[0048] The present application will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments do not limit the present application, and structural, methodological, or functional changes made by those skilled in the art based on these embodiments are included in the scope of the present application.

[0049] In conjunction with Figure 1 and Figure 2 , a dental instrument 100 and an indicator 10 according to an embodiment of the present application are shown, the indicator 10 being used for the dental instrument 100.

[0050] Here, the dental instrument 100 is used in the oral cavity, and the present embodiment is described by taking a shell-shaped orthodontic appliance as an example. In other embodiments, the dental instrument 100 can also be other dental instruments that need to be worn in the oral cavity for a certain period of time, such as an oral facial muscle trainer, etc.

[0051] The dental appliance 100 comprises a dental appliance body 101 and the indicator 10 arranged on the dental appliance body 101, the dental appliance body 101 forms a cavity S for accommodating teeth, and the dental appliance body 101 is generally made of transparent material.

[0052] The cavity S of the dental appliance 100 for accommodating teeth has a geometry for repositioning the teeth of the patient from a first layout to a second layout, for example, the geometry of the cavity S of the dental appliance 100 can be determined based on the second layout of the teeth of the patient, or the geometry of the cavity S of the dental appliance 100 can substantially match the second layout of the teeth of the patient.

[0053] In the present embodiment, the indicator 10 can be a product independently produced and subsequently used in the dental appliance 100.

[0054] The indicator 10 is arranged on one side of the dental appliance body 101 close to the lingual side, and / or the indicator 10 is arranged on one side of the dental appliance body 101 close to the labial side.

[0055] Here, the number and position of the indicator 10 are not limited and can be determined according to actual conditions, as long as the indicator 10 can contact the oral environment.

[0056] In combination Figure 2 and Figure 3 are schematic views of the indicator 10 of the first embodiment of the present application and the dental appliance 100 with the indicator 10.

[0057] The indicator 10 comprises an adsorption layer 11 and a display layer 12, when the adsorption layer 11 adsorbs the acting substance in the oral cavity and reaches a saturation state, the acting substance penetrates to the display layer 12 through the adsorption layer 11, and the display layer 12 exhibits a pattern under the action of the acting substance.

[0058] Here, the acting substance in the oral cavity is a mutagenic factor that can control the display layer 12 to exhibit a pattern, and the acting substance is, for example, saliva in the oral cavity.

[0059] The "display layer 12 exhibits a pattern" means that the state of the display layer 12 changes, for example, the volume, shape, color, pattern, etc. of the display layer 12 changes, and these changes can be directly observed.

[0060] In the present embodiment, when the dental appliance 100 is not worn sufficiently, the acting substance adsorbed by the adsorption layer 11 does not reach a saturation state, and the acting substance cannot penetrate to the display layer 12, that is, the display layer 12 does not exhibit a pattern, and the display layer 12 still maintains the initial unchanged state.

[0061] When the dental appliance 100 is worn for a long time, the adsorption layer 11 reaches a saturation state, and the effecting substance penetrates into the display layer 12 through the adsorption layer 11, and the display layer 12 displays a pattern, so that the wearing time of the dental appliance 100 can be determined according to the pattern displayed by the display layer 12.

[0062] The adsorption layer 11 of the embodiment can continuously adsorb the effecting substance, for example, continuously adsorb saliva, and the effecting substance interacts with the display layer 12 only when the adsorption layer 11 reaches the saturation state, that is, the display layer 12 does not change at all when the adsorption layer 11 does not reach the saturation state, and the display layer 12 changes only when the adsorption layer 11 reaches the saturation state, which can greatly improve the accuracy of the indicator 10.

[0063] Here, compared with the scheme in which the indicator 10 changes all the time during the whole wearing process, the indicator 10 of the embodiment changes only when the adsorption layer 11 reaches the saturation state, and the time when the adsorption layer 11 reaches the saturation state is controllable, for example, by controlling the material and thickness of the adsorption layer 11, on the one hand, the wearing time can be accurately indicated by controlling the time when the adsorption layer 11 reaches the saturation state, and on the other hand, the situation of incorrect judgment due to the fact that the indicator 10 is always in the changing process can be avoided.

[0064] In the embodiment, the adsorption layer 11 may, for example, be composed of a material with a large water absorption rate, such as polyurethane, polyvinyl alcohol, silica gel desiccant, etc.

[0065] The display layer 12 may, for example, be composed of a material that changes in state under the influence of the effecting substance in the oral cavity, for example, the material included in the display layer 12 changes color under the influence of the effecting substance, which can be from transparent to a color, from a color to transparent, from one color to another color, etc., and the color change of the display layer 12 can be directly observed.

[0066] Alternatively, the material included in the display layer 12 presents a hidden pattern under the influence of the effecting substance, for example, a specific color, a smiling pattern, corresponding text, a product trademark, etc.

[0067] In the embodiment, the indicator 10 further includes an encapsulation layer 13 encapsulating the adsorption layer 11 and the display layer 12, and the encapsulation layer 13 has a through hole 131 communicating the adsorption layer 11 and the oral cavity, so that the effecting substance in the oral cavity contacts the adsorption layer 11 through the through hole 131.

[0068] Here, "encapsulating" means that the encapsulation layer 13 surrounds part or all of the structure of the indicator 10, so as to control the path of the effecting substance in the oral cavity acting on the indicator 10, and avoid the direct contact of the effecting substance with the display layer 12 to cause the change of the display layer 12.

[0069] In addition, the encapsulation layer 13 is made of water-proof material, and the through hole 131 is small in size, so that the water used for flushing is not easy to penetrate the encapsulation layer 13 to enter the indicator 10 during the flushing process of the dental instrument 100, which can avoid the influence of factors such as flushing the dental instrument 100 on the accuracy of the indication of the indicator 10.

[0070] In the embodiment, the encapsulation layer 13 can be a porous polymer film, for example, a porous polymer film made of polymers such as polyurethane, silica gel, polyacrylic acid, etc. The amount of the acting substance penetrating can be adjusted by controlling the number and size of the through hole 131 of the encapsulation layer 13 (i.e. controlling the porosity of the encapsulation layer 13), and the time for the adsorption layer 11 to reach the saturation state can be further controlled.

