[0027] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0028] Combination Figure 1 and Figure 2 , is a schematic diagram of a dental assembly 300 according to an embodiment of the present invention.

[0029] The dental assembly 300 includes a first shell-shaped dental appliance 100 and a second shell-shaped dental appliance 200 . One of the first shell-shaped dental appliance 100 and the second shell-shaped dental appliance 200 is disposed corresponding to the upper teeth, and the other of the first shell-shaped dental appliance 100 and the second shell-shaped dental appliance 200 is disposed corresponding to the lower teeth.

[0030] For ease of explanation, here it is taken as an example that the first shell-shaped dental appliance 100 is set corresponding to the mandibular teeth and the second shell-shaped dental appliance 200 is set corresponding to the maxillary teeth. However, in other embodiments, the first shell-shaped dental appliance 100 can be set corresponding to the maxillary teeth, and the second shell-shaped dental appliance 200 can be set corresponding to the mandibular teeth.

[0031] The first shell-shaped dental instrument 100 includes a first shell-shaped dental instrument body 10 and a first action portion 12 located on a first occlusal surface 11 of the first shell-shaped dental instrument body 10 . The second shell-shaped dental instrument 200 includes a second shell-shaped dental instrument body 20 and a second action portion 22 located on a second occlusal surface 21 of the second shell-shaped dental instrument body 20 .

[0032] The first action portion 12 includes a first guide portion 121 and a first jaw pad portion 122 that are spaced apart, and the second action portion 22 includes a second guide portion 221 and a second jaw pad portion 222. When the maxillary teeth and the mandibular teeth are in a fully occluded state, the first guide portion 121 and the second guide portion 221 interact with each other to adjust the jaw position relationship, and the first jaw pad portion 122 and the second jaw pad portion 222 interact with each other to be fixed.

[0033] Here, "the first guide portion 121 and the second guide portion 221 interact with each other to adjust the jaw position relationship" means that the corrective force generated by the interaction between the first guide portion 121 and the second guide portion 221 can be used to adjust the jaw position relationship, including maxillary jaw position adjustment and mandibular jaw position adjustment; "the first jaw pad portion 122 and the second jaw pad portion 222 interact with each other to be retained" means that the first jaw pad portion 122 and the second jaw pad portion 222 are retained with each other to maintain the jaw position relationship of the upper and lower jaws. This embodiment can induce adjustment of the upper and lower jaw position relationship while opening the bite.

[0034] In this embodiment, the first shell-shaped dental instrument 100 includes a first jaw pad portion 122, and the second shell-shaped dental instrument 200 includes a second jaw pad portion 222. When the occlusal height is opened to a certain extent, the height of the single jaw pad portion can be reduced by arranging jaw pad portions on both the upper and lower teeth, thereby improving the strength of the jaw pad portion and preventing the jaw pad portion from being bitten down, thereby improving the stability of the entire dental assembly 300.

[0035] In addition, the first guide portion 121 and the first jaw pad portion 122 of the present embodiment are arranged at intervals. On the one hand, the freedom of design of the first guide portion 121 and the first jaw pad portion 122 can be improved. On the other hand, compared with the form in which the first guide portion 121 and the first jaw pad portion 122 are connected to each other, the first guide portion 121 and the first jaw pad portion 122 arranged at intervals can effectively reduce the length of the first action portion 12 continuously extending in the mesiodistal direction, thereby improving the strength of the first action portion 12, thereby improving the stability of the entire dental component 300.

[0036] In this embodiment, continue to combine Figure 1 and Figure 2 The first action portion 12 is located in the posterior tooth area of ​​the first occlusal surface 11, and the second action portion 22 is located in the posterior tooth area of ​​the second occlusal surface 21. The left and right posterior tooth areas of the mandibular teeth are both provided with the first action portion 12, and the left and right posterior tooth areas of the maxillary teeth are both provided with the second action portion 22 to improve the stability of jaw position adjustment.

[0037] The first shell-shaped dental instrument body 10 includes a first cavity S1 for accommodating teeth, the first action part 12 includes a first chamber S1' connected to the first cavity S1, the second shell-shaped dental instrument body 20 includes a second cavity S2 for accommodating teeth, and the second action part 22 includes a second chamber S2' connected to the second cavity S2.

