Description

Correction of mandibular retrusion deformity with anti-labial inclination of upper anterior teeth and double splint appliance

technical field

The utility model relates to the technical field of a double splint orthotic, and relates to a lower splint and a double splint orthotic for correcting mandibular retrusion deformity with an anti-lip tilting of upper anterior teeth.

Background technique

The double splint appliance is currently commonly used in orthodontic clinics, and it is a functional appliance for patients with mandibular retrusion who still have growth potential;

The double splint appliance utilizes the developmental potential of the patient to inhibit the development of the upper jaw while promoting the growth of the mandible, so that the relationship between the upper and lower jaws tends to be normal, so that the patient has a more coordinated and beautiful appearance and dental occlusal relationship; the current clinically recognized occlusal splint There are three main types of aligners, Activator aligner, Herbst aligner, and Twinblock aligner; Activator aligner needs to be remade to guide the mandible, which increases the cost of orthodontic treatment; Herbst aligner is a fixed aligner with adhesive tape The appliance can guide the mandible in stages, but the unique structure of the appliance makes it difficult for patients to maintain oral hygiene, and it is relatively more prone to damage to the appliance; compared with the above two types, the Twinblock appliance can not only The mandible is leading, and the comfort is better, basically does not affect the oral function of the patient. A well-made appliance can even be worn while eating, which can fully meet the requirements for the wearing time of the appliance; but the operation of the Twinblock appliance is time-consuming , it is very irritating, and it is not suitable to be performed directly beside the chair. When it is necessary to guide again, a new appliance must be completely remade. What is more important is that it is difficult to accurately control the amount of mandibular advancement; therefore, for the clinical problems of the Twinblock appliance, currently A spiral expander push-type occlusal pad Twinblock appliance was introduced in China. The appliance is equipped with a metal occlusal pad with a spiral expander, which can precisely control the amount of mandibular leading, and realize the step-by-step multiple method of leading the mandible; The metal jaw pad can be moved forward by 0.1mm every time the helical arch expander rotates 90 degrees, and can be operated beside the chair; by controlling the initial leading amount, the patient's discomfort is reduced and the patient's cooperation is increased; there is no need to completely remake a new correction when leading again It is convenient for doctors and patients; however, it is found during use that the back teeth of the child will be raised during the wearing process, so that the front teeth do not touch; in this state, the lower front teeth of the patient will elongate upward; elongate When the lower anterior teeth occlude with the palatal neck of the upper anterior teeth, the occlusal lateral force will be increased, causing the upper anterior teeth to incline labially; and if the lip inclination is too large, it will lead to protruding teeth, resulting in tooth deformity, and further It affects the protrusion of the maxillofacial region; in addition, there are occasional cases where the screw part of the helical arch expander in the maxillary molar area falls off, which affects the treatment effect, and it is necessary to return to the last applied force to prolong the treatment time.
