Description

Composite device of bracket-free invisible appliance for adduction of anterior teeth by applying force on tongue side

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a composite device of a bracket-free invisible appliance for adduction of anterior teeth by applying force on the tongue side.

Background

The irregular dentition and the crowding of teeth not only influence the appearance and beauty of people, but also cause the problems of difficult thorough cleaning, occlusion interference of occlusion wounds and the like due to poor occlusion relation, not only influence the oral hygiene, but also cause a series of periodontal and temporomandibular joint diseases.

The current principle of the relief method for crowding dentition cases is to create available gaps for aligning dentition, and the following are mainly used: 1. and (5) slicing. The method can create limited gaps, is only suitable for relieving slight crowding, and can damage the original shape of the teeth to a certain extent. For patients susceptible to caries or patients with poor oral hygiene, there is a potential for an increased risk of caries from abraded portions of the enamel. 2. And (5) expanding the bow. The expansion arch is divided into a dental expansion arch and a bony expansion arch, the bony expansion arch is limited by the age and the growth potential of a patient, the realization difficulty is higher, the dental expansion arch is realized by inclining the lip (cheek) of the dental crown and is also limited by the face type and the oral condition, and the obtained gap is limited. 3. The molar teeth are pushed and moved far. This method is limited by the remaining space available for the jaw bone and is only suitable for relieving mild to moderate crowds. 4. And (5) tooth extraction. The space available for tooth extraction is the largest of several methods, and in addition to aligning crowded dentitions, the resulting gap can also be used for a significant amount of anterior adduction, resulting in a significant lateral improvement for the patient.

In the bracket-free invisible correction, anterior teeth are easy to be adducted in an extraction case, the posterior teeth are easy to move obliquely in the mesial direction due to the deficiency of the posterior teeth anchorage, the loss of the posterior teeth anchorage is caused, a large number of gaps cannot be completely used for adducting the anterior teeth and aligning crowded dentitions, and the difficulty in the correction of the extraction case is increased. The existing common solution is to implant an implant anchorage in the buccal alveolar bone of the posterior dental area on both sides of the upper jaw, arrange a traction buckle or use an accessory and a traction arm at the dental socket of the canine dental area on both sides of the upper jaw, and assist in adduction of anterior teeth through elastic traction between an implant nail and the traction arm (traction buckle). Although the method can effectively provide the anchorage adduction anterior teeth, the method is limited by the condition of maxillary buccal alveolar bone, has the risk of loosening the implantation anchorage, is limited by the depth of the vestibular sulcus, has short length of the traction arm, is difficult to help realize the integral adduction of the upper anterior teeth, and simultaneously has the influence on the appearance due to the elastic traction exposed on the labial side.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's is not enough, provides a tongue side application of force adduction anterior teeth's stealthy composite set of rescuring ware in no support groove, can effectively realize anterior teeth adduction and upper jaw plane anticlockwise rotation to reach and improve and rescure efficiency, improve the purpose of rescuring the comfort level.

Furthermore, the traction part comprises a traction arm and a retention vacuole, the retention vacuole is attached to the tongue side of the bracket-free invisible appliance, the retention vacuole is provided with an opening and a slot, the opening is positioned at the top of the retention vacuole, the slot is downwards recessed from the opening, the traction arm is inserted into the slot, and the traction arm is connected with the elastic traction piece.

Further, the retention vacuoles are made of PTU material or PETG material.

Further, the width of the slot is gradually reduced from top to bottom.

Furthermore, the draft arm includes curved bar and the curved hook of interconnect, and the curved bar inserts in the slot, and elastic traction spare is connected with the curved hook.

Further, the height of the opening is close to the gingival margin of the bracket-free invisible appliance.

Further, the draft arm adopts 3D to print to make. The curved traction arm on the palate side can be set to different lengths and shapes according to the shape and height of the palate vault of a patient and correction requirements, the rod parts of the traction arms in different shapes are consistent in size through computer 3D printing and manufacturing, and the rod parts are consistent in size and are matched with the size of the slot in the retention vacuole.

Further, the elastic traction piece adopts a rubber chain or an elastic line.

The utility model discloses a tongue side application of force adduction anterior teeth's stealthy composite set's of unscrambling ware theory of operation connects planting anchorage nail that jaw portion was implanted and inserts the trailing arm in the maintenance vacuole through elastic traction piece, makes progress the anterior teeth district and applys absolute effectual adduction power, can effectively realize the adduction of anterior teeth and the planar three-dimensional directional control of upper jaw. Along with the length change of the traction arm on the palate side and the change of the implant anchorage position, the direction of the traction force can be changed, so that the effective three-dimensional direction control can be realized on the jaw plane.

Compared with the prior art, the utility model, following beneficial effect has:

the utility model discloses a composite set of ware is rescued in stealthy ware of no support groove of anterior tooth is received in tongue side application of force application can be according to the bonding position of doctor's needs nimble selection maintenance vacuole, and the form and the length of the trailing arm of palate side also can change in a flexible way, and the change of trailing arm need not bond again, can not destroy original stealthy form of rescuring the ware in no support groove yet, can not lead to facing not laminating because of extra trailing arm promptly.

The utility model discloses a composite set of ware is rescued in stealthy ware of supporting groove of no of anterior tooth is received in tongue side application of force adduction, plants the anchorage part and is located the jaw, and implant the anchorage and compare in last jaw buccal side alveolar bone district because upper jaw bone volume is more sufficient, and the field of vision is more clear, has higher stability and simple operation nature.
