Technical Field

The invention belongs to the field of medical appliances, and relates to an orthodontic device, in particular to an attached double-guide-plate invisible appliance for treating mandibular retropulsion.

Background

In modern oral orthodontic clinical treatment, orthodontics mainly depends on wearing an appliance inside or outside an oral cavity to apply proper 'biological materials' to teeth, alveolar bones and jawbones so as to generate physiological movement and achieve the aim of orthodontics. Generally speaking, mandibular retraction is often combined with deep draping.

At present, orthodontics treatment mandibular retraction mainly adopts appliances: double-pad orthosis, transparent orthosis. Each of these appliances has disadvantages:

1. the double-pad appliance (Twin-Block appliance) belongs to a functional appliance, stimulates the growth of mandible by functionally advancing the mandible, has good effect of treating mandible retraction, and is widely applied clinically. But the moving amount of the mandibular advancement is not easy to control, the mandibular advancement can be ensured to be in place only by adjusting for a plurality of times, moreover, the closing pad can press down the posterior teeth in the treatment process, after the functional mandibular advancement is completed, the upper jaw closing pad needs to be grinded down by times through 4-6 times of re-diagnosis until the upper jaw closing pad is completely grinded off, the mandibular molars are promoted to erupt vertically until the upper and lower molars establish the occlusion relation, and then the lower jaw closing pad is grinded off for 2-3 times to establish the occlusion relation in the bicuspid area. The number of times of the return visits is more, the clinical operation is more complicated, the treatment course is longer, and the posterior teeth move back and forth after being pressed down and then stretched.

2. In recent years, the transparent appliance applies the correction force by means of various accessories, the effect is better and better, and the application is wider and wider. At present, the most imported transparent appliance used in China is a transparent appliance from America which is suitable for the United states, and the most domestic transparent appliance used in China is an age-angel transparent appliance. The hidden beautiful transparent appliance for treating mandibular retroversion has buccal double-precision wing supports, and the age-made transparent appliance for treating mandibular retroversion has hidden function for correcting TB (twin-block) technology. The action mechanism of the two is similar to that of a twin-pad appliance (twin-block), but the two has the defects that the posterior teeth can be pressed down in the treatment process, the posterior teeth need to be corrected after the lower jaw is moved forwards functionally, the upper and lower molars and the bicuspids are long and establish an occlusion relation, the posterior teeth move back and forth after being pressed down and then stretched, and the treatment course is prolonged. Secondly, the treatment effect of deep combination is slow. The hidden beautiful transparent appliance is deeply covered with a Bite guide plate technology, and the transparent appliance is naturally deeply covered with a Bite guide plate accessory in times, but the defects that the Bite guide plate and the Bite guide plate accessory are both a small part of the original tooth socket, the front and back diameters are within 3 mm, the front teeth of the lower jaw of some people are easy to Bite behind the Bite guide plate and the Bite guide plate accessory, the front teeth are not bitten on the guide plate, the elastic force of the transparent appliance material is small, and the transparent appliance has poor effect of elastic treatment of the deep covering. Normally, the anterior teeth are normally closed by about 2 mm in a designed 'over-correction' manner, but the aim is not accurately achieved by the over-correction design, the tooth socket is not attached easily, and the treatment course is prolonged.

Disclosure of Invention

The invention aims to provide an invisible appliance with double guide plates, aiming at the defects of the prior art, the invisible appliance adopts the design of the double guide plates and combines a front guide projection and a front guide groove, so that posterior teeth cannot be depressed when a lower jaw is guided to move forwards, the back teeth are prevented from moving back and forth after being depressed and elongated, the treatment course is shortened, an anterior tooth area can be used for replacing the posterior teeth to chew food in the treatment process, the anterior teeth of the upper jaw and the lower jaw can be depressed, the length of the posterior teeth is also facilitated, and the invisible appliance has a good effect on the treatment of deep occlusion when the lower jaw is guided to move forwards.

The technical scheme adopted by the invention is as follows:

the invisible appliance with the double guide plates comprises transparent tooth sockets, wherein each tooth socket comprises an upper jaw tooth socket and a lower jaw tooth socket, an upper jaw guide plate is arranged on the tongue side of a front tooth area of the upper jaw tooth socket, a lower jaw guide plate is arranged on the tongue side of the front tooth area of the lower jaw tooth socket, a front guide protrusion is arranged on the upper jaw guide plate, a front guide groove matched with the front guide protrusion is arranged on the lower jaw guide plate, and the upper jaw tooth socket and the lower jaw tooth socket are basically aligned when the front guide protrusion is guided into the front guide groove. The upper jaw dental socket and the lower jaw dental socket are sleeved on the upper jaw and the lower jaw, when the front guide protrusion of the upper jaw guide plate does not enter the front guide groove of the lower jaw guide plate, the upper jaw and the lower jaw cannot be occluded together due to interference of the front guide protrusion, only the lower jaw extends forwards until the front guide protrusion enters the front guide groove, so that the upper jaw guide plate and the lower jaw guide plate in the front dental area are occluded together, the upper jaw and the lower jaw can be occluded together, the upper jaw and the lower jaw are aligned, and the purpose of treating the lower jaw retraction is achieved. The lower teeth can not be pressed down in the guiding process, the extension of the lower teeth is facilitated, the upper and lower mandible anterior teeth can be pressed down, and the lower mandible retraction and deep draping can be treated. The guide plate is arranged on the tongue side of the tooth socket, and the front surface of the guide plate cannot be seen, so that the invisible effect is achieved.

