Description

Mandatory distance measuring instrument

The present invention relates to a mandibular movement distance measuring instrument, and more particularly, to a mandibular movement distance measuring instrument capable of measuring the maneuvering distance of the mandible in order to easily and quickly produce a snoring mechanism.

Typically, snoring occurs when the throat is narrowed through which the air passes before it enters the airways while we breathe, making it difficult for air to enter and exit. This snoring is a symptom that helps people to know that they have difficulty breathing during sleep. When we breathe, the air passes through soft parts of the human body, such as the palate, neck, tonsils, tongue, etc. During the day, the surrounding muscles help keep these parts in place and block the air passages, making them almost no sound. However, during sleep, muscles relax and stretch, so the air passages are partially narrowed, causing the snoring to vibrate the soft tissues around them as the air passes through them.

On the other hand, the very severe form of snoring patients may temporarily block air passages due to severe muscle relaxation during sleep or severe obesity, and prevent air from flowing into the lungs at all. This is called obstructive sleep apnea.

If this condition persists, the lungs will not get fresh air, so the brain that senses it will wake up our body and contract the muscles to open the air passages again. It is only at this time that the patient breathes once more and resumes breathing. If this happens repeatedly every night, it can cause severe drowsiness and fatigue during the day, often causing traffic accidents. Prolonged abnormalities can also increase the burden on the heart and lungs, leading to serious complications such as hypertension, arrhythmia, and myocardial infarction.

In order to treat such sleep apnea, nasal surgery, pharyngeal laser surgery, snoring pillows, and mouth bites are used.

First, nasal surgery and pharyngeal laser surgery may improve temporary snoring, but the symptoms improved after surgery have a disadvantage that may worsen over time.

Snoring pillows have the advantage of not requiring surgery, but there are many disadvantages in that they do not function properly because they are often displaced from their original position during sleep.

The mouth biting device is a device that prevents snoring by pulling the lower jaw joint using a device sandwiched between the upper and lower teeth. Using this instrument, the jaw joints are pulled further apart between the soft palate and its associated neck, tongue root, and tonsils, making the air passages much wider. By this widened airway, the air sucked for breathing during sleep passes freely while avoiding parts such as the neck, tongue root, tonsils, etc., thereby preventing the soft palate and tonsil from vibrating due to the passage of air.

Such a mouth-to-sleep device does not require any surgery and has been widely used in recent years because it keeps the airway expanded while sleeping. Related to the device that sleeps in the mouth during sleep is the Republic of Korea Patent Publication No. 10-2006-0089860 which is a mouthpiece structure. Such a mouthpiece-type structure is inconvenient to move the jaw joint during sleep, there is a registered patent 787188 has been filed and registered by the present applicant to solve this problem.

As shown in FIG. 1, the technique disclosed in Patent Registration No. 787188 includes an upper support 10 supported by the upper teeth 50, an upper locking jaw 20 protruding downward with respect to the upper support 10. The lower support 30 which is supported by the lower teeth 60 and the lower support projection 40 which protrudes upward with respect to the lower support 30 may be caught by the upper locking jaw 20. On the other hand, the upper locking jaw 20 is composed of a lower extension portion 21 and the departure prevention portion 22 extending forward from the lower extension portion 21, the lower locking jaw 40 is the upper extension portion 41 ) And a departure prevention part 42 extending rearward from the upper extension part 41.

This snoring prevention mechanism has the advantage that it is possible to freely move the jaw joint in a predetermined range during sleep to maintain a more comfortable sleep state.

Such snoring mechanism can be manufactured as follows.

First, a plaster model for the maxilla and mandible of the patient is produced. Thereafter, the upper support and the lower support are manufactured in a predetermined form. After that, after considering the characteristics of the patient to find out the dimensions that can be optimally pulled out the mandible, implement the dimensions on the plaster model. Thereafter, the upper support and the lower support are sandwiched on the upper and lower gypsum models, and the upper catching jaw and the lower catching jaw are adhered to the upper support and the upper support to finish the work.

The most difficult problem in the manufacturing process is to determine the optimal mandibular position by measuring the optimal mandibular movement distance according to the characteristics of the patient. To do this, first calculate the movement distance of the mandible which the patient can subtract out to the maximum. Afterwards, the patient finds the most comfortable location within the distance to minimize snoring. After that, the position will be embodied on the stone model.

However, in the related art, there is a movement distance measuring instrument for selecting a position where the mandible can move forward while the user almost closes his mouth, since it is necessary to measure the distance from which the mandible can be pulled out. Inaccurate. In other words, the condition for inserting the snoring prevention mechanism is to remove the mandible while the mouth is open to a certain degree, it is not desirable to measure the distance from which the mandible is removed in the state of closing the mouth. The reason for this is that the distance that the patient can remove the mandible with the mouth closed and the distance with which the mandible can be removed with the mouth open to some extent are different.

In addition, after measuring the maximum movement distance, a predetermined value within the maximum movement distance is set as the initial position of the mandible, and the plaster model must be manufactured using the initial position of the mandible, which is not easy. In other words, it is not easy to select a position to pull the mandible forward several centimeters forward in the open state rather than the closed state.
