Description
Technical Field
The utility model belongs to the technical field of orthodontic technology and specifically relates to an it prevents removal combined movable correction ware to assist dental arch extension.
Background
An appliance is a device for treating dental deformities, or orthodontic appliance. It can generate acting force, or the functional acting force of the perioral muscles of the masticatory muscles can change the deformed frontal bone and dislocated teeth by the periodontal support tissue by the appliance, so as to be beneficial to the normal growth and development of the dentognathic face.
The existing appliance is only suitable for patients with deep draping and maxillary protrusion, and has limited arch expansion force, so that the appliance needs longer correction time and is complex to adjust, and the wearing comfort of the patients is greatly influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the existing problems, the utility model provides a movable appliance which is used for expanding and preventing the movable combination of the auxiliary dental arch matched with the fixed bracket.
The technical scheme of the utility model is that: the utility model provides an supplementary dental arch extension prevents removing combined movable appliance, includes base bracket, horizontal palate post, left molar belt ring, right molar belt ring, left NC arch and right NC arch, left molar belt ring and right molar belt ring pass through horizontal palate post and connect, and horizontal palate post left end is provided with left NC arch, and horizontal palate post right-hand member is provided with right NC arch, and left NC arch and right NC arch symmetry set up in horizontal palate post top and fix respectively in the base bracket.
The arch part of the left NC bow and the arch part of the right NC bow are respectively exposed out of the base.
And a first traction hook is fixed on the base.
The first towing hook is positioned between the left NC bow and the right NC bow.
And a second traction hook is arranged on the transverse palate rod and close to the right molar belt ring.
The second draw hook type portion faces downward.
The middle part of the cross palate rod is arranged into an arch structure which is bent upwards.
And adjusting and connecting devices are respectively arranged on the outer sides of the left NC bow and the right NC bow.
The utility model has the advantages that:
1. the utility model of the movable appliance for assisting dental arch expansion and preventing movement combination can assist the fixed bracket to carry out anchorage of anterior adduction and prevent the posterior molar from moving back and forth and far and middle by arranging the left NC arch and the right NC arch on the cross palate rod; meanwhile, the left NC arch and the right NC arch can assist the fixed bracket to expand the whole dental arch outwards, so that the dental arch is more full;
2. the auxiliary dental arch expansion movement-prevention combined movable appliance of the utility model can lead different single dentition to be irregular and be adducted by adding the traction hook on the base, thus leading the dentition to be more orderly;
3. the utility model discloses an supplementary arch of tooth extension prevents to remove combined movable appliance, can combine together the use with traditional fixed the correction, realizes the combination of a plurality of functions, adjusts simply, need not repetitious manufacture and wears many times, lets treatment cycle reduce, improves the patient and wears the comfort.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, base; 2. a cross palatal bar; 201. the middle part of the cross palate bar; 3. a left molar band; 4. a right molar belt ring; 5. a left NC bow; 6. a right NC bow; 7. a first towing hook; 8. a second towing hook; 9. adjusting the connecting device; 10. an arcuate portion.
Detailed Description
The invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, the combined movable appliance for assisting dental arch expansion and preventing movement comprises a base support, a cross palatal bar, a left molar band, a right molar band, a left NC arch and a right NC arch, wherein the left molar band and the right molar band are connected through the cross palatal bar, the left NC arch is arranged at the left end of the cross palatal bar, the right NC arch is arranged at the right end of the cross palatal bar, and the left NC arch and the right NC arch are symmetrically arranged above the cross palatal bar and are respectively fixed in the base support.
The arch part of the left NC bow and the arch part of the right NC bow are respectively exposed out of the base, so that the correction by matching with an external device is facilitated, and the correction period is shortened.
And a first traction hook is fixed on the base and used for assisting different single dentition in adduction.
The first towing hook is positioned between the left NC bow and the right NC bow.
A second traction hook is arranged on the transverse palate rod and close to the right molar belt ring, the hook-shaped part of the second traction hook faces downwards, and the second traction hook is used for assisting in adjusting a single posterior molar so that the originally crowded dentition has enough space for correction.
The palatal bar is centrally disposed in an upwardly curved arch that expands to fit the upper left and right NC arches while providing sufficient anchorage.
And the outer sides of the left NC bow and the right NC bow are respectively provided with an adjusting and connecting device, and the adjusting and connecting devices are adjusting and connecting devices of movable appliances in the existing market.
The above, only do the preferred embodiment of the present invention is not used for limiting the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
