Description

The utility model relates to medicine and can be used if it is necessary to reduce excess weight in a person.

Known devices are designed to correct weight and reduce the oral cavity by reducing the volume of the oral cavity, and, consequently, reduce the amount of food intake and reduce calories consumed.

These include methods of weight loss using elastic devices that are attached to the mouth to limit food intake (US patent No. 4825881, publ. 1989 and No. 4883072, publ. 1989).

Known solution, aimed at reducing chewing activity, thereby reducing food intake using a device installed next to one or more teeth. The device includes a metal frame having a curved front and opposite blades extended in a rearward direction with the first and second elements of the wing mounted on it (US patent No. 4727867, publ. 1986).

A device for limiting the opening of the mouth is known, containing fixing elements, which are made in the form of metal orthodontic crowns on the first molars of the upper and lower jaws. To the vestibular surface of the fixing elements are soldered elements for fastening the motion limiter. Fastening elements are made in the form of steel wire loops and are bent in the form of locks for snapping the motion limiter in the direction of the transitional fold. The motion limiter has the form of a ring made of an elastic material reinforced with a metal cable (RF patent No. 2212207, IPC A61C 7/36, A61F 5/00, publ. 20.09.2003).

Known intraoral device installed for weight loss and control (Oral appliance and method for use in weight loss and control), designed to slow down the process of absorption of food and, thereby, accelerate the onset of satiety. To this end, a device consisting of lower and upper parts is fixed on the upper and lower teeth, and both parts are connected by a flexible element. The device includes a bracket and a plastic latch, or a fastener element with a buckle for fixing, or a bracket with a fixing button. Associated brackets include pins or bolts for a fixed insertion through a selected one of the holes (US patent No. 2003/075186, published 04/24/2003).

However, when using this method and device, the teeth are subjected to mechanical stress, which leads to their destruction, and also there are forces aimed at extraction (pulling out) of the tooth.

An intraoral fixation device between the upper and lower jaws is known, which completely excludes the possibility of chewing food, and the connection and alignment of the intraoral device relative to each other is carried out using a power wire and intermaxillary fixation elements, and the power wire is attached to the intraoral device through holes made directly in intraoral device or fasteners attached to it, made in the form of plastic or metal tubes. At the same time, a metallized thread and/or a wire lock made in the form of a U-shaped wire clip are used as elements of intermaxillary fixation (RF patent No. 2554332, IPC A61M 21/00, publ. 06/27/2015)

The disadvantage of these solutions is the bulkiness of the devices used, their lack of aesthetics, the complexity of installation, removal and use. In addition, these methods and devices do not allow the user to maintain a normal quality of life, as they interfere with speech activity, create constant discomfort by irritating the oral mucosa, and affect teeth and soft tissues.

The objective of the claimed utility model is to create an intraoral device that does not traumatize the teeth and soft tissues to limit the movement of the jaw to reduce excess weight, eliminating discomfort during use and allowing to achieve results while maintaining the user's normal quality of life.

The technical result is to reduce injury to teeth and soft tissues.

The technical result is achieved by the fact that the claimed intraoral device for limiting the movement of the jaw to reduce excess weight, performing passive fixation between the upper and lower jaws, is characterized by the presence of two longitudinal parts, for placement on the upper and lower jaw on the outside of at least two teeth, moreover, the parts are interconnected by flexible elements that limit the amount of opening of the jaw.

The utility model is illustrated by drawings.

Fig. 1 is a general view of the intraoral device.

Fig. 2 - placement of the intraoral device on the teeth.

Fig. 3 - placement of flexible elements when closing the jaws.

Fig. 4 - use of the intraoral device according to example 1.

The inventive intraoral device consists of 1 - longitudinal part; 2 - flexible element.

The intraoral device is made of plastic used in dentistry and is used as follows.

The longitudinal part 1 is installed on the upper and lower jaws using adhesive materials used in dentistry. The choice of teeth for installation is determined by the specialist during a preliminary examination. Flexible elements 2 fix the movement of the lower jaw and limit the width of the opening of the mouth. Thus, they slow down the process of chewing, reduce the amount of food consumed, while maintaining the possibility of speech activity. After installing the intraoral device, the patient is selected an individual weight correction program, including a diet that includes a diet with low-calorie liquid food and a set of physical exercises.

The inventive design of the intraoral device allows the longitudinal parts and the teeth to which they are attached to equally distribute the load of holding the jaw, thereby minimizing the risk of displacement or extraction of teeth. Flexible elements do not interfere with the closing of the jaws and at the same time do not cause discomfort in the oral cavity. The presence of the proposed device in the oral cavity does not affect the quality of speech, does not interfere with sleep and is not noticeable to others.

Implementation examples.

Example 1

Patient Zh. weighed 128 kg. According to the results of the survey, it was determined that the overweight was 35 kg. There are no health contraindications for the use of an intraoral device. Determined the course of weight loss by developing an individual diet with low-calorie liquid food. The dentist installed the intraoral device using a resin adhesive material as shown in FIG. 4. Patient Zh. ate liquid low-calorie food through a tube. After 2 weeks, the weight loss was 20 kg. After removal of the intraoral device, an individual set of exercises and diet were selected. After 10 days, the course was repeated with the installation of an intraoral device also for 2 weeks. As a result, the weight of patient J. reached 95 kg. The total weight loss was 33 kg. During the entire period of using the intraoral device, patient Zh. did not experience any discomfort and led a normal life.

Example 2

Patient M. weighed 140 kg. According to the results of the survey, it was determined that the overweight was 50 kg. There are no health contraindications for the use of an intraoral device. Determined the course of weight loss by developing an individual diet with low-calorie liquid food. The dentist installed an intraoral device using a polymer adhesive material. Patient M. ate liquid low-calorie food through a tube. After 6 weeks, the weight loss was 40 kg. After removal of the intraoral device, an individual set of exercises and diet were selected. After 10 days, the course was repeated with the installation of an intraoral device for 2 weeks. The patient's weight reached the result - 89 kg. The total weight loss was 51 kg. During the entire period of using the intraoral device, patient M. did not experience any discomfort and led a normal life.

Thus, the use of the proposed intraoral device ensures the complete exclusion of opening the mouth and chewing movements and, consequently, the penetration of any solid food, except for liquid, as a result of which the intake of calories into the body is limited, which helps to gradually reduce the patient's food dependence and exclude an increase in the caloric content of the food taken. In this case, an intraoral biologically safe device is used, which does not have a violent effect on the dentition, but completely prevents the chewing movement of the jaws and the chewing of solid food.
