Description

Mandibular advancement holder for treating sleep apnea

Technical Field

The invention relates to a mandibular advancement holder for the treatment of sleep apnea.

Background

There are various snoring reasons during sleeping, and the main snoring reason is respiratory tract and throat cavity, when the respiratory channel is narrowed because the soft jaw, tongue root and other throat soft tissue parts sink and sink due to gravity (obesity, relaxation), the sucked air must force to pass through the narrow place, at this time, the resistance of the air is naturally increased, and the mucosa or secretion of the narrowed part of the respiratory channel will vibrate or generate friction sound, and the vibration sound and friction sound are snoring.

The medical field solves the snoring problem during sleeping by moving the lower jaw forwards to make the upper jaw and the lower jaw dislocated, which is known as the most effective method. The existing snore stopping tooth socket aims to solve the problem of snoring fundamentally, but has a plurality of defects and is easy to fall off; the upper and lower tooth sockets are only used for enabling the upper and lower teeth to be occluded and then opening the mouth, so that the lower jaw is prevented from being retracted, the soft jaw, the tongue root and other throat soft tissue parts are prevented from sinking to a breathing channel, the upper and lower jaws are not staggered, the snore stopping effect is not ideal, and the tooth sockets are easy to fall off when yawning is performed in the sleeping process; some structural parts and connecting parts are unreasonable in design, such as sharp edges and corners, complex clamping locking part matching and being located at sensitive tongue tips, easy extrusion injury, tongue tip injury or oral cavity injury, and the like, and moreover, foreign body sensation in the mouth cannot be eliminated, so that the sleeping is uncomfortable and influenced.

Through patent search, there are the following known prior art solutions: chinese patents CN 107773343 and CN 108542584.

Detailed Description

The invention is further illustrated by the following figures and examples.

In the present invention, as shown in fig. 1 and 2: the upper shell 10 and the lower shell 20 are a pair and are used together. A pair of tooth sockets are different from other articles and can only be manufactured in a personalized way, for example, the tooth sockets are manufactured by adopting a traditional dental film method which is mature in hospitals and teeth. Still another is the more advanced use of "3D" printing techniques to print a pair of braces for each patient.

The embodiment example is shown in figure 1: a mandibular advancement holder for treating sleep apnea comprises an upper tooth socket 10 in a U-shaped half-closed shape and a lower tooth socket 20 in an approximately symmetrical shape, wherein a lower concave block 11 is arranged at the lower part of an upper front inner wall 14 of the upper tooth socket 10, an upper convex block 21 is arranged at the upper part of a lower front inner wall 23 of the lower tooth socket 20, and a convex structural part of the lower concave block 11 clamps a concave structure of the upper convex block 21 for locking, which is a general scheme.

In the present invention, example 1 is included: the front end of the bolt 223 of the bolt assembly 22 is matched with the concave pit 13 on the front outer side of the lower convex block 11, the lower end of the lower convex block 11 is in a forward tilting state and forms an included angle of 50 degrees to 80 degrees with the horizontal plane, and as shown in fig. 6, the upper tooth socket 10 and the lower tooth socket 20 are locked on the front portion. The built-in nut 222 of the bolt assembly 22 is built in the middle upper part of the upper projection 21, and the bolt 223 is adjusted to move back and forth by the bidirectional rotation of the bolt handle 224. The adjusting distance of the bolt 223 is 1mm-10 mm. The structure is shown in fig. 3, 4 and 7.

Also included is embodiment 2: the convex edge 211 on the upper part of the upper bump 21 is matched with the concave groove 12 on the lower bump 11 in a clamping way, so that the upper tooth socket 10 and the lower tooth socket 20 can be locked at the front part, the convex edge 211 is arranged on the inner side of the top end of the bump 21, and the width and the height of the convex edge 211 are both smaller than the corresponding width and the height of the concave groove 12. The locked state is shown in fig. 5.

In addition, the scheme shown in embodiment 2 is also suitable for maintaining the early correction result after the correction stage shown in embodiment 1 is finished, and the lower jaw does not need to be stretched in a large range any more at this stage, and is replaced by the lower dental mouthpiece 20 shown in fig. 5, so that the comfort is better, and after the longer metal bolt assembly 22 is not arranged on the lower dental mouthpiece 20, the foreign body sensation in the oral cavity is eliminated, the wearing comfort is optimal, and the sleep is not influenced.

The use process is as follows: firstly, the customized upper dental mouthpiece 10 is worn outside the upper teeth, then the lower dental mouthpiece 20 with the bolt component 22 is worn outside the lower teeth, the patient moves the lower jaw forwards, after the front end of the bolt 223 enters the pit 13 to be clamped, the bolt handle 224 is rotated in the forward direction to continue stretching the lower jaw, the lower dental mouthpiece is not easy to be excessively stretched until the lower dental mouthpiece is properly used for the first time, the sense of foreign body in the oral cavity is not uncomfortable, the snoring symptom is lightened or disappears after a period of use, and at the moment, the lower dental mouthpiece is changed into the lower dental mouthpiece 20 without the bolt component 22 as shown in fig. 5, and the lower dental mouthpiece can not be stretched to adapt and obviously has the sense of foreign body, and can also be used alternately.