[0038] Here, the first action portion 12 and the first shell-shaped dental instrument body 10 may be integrally formed, and similarly, the second action portion 22 and the second shell-shaped dental instrument body 20 may also be integrally formed, but the present invention is not limited thereto.

[0039] In a specific embodiment, the first shell-shaped dental device 100 includes a first filling portion filled in the first cavity S1', and the second shell-shaped dental device 200 includes a second filling portion filled in the second cavity S2', so that the strength of the first action portion 12 and the second action portion 22 can be improved to avoid being bitten down, but the present invention is not limited thereto.

[0040] In this embodiment, continue to combine Figure 1 and Figure 2 The first jaw pad portion 122 protrudes out of the first occlusal surface 11 toward the opposing jaw, and the second jaw pad portion 222 protrudes out of the second occlusal surface 21 toward the opposing jaw.

[0041] The first guide portion 121 protrudes out of the first occlusal surface 11 toward the opposing jaw, and the second guide portion 221 protrudes out of the second occlusal surface 21 toward the opposing jaw.

[0042] That is to say, the first jaw pad portion 122, the second jaw pad portion 222, the first guide portion 121 and the second guide portion 221 all protrude out of the corresponding occlusal surface settings, that is, the first jaw pad portion 122, the second jaw pad portion 222, the first guide portion 121 and the second guide portion 221 are not arranged in contact with the teeth, wherein the protruding first jaw pad portion 122 and the second jaw pad portion 222 can reduce the height of each jaw pad portion to improve the strength of the first jaw pad portion 122 and the second jaw pad portion 222, and the protruding first guide portion 121 and the second guide portion 221 can achieve a stable fit between the first guide portion 121 and the second guide portion 221.

[0043] In this embodiment, in the mesiodistal direction, the first guide portion 121 has a first guide surface 1211, and the second guide portion 221 has a second guide surface 2211. The first guide surface 1211 and the second guide surface 2211 interact with each other. When the maxillary teeth and the mandibular teeth are in a fully occluded state, the first guide surface 1211 and the second guide surface 2211 are matched with each other in an inclined surface.

[0044] That is to say, the first guide surface 1211 and the second guide surface 2211 are both inclined, and the inclined first guide surface 1211 and the second guide surface 2211 can realize the guidance between the first guide part 121 and the second guide part 221, avoiding collision between the first guide part 121 and the second guide part 221, and the first guide surface 1211 and the second guide surface 2211 abut against each other to induce adjustment of the upper and lower jaw position relationship.

[0045] In this embodiment, the first jaw pad portion 122 includes a first retaining surface 1221 away from the first occlusal surface 11, and the second jaw pad portion 222 includes a second retaining surface 2221 away from the second occlusal surface 21. The first retaining surface 1221 interacts with the second retaining surface 2221. When the maxillary teeth and the mandibular teeth are in a fully occluded state, the first retaining surface 1221 and the second retaining surface 2221 are concave-convex fit.

[0046] Here, the concavo-convex fit between the first fixing surface 1221 and the second fixing surface 2221 can improve the stability of the fit between the first fixing surface 1221 and the second fixing surface 2221. In addition, the concavo-convex fit structure between the two can further improve the strength of the first jaw pad 122 and the second jaw pad 222.

[0047] The height of the first jaw pad 122 protruding from the first occlusal surface 11 is a first height, and the height of the second jaw pad 222 protruding from the second occlusal surface 21 is a second height. The range of the first height and the second height is 1 / 5-4 / 5 of the open occlusal height.

[0048] Here, the specific parameters of the first height and the second height can be determined according to actual conditions, but it is necessary to ensure that the sum of the first height and the second height is the open bite height, and the first height and the second height cannot be too high or too low to avoid affecting the strength of a single jaw pad due to excessive height.

[0049] In addition, the open bite height decreases with the progress of the correction, that is, the open bite height of the N+Mth correction step is less than the open bite height of the Nth step, M is an integer not less than 1. During the entire correction process, the open bite height can be reduced multiple times. Of course, it can also be reduced only once, depending on actual needs.