[0071] In the embodiment, the encapsulation layer 13 encapsulates the upper surface, the periphery and the lower surface of the adsorption layer 11 and the display layer 12, that is, the encapsulation layer 13 wraps the entire outer surface of the adsorption layer 11 and the display layer 12, and only the through hole 131 is formed in the area corresponding to the adsorption layer 11. In this way, the indicator 10 with the encapsulation layer 13 can be used as an independent product and is not easily affected by the external environment. The indicator 10 as an independent product can be flexibly used in various dental instruments.

[0072] In other embodiments, the side surface of the display layer 12 away from the adsorption layer 11 can also not be encapsulated by the encapsulation layer 13, for example, a removable release paper is arranged on the side surface of the display layer 12 away from the adsorption layer 11. When the indicator 10 is installed at the dental instrument body 101, the release paper is removed and the indicator 10 is fixed to the dental instrument body 101, or the indicator 10 is directly formed on the dental instrument body 101.

[0073] Next, various specific examples of the dental instrument 100 with the indicator 10 in the first embodiment are introduced.

[0074] In the first specific example, in combination with Figure 2 and Figure 3 The display layer 12 includes a pattern layer 122 and a reaction layer 121 shielding the pattern layer 122, and the acting substance controls the reaction layer 121 to become transparent to expose the pattern layer 122.

[0075] Here, the reaction layer 121 shielding the pattern layer 122 means that from the observation end, the reaction layer 121 is located outside the pattern layer 122. When the reaction layer 121 does not change, the reaction layer 121 shields the pattern layer 122 so that the pattern of the pattern layer 122 cannot be observed. When the reaction layer 121 changes and becomes transparent, the pattern displayed by the pattern layer 122 can be observed through the reaction layer 121.

[0076] The reaction layer 121 is formed of a material that becomes transparent when exposed to water, for example, a material that becomes transparent when the refractive index and / or the reflected light wavelength and / or the crystalline state and the like change after absorbing water.

[0077] The display layer 12 is a structure with a display function, for example, the display layer 12 has a specific color or a specific pattern.

[0078] When the adsorption layer 11 reaches the saturated state, the reaction layer 121 becomes transparent due to the penetration of the agent, and the pattern layer 122 is exposed, and when the pattern displayed by the pattern layer 122 is observed, it indicates that the indicator 10 has been worn sufficiently.

[0079] The reaction layer 121 of the present example becomes transparent to expose the pattern layer 122 only when the adsorption layer 11 reaches the saturated state, which can greatly improve the accuracy of the indicator 10.

[0080] In the present example, the reaction layer 121 and the pattern layer 122 are located on one side of the outer surface 1011 of the dental instrument body 101, and the adsorption layer 11 is connected to the reaction layer 121, and the adsorption layer 11 is located on the side of the reaction layer 121 away from the teeth.

[0081] Here, "one side of the outer surface 1011 of the dental instrument body 101" refers to the side away from the cavity S.

[0082] From the direction Y from close to the cavity S to away from the cavity S, the pattern layer 122, the reaction layer 121, and the adsorption layer 11 of the present example are sequentially stacked and connected, and the encapsulation layer 13 simultaneously encapsulates the pattern layer 122, the reaction layer 121, and the adsorption layer 11.

[0083] The pattern layer 122, the reaction layer 121, and the adsorption layer 11, and the encapsulation layer 13 can be formed by spraying, stenciling, screen printing, injection molding, extrusion molding, hot press molding, and the like.

[0084] In the present example, the adsorption layer 11 is a transparent layer, and the adsorption layer 11 remains a transparent layer after absorbing the agent.

[0085] The adsorption layer 11 is located between the reaction layer 121 and the oral cavity to isolate the reaction layer 121 and the oral cavity, and the agent enters the adsorption layer 11 and the reaction layer 121 in sequence along the stacking direction of the adsorption layer 11, the reaction layer 121, and the pattern layer 122, and when the reaction layer 12 changes and becomes transparent, since the adsorption layer 11 and the reaction layer 121 are both transparent, the pattern displayed by the pattern layer 122 can be observed from one side of the outer surface 1011 of the dental instrument body 101.

[0086] In the present example, the encapsulation layer 13 is located between the pattern layer 122 and the dental instrument body 101, and the side surface of the encapsulation layer 13 away from the pattern layer 122 is fixed to the dental instrument body 101. Of course, in other examples, the pattern layer 122 can be directly connected to the dental instrument body 101, i.e., the encapsulation layer 13 below the pattern layer 122 is cancelled. Figure 4 , the pattern layer 122 can also be directly connected to the dental instrument body 101, i.e., the encapsulation layer 13 below the pattern layer 122 is cancelled.

[0087] It should be noted that in other examples, at least one of the adsorption layer 11, the reaction layer 121 and the pattern layer 122 is a multi-layer structure.

[0088] That is, the adsorption layer 11 can be a single-layer structure or a multi-layer structure, and the same applies to the reaction layer 121 and the pattern layer 122.

[0089] In addition, when being a multi-layer structure, the multi-layer structure can be a multi-layer structure with the same material and function, or a multi-layer structure with different materials or functions.

[0090] Specifically, in combination with Figure 5 The adsorption layer 11 includes three adsorption layers 112, 113 and 114 stacked in sequence, and the thickness, size, material and porosity of the three adsorption layers 112, 113 and 114 can be arbitrarily selected according to actual needs. The adsorption capacity of the three adsorption layers 112, 113 and 114 can be the same or different, for example, the adsorption capacity of the three adsorption layers 112, 113 and 114 is different and corresponds to different adsorption saturation times, so that different adsorption layers can be selected according to the actual wearing time indicated as needed.

[0091] It can be understood that the number of layers of the adsorption layer 11 can be determined according to actual conditions, and a bonding layer or other structural layer can be included between adjacent adsorption layers.

[0092] The reaction layer 121 is a single-layer structure, but is not limited thereto.

