Description
Technical Field
The present invention relates to a mouthpiece for correcting teeth, and more particularly, to a mouthpiece for correcting malocclusions by occlusion of teeth.
Background
In addition to the effects of chewing and pronunciation, the irregular teeth may cause oral health problems such as tooth decay, periodontal disease, abnormal wear of teeth, etc. and more people perform teeth correction for the beauty and health of teeth.
Currently, the common way of straightening teeth is to stick an appliance to the surface of each tooth, then install a straightening wire to each appliance, and then pull the straightening wire to change the arrangement position of the teeth, thereby changing the overall appearance and malocclusion of the teeth, however, at present, both the appliances and the straightening wires are stuck to the outer side of the teeth, so that both the appliances and the straightening wires are located on the buccal side of the teeth of the patient, thereby not only affecting the beauty of the teeth of the patient, but even the appliances and the straightening wires easily scratch the inner side of the cheek to cause the bleeding due to the broken skin.
In order to avoid the loss caused by using the orthodontic device and the orthodontic wire to straighten teeth, some patients select a transparent tooth socket with beautiful appearance to straighten teeth, wherein when the transparent tooth socket is arranged on an arch, the transparent tooth socket applies horizontal force to the side surface of the arch to adjust the teeth to the expected position, but if the prior transparent tooth socket is not provided with additional components (such as a spring and the orthodontic wire), the transparent tooth socket difficultly generates longitudinal force to the arch to straighten the teeth, and further the transparent tooth socket difficultly straightens the malocclusion.
Disclosure of Invention
The invention mainly aims to solve the problem of malocclusion between upper and lower dental arches by using a correction force which is approximately vertical to an occlusal surface of a tooth socket when the upper and lower dental arches are occluded.

Detailed Description
The invention will be further described with reference to specific embodiments and drawings, the advantages and features of which will become apparent as the description proceeds.
Referring to fig. 1A to 1C, in a first preferred embodiment, the dental mouthpiece 1 of the present invention is used for correcting an arch 10 of a patient, the arch 10 has a plurality of teeth 11 (e.g., incisors, canines, and molars) with different shapes, and each of the teeth 11 of the arch 10 has an occlusal surface 12 on a side away from gingiva, and each of the occlusal surfaces 12 has a height different from the height of each of the occlusal surfaces 12, so that the arch 10 can be set as an upper arch or a lower arch of the patient.
As shown in the figure, the dental mouthpiece 1 has two elastic arms 20, one of the two elastic arms 20 is integrally formed with the other elastic arm 20 to form an arch-shaped elastic arm 21, the outer side surface of the arch-shaped elastic arm 21 forms a correction contour 22 corresponding to the texture of the inner side surface of the orthodontic arch 10, and the size of the arch-shaped elastic arm 21 is smaller than the size of the orthodontic arch 10, and the correction contour 22 of the arch-shaped elastic arm 21 is the same as the inner side contour of the orthodontic arch 10, wherein the opposite ends of the arch-shaped elastic arm 21 respectively and integrally extend to form an extension block 30 and a correction block 40 formed by extending the extension block 30, one side surface of the correction block 40 forms a contact surface 41 corresponding to the occlusal surface 12, and one side of the opposite contact surface 41 forms a correction plane 42 presenting a smooth appearance.
In this embodiment, the shell 1 is assembled to the orthodontic arch 10 such that the arch-shaped resilient arms 21 are positioned on the lingual side of the orthodontic arch 10 (i.e., on the inner side of the orthodontic arch 10) with one of the extension blocks 30 and one of the extension blocks 40 both positioned at one end of the orthodontic arch 10 and the other extension block 30 and one of the extension blocks 40 both positioned at the other end of the orthodontic arch 10, as shown in FIG. 1B, the arch-shaped resilient arms 21 do not exceed the occlusal surface 12 at the lowest height position in the orthodontic arch 10, with the extension blocks 30 at the end away from the resilient arms 20 at the same height position as the occlusal surface 12 at the highest height position in the orthodontic arch 10, and, when the shell 1 is assembled to the orthodontic arch 10, the orthodontic profiles 22 of the arch-shaped resilient arms 21 contact the inner side of the orthodontic arch 10 and the contact surfaces 41 of the extension blocks 40 contact the occlusal surface 12 at the highest height position in the orthodontic arch 10, the height position of the orthodontic block 40 is made to exceed the height position of each occlusal surface 12, wherein the arch-shaped resilient arms 21 are not deformed by the orthodontic arch 10 when the mouthpiece 1 is assembled to the orthodontic arch 10 because the orthodontic profile 22 is formed to have the same profile as the inner profile of the orthodontic arch 10.
