Description

Invisible appliance

Technical Field

The utility model relates to an oral medicine technical field especially relates to a ware is rescued in stealthy.

Background

The bracket-free invisible correction provides an attractive and comfortable correction method for patients, but the invisible correction only wraps the dental crown part, so that the control on the dental crown is weak. Particularly, for the tooth extraction cases needing adduction of anterior teeth, the 'arch' effect of inward inclination and elongation of anterior teeth and mesial inclination of posterior teeth in invisible correction is more remarkable. The existing method is to implant 1-2 micro-implant nails at the anterior labial side of the anterior teeth, implant 1 micro-implant nail at each of the buccal sides of the left and right posterior teeth, and realize the indentation of the anterior teeth, the tooth root and tongue torque movement and the anchorage control of the posterior teeth through the traction of an elastic rubber ring between the implant nails and an invisible orthodontic appliance. The planting nail and the traction ring are arranged on the labial and buccal sides, so that the beauty is obviously influenced; in addition, the micro-implant nail on the buccal side has higher shedding rate, and the space of the labial and buccal sulcus is limited, so that the placement position of the implant nail is limited, and the effect is further influenced.

The control of the upper anterior teeth in the tooth extraction correction is a treatment difficulty of the invisible correction technology, and inward contraction of the anterior tongues easily causes inclination and extension of the upper anterior tongues, forward inclination of the posterior teeth, early contact of the anterior teeth and opening and closing of the posterior teeth, so that a so-called arch effect is generated. The "doming effect" is more likely to occur because the invisible appliances are softer than the fixed appliances.