[0093] The pattern layer 122 includes two pattern layers 1221 and 1222 stacked in sequence, and the pattern, color, size and material of the two pattern layers 1221 and 1222 can be arbitrarily selected according to actual conditions. When the pattern layer 122 is displayed, only one of the two pattern layers can be displayed, or both of the two pattern layers 1221 and 1222 can be displayed simultaneously, or the two pattern layers 1221 and 1222 can be displayed in sequence, for example, the size of the upper pattern layer 1221 is smaller than the size of the lower pattern layer 1222, and both of the two pattern layers 1221 and 1222 are displayed simultaneously, the lower pattern layer 1222 is displayed on the periphery of the upper pattern layer 1221, or the upper pattern layer 1221 has a hollow area exposing the lower pattern layer 1222, etc.

[0094] In combination withFigure 6 As a second specific example, a schematic diagram of a dental instrument 100a with an indicator 10a is shown, for ease of illustration, structures same or similar to the first specific example are numbered same or similarly, the same below.

[0095] In the second specific example, the indicator 10a comprises a pattern layer 122a, a reaction layer 121a and an adsorption layer 11a in sequence.

[0096] The adsorption layer 11a is a transparent layer, when the reaction layer 121a changes and becomes transparent, the pattern exhibited by the pattern layer 122a can be observed from one side of the outer surface 1011a of the dental instrument body 101a.

[0097] The encapsulation layer 13a encapsulates the adsorption layer 11a, the reaction layer 121a and the pattern layer 122a, and the encapsulation layer 13a has a through hole 131a communicating the adsorption layer 11a and the oral cavity.

[0098] The adsorption layer 11a extends into the through hole 131a.

[0099] Specifically, the adsorption layer 11a has a protrusion 111a extending towards the through hole 131a, the protrusion 111a fills the through hole 131a, and the top end of the protrusion 111a is flush with the top surface of the encapsulation layer 13a, so that the effect of the oral cavity can be effectively avoided. The effect of the oral cavity directly enters the inside of the indicator 10a from the gap between the adsorption layer 11a and the encapsulation layer 13a to contact the reaction layer 121a, in other words, the present example can effectively control the effect of the oral cavity to penetrate into the reaction layer 121a through the adsorption layer 11a first.

[0100] Other descriptions of the dental instrument 100a of the second specific example can refer to the descriptions of the foregoing or subsequent specific examples, which will not be described here.

[0101] In combination Figure 7 As a third specific example, a schematic diagram of a dental instrument 100b is shown.

[0102] In the third specific example, the indicator 10b comprises an adsorption layer 11b and a reaction layer 121b located at the periphery of the adsorption layer 11b.

[0103] Specifically, the reaction layer 121b surrounds the periphery of the adsorption layer 11b, of course, in other examples, the reaction layer 121b can be provided only on one side of the adsorption layer 11b.

[0104] The pattern layer 122b is located between the outer surface 1011b of the dental instrument body 101b and the reaction layer 121b, and the reaction layer 121b blocks the pattern layer 122b.

[0105] The encapsulation layer 13b encapsulates the adsorption layer 11b, the reaction layer 121b and the pattern layer 122b, and is located between the reaction layer 121b and the oral cavity to isolate the reaction layer 121b and the oral cavity.

[0106] Here, the adsorption layer 11b and the reaction layer 121b are arranged in connection along the tooth arrangement direction X (i.e., the direction parallel to the outer surface 1011b of the dental instrument body 101b), and when the adsorption layer 11b reaches the saturation state, the agent penetrates into the reaction layer 121b along the tooth arrangement direction X, the reaction layer 121b changes and becomes transparent, and the pattern displayed by the pattern layer 122b can be observed from one side of the reaction layer 121b.

[0107] At this time, the adsorption layer 11b can be a transparent layer or a non-transparent layer, and when it is a non-transparent layer, the pattern layer 122b can also extend below the adsorption layer 11b.

[0108] The dental instrument 100b of the third specific example can be further described with reference to the descriptions of the foregoing or subsequent specific examples, which will not be repeated here.

[0109] In combination Figure 8 A schematic diagram of a dental instrument 100c of a fourth specific example is shown.

[0110] In the fourth specific example, the indicator 10c includes an adsorption layer 11c and a reaction layer 121c located at the periphery of the adsorption layer 11c.

[0111] Specifically, the reaction layer 121c surrounds the periphery of the adsorption layer 11c and is located on opposite sides of the pattern layer 122c, i.e., the pattern layer 122c is sandwiched between the reaction layer 121c.

[0112] The encapsulation layer 13c encapsulates the adsorption layer 11c, the reaction layer 121c and the pattern layer 122c, and is located between the reaction layer 121c and the oral cavity to isolate the reaction layer 121c and the oral cavity.

[0113] Here, the adsorption layer 11c and the reaction layer 121c are arranged in connection along the tooth arrangement direction X, and when the adsorption layer 11c reaches the saturation state, the agent penetrates into the reaction layers 121c located on the upper and lower sides of the pattern layer 122c along the tooth arrangement direction X, the reaction layers 121c change and become transparent, and the pattern displayed by the pattern layer 122c can be observed from one side of the outer surface 1011c and one side of the inner surface 1012c of the dental instrument body 101c.

[0114] In this example, when the reaction layer 121c does not change, the reaction layer 121c blocks the opposite two surfaces of the pattern layer 122c, so that the pattern layer 122c is completely invisible, and observation errors can be avoided.

[0115] Other descriptions of the dental instrument 100c of the fourth specific example can refer to the descriptions of the foregoing or subsequent specific examples, which will not be repeated here.

[0116] In combination Figure 9 A schematic view of a dental instrument 100d of a fifth specific example is shown.

[0117] In the fifth specific example, the indicator 10d comprises a superimposed adsorption layer 11d and a display layer 12d.

[0118] The display layer 12d is a single-layer structure, and the adsorption layer 11d is connected to the display layer 12d. The adsorption layer 11d is located on the side of the display layer 12d away from the tooth, and the display layer 12d is close to the body 101d of the dental instrument.