Subsequently, as shown in fig. 1D, the orthodontic arch 10 is engaged with an opposite arch 50 on one side of the orthodontic arch 10 so that a part of teeth of the opposite arch 50 do not contact the occlusal surface 12 of the orthodontic arch 10 and the remaining teeth of the opposite arch 50 contact the orthodontic plane 42 of the orthodontic block 40, and the orthodontic block 40 forms a orthodontic force P1 almost perpendicular to the occlusal surface 12 to the orthodontic teeth 11 so that a part of the teeth 11 of the orthodontic arch 10 can be corrected by the orthodontic force P1 to improve the problem of malocclusion between the orthodontic arch 10 and the opposite arch 50. in this embodiment, when the orthodontic arch 10 is set as the lower arch of the patient, the opposite arch 50 is set as the upper arch, and when the orthodontic arch 10 is set as the upper arch of the patient, the arch 50 is set as the lower arch.
In this embodiment, the orthodontic arch 10 is such that the occlusal surface 12 of the molar tooth is higher than the occlusal surface 12 of the other tooth 11, and when the dental brace 1 is assembled to the orthodontic arch 10, the orthodontic block 40 is positioned above the molar tooth of the orthodontic arch 10, and when the orthodontic arch 50 is engaged with the orthodontic arch 10, the molar tooth of the orthodontic arch 10 is orthodontic by the orthodontic force P1 without the incisors and canines of the orthodontic arch 10 coming into contact with the occlusal surfaces 12 of both the incisors and canines of the orthodontic arch 10, and the molar tooth of the orthodontic arch 50 comes into contact with the orthodontic plane 42 of the orthodontic block 40, so that the molar tooth of the orthodontic arch 10 is orthodontic force-corrected by the orthodontic force P1, and the molar tooth of the orthodontic arch 10 is gradually lowered in height position, so that the occlusal surface 12 of the molar tooth of the orthodontic arch 10 is brought into close alignment with the occlusal surfaces 12 of the other canine tooth 11 (e.g., incisors and canines) of the orthodontic arch 10, so that the orthodontic arch 10 can be surely engaged with the orthodontic arch 50, and the arch 10, each tooth 11 of the orthodontic arch 10 can contact the teeth of the opposing arch 50 one-to-one.
However, the corrective force P1 is only for convenience of illustration, i.e. the relative position between the resilient arms 20 and the corrective block 40 can be changed according to which occlusal surface 12 of one tooth 11 is located at the highest level, so that when the dental mouthpiece 1 is installed in the corrective arch 10, the corrective block 40 can contact the incisors or canines of the corrective arch 10 to correct the incisors or canines of the corrective arch 10.
Referring to fig. 2A and 2B, in the second preferred embodiment, the difference from the first preferred embodiment is that the shape of the arch-shaped elastic arm 21 is larger than the orthodontic arch 10, and the orthodontic profile 22 is located on the inner side surface of the arch-shaped elastic arm 21 and is similar to the texture of the outer side surface of the orthodontic arch 10, wherein the orthodontic profile 22 of the arch-shaped elastic arm 21 is smaller than the outer side profile of the orthodontic arch 10, in addition, the extension block 30 is integrally formed on the elastic arm 20 as in the first preferred embodiment, and the orthodontic block 40 is integrally formed on the extension block 30 as in the first preferred embodiment, and the structural design of the extension block 30 and the orthodontic block 40 is the same as in the first preferred embodiment, so the description thereof will be omitted.
