Description

Support frame and traction device for orthodontic traction

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a support frame and a traction device for orthodontic traction.

Background

With the continuous change of food structure of people, food is more and more refined, the degeneration of teeth is later than that of alveolar bones, the resulting wisdom teeth are more and more stopped, wisdom tooth extraction also becomes one of the most common alveolar surgical operations, but wisdom tooth extraction can generate various complications, such as mandibular fracture and alveolar nerve injury. Research shows that the alveolar nerve under root compression reaches 13-25%, the incidence rate of alveolar nerve injury in the third molar extraction process is 0.35-8.4%, and the incidence rate of permanent alveolar nerve injury after tooth extraction is 1%. The closer distance between the root of the impacted third molar and the lower alveolar nerve on the anatomical structure is the main reason for damaging the lower alveolar nerve in the tooth extraction process.

At present, many researches at home and abroad propose that the embedded mandibular third molar is extracted by combining orthodontic traction with surgical extraction, aiming at reducing the complications of direct tooth extraction. In 2019, students such as Wang wear in the upper jaw and extend to the plywood of left side second molar with right side second molar, extend and draw the hook, draw the puzzlement of hindering living wisdom tooth, through surgery in wisdom tooth buccal side bonding support groove, draw through the jaw, pull 3 months' back on average, the third molar is kept away from down the neural about 1 to 3mm back of alveolus, pulls out the wisdom tooth smoothly. However, in the mode, the upper jaw is worn with the plywood, so that the size is large, foreign body sensation is obvious, the eating and speaking of a patient are influenced, the daily traction time is short, the treatment period is long, and the patient is difficult to wear the rubber band per se and needs the help of family members of the patient. In addition, the bracket is bonded on the third molar of the lower jaw in the mode, the bracket is large in size, difficult to clean, easy to stimulate mucous membrane to be inflamed, and difficult to wear a rubber band. Wane etc. through the mode of surgery, remove lower jaw third molar buccal side hone lamella to third molar buccal side bonding bracket, and in the buccal side bonding bracket of the first molar of maxilla, second molar and third molar, use the upper jaw tooth column to be the anchorage and pull the lower jaw wisdom tooth, pull 3 weeks to 2 months back through the intermaxillary traction, tooth removes about 1 to 3mm, pulls out the lower jaw wisdom tooth again after keeping away from the lower alveolar nerve. All of these methods use the mandibular third molar with an mandibular anchorage traction, but these methods have the following disadvantages. Firstly, such methods all adopt a method of adhering brackets on buccal sides of mandible wisdom teeth, if mucosa and bone cover the mandible wisdom teeth, the mandible wisdom teeth need to be boned, and the brackets have large volume and unsmooth shape, so that the oral hygiene is difficult to maintain, and dental plaque stimulates gingiva for a long time, which easily causes gingival inflammation. Secondly, the methods all use the upper jaw as an anchorage to draw the mandible wisdom teeth, such as an upper jaw bonding bracket, an upper jaw implantation anchorage nail and an upper jaw wearing plywood. The mode of adhering the bracket to the upper jaw is adopted, the upper jaw group teeth are anchorage, the anchorage teeth are easy to extend, and the oral hygiene is difficult to keep; the mode of implanting the anchorage nail is not suitable for patients who refuse to implant the anchorage nail or are difficult to implant the anchorage nail, and the anchorage nail belongs to invasive operation and is high in cost. Some students adopt the internal jaw reactance in addition, pull the lower jaw wisdom tooth, this mode is many at first molar and second molar bonding support groove or band ring, design various draw gear and pull the third molar, all there is following not enough, bonding support groove or band ring etc. produce dental plaque easily, be difficult to keep oral hygiene, produce the oppression to abutment periodontal easily, the easy necrosis of abutment, and adjacent tooth anchorage is not enough, first molar and second molar incline to the lacuna department easily, the adaptation disease is more restricted, the internal jaw reactance only is adapted to the case of slope in the short distance from the center.