[0119] The encapsulation layer 13d simultaneously encapsulates the display layer 12d and the adsorption layer 11d, and the encapsulation layer 13d is located between the adsorption layer 11d and the oral cavity to isolate the adsorption layer 11d and the oral cavity.

[0120] In the present example, the adsorption layer 11d is a transparent layer, and the adsorption layer 11d remains a transparent layer after adsorbing the action object.

[0121] The display layer 12d is a structure that changes under the action of the action object.

[0122] For example, the display layer 12d changes color under the action of the action object. Specifically, when the display layer 12d does not contact the action object, the display layer 12d displays a first color, and when the display layer 12d contacts the action object, the display layer 12d changes to a second color.

[0123] Alternatively, the display layer 12d fades under the action of the action object. Specifically, when the display layer 12d does not contact the action object, the display layer 12d displays a specific color, and when the display layer 12d contacts the action object, the display layer 12d fades. At this time, the display layer 12d may, for example, be a starch-iodine inclusion compound, which will only decompose and fade under the action of salivary amylase in saliva. The fading process of the display layer 12d can be avoided from being affected by carbonated beverages or other action objects.

[0124] Alternatively, the display layer 12d displays a pattern under the action of the action object. Specifically, when the display layer 12d does not contact the action object, the pattern at the display layer 12d is not displayed, and when the display layer 12d contacts the action object, the display layer 12d displays the pattern.

[0125] Of course, the changes of the display layer 12d under the action of the action object are not limited to the above descriptions.

[0126] The adsorption layer 11d is located between the display layer 12d and the oral cavity to isolate the display layer 12d and the oral cavity, and the object enters the adsorption layer 11d and the display layer 12d in sequence along the stacking direction of the adsorption layer 11d and the display layer 12d, and when the display layer 12d changes, the pattern displayed by the display layer 12d can be observed from one side of the outer surface 1011d of the dental instrument body 101d due to the transparency of the adsorption layer 11d.

[0127] Compared with the foregoing examples, the display layer 12d of the present example is a single-layer structure, so that the overall structure of the indicator 10d is simpler.

[0128] The dental instrument 100d of the fifth specific example can be further described with reference to the foregoing or the following specific examples, which will not be repeated here.

[0129] In combination Figure 10 The sixth specific example is a schematic diagram of a dental instrument 100e.

[0130] In the sixth specific example, the display layer 12e is a single-layer structure, and the display layer 12e surrounds the periphery of the adsorption layer 11e.

[0131] The encapsulation layer 13e simultaneously encapsulates the display layer 12e and the adsorption layer 11e, and the encapsulation layer 13e is located between the display layer 12e and the oral cavity to isolate the display layer 12e and the oral cavity.

[0132] Here, the adsorption layer 11e and the display layer 12e are connected and arranged along the tooth arrangement direction X, and when the adsorption layer 11e reaches a saturation state, the object penetrates the display layer 12e along the tooth arrangement direction X, and the display layer 12e changes to display a pattern.

[0133] At this time, the adsorption layer 11e can be a transparent layer or a non-transparent layer, and when it is a non-transparent layer, the display layer 12e can also extend below the adsorption layer 11e.

[0134] The dental instrument 100e of the sixth specific example can be further described with reference to the foregoing or the following specific examples, which will not be repeated here.

[0135] In the first embodiment, the dental instrument 100 can also include a plurality of indicators 10 stacked in sequence, and the plurality of indicators 10 can display patterns in sequence to indicate a plurality of wearing times, which can be further described with reference to the following second embodiment.

[0136] In combination Figure 11 and Figure 12 The sixth specific example is a schematic diagram of a dental instrument 100e.

[0137] For the convenience of description, the same or similar structures in the second embodiment as those in the first embodiment are denoted by the same or similar numbers, which will not be repeated here.

[0138] In the second embodiment, the indicator 10 comprises a first indicator 20 and a second indicator 30 stacked.

[0139] The first indicator 20 comprises a first pattern layer 21, and the second indicator 30 comprises a second pattern layer 31. The agent in the oral cavity penetrates the first indicator 20 and the second indicator 30 in sequence, so that the first pattern layer 21 and the second pattern layer 31 display patterns in sequence.

[0140] Here, the agent in the oral cavity gradually penetrates along the stacking direction of the first indicator 20 and the second indicator 30. With the penetration of the agent in the oral cavity, the first pattern layer 21 and the second pattern layer 31 display patterns in sequence, which can indicate multiple time nodes of wearing.

[0141] Specifically, it is assumed that the first pattern layer 21 displays a pattern when worn for 7 days, and the second pattern layer 31 displays a pattern when worn for 14 days. That is, the first pattern layer 21 indicates a 7-day wearing time node, and the second pattern layer 31 indicates a 14-day wearing time node. The wearing time of the dental appliance 100 can be determined by observing the displayed pattern, and the dental appliance 100 can adapt to different needs.

[0142] It can be understood that the present embodiment takes the indicator 10 having the first indicator 20 and the second indicator 30 as an example for illustration. In other embodiments, the dental appliance 100 can also include a third indicator.

[0143] In addition, the specific form of the displayed pattern can refer to the first embodiment, which will not be described here again.

[0144] In the present embodiment, the indicator 10 further comprises an encapsulation layer 40 encapsulating the first indicator 20 and the second indicator 30, and the encapsulation layer 40 has a through hole 41 communicating with the first indicator 20 and the oral cavity.

[0145] Other descriptions of the encapsulation layer 40 of the present embodiment can refer to the first embodiment, which will not be described here again.

[0146] It can be understood that the wearing time indicated by each indicator 10 can be adjusted by the number and size of the through holes 41 of the encapsulation layer 40, as well as the material and thickness of the pattern layer.

[0147] In the present embodiment, the first pattern layer 21 can be directly connected to the second pattern layer 31, or the first pattern layer 21 is indirectly connected to the second pattern layer 31.

