Description
Technical field
The utility model is related to a kind of orthodontic therapy instrument, more particularly to a kind of fixed expand bends device.
Background technology
Expand bow device also known as dental arch spiral expander, rescuing principle is：It is adjusted by rotary screw and expands bow device, by Orthodontic force
Tooth and alveolar bone are passed to, to expand the width and length of upper mandibular dental arch.
In the prior art, it provides the fixed of Orthodontic force for tooth and expands bow device usually by the facing circle be bonded with tooth, connection
The connecting rod of each facing circle in the same side, sliding sleeve, connection sliding sleeve and the strut of facing circle, the guide rod being connect with sliding sleeve and with cunning
The screw rod composition of set connection.Generally there are following disadvantages for existing fixed expansion bow device：
1, facing circle is the annular being closed, and size is fixed in advance, when facing circle to be mounted on tooth, due to facing
The size of circle usually with teeth patterning mismatch so that facing circle it is difficult to install, it is not easy to the shape of facing circle is squeezed
With tooth contour no-float, especially grind one's teeth in sleep the 5th cusp or grind one's teeth in sleep it is remote in eruption deficiency when, installation process doctor is time-consuming
Arduously, patient is more painful.Simultaneously because the volume of facing circle is larger, comfort level is poor, is also not easy to clean after patient wears, and
And there is also the possibility of injured patient oral cavity hard and soft tissue in therapeutic process.
2, it since the both sides facing circle for expanding bow device is that entirety is sleeved on tooth, usually requires first to place before and after tooth
Divide tooth elastic tape etc., to isolate the gap for placing facing circle, the period is longer, and the patient feels are uncomfortable；It is stitched before and after tooth
Gap is enough, and facing circle is tentatively sleeved on tooth surrounding, after extruding completes, and each facing circle need to be removed from tooth and connected
Bar welds, and each facing circle is made to be connected, and then again welds facing circle and strut, to complete to expand the preparation of bow device.Therefore expand
Preparation process complexity, the period for bending device are long, and patient comfort is poor.
3, since facing circle is the annular being closed, tooth peripheric surface is wrapped completely, orthodontist cannot be simultaneously again in tooth
The buccal aspect of tooth is autonomous, accurately installs the appliances such as orthodontic bracket and arch wire, and correction is installed again after expansion can only be waited for bend
The appliances such as bracket and arch wire start to treat in next step so that orthodontic treatment process is longer.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of tongue side fixation expansion bow device, bent with solving existing fixed expand
Device preparation process is complicated, and installation is fixed difficult, time-consuming and laborious, and making, installation process patient are more painful, comfortable after patient-worn
Property it is poor, be not easy to clean, after installation orthodontist cannot simultaneously again the buccal aspect of tooth it is autonomous, accurately implement correction and control
The technical problems such as treatment.
The utility model tongue side fix expand bow device, include for the left pressure unit Nian Jie with the tongue side flank of tooth of left side tooth,
