Description

An easily adjustable titanium plate implant

technical field

The utility model relates to a medical device, in particular to an easily adjustable titanium plate implant.

Background technique

The so-called anchorage is the reaction force unit or anatomical structure that resists the orthodontic force acting on the teeth. Whether the orthodontic tooth can move in the direction and degree required by the design has an important relationship with the design of the anchorage part. The emergence of implant anchorage provides a basis for the treatment of various difficult cases. The implant anchorage represented by micro-screws utilizes the biocompatibility of titanium to be implanted in the alveolar bone and fuse with the bone tissue to bear the correction force. However, microscrews loosen or even fall off repeatedly in clinical work, which affects the treatment effect, brings psychological pressure to patients, and easily causes conflicts between doctors and patients. The reasons may be analyzed in the following aspects: ①During the operation, due to the limitation of the oral environment, the angle of the screw implanted into the bone surface and the direction of the force are greater than 90 degrees. When the force is applied for a long time, its stability will gradually weaken; ②In the area with more cancellous bone, if the screw depth is not enough, its retention is poor. If the traction force is too large, the anchorage screw is easy to loosen and fall off; ③During the anchorage screw implantation process, the rotation handle swings too much, resulting The adhesion between the screw and the bone is not good, and the screw is easy to loosen during the traction process. With the help of the characteristics of the titanium plate itself and the biocompatibility with soft and hard tissues in the solid internal fixation technology, the implanted titanium plate uses two screws to fix a section of the titanium plate on the jawbone to increase the anchorage during orthodontics. At present, most of the titanium plate implants used clinically are simply modified titanium plates used for jaw fracture fixation, which is not conducive to adjusting the direction of traction. It is difficult to operate when hanging rubber rings or steel wires, and the comfort is poor. Patients have obvious foreign body sensation. And easy to damage the oral mucosa.

Utility model content

The utility model mainly aims at the problems existing in the current technology, and provides a titanium plate implant with simple structure, easy adjustment of traction direction and angle, good patient comfort, low interference and high stability.

The technical problem of the utility model is mainly solved by the following technical solutions:

An easy-to-adjust titanium plate implant, the titanium plate implant is Y-shaped, and includes a V-shaped retainer, a connecting bridge, and a force-receiving body connected in sequence from top to bottom; the retainer is provided with three screw holes for retention, the screw holes for retention are distributed in an isosceles inverted triangle, and the included angle of the apex angle is 80 degrees; four c-shaped holes are sequentially arranged at the edge of the force receiving body and longitudinally, and the corresponding The opening directions of the two adjacent c-shaped holes are opposite.

As a preferred item: the width at the two branch ends of the retainer is 3.0 mm; the diameter of the screw hole for the retention is 2 mm; the waist length of the isosceles triangle formed by the center connection of the three retention screw holes 7mm.

As a preferred item: the connecting bridge is 10mm long, 1.5mm wide, and 0.6mm thick.

As a preferred item: the force-receiving body is 10mm long and 1.5mm wide, and the diameter of the c-shaped hole on it is 1.0mm.

In the utility model, the stressed part is exposed in the oral cavity, the width and thickness of the titanium plate are reduced, and four bidirectional continuous embedded C-shaped rings are designed, which are convenient for hanging rubber rings or ligature wires according to the direction and angle of traction, and at the same time reduce metal The discomfort of foreign bodies in the oral cavity reduces the chance of oral mucosal damage; due to the different directions of the C-shaped holes, it is suitable for traction in various situations, and can satisfy the traction of the upper and lower jaws on the left and right sides. It is easy to operate and has high stability.

detailed description

In order to facilitate those of ordinary skill in the art to understand and implement the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the utility model, and It is not used to limit the utility model.

Please see Figure 1. This embodiment provides an easily adjustable titanium plate implant. The titanium plate implant is Y-shaped and includes a V-shaped retainer 1, a connecting bridge 2, and a force-bearing body connected in sequence from top to bottom. 3. The retainer 1 is provided with three retaining screw holes 4, the retaining screw holes 4 are distributed in an isosceles inverted triangle, and the included angle of the top angle is 80 degrees; the edge of the force receiving body 3 is provided with 4 longitudinally in sequence. Two c-shaped holes 5, the opening directions of the two adjacent c-shaped holes 5 are opposite, easy to adjust the traction direction and angle, and convenient to hang rubber bands or ligature wires, while reducing the chance of oral mucosal damage.

The width at the two branch ends of the retainer 1 described in this embodiment is 3.0 mm; the diameter of the screw hole 4 for retention is 2 mm; 7mm in length; the connecting bridge 2 is 10mm in length, 1.5mm in width, and 0.6mm in thickness; The width and thickness of the titanium plate at the site are reduced, reducing the discomfort of metal foreign bodies in the oral cavity.

The fixed part of the utility model is designed as 3 holes. According to clinical needs, under local anesthesia, the mucous periosteum and flap are cut in the buccal posterior root tip area of the upper or mandible to expose the cortical bone. The direction is adjusted and fixed with screws. The part of the stressed body is exposed in the oral cavity, and it is convenient to hang a rubber ring or a ligature wire on the C-shaped hole according to the direction and angle of the traction. After the orthodontic treatment, it is taken out under local anesthesia.

Although this specification often uses terms such as retainer 1, connecting bridge 2, force receiving body 3, screw hole 4 for retaining, and c-shaped hole 5, the possibility of using other terms is not excluded. These terms are only used to describe the essence of the utility model more conveniently, and they are interpreted as any kind of additional limitation and all violate the spirit of the utility model.

It should be understood that the parts not described in detail in this specification belong to the prior art.