[0148] That is, the first indicator 20 can only include the first pattern layer 21, or the first indicator 20 further includes other functional layers. Similarly, the second indicator 30 can only include the second pattern layer 31, or the second indicator 30 further includes other functional layers.

[0149] Next, various specific examples of the dental instrument 100 in the second embodiment are described.

[0150] In a first specific example, in combination with Figure 12 , the first indicator 20 is located on the side of the second indicator 30 away from the teeth.

[0151] The first indicator 20 only includes the first pattern layer 21, and the second indicator 30 only includes the second pattern layer 31, and the first pattern layer 21 is connected to the second pattern layer 31.

[0152] In this example, the first pattern layer 21 and the second pattern layer 31 are both located on one side of the outer surface 1011 of the dental instrument body 101, the second pattern layer 31 is close to the dental instrument body 101, and the first pattern layer 21 is located on the side of the second pattern layer 31 away from the teeth, that is, in the direction Y from close to the cavity S to away from the cavity S, the second pattern layer 31 and the first pattern layer 21 in this example are sequentially stacked and connected.

[0153] The packaging layer 40 simultaneously encapsulates the first pattern layer 21 and the second pattern layer 31, and the packaging layer 40 is located between the first pattern layer 21 and the oral cavity to isolate the second pattern layer 31 and the oral cavity.

[0154] In this example, the first pattern layer 21 shields the second pattern layer 31, and taking an example in which the first pattern layer 21 and the second pattern layer 31 include different starch-iodine inclusions as an illustration, the starch-iodine inclusions gradually fade under the action of salivary amylase in saliva, and in other examples, the pattern layer can be made of other materials.

[0155] The first pattern layer 21 is composed of dextrin-iodine inclusions, and when the first pattern layer 21 does not display a pattern, the first pattern layer 21 displays red.

[0156] The second pattern layer 31 is composed of amylopectin-iodine inclusions, and when the second pattern layer 31 does not display a pattern, the second pattern layer 31 displays purple red.

[0157] When the saliva in the oral cavity does not enter the inside of the packaging layer 40, only the red color displayed by the first pattern layer 31 can be observed on one side of the outer surface 1011 of the dental instrument body 101.

[0158] When the saliva in the oral cavity enters the inside of the packaging layer 40, the saliva first contacts the first pattern layer 21, the red color of the first pattern layer 21 gradually fades and becomes transparent, and until the purple red color displayed by the second pattern layer 32 is observed, at this time, it can be indicated that the dental instrument 100 has been worn to the first time node.

[0159] Then saliva permeates to the second pattern layer 31, the purple-red color of the second pattern layer 31 gradually fades away until it is completely faded away, at which time it can be indicated that the dental instrument 100 has been worn to the second time node.

[0160] In combination Figure 13 The dental instrument 100 can further include a third indicator 50, which only includes a third pattern layer 51 composed of amylose-iodine inclusion complex, and the third pattern layer 51 exhibits a blue color when it does not exhibit a pattern.

[0161] Here, other descriptions of the third indicator 50 can refer to the foregoing descriptions, which will not be repeated here. By providing the third indicator 50, the number of time nodes that the dental instrument 100 can indicate can be further increased.

[0162] In combination Figure 14 And Figure 15 A schematic view of the dental instrument 100a of the second specific example.

[0163] In the second specific example, the first indicator 20a is located on the side of the second indicator 30a away from the teeth.

[0164] The first indicator 20a only includes the first pattern layer 21a, and the second indicator 30a only includes the second pattern layer 31a, which is close to the dental instrument body 101a. The first pattern layer 21a is located on the side of the second pattern layer 31a away from the teeth, and the first pattern layer 21a is connected to the second pattern layer 31a.

[0165] The cross sections of the first pattern layer 21a and the second pattern layer 31a are both circular, the first pattern layer 21a and the second pattern layer 31a are concentric circles, the size of the second pattern layer 31a is greater than the size of the first pattern layer 21a, and at this time, the outer contour of the second pattern layer 31a is located on the outside of the outer contour of the first pattern layer 21a.

[0166] The encapsulation layer 40a simultaneously encapsulates the first pattern layer 21a and the second pattern layer 31a, and the encapsulation layer 40a is located between the first pattern layer 40a and the oral cavity to isolate the second pattern layer 31a and the oral cavity.

[0167] It should be noted that at this time, a step portion 42a is formed at the edge region of the first pattern layer 21a and the second pattern layer 31a, and the encapsulation layer 40a can fill the step portion 42a to avoid the action object in the oral cavity from directly contacting the second pattern layer 31a without passing through the first pattern layer 21a.

[0168] Of course, no structure can be provided at the step portion 42a, but the through hole 41a of the encapsulation layer 40a is positioned to only communicate with the first pattern layer 21a, and the encapsulation layer 40a is tightly fitted with the first pattern layer 21a to avoid the action object from entering the step portion 42a.

[0169] In the present example, the first pattern layer 21a and the second pattern layer 31a can exhibit different colors under the action of the agent, in other examples, the pattern layers can also exhibit different patterns, and the pattern layers can also be made of other materials, for example, the pattern layers are composed of starch-iodine inclusion complexes in the foregoing examples.

[0170] When the agent in the oral cavity does not enter the inside of the encapsulation layer 40a, no color display is observed on one side of the outer surface 1011a of the dental instrument body 101a.

[0171] When the agent in the oral cavity enters the inside of the encapsulation layer 40a, the agent first contacts the first pattern layer 21a, the first pattern layer 21a exhibits the first color, and the first color fills the first pattern layer 21a, that is, the first color fills the inner circle circle, at which time it can be indicated that the dental instrument 100a has been worn to the first time node.

[0172] Then the agent penetrates to the second pattern layer 31a, the second pattern layer 31a exhibits the second color, and the second color fills the second pattern layer 31a, that is, the second color fills the outer circle ring, and the first pattern layer 21a still maintains the first color, at which time it can be indicated that the dental instrument 100a has been worn to the second time node.

[0173] Other descriptions of the dental instrument 100a of the second specific example can refer to the descriptions of the foregoing or subsequent specific examples, which will not be described here.