As a further improvement of the invention, the longitudinal sections of the upper jaw guide plate and the lower jaw guide plate are triangular-like, the bottom surface of the upper jaw guide plate is downward and horizontally arranged, and the bottom surface of the lower jaw guide plate is upward and horizontally arranged, so that the anterior tooth area of a patient has a wider occlusion area, and the patient can chew food instead of posterior teeth, and simultaneously, the effects of mutual 'propping' of the upper and lower anterior teeth, auxiliary chewing, pressure increasing and deep covering treatment are achieved. Preferably, the bottom surfaces (chewing surfaces) of the upper jaw guide plate and the lower jaw guide plate are designed into gear-shaped structures, and the gear-shaped structures simulate uneven tooth surfaces of posterior teeth, so that the gear-shaped structures are beneficial to grinding food and improving the chewing effect.

As a further improvement of the invention, the leading protrusion is designed to be of an inverted conical structure, and correspondingly, the leading groove is designed to be of an inverted conical structure.

The invention has simple structure and convenient use, adopts the design of double guide plates combined with the front guide projection and the front guide groove, can not press down the posterior teeth when guiding the lower jaw to extend forwards, avoids the problem that the posterior teeth press down first and then extend to and fro when the conventional appliance treats the mandibular retrosystole, shortens the treatment course, can also use the anterior teeth area to replace the posterior teeth to chew food in the treatment process, not only presses down the upper and lower anterior teeth, but also is beneficial to the posterior teeth length, has good effect on the treatment of deep synechia, and achieves the effect of treating the mandibular retrosystole and deep synechia simultaneously.

Detailed Description

The invention will now be further described, by way of example only, and not by way of limitation, with reference to the accompanying drawings.

In the structures shown in fig. 1, 2 and 3, the invisible appliance with the double guide plates comprises transparent tooth sockets, wherein the tooth sockets comprise an upper jaw tooth socket 1 and a lower jaw tooth socket 2, are made of elastic transparent high polymer materials (such as transparent biological ceramic materials), and are made of special transparent high polymer materials, so that the appearance is attractive, the biocompatibility is better, the friction force is small when the appliance is worn, and the feeling is more comfortable. An upper jaw guide plate 4 with a triangle-like longitudinal section is arranged on the lingual side of the anterior dental area of an upper jaw dental mouthpiece 1, the bottom surface (upper chewable surface 4-1) of the upper jaw guide plate 4 is arranged downwards and horizontally, a lower jaw guide plate 3 with a triangle-like longitudinal section is arranged on the lingual side of the anterior dental area of a lower jaw dental mouthpiece 2, and the bottom surface (lower chewable surface 3-1) of the lower jaw guide plate 3 is arranged upwards and horizontally, so that the anterior dental area of a patient has a wider occlusal area and can replace the chewing of the posterior teeth to chew food, and the upper chewable surface 4-1 and the lower chewable surface 3-1 are both designed into a gear-shaped structure, thereby being beneficial to grinding food and improving the chewing effect; the upper jaw guide plate 4 is provided with an inverted conical front guide projection 4-2, the lower jaw guide plate 3 is provided with an inverted conical front guide groove 3-2 matched with the front guide projection, and when the front guide projection is guided into the front guide groove, the front tooth areas of the upper jaw dental mouthpiece and the lower jaw dental mouthpiece are basically aligned.

According to the design concept of the invention, as long as the mandible is ensured to extend forwards and not retract backwards, the mandible can move forwards and backwards, but can not move backwards. Because the rear part of the lower jaw guide plate 3 can form a step with the tooth socket, the front guide protrusion can be directly clamped, and the lower jaw cannot retreat, so that the rear part of the lower jaw guide plate 3 can be used as a deformed front guide groove as long as the design is reasonable and the size is determined, and the effect of the application is realized.

In the practice of the invention, a set of multiple mandibular braces 2 may be used to index the mandible in steps by changing the position of the leading channel 3-2 on the mandibular guide 3. After being in place, the mandible remains substantially stable in the protracted position for about 1-2 months.

The working principle of the invention is as follows:

when the mandible is treated, the upper jaw dental mouthpiece 1 and the lower jaw dental mouthpiece 2 are respectively sleeved (worn) on the upper jaw and the lower jaw of a patient, and the upper jaw and the lower jaw are not occluded together due to interference of the front guide projection 4-2. The lower jaw is extended forwards, the front guide projection 4-2 of the upper jaw guide plate 4 enters the front guide groove 3-2 of the lower jaw guide plate 3, the upper jaw and the lower jaw can be occluded together, and the lower jaw can not be retracted because the front guide projection 4-2 is clamped in the front guide groove 3-2, so that the lower jaw can be treated by retracting the lower jaw under the condition that the normal growth of the rear teeth is not influenced. Since the upper jaw guide 4 has an upper chewing surface 4-1 and the lower jaw guide 3 has a lower chewing surface 3-1, the anterior dental area of the patient can chew food instead of the posterior teeth during treatment, and the pressure between the upper and lower jaws can be increased to treat deep occlusions.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
