of technology or knowledge in the art.