[0174] In combination Figure 16 and Figure 17 is a schematic view of the dental instrument 100b of the third specific example.

[0175] In the third specific example, the first indicator 20b is located on the side of the second indicator 30b away from the teeth.

[0176] The first indicator 20b further comprises a first reaction layer 22b shielding the first pattern layer 21b, and the second indicator 30b further comprises a second reaction layer 32b shielding the second pattern layer 31b, and the agent controls the first reaction layer 22b and the second reaction layer 32b to be transparent in turn, thereby exposing the first pattern layer 21b and the second pattern layer 31b in turn.

[0177] In the present example, from the direction Y close to the cavity S to away from the cavity S, the second pattern layer 31b, the second reaction layer 32b, the first pattern layer 21b and the second reaction layer 22b are stacked and connected in turn.

[0178] The encapsulation layer 40b simultaneously encapsulates the second pattern layer 31b, the second reaction layer 32b, the first pattern layer 21b and the second reaction layer 22b.

[0179] The first reaction layer 22b covers the first pattern layer 21b, and the second reaction layer 32b covers the second pattern layer 31b. In this example, the first reaction layer 22b has the same size as the first pattern layer 21b, and the second reaction layer 32b has the same size as the second pattern layer 31b.

[0180] The first pattern layer 21b and the second pattern layer 31b are both circular in cross section, and the first pattern layer 21b and the second pattern layer 31b are concentric circles. The second pattern layer 31b has a larger size than the first pattern layer 21b, and the outer contour of the second pattern layer 31b is located outside the outer contour of the first pattern layer 21b.

[0181] In this example, the first reaction layer 22b and the second reaction layer 32b are formed of a material that becomes transparent when exposed to water, and the first pattern layer 21b and the second pattern layer 31b have a specific color. For example, the first pattern layer 21b has a first color, and the second pattern layer 31b has a second color. For details, refer to the first embodiment.

[0182] When the agent in the oral cavity does not enter the inside of the encapsulation layer 40b, no color display is observed on one side of the outer surface 1011b of the dental instrument body 101b.

[0183] When the agent in the oral cavity enters the inside of the encapsulation layer 40b, the agent first contacts the first reaction layer 22b. The first reaction layer 22b gradually becomes transparent and exposes the first pattern layer 21b. The first color of the first pattern layer 21b can be seen in the inner circle, which indicates that the dental instrument 100b has been worn to a first time point.

[0184] Then the agent penetrates to the second reaction layer 32b. The second reaction layer 32b gradually becomes transparent and exposes the second pattern layer 31b. The second color of the second pattern layer 31b can be seen in the outer circle, and the first pattern layer 21b still maintains the first color, which indicates that the dental instrument 100b has been worn to a second time point.

[0185] The other descriptions of the dental instrument 100b of the third specific example can refer to the descriptions of the foregoing or subsequent specific examples, which are not repeated here.

[0186] In combination Figure 18 And Figure 19 is a schematic view of a dental instrument 100c of a fourth specific example.

[0187] In the fourth specific example, the first indicator 20c is located on the side of the second indicator 30c away from the teeth.

[0188] The first indicator 20c comprises a first pattern layer 21c, a first reaction layer 22c shielding the first pattern layer 21c, and a first adsorption layer 23c connecting the first reaction layer 22c.

[0189] The second indicator 30c comprises a second pattern layer 31c, a second reaction layer 32c shielding the second pattern layer 31c, and a second adsorption layer 33c connecting the second reaction layer 32c.

[0190] When the first adsorption layer 23c reaches saturation state, the acting substance penetrates into the first reaction layer 22c, and the first reaction layer 22c becomes transparent to expose the first pattern layer 21c; when the second adsorption layer 33c reaches saturation state, the acting substance penetrates into the second reaction layer 32c, and the second reaction layer 32c becomes transparent to expose the second pattern layer 31c.

[0191] In the present example, the second pattern layer 31c, the second reaction layer 32c, the second adsorption layer 33c, the first pattern layer 21c, the first reaction layer 22c, and the first adsorption layer 23c are sequentially stacked and connected in the direction Y from the cavity S to the cavity S.

[0192] The encapsulation layer 40c simultaneously encapsulates the second pattern layer 31c, the second reaction layer 32c, the second adsorption layer 33c, the first pattern layer 21c, the first reaction layer 22c, and the first adsorption layer 23c, and the encapsulation layer 40c is located between the first adsorption layer 23c and the oral cavity to isolate the first reaction layer 22c and the oral cavity.

[0193] In the present example, the first adsorption layer 23c and the second adsorption layer 33c are both transparent layers, the cross sections of the first pattern layer 21c and the second pattern layer 31c are both circular, the first pattern layer 21c and the second pattern layer 31c are concentric circles, the size of the second pattern layer 31c is greater than the size of the first pattern layer 21c, and at this time, the outer contour of the second pattern layer 31c is located outside the outer contour of the first pattern layer 21c.

[0194] In the present example, the first reaction layer 22c and the second reaction layer 32c are formed of a material that becomes transparent when encountering water, and the first pattern layer 21c and the second pattern layer 31c have specific colors, for example, the first pattern layer 21c has a first color and the second pattern layer 31c has a second color, which can be specifically referred to the first embodiment.

[0195] When the acting substance in the oral cavity does not enter the inside of the encapsulation layer 40c, no color display is observed on one side of the outer surface 1011c of the dental instrument body 101c.

[0196] When the object in the oral cavity enters the inside of the encapsulation layer 40c, the object first contacts the first adsorption layer 23c, and when the first adsorption layer 23c reaches a saturation state, the object penetrates to the first reaction layer 22c, the first reaction layer 22c gradually becomes transparent to expose the first pattern layer 21c, that is, the first color of the first pattern layer 21c can be seen in the inner circle, at this time, it can be indicated that the dental instrument 100c has been worn to the first time node.