[0050] In other embodiments, one of the first jaw pad portion 122 and the second jaw pad portion 222 includes a plurality of adjustment portions, and the other includes a retaining portion, and the retaining portion interacts with different adjustment portions to adjust the jaw position relationship.

[0051] Here, the adjustment part and the fixing part can be located on the first fixing surface 1221 of the first jaw pad 122 and the second fixing surface 2221 of the second jaw pad 222. When the first jaw pad 122 and the second jaw pad 222 contact each other, the fixing part can be limited to different adjustment parts to achieve different jaw position relationships.

[0052] That is to say, in addition to maintaining the jaw position relationship of the upper and lower jaws, the first jaw pad 122 and the second jaw pad 222 can also adjust the jaw position relationship in special scenarios. For example, when the first guide portion 121 and the second guide portion 221 no longer play a role in adjusting the jaw position relationship, the first jaw pad 122 and the second jaw pad 222 can assist in adjusting the jaw position relationship.

[0053] In addition, unlike the first guide portion 121 and the second guide portion 221 which achieve jaw position adjustment through the cooperation of inclined surfaces, the first jaw pad portion 122 and the second jaw pad portion 222 achieve jaw position adjustment through the mutual engagement of the adjustment portion and the retention portion.

[0054] It is understandable that under different requirements, the jaw position adjustment can be achieved by selecting the first guide portion 121 and the second guide portion 221 , or the first jaw pad portion 122 and the second jaw pad portion 222 .

[0055] In this embodiment, a gap P is formed between the first jaw pad portion 122 and the first guide portion 121 , and the second guide portion 221 extends into the gap P when the maxillary teeth and the mandibular teeth are in a fully occluded state.

[0056] That is to say, the "first guide portion 121 and the first jaw pad portion 122 that are spaced apart" in this embodiment refers to a gap P formed between the first jaw pad portion 122 and the first guide portion 121, and the gap P can be used to accommodate the second guide portion 221, thereby increasing the contact area between the second guide portion 221 and the first guide portion 121, but the present invention is not limited to this. The second guide portion 221 may also extend to other areas and cooperate with the first guide portion 121.

[0057] The first occlusal surface 11 includes a middle occlusal surface 111 which is surrounded to form a notch P, and the middle occlusal surface 111 is in contact with the corresponding tooth surface.

[0058] Here, the first occlusal surface 11 is entirely arranged to fit the tooth surface, and the area of ​​the first occlusal surface 11 between the first guide portion 121 and the first jaw pad portion 122 is the middle occlusal surface 111 , that is, the middle occlusal surface 111 also fits the tooth surface at this time.

[0059] At this time, the gap P is substantially formed by three sides: the middle occlusal surface 111 , the side surface of the first guide portion 121 facing the first jaw pad portion 122 , and the side surface of the first jaw pad portion 122 facing the first guide portion 121 .

[0060] It can be understood that the setting of the notch P is equivalent to cutting off the first guide portion 121 and the first jaw pad portion 122 in the mesiodistal direction, which can effectively reduce the length of the first action portion 12 continuously extending in the mesiodistal direction, thereby improving the strength of the first action portion 12, thereby improving the stability of the entire dental assembly 300.

[0061] In this embodiment, the second guide portion 221 and the second jaw pad portion 222 are connected to each other.

[0062] That is to say, the second guide portion 221 and the second jaw pad portion 222 of the second action portion 22 are a continuous structure, that is, there is no gap between the second guide portion 221 and the second jaw pad portion 222 .

[0063] In other embodiments, the second guide portion 221 and the second jaw pad portion 222 in the second action portion 22 may also be spaced apart, that is, the second action portion 22 may be similar to the first action portion 12, and a gap may also be formed between the second guide portion 221 and the second jaw pad portion 222. The technical effect thereof may refer to the description of the first guide portion 121 and the first jaw pad portion 122 spaced apart as described above.

[0064] In addition, the second jaw pad portion 222 protrudes out of the second guide portion 221 toward the opposing jaw convexity, and the first jaw pad portion 122 protrudes out of the first guide portion 121 toward the opposing jaw convexity.

