Description

Bracket-free invisible appliance for correcting orthodontic locking and occlusal occlusion of molar

Technical Field

The utility model belongs to the stealthy field of correcting of dentistry's tooth deformity, concretely relates to ware is rescued to stealthy ware of rescuring without holding in palm groove of orthodontia.

Background

Orthodontics is a clinically common malocclusion, i.e., the palatal apex of a maxillary molar is in occlusal contact with the buccal apex of a mandibular molar, most commonly occurring in the second molar. Such malocclusion deformity may cause reduction of occlusion contact area to reduce chewing efficiency, and the waste side lacks self-cleaning function, susceptible to caries and periodontal disease, and may form occlusion interference in molar region to obstruct lateral movement of mandible, which may induce temporomandibular joint disorder in the long term, and seriously affect physical and mental health of patients, so it should be treated as soon as possible.

The method for correcting molar occlusion clinically mainly comprises an upper molar interaction traction method and a lower molar interaction traction method and a nail implantation method. The interactive traction method is characterized in that lingual buttons are bonded on the buccal side of the upper jaw second molar and the lingual side of the lower jaw second molar, and traction is performed through rubber bands. However, the lower jaw molars of the patient are in the tongue inclined position, so the tongue side buckles are not easy to be bonded and the comfort level of the patient is low. Meanwhile, the stretching of the molar teeth is easily caused by the mutual traction, and the vertical control of a patient is not facilitated, especially for a high-angle patient. The application of the implant nail can offset the vertical component force, and effectively avoid the elongation of the molar. Along with the improvement of requirements on beauty, comfort and the like in the orthodontic process, more and more orthodontic patients select bracket-free invisible correction. For bracket-free invisible correction of second molar orthodontics, the window is opened on the tooth surface of the locking jaw, and the side buckle of the bonding tongue is subjected to interactive traction. However, the integrity of the invisible appliance is damaged by windowing, and the wrapping performance of the second molar and the overall fitting degree of the tooth socket are affected.

The patent publication No. CN210330780U discloses a customized cross palatal bar device for relieving molar occlusion, which comprises a customized belt ring fixed on teeth, wherein a customized cross palatal bar is connected to the middle of the customized belt ring sleeved on the teeth on two sides, two ends of the customized cross palatal bar extend to form a main bar fixedly connected with the customized belt ring and an auxiliary traction bar hooked with the buccal side buckle of the customized belt ring, the auxiliary traction bar and the buccal side buckle of the corresponding customized belt ring are connected with a chain-shaped rubber ring, and two ends of the chain-shaped rubber ring are respectively hooked on the buccal side buckle and the auxiliary traction bar of the customized belt ring. In actual use, the cross palate rod occupies the oral space of a patient, the swallowing of the patient is affected, and the wearing comfort of the patient is low.

In order to solve the problems, the inventor designs a novel high-efficiency bracket-free invisible appliance for correcting the orthodontics of the second molar.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome current defect, provide a orthodontics lock tooth and close unscrambler, adopt elasticity correction mode, soft orthodontic teeth, the patient wears pleasing to the eye, the comfort level is high, can effectively solve the problem in the background art.

In order to realize the above-mentioned purpose, the utility model provides a ware is rescued to no support groove stealthy of orthodontic locking, including the tooth correction ware, the lingual side of the upper jaw purpose molar of tooth correction ware and palatal side kind implant nail pull through the rubber band, pull through the rubber band interaction between the lingual side of the buccal side of the upper jaw purpose molar and the lower jaw purpose molar, the preceding or the back tooth position of upper jaw purpose molar sets up the jaw pad.

Furthermore, the lingual side and buccal side surfaces of the molars of the maxillary objective are respectively provided with a convex point, a groove is formed in the gingival side and the occlusal side of the convex point on the buccal side, the lingual side surface of the molars of the mandibular objective is provided with a convex point, a groove is formed in the gingival side of the convex point, and the rubber band is clamped and hooked in the groove of the convex point.

Further, the upper jaw purpose molar is an upper jaw second molar, the lower jaw purpose molar is a lower jaw second molar, and a jaw pad is arranged at the position of the upper jaw first molar.

Furthermore, the convex surface of the salient point is a smooth curved surface.

Furthermore, the salient points and the tooth appliance body are of an integrated structure.

Compared with the prior art, the utility model has the advantages that:

the dental appliance is provided with a jaw pad at the first molar position of the upper jaw for separating occlusion. The rest teeth are covered by the transparent appliance, which is beneficial to preventing the elongation of the teeth. Round salient points are respectively arranged on the buccal side and the lingual side surfaces of the second upper jaw molar, and gingiva sides and lingual side salient points are provided with slots in the occlusal sides of the salient points on the buccal side so as to facilitate the placement of the rubber band. Meanwhile, salient points are arranged on the lingual side of the second lower jaw molar, and the slotting position is positioned in the gingival direction; the convex points on the buccal side of the upper jaw and the lingual side of the lower jaw are alternately drawn by rubber bands, and the convex points on the lingual side of the upper jaw and the implanted nails on the palatal side are drawn to prevent the extension of the upper jaw molars and accelerate the correction of orthodontics. The ware body is rescued with the tooth to the bump and is integrated structure and avoids destroying and rescues the ware wholeness, and circular design improves the patient greatly and wears pleasing to the eye degree and comfort level. And the whole correction process does not need to be adhered or the traction button is removed, so that the damage to the enamel surface of the teeth is effectively reduced.