[0197] Then the object penetrates to the second adsorption layer 33c, and when the second adsorption layer 33c reaches a saturation state, the object penetrates to the second reaction layer 32c, the second reaction layer 32c gradually becomes transparent to expose the second pattern layer 31c, that is, the first color of the second pattern layer 31c can be seen in the outer circle, and the first pattern layer 21c still maintains the first color, at this time, it can be indicated that the dental instrument 100c has been worn to the second time node.

[0198] The other descriptions of the dental instrument 100c of the fourth specific example can refer to the descriptions of the foregoing or subsequent specific examples, which will not be described here.

[0199] In combination Figure 20 , a schematic view of the dental instrument 100d of the fifth specific example.

[0200] In the fifth specific example, the first indicator 20d and the second indicator 30d are arranged side by side along the tooth arrangement direction X, that is, the arrangement direction of the first indicator 20d and the second indicator 30d is parallel to the outer surface 1011d of the dental instrument body 101d.

[0201] The first indicator 20d only includes the first pattern layer 21d, the second indicator 30d only includes the second pattern layer 31d, and the first pattern layer 21d is connected to the second pattern layer 31d.

[0202] The encapsulation layer 40d simultaneously encapsulates the first pattern layer 21d and the second pattern layer 31d, and the encapsulation layer 40d has a through hole 41d communicating the oral cavity and the first pattern layer 21d, and the opening direction of the through hole 41d is parallel to the outer surface 1011d of the dental instrument body 101d.

[0203] In this example, the first pattern layer 21d isolates the channel through which the object contacts the second pattern layer 31d. For example, the first pattern layer 21d and the second pattern layer 31d include different starch-iodine inclusion compounds, and in other examples, the pattern layer can be made of other materials.

[0204] The first pattern layer 21d is composed of dextrin-iodine inclusion compound, and when the first pattern layer 21d does not show a pattern, the first pattern layer 21d shows red.

[0205] The second pattern layer 31d is composed of amylopectin-iodine inclusion complex, and the second pattern layer 31d exhibits purple red when the second pattern layer 31d does not exhibit a pattern.

[0206] When saliva in the oral cavity does not enter the inside of the encapsulation layer 40d, the red exhibited by the first pattern layer 31d and the purple red exhibited by the second pattern layer 21d can be observed simultaneously on one side of the outer surface 1011d of the dental instrument body 101d, and the red region and the purple red region are arranged in a straight line.

[0207] When saliva in the oral cavity enters the inside of the encapsulation layer 40d, the saliva first contacts the first pattern layer 21d, and the red of the first pattern layer 21d gradually fades until only the purple red exhibited by the second pattern layer 32d can be observed, at which time it can be indicated that the dental instrument 100d has been worn to a first time node.

[0208] Then the saliva penetrates to the second pattern layer 31d, and the purple red of the second pattern layer 31d gradually fades until it is completely faded, at which time it can be indicated that the dental instrument 100d has been worn to a second time node.

[0209] Other descriptions of the dental instrument 100d of the fifth specific example can refer to the descriptions of the foregoing or subsequent specific examples, and will not be described here.

[0210] It should be noted that the indicator in the second embodiment can also be other structures in the first embodiment, and is not limited to the above description.

[0211] In combination Figure 21 and Figure 22 are schematic diagrams of the indicator 60 and the dental instrument 100 of the third embodiment of the present application.

[0212] In the third embodiment, the indicator 60 includes a pattern layer 61 and a scale 70, and the pattern layer 61 generates a change region L under the action of an agent in the oral cavity.

[0213] The scale 70 is used to indicate the position information of the change region L.

[0214] Here, it is assumed that the pattern layer 61 forms an observation region N, and when the dental instrument 100 is worn in the oral cavity, the pattern layer 61 changes so that the observation region N includes a change region L and an unchanged region M, and the change region L is, for example, a color change region, a color fading region, etc.

[0215] As the wearing time of the dental instrument 100 is prolonged, the boundary position A between the change region L and the unchanged region M changes, and the scale 70 is used to indicate the position information of the boundary position A, that is, the wearing time of the dental instrument 100 can be indicated by the scale 70.

[0216] In other words, the present embodiment can indicate the wearing time of the dental appliance 100 in real time by providing the scale 70 cooperating with the pattern layer 61.

[0217] In the present embodiment, the indicator 60 is installed on the outer surface 1011 of the dental appliance body 101, and the pattern layer 61 changes color along the first direction X to generate the change area L, the first direction X is parallel to the outer surface 1011, and the position information of the change area L is convenient for observation and indication.

[0218] It should be noted that "the pattern layer 61 changes color along the first direction X" means that the observed pattern layer 61 changes color along the first direction X, and the actual penetration direction of the agent in the oral cavity can be the first direction X or a direction perpendicular to the first direction X, such as the direction from far away from the cavity S to close to the cavity S (i.e. the opposite direction of the Y direction).

[0219] In the present embodiment, the first direction X is taken as an example for the tooth arrangement direction.

[0220] The scale 70 extends along the first direction X, and the scale has a mark 71 indicating the junction position A of the change area L and the unchanged area M, the mark 71 refers to the arrow area in Figure 17 .

[0221] Here, along the first direction X, a plurality of marks 71 are formed on the scale 70, and the plurality of marks 71 are used to indicate a plurality of different wearing times.

[0222] For example, four marks 71 are sequentially formed on the scale 70 along the first direction X, and the four marks 71 sequentially indicate wearing times of 3 days, 7 days, 14 days and 28 days, so that the wearing time of the dental appliance 100 can be determined by observing the relationship between the mark 71 and the junction position A, and the indication process of the wearing time is more simple and direct.

[0223] In addition, the scale 70 is connected to the pattern layer 61 and located at the side of the pattern layer 61, and in other examples, the scale 70 can be located above the pattern layer 61, i.e. the scale 70 is located on the side of the pattern layer 61 away from the outer surface 1011 of the dental appliance body 101, of course, in other embodiments, the scale 70 and the pattern layer 61 can also be distributed at the outer surface 1011 of the dental appliance body 101.

[0224] It can be understood that the scale 70 can also be in other forms, as long as it can indicate the wearing time of the dental appliance 100.

