Mandible displacement adjustment device
View Patent ↗A mandible displacement adjusting device includes an upper braces and a lower braces, wherein the upper braces and the lower braces have an upper teeth accommodation space and a lower teeth accommodation space, the upper teeth accommodation space and the lower teeth accommodation space are made based on the tooth shape, and fits on the upper and lower dental arches of the human body respectively, and the side walls of the upper braces and lower braces extend out a first positioning part and a second positioning part corresponding to the upper molar area and the lower molar area. When the user wear the upper braces and the lower braces, the first positioning part and the second positioning part would be driven to fit together, and maintain a movable displacement space, so that when the mandible of the human body is moved forward and fixed, it will not cause the mandible of the human body due to tightening, neither cause the discomfort at the condyle, while avoiding the back of the tongue slumping down and blocking the breathing passage.
1 . A mandible displacement adjustment device, comprising:
an upper braces, having an upper teeth accommodation space formed according to a shape of teeth to fit on a maxilla of a human body, wherein on a side wall of the upper braces extends a first positioning part configured to correspond to an upper molar area, the first positioning part having a first extension part extending from a buccal surface of the side wall of the upper braces and configured to extend obliquely at 35-55 degrees toward a lower molar area, and a front end of the first extension part configured to face a front teeth area bending to form a first hook;
a lower braces, having a lower teeth accommodation space formed according to the shape of the teeth to fit on a mandibular dental arch of the human body, wherein on a side wall of the lower braces extends out a second positioning part configured to correspond to a lower molar area, the second positioning part having a second extension part extending from a buccal surface of the side wall of the lower braces and configured to extend obliquely at 35-55 degrees toward the upper molar area, and a front end of the second extension part is configured to face a condyle of the mandible to form a second hook;
wherein the first positioning part and the second positioning part extending from the buccal surfaces of the upper braces and the lower braces, respectively, allow the upper braces and the lower braces to meet and contact each other;
wherein the first positioning part and the second positioning part are a C-shaped structure that can be movably engaged;
wherein after the upper braces and the lower braces are worn, the first hook is driven to engage with the second hook to form an X-shaped crossing, so that the mandible of the human body is configured to be moved forward and positioned, and the 35-55 degree extension of the first and second extension parts creates an omnidirectional activity space for the second extension part and the second hook moving freely in the omnidirectional activity space between the engaged first hook and second hook, configured to let the mandible move freely to avoid discomfort due to wearing at a condyle of the mandible for a long time;
wherein the second extension part of the second positioning part is blocked by the first extension part of the first positioning part and is unable to move backward at a blocking position when moving backward in a horizontal direction, and the blocking position is a preset position for mandible forward positioning,
when a mouth of the human body is closed, the first hook of the first positioning part and the second hook of the second positioning part are configured to engage with each other, and when the mandible moves downward, the second hook is configured to be blocked by the first hook to keep the mouth of the human body closed.
2 . The mandible displacement adjustment device of claim 1 , wherein both the upper molar area and the lower molar area each are configured to include a first premolar, a second premolar, a first molar, a second molar, and include a first premolar, a second premolar, a first molar, a second molar, and positions of the first positioning part and the second positioning part are configured to correspond to one side of either of the second molar and the first molar, or between any two molars.
3 . The mandible displacement adjustment device of claim 2 , wherein a preferred position of the first positioning part and the second positioning part correspond to a side of the first molar.
4 . The mandible displacement adjustment device of claim 3 , wherein the first positioning part is positioned on the position of the upper molar area, which is a preset position of mandible forward positioning, the position of the first positioning part configured to be located in the upper molar area is tailored according to an acceptable position of the mandible forward positioning, so that the mandible will not generate discomfort when the mandible is positioned forward.
5 . The mandible displacement adjustment device of claim 1 , wherein the upper braces or/and the lower braces are provided with an opening corresponding to a front teeth area of a human maxillary dental arch or/and the mandibular dental arch of the human body, so as to expose a tooth surface of the front teeth area.
6 . The mandible displacement adjustment device of claim 1 , wherein a thickness of the upper braces and the lower braces corresponding to a front teeth area of a human maxillary dental arch and the mandibular dental arch of the human body is less than 1 mm.
7 . The mandible displacement adjustment device of claim 1 , wherein the first extension part of the first positioning part or the second extension part of the second positioning part is set with an adjuster, a thickness of the adjuster is used to finely adjust a position of the mandible forward positioning.
