Invisible appliance with double guide plates

Technical Field

The utility model belongs to the field of medical equipment, relates to an orthodontic device, in particular to an attached double-guide plate invisible appliance for treating mandibular retrogradation.

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 technology of 'Bite ramp' for treating the deep coverage of the invisible beauty transparent appliance is adopted, and the 'Bite ramp accessory' for treating the deep coverage of the invisible beauty transparent appliance is naturally adopted in times, but the defects that the 'Bite ramp' and the 'Bite ramp accessory' both use a small part of the original tooth socket to protrude, 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 ramp' and the 'Bite ramp accessory' and are not bitten on the ramp, the elastic force of the transparent appliance material is small, and the elastic treatment deep coverage effect of the transparent appliance is poor. 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.