[0225] In the present embodiment, the indicator 60 further comprises an encapsulation layer 80 encapsulating at least the pattern layer 61, and the encapsulation layer 80 has a through hole 81 communicating the pattern layer 61 and the oral cavity, and the scale 70 can be located outside or inside the encapsulation layer 80.

[0226] Next, various specific examples of the dental instrument 100 with the indicator 60 in the third embodiment will be described.

[0227] In the first specific example, the indicator 60 includes only one pattern layer 61, which is exemplified by a starch-iodine clathrate compound that gradually fades in the presence of salivary amylase in saliva, and in other examples, the pattern layer can be made of other materials. Figure 22 The encapsulation layer 80 encapsulates the pattern layer 61, and the through hole 81 in the encapsulation layer 80 has an opening direction that is the first direction X.

[0228] The pattern layer 61 is composed of a dextrin-iodine clathrate compound, and when the pattern layer 61 does not exhibit a pattern, the pattern layer 61 exhibits a red color.

[0229] When saliva in the oral cavity does not enter the inside of the encapsulation layer 80, the entire observation area N formed by the pattern layer 61 can be observed to be red on one side of the outer surface 1011 of the dental instrument body 101.

[0230] When saliva in the oral cavity enters the inside of the encapsulation layer 80, the saliva contacts the pattern layer 61, and the red color of the pattern layer 61 gradually fades. The area where the color fades is the change area L, and the area where the color does not fade is the unchanged area M. The change area L and the unchanged area M form an interface position A. At this time, the position information of the interface position A can be read according to the marks 71 on the scale 70, and the position information can indicate the wearing time of the dental instrument 100.

[0231] In the first specific example, the indicator 60 includes only one pattern layer 61, which is exemplified by a starch-iodine clathrate compound that gradually fades in the presence of salivary amylase in saliva, and in other examples, the pattern layer can be made of other materials.

[0232] Figure 23 The dental instrument 100a in the second specific example is shown schematically. For ease of description, the same or similar structures in this example as in the first specific example are denoted by the same or similar reference numerals, and the same applies hereinafter.

[0233] In the second specific example, the pattern layer of the indicator 60a includes a first pattern layer 61a and a second pattern layer 62a that are connected together, which are exemplified by starch-iodine clathrate compounds, and in other examples, the pattern layer can be made of other materials.

[0234] The encapsulation layer 80a encapsulates the first pattern layer 61a and the second pattern layer 62a, and the through hole 81a in the encapsulation layer 80a has an opening direction that is the first direction X.

[0235] The first pattern layer 61a is composed of a dextrin-iodine clathrate compound, and when the pattern layer 61a does not exhibit a pattern, the pattern layer 61a exhibits a red color.

[0236] ​The second pattern layer 62a is composed of a branched amylose-iodine inclusion compound, and the second pattern layer 62a exhibits a purple red color when the second pattern layer 62a does not exhibit a pattern.

[0237] When the saliva in the oral cavity does not enter the inside of the encapsulation layer 80a, the red color exhibited by the first pattern layer 61a and the purple red color exhibited by the second pattern layer 62a can be observed on one side of the outer surface 1011a of the dental appliance body 101a, and the entire observation area N is a red color area and a purple red color area arranged in a straight line.

[0238] When the saliva in the oral cavity enters the inside of the encapsulation layer 80a, the saliva penetrates in the first direction X to sequentially contact the first pattern layer 61a and the second pattern layer 62a, the faded color area in the entire observation area N is the change area L, and the area without faded color is the unchanged area M, and the interface position A is formed between the change area L and the unchanged area M, at this time, the position information of the interface position A can be read according to the mark 71a on the scale 70a, and the position information can indicate the wearing time of the dental appliance 100a.

[0239] Here, since there are two pattern layers with different colors, the color change of the pattern layer also has a certain indication effect on the wearing time, and the present example can simultaneously indicate the wearing time through color change and scale 70a reading, and the indication effect is better.

[0240] The other descriptions of the dental appliance 100a of the second specific example are described in the foregoing or the following specific examples, and will not be repeated here.

[0241] In combination Figure 24 and Figure 25 A schematic view of a dental appliance 100b of a third specific example is shown.

[0242] In the third specific example, the indicator 60b only includes one pattern layer 61b, which is taken as a branched amylose-iodine inclusion compound in this example, and the cross section of the pattern layer 61b is circular, and in other examples, the pattern layer 61b can be made of other materials.

[0243] The encapsulation layer 80b encapsulates the pattern layer 61b, and the opening direction of the through hole 81b on the encapsulation layer 80b is the direction Y from close to the cavity S to far from the cavity S, and the through hole 81b is arranged corresponding to the center C of the pattern layer 61b, at this time, the saliva first contacts the center C of the pattern layer 61b.

[0244] The pattern layer 61b is composed of a dextrin-iodine inclusion compound, and the pattern layer 61b exhibits a red color when the pattern layer 61b does not exhibit a pattern.

[0245] When the saliva in the oral cavity does not enter the inside of the encapsulation layer 80b, the entire observation area N formed by the pattern layer 61b on one side of the outer surface 1011b of the dental appliance body 101b is red, and the observation area N is circular.

[0246] When the saliva in the oral cavity enters the inside of the encapsulation layer 80b, the saliva contacts the center C of the pattern layer 61b, and the red color exhibited by the pattern layer 61b gradually fades from the center C radially outward. The area in which the color fades is the change area L, and the area in which the color does not fade is the unchanged area M. The change area L and the unchanged area M form an interface position A. At this time, the position information of the interface position A can be read according to the mark 71b on the scale 70b, and the position information can indicate the wearing time of the dental appliance 100b.

[0247] The dental appliance 100b of the third specific example is described above or below.

[0248] It should be noted that the indicator in the third embodiment can also be other structures in the first and second embodiments, and is not limited to the above description.

[0249] In addition, the new specific examples can be formed by mutual reference and learning between each embodiment, and the new specific examples are all within the protection scope of the present application.

The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be combined appropriately to form other embodiments that can be understood by those skilled in the art.