In this embodiment, when the mouthpiece 1 is installed in the orthodontic arch 10, the arch-shaped resilient arms 21 are located on the buccal side of the orthodontic arch 10 (on the outer side of the orthodontic arch 10), and one of the extension blocks 30 and one of the correction blocks 40 are located on one end of the orthodontic arch 10, and the other extension block 30 and one of the correction blocks 40 are located on the other end of the orthodontic arch 10, as shown in the drawings, the arch-shaped resilient arms 21 also do not exceed the occlusal surface 12 of the lowest height position of the orthodontic arch 10 as the arch-shaped resilient arms 21 of the first preferred embodiment, and similarly, the extension blocks 30 are located at the same height as the occlusal surface 12 of the highest height position of the orthodontic arch 10 at one end away from the resilient arms 20, and the correction blocks 40 are located at the occlusal surface 12 of the highest height position of the orthodontic arch 10 and are in contact with the occlusal surface 12 of the highest height position, wherein, when the mouthpiece 1 is assembled in the orthodontic arch 10, the straightening profile 22 of the bow-shaped elastic arm 21 contacts the outer side surface of the straightening dental arch 10, and because the straightening profile 22 is smaller than the outer side profile of the straightening dental arch 10, the bow-shaped elastic arm 21 is pushed and expanded by the straightening dental arch 10 to expand the deformation, and each elastic arm 20 is deformed with the joint between every two elastic arms 20 as a pivot to form an elastic force P2 approximately parallel to the occlusal surface 12 to straighten the straightening dental arch 10.
However, the elastic force P2 generated by the resilient arms 20 being pushed against the orthodontic arch 10 is only for convenience of illustration, that is, as shown in fig. 2C, the orthodontic contour 22 forms the outer surface of the resilient arms 21, and the orthodontic contour 22 is larger than the inner contour of the orthodontic arch 10, so that when the dental mouthpiece 1 is assembled to the orthodontic arch 10, the orthodontic contour 22 of the resilient arms 21 contacts the inner surface of the orthodontic arch 10, the resilient arms 21 are positioned on the lingual side of the orthodontic arch 10, and the resilient arms 20 are pushed against the orthodontic arch 10 to be deformed to form the elastic force P2.
Furthermore, the opposing arch 50 is engaged with the orthodontic arch 10 as shown in fig. 2D such that a portion of teeth (e.g., molars) of the opposing arch 50 contact the orthodontic plane 42 of the orthodontic block 40 to generate the orthodontic force P1 while the remaining teeth (e.g., incisors and canines) of the opposing arch 50 do not contact the orthodontic arch 10, whereby, in this embodiment, the orthodontic arch 10 is simultaneously straightened by the orthodontic force P1 and the elastic force P2 when the orthodontic arch 10 and the opposing arch 50 are engaged with each other, thereby shortening the orthodontic time and improving efficiency.

As shown in the drawings, in this embodiment, when the mouthpiece 1 is installed in the orthodontic arch 10, all of the elastic arms 20 do not exceed the occlusal surface 12 of the lowest height position in the orthodontic arch 10, and the orthodontic block 40 still exceeds the occlusal surface 12 of the highest height position in the orthodontic arch 10, at which time, both the elastic arms 20 are positioned on the lingual side of the orthodontic arch 10 such that both the elastic arms 20 cover a part of the surface of the lingual side of the orthodontic arch 10, so that a part of the surface of the lingual side of the orthodontic arch 10 is exposed, and the contact surface 41 of the orthodontic block 40 contacts the incisors of the orthodontic arch 10, however, in this embodiment, the elastic arms 20 can be positioned on the buccal side of the orthodontic arch 10 in addition to the lingual side of the orthodontic arch 10, and the orthodontic profile 22 can be the same as the inner or outer profile of the orthodontic arch 10 as in the first preferred embodiment, or can be larger than the inner profile of the orthodontic arch 10 or smaller than the outer profile of the orthodontic arch 10 as in the second preferred embodiment, wherein, as shown in fig. 3D, when the orthodontic profile 22 is larger or smaller than the orthodontic arch 10, the elastic arm 20 can be deformed to form the elastic force P2 with the extension block 30 as a fulcrum.
As shown in FIG. 3C, when the dental arch 50 and the orthodontic arch 10 are engaged with each other, a part of teeth (e.g., incisors) of the dental arch 50 is brought into contact with the orthodontic block 40 to generate orthodontic force P1, and the incisors of the orthodontic arch 10 are straightened by the orthodontic force P1 to change the height position, so that the occlusal surfaces 12 of the incisors of the orthodontic arch 10 can be almost aligned with the occlusal surfaces 12 of the other teeth 11 (e.g., canine teeth and molar teeth) of the orthodontic arch 10.