[0065] That is to say, in the direction of the maxillary teeth toward the mandibular teeth, the height of the second guide portion 221 is greater than the height of the second jaw pad portion 222. At this time, when the maxillary teeth and the mandibular teeth are in a fully occluded state, the first jaw pad portion 122 and the second jaw pad portion 222 contact each other. At the same time, the second guide portion 221 with a relatively high height can protrude from the second jaw pad portion 222 and enter the gap P, and then contact the first guide portion 121.

[0066] In addition, in the direction from the maxillary teeth to the mandibular teeth, the height of the first guide portion 121 is greater than the height of the first jaw pad portion 122, and the first guide portion 121 also protrudes beyond the first jaw pad portion 122, which can effectively increase the contact area between the first guide portion 121 and the second guide portion 221, thereby improving the effect of jaw position adjustment.

[0067] Of course, in other embodiments, the first guide portion 121 may not protrude from the first jaw pad portion 122, but only the second guide portion 221 protrudes from the second jaw pad portion 222, or the second guide portion 221 may not protrude from the second jaw pad portion 222, but only the first guide portion 121 protrudes from the first jaw pad portion 122.

[0068] In this embodiment, the first action portion 12 and the second action portion 22 may have various matching forms.

[0069] For example, combined with Figure 1 and Figure 2The first action portion 12 is arranged corresponding to the mandibular teeth, and the second action portion 22 is arranged corresponding to the maxillary teeth. The first guide portion 121 is located at the distal side of the first jaw pad portion 122, and the second guide portion 221 is located at the distal side of the second jaw pad portion 222. The first guide surface 1211 is located at the distal side of the first guide portion 121, and the second guide surface 2211 is located at the mesial side of the second guide portion 221. At this time, the first guide surface 1211 and the second guide surface 2211 interact with each other to realize mandibular advancement, and at this time, a gap P is formed between the first guide portion 121 and the first jaw pad portion 122.

[0070] Alternatively, the first action portion 12 is arranged corresponding to the mandibular teeth, and the second action portion 22 is arranged corresponding to the maxillary teeth. The first guide portion 121 is located at the distal side of the first jaw pad portion 122, and the second guide portion 221 is located at the distal side of the second jaw pad portion 222. The first guide surface 1211 is located at the mesial side of the first guide portion 121, and the second guide surface 2211 is located at the distal side of the second guide portion 221. At this time, the first guide surface 1211 and the second guide surface 2211 interact with each other to achieve mandibular retraction, and at this time, a gap P can be formed between the second guide portion 221 and the second jaw pad portion 222.

[0071] Alternatively, the first action portion 12 is arranged corresponding to the mandibular teeth, and the second action portion 22 is arranged corresponding to the maxillary teeth. The first guide portion 121 is located at the mesial side of the first jaw pad portion 122, and the second guide portion 221 is located at the mesial side of the second jaw pad portion 222. The first guide surface 1211 is located at the distal side of the first guide portion 121, and the second guide surface 2211 is located at the mesial side of the second guide portion 221. At this time, the first guide surface 1211 and the second guide surface 2211 interact with each other to achieve mandibular retraction, and at this time, a gap P can be formed between the first guide portion 121 and the first jaw pad portion 122.

[0072] Alternatively, the first action portion 12 is arranged corresponding to the mandibular teeth, and the second action portion 22 is arranged corresponding to the maxillary teeth. The first guide portion 121 is located at the mesial side of the first jaw pad portion 122, and the second guide portion 221 is located at the mesial side of the second jaw pad portion 222. The first guide surface 1211 is located at the mesial side of the first guide portion 121, and the second guide surface 2211 is located at the distal side of the second guide portion 221. At this time, the first guide surface 1211 and the second guide surface 2211 interact with each other to achieve mandibular retraction, and at this time, a gap P can be formed between the second guide portion 221 and the second jaw pad portion 222.

[0073] In this embodiment, combined with Figure 3 , a feature part may be formed on the dental model first, and then the first shell-shaped dental appliance 100 and the second shell-shaped dental appliance 200 may be formed by hot pressing film forming.

