Description

Technical Field

[0001] The utility model relates to the technical field of muscle activators, in particular to a muscle activator for preventing tooth torsion. Background Art

[0002] Myo-actuator: Myo-actuator is the most common type. The appliance consists of a plastic base, without a retaining clasp or a force-generating device. The maxillary part of the base covers the entire palate, and the mandibular part extends downward to the floor of the mouth. The distal end of the base reaches the distal end of the first permanent molar. The upper and lower bases are connected to form a plastic cap for the lower incisor in the anterior area to press the lower incisor, which prevents the lower incisor from erupting vertically and tilting labially. A hyperbolic lip bow is attached between the maxillary canines, which can transmit the corrective force of the muscles to the upper anterior teeth. If the base on the palatal side of the upper anterior teeth, including the alveolar part, is adjusted and buffered, the upper anterior teeth will tilt toward the palate under the influence of the lip bow. The head cap extraoral bow myo-actuator: It is a modified myo-actuator composed of an extraoral traction device and a myo-actuator. It is widely used in the correction of maxillary protrusion and mandibular retraction. It mainly achieves the correction effect by inhibiting the growth of the maxilla and stimulating the growth of the mandible.

[0003] During the treatment with the muscle activator, teeth may become irregular, resulting in the twisting of the upper teeth. However, most existing muscle activators do not have the function of preventing tooth twisting, so tooth twisting occurs from time to time.

[0004] Therefore, a muscle activator for preventing tooth torsion is proposed. Utility Model Content

[0014] Beneficial effects of the utility model:

[0015] The utility model generates force when biting by setting a resin base so that the top protruding part thereof is forced to push the groove mark to generate thrust on the lower front teeth, thereby moving the lower jaw as a whole forward and improving the retraction of the lower jaw. The first rotating spring is set so that the extraoral traction device can buffer the force when generating traction force, thereby reducing the force burden on the teeth.

Since the U-shaped cross bar 2 itself has elasticity, the reaction generated by it The resin base 1 is pushed close to the upper molars under the force, thereby completing the retention. The resin base 1 also includes a groove impression 8 arranged at the bottom end of the resin base 1, and the groove impression 8 is adapted to the lower front teeth. The lower front teeth are placed in the groove impression 8 and are tightly attached to it.

At this time, the upper front teeth are subjected to the pressure of the extraoral bow 3, thereby inhibiting the protrusion of the upper front teeth. At the same time, the extraoral bow 3 is subjected to the traction force, so that the first rotation spring 5 is subjected to the pressure to generate a reaction force, thereby having a buffering effect on the traction force, thereby reducing the force burden on the upper front teeth.
