Description

Positive axle auxiliary device

Technical Field

The utility model relates to a medical field, more exactly is a positive axle auxiliary device.

Background

The bracket-free invisible appliance is a removable transparent elastic plastic appliance, wraps the crown part of a tooth, and achieves the aim of correcting the tooth by designing a sequence of small-range tooth movement in a computer-aided manner. Currently, this technique is widely used in orthodontic clinics.

However, studies have shown that invisible appliances move teeth primarily obliquely and have poor control over the root. In clinic, for some patients with cuspid teeth and molar roots needing to move in the near-far direction, local bonding brackets are often needed, and the long axis (namely the positive axis) of the inclined tooth body is corrected by matching with a segment arch and jaw traction, but the effect is often poor. The conventional bracket or buccal tube at present is bulky, is not beneficial to being used with the invisible orthodontic appliance, and has poor comfort for patients. Partial teeth with serious inclination have poor positive axis effect of the segmental arch.

The buccal tube used by the utility model has smaller volume, and is additionally provided with a traction hook which can be matched with the buccal tube and is used for placing a rubber band; the tail part of the traction hook is thin and easy to bend, and the traction hook is bent back after being inserted into the buccal tube to prevent dislocation; the question mark hook can be directly adhered to the neck of the tooth.

The buccal tube groove 13 has a size of 0.0188 × 0.025. The buccal tube is further provided with a short arm 14, and the tail end of the short arm is provided with a ball body 15.

The towing hook comprises a tail part 21 and a head part 22, wherein the head part is a hook-shaped bent part, the tail part comprises a first part 211, a second part 212 and a third part 213 which are connected with each other, and the diameters of the first part, the second part and the third part are sequentially increased.

The question mark hook includes a fixing portion 31 which can be adhered to the gingival margin of the cuspid or posterior tooth and a hooked portion 32.

The buccal tube of the utility model is composed of 2 mini buccal tubes (groove size 0.018X0.025), 3 free traction hooks with different lengths and 2 left and right paired bondable question mark hooks. The buccal tube bottom plate is attached to the appearance of the neck of the tooth body, so that the cutting area of the invisible tooth socket is reduced as much as possible, and good wrapping and fixing are ensured; the groove is smaller than a common bracket groove (0.022X0.028), so that the volume of the buccal tube is reduced, the buccal tube can be matched with a segment arch for use, and the comfort of a patient can be ensured; meanwhile, the middle part of the buccal tube is provided with a short arm and a tail end ball body, and a traction ring can be hung, so that the multipurpose is realized, and the buccal tube does not need to be frequently replaced. The mini buccal tube can be bonded tightly to the gingival margin of a molar or bicuspid tooth, can accommodate a maximum of 0.018X0.025 arch wire, or can be inserted into a free traction hook. The question mark hooks in the left direction and the right direction can be directly adhered to the gingival margin of the cuspid or the posterior tooth. The direction of the towing hook can be changed.

The utility model discloses in mini buccal surface pipe:

the two types of the grinding tooth are divided into two types, wherein the wider base plate is suitable for a first grinding tooth, and the narrower base plate is suitable for a cuspid tooth, an anterior grinding tooth and a second grinding tooth. The size is small, the arch wire can be matched with a segment arch for use (the groove can be used for placing an arch wire of 0.018X0.025), and a rubber band can be placed for traction for use, meanwhile, the bottom plate of the arch wire is attached to the shape of the neck part of a tooth body close to the gingival margin, and the short arm is positioned in the middle of the buccal tube and is not distinguished from left, right, upper and lower parts, so that the stock quantity is reduced, and the arch wire is easy to use;
