CN103230306A - Ring frame type molar uprighter for correcting mandibular molars suffering forward lower impaction - Google Patents

Abstract

The invention provides a ring frame type molar uprighter for correcting mandibular molars suffering forward lower impaction, belonging to the technical field of medical instruments. The uprighter mainly comprises (1) a front tooth section bracket, (2) a hyoid arch, (3) abutment bands on both sides and (4) ring frames with draw hooks, wherein the ring frames are formed by extension of the hyoid arch and are arranged around the molars suffering forward lower impaction. The uprighter has the characteristics that (1) the ring frames with the draw hooks are welded together with the abutment bands via welding spots on the sides of cheeks and a tongue, are not provided with free ends, are not easy to deform and shift after being stressed and press the gingival tissues; (2) the front tooth section bracket formed by wrapping the front section of the hyoid arc with self-curing plastics is tightly fit with the lingual surfaces and lower alveolar crest of the lower front teeth, and the reacting force caused by the correction force is jointly borne by the lower front teeth and the lower alveolar cavity, thus avoiding the unfavourable shift easily happening after teeth such as abutments and the like are subjected to the reacting force; and (3) when the ring frames with the draw hooks are bent, the positions of the draw hooks can be determined according to the specific conditions of the offending teeth so as to achieve efficient uprighting and effective control of the offending teeth.

Description

The ring frame the corrected vertical device of grinding one's teeth in sleep of grinding one's teeth in sleep under the impaction of low site is used for leaning forward

Technical field

What the present invention relates to is a kind of for the rectification ring frame of grinding one's teeth in sleep under the impaction of low site vertical device of grinding one's teeth in sleep that leans forward.Belong to technical field of medical instruments.

Background technology

The impaction of low site that leans forward of lower molar is clinically common misfit deformity.Because the appearance of the position of grinding one's teeth in sleep and attitude is unusual down, cause itself and adjacent teeth and antagonistic normal relation to destroy, can bring out multiple illness, function and the health of harm stomatognathic system.

The main harm of this deformity has Cause suffering from the tooth body dental pulp pathological changes of tooth self and adjacent teeth

Cause the periodontal disease damage Destruction posterior occlusion relation Bring out temporomandibular joint disease

Be used for this kind malformation correction at present multiple appliance is arranged: as conventional fixed appliance, uprighting spring, cantilever bow, the fixed vertical device of grinding one's teeth in sleep, plantation nail etc.

Said method has its deficiency owing to characteristic and its structural reason of appliance.

Wherein, the deficiency of appliances such as conventional fixed appliance, uprighting spring, cantilever bow is:

Need lay band or bonding buccal tube at the trouble tooth of the low level that leans forward, 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 fixed vertical device of grinding one's teeth in sleep is:

During use, yielding displacements such as the parts of appliance such as drag hook, the compressing gingiva causes the patient suffering;

The anchorage deficiency, when the trouble tooth was applied corrective force, because counteracting force does not obtain balance firmly, disadvantageous movement and change took place in position and attitude that other teeth such as abutment often occur.

The deficiency of plantation nail is: Wound is arranged, Be easy to come off and fracture after the plantation nail is stressed Some position is planted nail as the back zone etc. of grinding one's teeth in sleep owing to the reason on dissecting often is unsuitable for planting putting.

Summary of the invention

The present invention proposes is a kind of ring frame of impaction of low site vertical device of grinding one's teeth in sleep that leans forward of grinding one's teeth in sleep of correcting down, its objective is to overcome the inherent shortcoming of appliance in the past, avoids the infringement to the patient when finishing the rectification target.

The grind one's teeth in sleep structure of vertical device of ring frame comprises:

Labial teeth section support holder

Hyoid arch is that 1 millimeter dental stainless steel silk bends and forms with diameter.

Bilateral abutment band

Formed by hyoid arch continuity, be positioned at the band drag hook ring frame of the impaction of low site that leans forward around grinding one's teeth in sleep

Characteristics of the present invention:

Solder joint and the abutment band of ring frame by cheek, tongue side of band drag hook welds together, and do not have free-end, stressed after not yielding displacement, oppress gingiva tissue.

The labial teeth section support holder that is formed by self curing plastic parcel hyoid arch leading portion is closed with the close card of following alveolar ridge with the lingual surface of following labial teeth, born jointly by following labial teeth and following alveolus by the counteracting force that corrective force causes, this has just been avoided teeth such as abutment to be subjected to the unfavorable movement that occurs easily behind the counteracting force.

When bending band drag hook ring frame, the position of drag hook can be determined according to the concrete condition of suffering from tooth, realizes the vertical and effectively control to the efficient of suffering from tooth.

 

Using method: it is in place on patient's mandibular dentition to encircle the frame vertical device cementation of grinding one's teeth in sleep.Then at the impaction of low site that leans forward the following bonding tongue side button of grinding one's teeth in sleep.Grind one's teeth in sleep at this tongue side button and ring frame and to place the elasticity chain ring between the drag hook of vertical device and draw.The following of impaction of low site that lean forward ground one's teeth in sleep under the effect of this pull strength, obtains gradually vertically.

Description of drawings

Fig. 1 is the grind one's teeth in sleep structural representation of vertical device of ring frame

Each mark is respectively among the figure: the 1st, and labial teeth section support holder, the 2nd, hyoid arch, the 3rd, abutment band, the 4th, cheek face down bonding contact, the 5th, ring frame, the 6th, drag hook, the 7th, tongue face down bonding contact.

This figure is the bilateral type ring frame vertical device of grinding one's teeth in sleep, and there is the ring frame that has drag hook both sides, is applicable to the bilateral patient of impaction of low site of leaning forward that grinds one's teeth in sleep.

The one-sided type ring frame vertical device of grinding one's teeth in sleep only has the ring frame of band drag hook in a side of dental arch, be applicable to the lean forward patient of impaction of low site of one-sided backteeth.

Claims (2)

1. the ring frame vertical device of grinding one's teeth in sleep be used for to be corrected the following of impaction of low site that lean forward and is ground one's teeth in sleep.

2. its primary structure comprises:

Labial teeth section support holder,

Hyoid arch,

Bilateral abutment band,

Formed by hyoid arch continuity, be positioned at the band drag hook ring frame of the impaction of low site that leans forward around grinding one's teeth in sleep.
