说明书全文 | This non-provisional patent application claims priority to the provisional patent application having Ser. No. 62/122,105, filed on Oct. 10, 2014. This disclosure generally relates to orthodontic devices for assisting in orthodontic treatments or procedures, and more particularly to a dental repositioning device for repositioning a tooth for use in orthodontic correction treatments or procedures. Orthodontists treat patients by controlling the movement and displacement of teeth or the jaws in a mouth by use of various orthodontic devices and procedures. Movement or rotation of a tooth within the mouth may be accomplished through the use of external forces applied to the tooth. To ensure that the moved or treated tooth remains in a desired location in the jaw bone, an external force is applied to the tooth for an extended period of time. Once the tooth has reached a desired position or orientation, the force may be removed. Some examples of devices used to apply the necessary force to the tooth are braces, brackets, buccal tubes, wires, clamps, or rubber bands. One known orthodontic device that has been used to correct the misalignment of teeth is an intra-oral device. The intra-oral device may include various components such as telescoping mechanisms, pins, rods, Herbst appliances, elastic materials, and chains. These devices can be bulky, impede tongue mobility, are uncomfortable to wear, and interfere with good oral hygiene. The intra-oral device are typically positioned on the cuspids, bicuspids, or molars and away from a patient's anterior teeth. In view of this, the intra-oral device is hidden in the mouth of the patient. However, one problem associated with the use of the intra-oral device is that the device may break during use. If the device breaks, then the patient must return to the orthodontist to have the component or components replaced to continue the procedure or treatment. Further, during breakage of one or more of the components, damage or injury to the oral cavity may occur. For example, a wire may become dislodged and be inserted or impaled into the cheek. Various other devices have been proposed and used to attempt to correct the misalignment of teeth. For example, a force-applying device such as a headgear device that includes strapping that extends around the head of the patient and connects to various brackets attached to the teeth has been used. Since headgear is worn outside the mouth, it has been found unacceptable to some patients due to the physical visual obstruction and embarrassment of wearing it. Further, due to the embarrassment, some patients fail to wear the headgear device on a consistent basis. This can impact the progress of treatment and the length of time of treatment. If the time of treatment is extended, this could increase the cost of the treatment. The present disclosure is designed to obviate and overcome many of the disadvantages and shortcomings experienced with prior orthodontic devices. Moreover, the present disclosure is related to a dental repositioning device that can reposition teeth within a mouth of a patient to correct a misaligned condition. Further, it would be advantageous to have a dental repositioning device that can be easily adjusted or incrementally adjusted to correct a misaligned condition. The present disclosure is a dental repositioning device which comprises a support plate having a first rod embedded therein and a second rod embedded therein, a first anterior mechanism having a top opening for receiving a set screw and a rear opening, a second anterior mechanism having a top opening for receiving a set screw and a rear opening, a first rod connected between the first anterior mechanism and a first rear mechanism and a spring inserted over the first rod between the first anterior mechanism and the first rear mechanism, a second rod connected between the second anterior mechanism and a second rear mechanism and a spring inserted over the second rod between the second anterior mechanism and the second rear mechanism, a first Z-clip for insertion into the first rear mechanism and a first buccal tube, and a second Z-clip for insertion into the second rear mechanism and a second buccal tube. In another form of the present disclosure, a dental repositioning device comprises a support plate having a rod embedded therein with the rod having a pair of ends extending out of the support plate, a first anterior mechanism having a top opening for receiving a set screw, a front opening for receiving one of the pair of rod ends extending out of the support plate, and a rear opening, a second anterior mechanism having a top opening for receiving a set screw, a front opening for receiving the other one of the pair of rod ends extending out of the support plate, and a rear opening, a first rod inserted into the rear opening of the first anterior mechanism and extending between the first anterior mechanism and a first rear mechanism and a spring inserted over the first rod between the first anterior mechanism and the first rear mechanism, a second rod inserted into the rear opening of the second anterior mechanism and extending between the second anterior mechanism and a second rear mechanism and a spring inserted over the second rod between the second anterior mechanism and the second rear mechanism, a first Z-clip for insertion into the first rear mechanism and a first buccal tube, and a second Z-clip for insertion into the second rear mechanism and a second buccal tube. In yet another form of the present disclosure, a dental repositioning device is disclosed which comprises a support plate having a first rod embedded therein and extending out of the support plate adapted for placement on a tooth and a second rod embedded therein and extending out of the support plate adapted for placement on another tooth, a first anterior mechanism having a top opening for receiving a set screw and a rear opening, a second anterior mechanism having a top opening for receiving a set screw and a rear opening, a first rod embedded in the support plate and extending between the first anterior mechanism and a first rear mechanism and a spring inserted over the first rod between the first anterior mechanism and the first rear mechanism, a second rod embedded in the support plate and between the second anterior mechanism and a second rear mechanism and a spring inserted over the second rod between the second anterior mechanism and the second rear mechanism, a first Z-clip for insertion into the first rear mechanism and a first buccal tube, and a second Z-clip for insertion into the second rear mechanism and a second buccal tube. In light of the foregoing comments, it will be recognized that the present disclosure provides a dental repositioning device for use in orthodontic procedures to correct positioning of teeth within a mouth of a patient. The present disclosure provides a dental repositioning device that can be easily employed with highly reliable results to be placed on teeth to exert a force on teeth to reposition teeth within a mouth of a patient. The present disclosure also provides a dental repositioning device that may be used to align teeth in incremental treatments. The present disclosure further provides a dental repositioning device that may be temporarily placed on teeth to reposition teeth within a mouth of a patient. The present disclosure provides a dental repositioning device that requires only a single tool for repositioning the device on teeth. The present disclosure provides a dental repositioning device that is comfortable to wear and simple to manage. The present disclosure is also directed to a dental repositioning device that can be used to mesialize a molar. The present disclosure provides a dental repositioning device that is placed inside the mouth, is not bulky, and has few moving parts. The present disclosure is also directed to a dental repositioning device that has a wrench device for rotating a set screw for biasing the device. The present disclosure provides a dental repositioning device that has an elastic nickel titanium spring that can maintain a consistent 200 grams of force to assist in repositioning a tooth in the mouth of a patient. These and other advantages of the present disclosure will become apparent to those skilled in the art after considering the following detailed specification in conjunction with the accompanying drawings.
