Description

Technical Field

[0001] The utility model relates to the technical field of oral dental mechanical medical treatment, in particular to a jaw pad type posterior teeth traction device component and a jaw pad type posterior teeth traction device. Background Art

[0002] Posterior teeth lock is very common in clinical practice, and lock can be divided into positive lock and negative lock in clinical practice. Positive lock means that the lingual bevel of the lingual tip of the maxillary posterior teeth is located on the buccal side of the buccal bevel of the buccal tip of the mandibular posterior teeth, and there is no occlusal contact on the occlusal surface, which is more common in clinical practice; negative lock means that the buccal bevel of the buccal tip of the upper posterior teeth is located on the lingual side of the lingual bevel of the lingual tip of the lower posterior teeth, and there is no occlusal contact on the occlusal surface, which is less common in clinical practice. Since the locked teeth have no normal chewing function, the patient can only use the posterior teeth on the non-locking side for unilateral chewing, which reduces the chewing function and affects normal life, so it is necessary to correct the posterior teeth lock.

[0003] The traditional treatment plan is to correct it by alternately pulling the upper and lower teeth. If the patient's lock is severe, the alternate pulling can easily cause occlusal trauma and lead to loose teeth. The alternate pulling of the upper and lower posterior teeth can easily cause the side effect of elongating the maxillary posterior teeth. Utility Model Content

[0023] See also Figures 1 to 3 A jaw pad type posterior teeth traction device assembly in the first embodiment of the utility model includes a jaw pad base 10 and a lingual side buckle 40.

[0024] The jaw pad base 10 is adapted to the inner side of the dentition, and the jaw pad base 10 includes a first jaw pad portion 11 corresponding to the anterior tooth area, and a second jaw pad portion 12 and a third jaw pad portion 13 respectively arranged on both sides of the first jaw pad portion 11, and the jaw pad type posterior teeth traction device assembly also includes an interproximal hook assembly 20 for fixing the jaw pad base 10, and the interproximal hook assembly 20 includes a plurality of first interproximal hooks 21 spaced apart from each other on the first jaw pad portion 11, and the first interproximal hooks 21 include a fixing portion 211 embedded in the jaw pad base 10, and a hook portion 211 formed by extending from one end of the fixing portion 211 toward one side of the tooth root. 12. The jaw pad type posterior teeth traction device assembly also includes a traction arm 30 fixed on the second jaw pad portion 12 and / or the third jaw pad portion 13, the traction arm 30 includes a force-bearing portion 31 embedded in the jaw pad base 10, and a ring portion 32 formed by extending from one end of the force-bearing portion 31 toward a side away from the root of the tooth, the lingual buckle 40 is arranged on the molar, the traction arm 30 and the lingual buckle 40 are traction-connected by an elastic member 50, and the interproximal hook assembly 20 also includes a second interproximal hook 22, and the second interproximal hook 22 is arranged at intervals on the second jaw pad portion 12 and / or the third jaw pad portion 13.

[0025] Preferably, the inter-proximal hook assembly 20 includes a first inter-proximal hook 21 and a second inter-proximal hook 22, both of which have the same functional structure.

[0026] When wearing, the jaw pad base 10 is fitted and contacted with the inner side of the dentition, and the first interproximal hook 21 is buckled between the teeth. At this time, the hook portion 212 of the first interproximal hook 21 passes between the canines, and the ball portion set at one end of the hook portion 212 is pressed against the outer side of the dentition. The jaw pad base 10 is pressed against the inner side of the dentition, so that the first interproximal hook 21 is firmly hooked on the tooth. Similarly, the second interproximal hook 22 is also hooked on the tooth. Under the pulling action of the interproximal hook component 20, the jaw pad base 10 is fixed to the inner side of the dentition, wherein one end of the hook portion 212 is pressed against the outer side of the dentition. The spherical head increases the gripping force on the outer side of the dentition and makes it more comfortable to wear, avoiding trauma caused by friction; and because the fixing portion 211 of the first interproximal hook 21 is embedded in the jaw pad base 10, the L-structured support portion 23 formed by the extension of the fixing portion 211 can prevent the first interproximal hook 21 from rotating and falling off in the jaw pad base 10, and also increase the force-bearing area between the first interproximal hook 21 and the jaw pad base 10, so that the jaw pad base 10 can provide good support for the traction arm 30 on the inner side of the dentition.

[0027] Preferably, the jaw pad base 10 is made of resin, and the elastic member 50 is a rubber ring.

[0028] See also Figure 3In this example, the traction arm 30 is installed on the third jaw pad part 13. After the jaw pad base 10 is fixed, the traction arm 30 is located between the gaps of the posterior teeth that need to be corrected, wherein the force-bearing portion 31 in the traction arm 30 is along the gap between the teeth and across the gap between the teeth to the outside of the teeth and connected to the ring portion 32. The ring portion 32 is located on the outside of the posterior teeth, but does not abut against the outside of the teeth. Then, the elastic member 50 fixed on the lingual side is connected to the ring portion 32 of the traction arm 30 across the teeth. At this time, the elastic member 50 transmits the pulling force for correcting the locking to the traction arm 30, and the traction arm 30 transmits the force to the fixed jaw pad base 10, so that the posterior teeth have an outward pulling force, thereby achieving correct locking. Among them, the force-bearing portion 31 of the traction arm 30 is set in a U shape, embedded in the jaw pad base 10, and increases the force between the traction arm 30 and the jaw pad base 10.

[0029] In summary, in the above embodiments of the present invention, a new type of jaw pad type posterior teeth traction device assembly is provided, wherein the jaw pad resin base is fixed to the inner side of the dentition, and the locking of the molars is corrected by the elastic force of the traction arm 30 and the lingual buckle 40 on the elastic member 50 .

[0030] See also Figure 4 The difference between a jaw pad type posterior teeth traction device assembly in the second embodiment of the utility model and a jaw pad type posterior teeth traction device assembly in the first embodiment is that: this embodiment can also treat bilateral locking. When locking occurs on both the second jaw pad portion 12 and the third jaw pad portion 13, traction force arms 30 can also be installed on both the second jaw pad portion 12 and the third jaw pad portion 13.

[0031] See also Figure 5 The difference between a jaw pad type posterior teeth traction device in the third embodiment of the utility model and a jaw pad type posterior teeth traction device assembly in the first embodiment is that: the present embodiment can also treat the correction of occlusion of other teeth. When the patient needs to correct other teeth before installing the jaw pad type posterior teeth traction device assembly, it is only necessary to embed the traction hook 60 in the jaw pad base 10 of the jaw pad type posterior teeth traction device assembly, and install the adhesive hook 70 on the other teeth that need to correct occlusion. The traction hook 60 and the adhesive hook 70 are elastically connected with the elastic member 50, which can also correct the other teeth.

[0032] The fourth embodiment of the present embodiment provides a jaw pad type posterior teeth traction device, comprising a jaw pad type posterior teeth traction device assembly of any one of the first to second embodiments, the jaw pad type posterior teeth traction device also includes a traction hook 60 and an adhesive hook 70, the traction hook 60 is embedded in the jaw pad base 10, the adhesive hook 70 is arranged on the other teeth, and the traction hook 60 and the adhesive hook 70 are connected by an elastic member 50.