[0074] Specifically, a first characteristic part 42 and a second characteristic part 43 that are spaced apart can be formed on the mandibular dental model, and then the first shell-shaped dental instrument 100 formed has a first guide portion 121 and a first jaw pad portion 122 that are spaced apart; an integral third characteristic part 44 can be formed on the maxillary dental model, and then the second shell-shaped dental instrument 200 formed has a second guide portion 221 and a second jaw pad portion 222 that are connected to each other.

[0075] In this embodiment, the first jaw pad portion 122 and / or the second jaw pad portion 222 are inclined along the buccal and lingual sides to increase the contact area between the first jaw pad portion 122 and the second jaw pad portion 222 when the maxillary teeth and the mandibular teeth are in a fully occluded state.

[0076] Here, combined Figure 4 In the prior art, when the jaw pad 30 is subjected to a vertical bite force, if the jaw pad 30 extends to the inclined side of the tooth, the bite force is borne by the inclined surface, and the supporting effect of the inclined surface is unstable and prone to lateral sliding and collapse. Therefore, it is necessary to set the width W1 of the jaw pad 30 to be smaller than the width W2 of the corresponding tooth.

[0077] In the buccal-lingual direction (i.e., in the direction from the buccal surface to the lingual surface), the maxillary teeth and the mandibular teeth are normally misaligned with each other. If the jaw pad 30 is set perpendicular to the occlusal surface, the contact area between the two jaw pads corresponding to the upper and lower teeth will be relatively small, making the occlusion unstable.

[0078] In this embodiment, combined with Figure 5 The first jaw pad portion 122 and / or the second jaw pad portion 222 are inclined along the buccal and lingual sides. Here, taking the first jaw pad portion 122 inclined toward the buccal side and the second jaw pad portion 222 inclined toward the lingual side as an example, when the maxillary teeth and the mandibular teeth are in a fully occluded state, the contact area between the first jaw pad portion 122 and the second jaw pad portion 222 is increased compared to the prior art, thereby achieving stable contact between the first jaw pad portion 122 and the second jaw pad portion 222.

[0079] In addition, combined Figure 6 Since the first jaw pad portion 122 and the second jaw pad portion 222 are mainly subjected to the vertical occlusal force, if the first jaw pad portion 122 and the second jaw pad portion 222 are inclined, the first jaw pad portion 122 and the second jaw pad portion 222 are easily bitten down when receiving the vertical occlusal force. Therefore, the dental component 300 of this embodiment also includes reinforcing ribs 1222, 2222 located on the inclined surface.

[0080] Specifically, at this time, a first reinforcing rib 1222 may be provided on the buccal surface of the first jaw pad portion 122 , and a second reinforcing rib 2222 may be provided on the lingual surface of the second jaw pad portion 222 .

[0081] Of course, in order to improve the overall strength and stability of the dental assembly 300 , reinforcing ribs may also be provided at other areas of the first jaw pad portion 122 , the second jaw pad portion 222 , and the first guide portion 121 , the second guide portion 221 .

[0082] In summary, the first shell-shaped dental instrument 100 of the utility model includes a first jaw pad portion 122, and the second shell-shaped dental instrument 200 includes a second jaw pad portion 222. When the occlusal height is opened to a certain extent, the height of the single jaw pad portion can be reduced by arranging jaw pad portions on both the upper and lower teeth, thereby improving the strength of the jaw pad portion and preventing the jaw pad portion from being bitten down, thereby improving the stability of the entire dental assembly 300.

[0083] In addition, the first guide portion 121 and the first jaw pad portion 122 are arranged at intervals. On the one hand, the freedom of design of the first guide portion 121 and the first jaw pad portion 122 can be improved. On the other hand, compared with the form in which the first guide portion and the first jaw pad portion are connected to each other, the first guide portion 121 and the first jaw pad portion 122 are arranged at intervals. The length of the first action portion 12 continuously extending in the mesiodistal direction can be effectively reduced, thereby improving the strength of the first action portion 12, thereby improving the stability of the entire dental component 300.
