Description

Tooth rectification bracket removal tool

Technical field

The utility model is related to a kind of bracket removal tools, are applied on orthodontic.

Background technology

The bracket of straightening of teeth is to be sticked to dental surface by bonding agent, and the bottom plate of bracket is and teeth contact, bonding Position.Have disclosed in the pertinent literature of bracket very much, the public can be ZL201120144757.X's with referenced patent number Chinese utility model patent《Tooth orthodontic autolocking bracket system》(notification number CN202051838U), can be with application reference number It is disclosed for 201410252656.2 Chinese invention patent application《The polycrystalline ceramic orthodontic bracket of surface treatment and its manufacturer Method》(notification number CN104146785A).

Want to remove bracket at present, there are two types of methods：

The first with general instrument, for example needle holder and tears bracket pliers open, and head is pointed, than sharp, can clamp At bracket base or bracket some groove, then firmly the bracket for being sticked to facing is pulled off.The disadvantage is that not due to size Certain fitting, stress point are concentrated, and bracket or bracket base can be caused to deform, the bracket disassembled secondary cannot use .

Second, part of the manufacturer be certain a bracket designs be specific to it tear bracket instrument open, this kind of instrument is completely only Tightly coincide with this bracket length and width dimensions, thus can undamaged this bracket of dismounting, but a disadvantage is that can not be general, If it is more money brackets mating, poor universality that then needs more moneys to tear bracket instrument open, cost is higher.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of suitable difference of energy for the above-mentioned state of the art The tooth rectification bracket removal tool of size bracket.

Technical solution is used by the utility model solves above-mentioned technical problem：A kind of tooth rectification bracket dismounting work Tool, including handle and the collet set on handle front end, it is characterised in that the collet includes

Clamping plate, at least two, it can open or be set to handle front end with closing up, aforementioned clamping plate has and bracket shape after closing up The inner ring of adaptation；And

Regulation ring is sheathed on aforementioned clamping plate periphery and can move back and forth, to adjust the size of aforementioned inner ring.

The regulative mode of regulation ring and clamping plate is preferably arranged as follows：The periphery of the clamping plate is equipped with external screw thread, accordingly, institute The inside for stating regulation ring is equipped with the internal thread being adapted to aforementioned external screw thread.

The connection type of clamping plate and handle can be preferably one of following：

The first, the clamping plate is articulated with handle front end.

Second, the clamping plate is integrated with handle, also, the clamping plate opposite handle has elasticity.

Further, the inside of the clamping plate is equipped with the soft backing member that can be contacted with bracket.Soft backing member has elasticity recovery, It is easily deformable, while the abrasion to bracket is reduced when contacting.

Further, the clamping plate closes up rear cylindrical, and inner ring is rectangular.

The clamping plate can be three pieces, four, five or six.

Consideration arch wire can be passed through, offered on the clamping plate for arch wire by groove

Compared with prior art, the utility model has the advantage of：Pass through the mobile collet clamping opening of capable of adjusting of regulation ring Size realizes that dismounting of the removal tool to different model bracket, versatility improve, be conducive to meet multi-purpose content Save cost.In addition, regulation ring is easy to adjust, easy to operate, application easy to spread.
