Description

Tooth corrector

Technical Field

The utility model relates to a tooth appliance, in particular to a tooth appliance for correcting the malposition of anterior teeth occlusion, which is used for deep overlying of anterior teeth or inverse deciduous teeth.

Background

Currently, the malocclusions can be medically classified into various symptoms, including deep occlusions, deciduous teeth, and the like.

Deep occlusion of anterior teeth, also called deep bite, is a common malocclusion in clinic due to excessive eruption of anterior teeth. The common correction method comprises fixing the correction device, bonding a bracket on the tooth, inserting a correction arch wire, pressing the correction arch wire into the upper and lower anterior teeth through the elasticity of the arch wire, and correcting deep occlusion. The plane guide plate movable appliance can be used for backing up the occlusion of the front teeth and pressing the lower front teeth into the appliance through the guide plate.

The plane guide plate can have labial thrust to the upper front teeth, so that the upper front teeth are inclined towards the lips, meanwhile, the plane guide plate movable appliance is worn on the palate of a patient, retention devices such as snap rings are needed, foreign body sensation is obvious, discomfort is caused, and pronunciation is also influenced.

The reversed combination of deciduous teeth, also called as the ground wrapped Tian and the pocked teeth, is a common disorder of dentition in children. The odontopathy usually refers to the inward inclination of the anterior teeth and the inward inclination of the lower anterior teeth, and the early treatment effect is better. The conventional treatment method comprises the steps of pushing spring of the upper anterior teeth out of the tongue of the corrected anterior teeth by using a reed of the pad-combined appliance so as to correct the positive and negative combination, guiding the lip of the upper anterior teeth to move by using a mandible combined crown inclined plane guide plate, and promoting the normal development of the upper and lower jaws by using an MRC muscle trainer for orolabial muscle training. The fixed appliance was moved labially over the anterior orthodontic disarticulation by the action of the bracket orthodontic archwire by 2x 4.

The reed pad-combined appliance is fixed by the clamp ring, the teeth are moved by the arch wire stressing mode, the wearing of the appliance feels foreign body, the arch wire stressing or discomfort is caused, the stressing needs to be frequently and periodically re-diagnosed, and the reed stressing and the tooth moving are not easy to control. The mandibular joint crown inclined plane guide plate is generally made of hard plastic, and can form early contact when being stuck on teeth, the occlusion is not suitable, and the teeth are loosened and are not easy to control due to overocclusion. The movable combined crown inclined guide plate is easy to fall off, the correction effect is influenced, and the risk of mistaken swallowing also exists. MRC muscle trainers are not suitable for custom appliances, are not suitable for all patients, and have inaccurate tooth movement, mainly for muscle function adjustment. The discomfort of the infant patients such as mucosa stimulation and the like caused by the early use of the fixed appliance can influence the continuity of treatment by the combination degree, diet and oral hygiene of the infant patients.

SUMMERY OF THE UTILITY MODEL

In order to more add the friendly front teeth interlock dislocation to correct, the utility model provides an integrative unscrambler from top to bottom corrects the position of front teeth about simultaneously through elastic material's resilience force to the deciduous tooth that closes to the front teeth is anti-closes or the dark symptom that closes is corrected. The specific scheme is as follows:

a dental appliance is used for correcting the malposition symptom of the front occlusion of deep overlying front teeth or the inverse deciduous teeth, and comprises a tooth socket which is made of an integrally formed elastic material;

the upper side and the lower side of the tooth socket are respectively provided with a row of a plurality of tooth sockets for embedding the upper front teeth and the lower front teeth which are malposed in the occlusion, and the inner contour of the tooth socket is determined according to the shape and the position of the front teeth which are malposed in the occlusion of a patient;

wherein, the external contour of the anterior teeth after rotating the anterior teeth by taking 2/5 position of the length of the tooth root at the neck part of the anterior teeth of the patient as the rotation center as the internal contour of each tooth socket.

Furthermore, a step is arranged on the front side of the tooth socket and close to the root of the tooth, and a gap is reserved between the inner wall of the front side of the tooth socket at the occlusion part of the deep-covered anterior teeth and the deep-covered anterior teeth for installing a tooth lateral bracket.

Furthermore, the distance between the step in any tooth groove and the current deepest part of the tooth groove is 2-5 mm.

Further, the width of the gap is 2-4 mm.

The patient with the deciduous teeth reversely closed or deeply covered teeth only needs to bite the teeth into the dental appliance, and the teeth are enabled to obliquely move according to the position of the impedance center through the elastic restoring force of the silica gel, so that the deciduous teeth reversely closed or deeply covered teeth of the front teeth are corrected, and the patient feels comfortable to wear. Meanwhile, the design of the occlusion parts at two sides is adopted, so that the problem that the occlusion is too deep and needs to be padded is solved. The two sides are connected to facilitate the wearing of the patient, and meanwhile, a stable biting position can be obtained, so that the patient can be corrected more friendly.
