Description

A kind of Improvement type for correcting three classes plate bite leads device before expanding bow joint

Technical field

The utility model belongs to oral cavity the field of medical instrument technology, and in particular to a kind of for correcting three classes plate bite Improvement type leads device before expanding bow joint.

Background technology

IS-One Group III patho-occlusion is clinical common patho-occlusion, studies have shown that bone Group III in population of China The incidence of plate bite not only influences complexion beauty, can also cause the work(such as voice, chewing, nutrient absorption up to 5%~14% Can be abnormal, it is more easy to therefore cause mental disease.The clinical manifestation of Group III patho-occlusion is maxillary retrusion；Mandibular protrusion or on Retrognathia and mandibular protrusion.Skeletal Class III malocclusion treatment mainly has early function to rescue to be fixed and rescue；It is latent without growth The patient of energy can the joint orthognathous treatment of row correction；Slight bone plate bite can carry out the simple tooth property covered up treatment. However, orthognatic surgery Operative risk is big, expense is expensive, treatment time is long, the property covered up treatment beauty, function, stability are bad, because This, it is that currently used functional appliance bone Group III is wrong that early function, which is rescued in conjunction with upper jaw rapid palatal expansion joint Anterior crossbite, The method that tooth closes.But tradition leads device there are some problems before expanding bow joint：After rapid palatal expansion, upper jaw bone width increases, and Sagittal is not to being obviously improved；Before lead after often there is upper procumbency, mandibular rotates clockwise, cause shape of face compared with before rescuing more Difference.

Utility model content

The technical problems to be solved in the utility model is：A kind of Improvement type expansion bow connection for correcting three classes plate bite is provided It leads device before conjunction, solves after tradition expands before bow joint and lead device rapid palatal expansion, upper jaw bone width increases, and sagittal is not to apparent The problem of improvement.

The technical solution of the utility model is：

A kind of Improvement type for correcting three classes plate bite leads device before expanding bow joint, it is characterised in that：Including TPA- Nance bases expand bow device, draw hook, molar band and horizontal palate bar, and the TPA-Nance bases are in fit with labial teeth area Arc shape, is inlaid with expansion bow device on the TPA-Nance bases, and the expansions bow device is stretches inside the TPA-Nance bases Go out, across its leading flank and horizontal two stainless steel wires for stretching to two cheek sides, the end for expanding bow device is equipped with draw hook, institute It states draw hook to be bent by stainless steel wire end, the draw hook is connected with extaloral appliance, and the draw hook coupler body is connected with Molar band, is connected with horizontal palate bar between two molar bands, and the middle part of the horizontal palate bar is equipped with to expanding one side of bow device To the bulge loop of protrusion, the bulge loop is fixed on the expansion bow device.

The draw hook is connect with molar band by welding manner.

The stainless steel wire for expanding bow device is 0.9mm.

The extaloral appliance includes volume pad, chin pocket and connection facebow, and volume pad, downside are connected on the upside of the connection facebow It is connected with chin pocket, the connection facebow of the extaloral appliance is connected by India rubber circle with draw hook.

The molar band is placed at the first molar position of the left and right sides.

The beneficial effects of the utility model are：

Appliance is led before this Improvement type expansion bow joint and increases labial teeth area bone forced area, and Orthodontic force is made to directly act on Maxilla front end is effectively increased the length in sagittal maxillary direction.

Specific implementation mode

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Improvement type for correcting three classes plate bite leads device before expanding bow joint, including TPA-Nance bases 1 expand bow device 2, draw hook 3, molar band 5 and horizontal palate bar 6.The TPA-Nance bases 1 are in and labial teeth The arc shape that area fits, and it is positioned over labial teeth area.Expansion bow device 2 is inlaid on the TPA-Nance bases 1, device 2 is bent in the expansion To be stretched out from the inside of TPA-Nance bases 1, across the stainless of its leading flank and horizontal two 0.9mm for stretching to two cheek sides Steel wire, the stainless steel wire, which is crossed, reaches cheek side in bilateral canine distal, is bent into the draw hook 3 being connect with extaloral appliance 4, described Draw hook 3 is at the canine tooth of lip side.The draw hook 3 includes coupler body and the hook tail being connected with coupler body, the hook tail of the draw hook 3 It is connected with molar band 5 by welding, the molar band 5 is placed at the sixth-year molar position of the left and right sides, two mills Horizontal palate bar 6 is connected between tooth band 5, the middle part of the horizontal palate bar 6 is equipped with to the bulge loop 7 for expanding bow device 2 one side direction protrusion, institute It states bulge loop 7 to be fixed on the expansion bow device 2, forms an entirety, the horizontal palate bar 6 plays connection function, fixed TPA-Nance Base 1 reinforces, and maintains back segment arch width.

The extaloral appliance 4 includes volume pad 8, chin pocket 9 and connection facebow 10, and the upside of the connection facebow 10 is connected with volume Pad 8, downside are connected with chin pocket 9, and the active position of volume pad 8 and chin pocket 9 is the mouths outer portion such as forehead and chin portion respectively, before being the upper jaw The anti-base portion of square draft gear point.The connection facebow 10 is connected by India rubber circle 11 with the coupler body of draw hook 3, to realize The connection of the extaloral appliance 4 and Oral appliances.India rubber circle 11 connects the connecting component production in extra-oral anchorage component and mouth Raw active force exerts a force, and realizes facebow traction.Labial teeth area bone forced area is increased by leading appliance before this improvement, is made Orthodontic force directly acts on maxilla front end, and the bone amount for being effectively increased sagittal maxillary direction increases.
