Abstract
The invention relates to an adjustable maxillary molar palatal tractor for correcting the buccal malposition of maxillary molars, belonging to the technical field of medical instruments. The tractor mainly structurally comprises dual-side abutment teeth bands, a palatine arch, a U-shaped adjusting curve, a towing hook and a crisscross-welded reinforcing point. The adjustable maxillary molar palatal tractor has the characteristics that firstly, the position of the towing hook can be determined according to the specific situation of malposition teeth so as to realize the high-efficiency correction and effective control on the malposition teeth; secondly, the size and direction of traction can be necessarily adjusted in time by adjusting the U-shaped adjusting curve; thirdly, by virtue of the crisscross-welded reinforcing point, the rigidity of the U-shaped adjusting curve and the towing hook behind can be improved so as to avoid stress deformation; fourthly, the towing hook can be arranged at the single side and both sides so as to be respectively applicable to correction on the buccal malposition of maxillary molars at the single side and both sides; and fifthly, the malposition teeth can be pulled and stressed only by adhering a traction button with small size, and therefore, the adjustable maxillary molar palatal tractor can be applicable to cases with deficient exposure of malposition teeth crowns.
Description
Technical field
What the present invention relates to is a kind ofly to grind one's teeth in sleep palate to traction apparatus for correcting on grind one's teeth in sleep in the buccoversion adjustable.Belong to technical field of medical instruments.
Background technology
The buccoversion of maxillary molar is clinically common misfit deformity.Since on grind one's teeth in sleep the dislocation eruption in the cheek side of upper dental arch, cause it to destroy with antagonist and with the normal relation of adjacent teeth, might bring out multiple illness thus, endanger function and the health of stomatognathic system.
Particularly, the main harm of this deformity has
The malposed tooth forfeiture concerns with the normal occlusion of corresponding lower molar, loses masticatory function
The normal syntopy of malposed tooth and its adjacent teeth is destroyed, and causes food impaction easily, causes the infringement of periodontal tissue.
Malposed tooth has been lost self-cleaning action owing to lose function, and tooth body dental pulp pathological changes system takes place easily
Bring out temporomandibular joint disease
At present, the appliance of grinding one's teeth in sleep in this buccoversion and antidote mainly contain ordinary fixed orthodontic appliance, the common fixed traction apparatus of grinding one's teeth in sleep, plantation nail and the direct counter extensioin etc. of grinding one's teeth in sleep up and down.
But above-mentioned appliance and antidote have used its deficiency.
Wherein, the deficiency of ordinary fixed orthodontic appliance is:
Need lay band or bonding buccal tube grinding one's teeth in sleep of cheek side dislocation, can't be used for corona and expose not enough case.
The size and Orientation of corrective force is difficult to accurate control.
Easily compressing closes on soft tissue, causes iatrogenic injury.
The anchorage deficiency.
The main deficiency of the common fixed traction apparatus of grinding one's teeth in sleep is:
During use, the direction of pull strength can't be according in addition corresponding adjustment of the progress of correcting.
Yielding displacements such as the parts of this kind appliance such as drag hook, the compressing gingiva causes the patient suffering.
The deficiency of plantation nail is:
Wound is arranged,
Be easy to come off and fracture after the plantation nail is stressed
Clinical manipulation inconvenience
Be not suitable for the patient that bleeding tendency is arranged.
The main deficiency of direct counter extensioin of grinding one's teeth in sleep up and down is: grinding one's teeth in sleep up and down is subjected to elongation easily behind the pull strength, easily causes postoperative to have only this interlock contact of having ground one's teeth in sleep up and down, and mouthful in other tooth can't interlock serious consequence.
Summary of the invention
What the present invention proposed is that a kind of the rectification on grind one's teeth in sleep in the buccoversion adjustable ground one's teeth in sleep palate to traction apparatus, its objective is to overcome the inherent shortcoming of appliance and antidote in the past, finishes the infringement of avoiding when correcting target the patient.
The palate of grinding one's teeth in sleep on adjustable comprises to the structure of traction apparatus:
U-shaped adjusting is bent
Characteristics of the present invention:
Palatine arches and bilateral abutment band weld together
The extension of palatine arches forms drag hook in the palate side of grinding one's teeth in sleep of buccoversion
The position of drag hook can be determined according to the concrete condition of malposed tooth.Can guarantee that so the size and Orientation of pull strength is fit to the needs of rectification, thereby realize the efficient rectification of malposed tooth and effectively control.Prevent in the correcting process, because the direction of the pull strength that applies and size are incorrect, cause malposed tooth that disadvantageous movement takes place.
The place ahead of drag hook is curved to have U-shaped adjusting bent: the rectification progress that can grind one's teeth in sleep according to dislocation in correcting process, by this U-shaped necessity adjustment of regulating song is realized size, the direction of pull strength are regulated timely, thereby strengthen the control to whole correcting process, avoid going wrong.
The arch wire of U-shaped adjusting Qu Qianfang and the infall of palatine arches arch wire are welded together to form decussation reinforcement of weld point, and this can effectively increase the rigidity of U-shaped adjusting song and subsequent drag hook, the bent and drag hook stress deformation of U-shaped adjusting when avoiding drawing.
Hook can arrange one-sided and bilateral, is applicable to the rectification of the cheek side dislocation of grinding one's teeth in sleep on one-sided and the bilateral respectively.
Owing to only need the very little traction button of a bonding volume just can draw reinforcing to it on the malposed tooth, expose not enough case so the present invention goes for the malposed tooth corona.
Using method:Palate lists with the binding agent cementation upper tooth the patient in place to traction apparatus with grinding one's teeth in sleep on adjustable.The occlusal surface bonding traction button of on buccoversion, grinding one's teeth in sleep then.Draw to placing the elasticity chain ring between the drag hook of traction apparatus at this traction button and the palate of grinding one's teeth in sleep.Grind one's teeth in sleep in the buccoversion under the effect of this pull strength, dental arch is included in playback in gradually.
Description of drawings
Fig. 1 is the structural representation of palate to traction apparatus of grinding one's teeth in sleep on adjustable
Each mark is respectively 1 abutment band among the figure, 2 palatine arches, and 3 U-shaped adjustings are bent, 4 hook frames, 5 decussation reinforcement of weld points, the welding section that 7 abutment bands and palatine arches are welded together to form
This figure is that the bilateral type is ground one's teeth in sleep palate to traction apparatus on adjustable, and both sides have and have the U-shaped bent drag hook of regulating, and are applicable to the patient of the buccoversion of grinding one's teeth in sleep on the bilateral.
Grind one's teeth in sleep palate to traction apparatus on one-sided type is adjustable, then only be shaped on U-shaped at a lateral bending of dental arch and regulate bent drag hook, be applicable to the patient of the buccoversion of grinding one's teeth in sleep on one-sided.
