Description

Technical Field

[0001] The utility model relates to the field of medical appliances, and particularly relates to a three-hole physiological anchorage buccal tube for orthodontics. Background Art

[0002] An orthodontic device is an indispensable force-applying unit for realizing tooth movement in orthodontic technology. Common orthodontic devices include brackets, buccal tubes, main arch wires, etc. Among them, brackets and buccal tubes belong to fixed devices and can be fixed to the tooth surface through their bottom plates or bands close to the tooth surface. The main arch wire conducts the deformation force of the arch force to the teeth by actively or passively ligating to the brackets and passing through the pre-reserved grooves in the buccal tube, so as to achieve the purpose of controlling tooth movement or stabilizing the target teeth.

[0003] Among them, the buccal tube is a commonly used auxiliary part in orthodontic treatment, generally composed of a bottom plate, a tube body and a traction hook. The bottom plate is bonded and assembled on the surface of the posterior tooth crown for use, mainly used for fixing the orthodontic wire; the traction hook can be used to hang rubber bands, etc. for intra-arch or inter-arch traction, and transmit the orthodontic force to the teeth. The existing buccal tubes are generally single-tube buccal tubes and double-tube buccal tubes. The single-tube buccal tube can only use a single arch wire and cannot use an auxiliary arch wire; the double-tube buccal tubes are parallel, and two arch wires can be used. The main arch wire and the auxiliary arch wire cooperate to achieve the alignment of the entire dentition.

[0004] When the double-tube buccal tube is used for orthodontics, if the second molar has not erupted, the retraction of the anterior teeth will cause insufficient anchorage of the posterior teeth, resulting in the forward inclination of the posterior teeth and unable to obtain the expected orthodontic effect. For example, a double-tube buccal tube with the authorization announcement number of CN 217488906 U is provided with a main tube and an auxiliary tube to realize the simultaneous use of the main arch wire and the auxiliary arch wire, but it cannot resist the reaction force during the retraction of the anterior teeth and is prone to cause the forward inclination of the posterior teeth. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a three-hole physiological anchorage buccal tube, which can protect the anchorage of the posterior teeth, resist the reaction force during the retraction of the anterior teeth, and thus ensure the orthodontic effect.

[0006] To achieve the above purpose, the utility model proposes the following technical solutions:

[0007] A three-hole physiological anchorage buccal tube includes a bottom plate and a tube body, and the tube body is arranged on the bottom plate; the bottom surface of the bottom plate is an arc surface adapted to the outer wall of the tooth, and a rough surface is arranged on the bottom surface of the bottom plate.

[0008] Three through holes are arranged in the tube body, namely a main arch tube, a secondary arch tube and an auxiliary arch tube. The main arch tube and the secondary arch tube are thick wire holes, and the auxiliary arch tube is a thin wire hole.

[0009] The main arch tube is arranged along the length direction of the tube body. One end of the main arch tube is the arch wire inlet, and the other end is the arch wire outlet, namely the first arch wire outlet. The auxiliary arch tube is arranged in front of the main arch tube. The center line of the auxiliary arch tube intersects with the center line of the main arch tube, and the included angle between the center line of the auxiliary arch tube and the center line of the main arch tube is 10° to 45°. The arch wire outlet of the auxiliary arch tube is opened on the front side of the tube body. The arch wire outlet of the auxiliary arch tube is the second arch wire outlet. The auxiliary arch tube and the main arch tube share one arch wire inlet. The auxiliary arch tube is arranged behind the main arch tube, and the center line of the auxiliary arch tube is parallel to the center line of the main arch tube.

[0010] A traction hook is arranged on the rear side of the tube body. The traction hook includes a connecting body and a main hook body. The included angle between the main hook body and the connecting body is 80° to 100°. The main hook body is connected to the tube body through the connecting body. The main hook body extends along the length direction of the tube body and faces the first arch wire outlet.

[0011] Preferably, a concave surface is arranged on the edge of the bottom plate. The concave surface is placed on the front side of the tube body. The concave surface is located at the middle position of the edge of the bottom plate. The concave surface is adapted to the concave part on the surface of the tooth crown, so that the buccal tube can better fit the tooth and better protect the posterior tooth anchorage.

[0012] Preferably, the main arch tube is a square hole, and the inner bottom surface of the main arch tube is an inclined surface, with the rear side lower than the front side.

[0013] Preferably, the auxiliary arch tube is a square hole, and the included angle between the center line of the auxiliary arch tube and the center line of the main arch tube is 20° to 35°.

[0014] Preferably, the included angle between the main hook body and the connecting body is 90°.

[0015] Preferably, a spherical object is arranged at the end of the main hook body of the traction hook. The diameter of the spherical object is not less than the diameter of the end of the main hook body, reducing the abrasion to the patient's oral cavity.

[0016] Preferably, the traction hook is arranged on the side wall at the rear side of the tube body.

[0017] Specifically, when orthodontic treatment is carried out, the main arch wire and the auxiliary arch wire pass through the main arch tube and the auxiliary arch tube respectively, helping to open the bite and align the teeth at the same time. When the bite is opened, the space is closed, and differential force can be used to adjust the occlusal relationship during closing. Then, fine adjustment is carried out, and the occlusal adjustment, midline adjustment, and torque expression are carried out by using a stainless steel arch wire or an arch wire of other materials. After this stage is completed, the retention stage can be entered.

[0018] Before the second molar erupts, full bonding of 6-6 means bonding brackets to all six anterior teeth in both the upper and lower jaws, bonding buccal tubes to the 6th teeth, and passing the arch wire through the brackets and the auxiliary arch tubes of the buccal tubes, which can serve as physiological anchorage to counteract the reaction force during the retraction of the anterior teeth; when it is necessary to intrude the anterior teeth to solve deep overbite, bond 3-3 and 6, that is, bond brackets to three anterior teeth in both the upper and lower jaws, bond buccal tubes to the 6th teeth, and pass the arch wire through the brackets and the auxiliary arch tubes of the buccal tubes to achieve a reverse curve, thereby helping to intrude the anterior teeth and open the bite.

[0019] The beneficial effects of the present utility model are as follows:

[0020] By providing a main arch tube, an auxiliary arch tube and an auxiliary arch tube, and cooperating for orthodontic treatment of teeth, the present utility model can help open the bite of the anterior teeth, and at the same time protect the posterior tooth anchorage during the retraction of the anterior teeth, further ensuring the orthodontic effect.

[0021] By providing a concave surface on the bottom surface of the base plate, which is adapted to the concave part of the tooth, the buccal tube can better fit the tooth, better protecting the posterior tooth anchorage.

[0022] Adopting the above solution, the present utility model can protect the posterior tooth anchorage, resist the reaction force during the retraction of the anterior teeth, and thus ensure the orthodontic effect. Description of the Drawings
