Typically, the bracket for orthodontics of the tooth 12 is a method of detaching the orthodontic wire 20 in front and rear, and should use the ligation wire or rubber for close support. While the bracket of the present invention is configured to exclude the use of ligation wire or rubber. In the following description, directions such as 'front and rear', 'upper', and 'lower' are divided based on a state in which the bracket is attached to the tooth 12.
한편, 교정와이어(20)는 자체적으로 탄성을 지니는 금속선으로서 바람직하게는 형상기억합금을 사용하는 것이 좋다. 교정와이어(20)는 상ㆍ하악에 대응하도록 만곡을 지닌다.On the other hand, the straightening wire 20 is preferably used as a metal wire having its own elastic shape memory alloy. The straightening wire 20 has a curve so as to correspond to the upper and lower jaw.
본 발명은 크게 A형브래킷(21)과 B형브래킷(22)으로 구분되는 조합으로 이루어진다. A형브래킷(21)은 상기 교정와이어(20)의 지지를 위한 슬롯(30)의 토크가 하향각(41)으로 형성되고, B형브래킷(22)은 상기 교정와이어(20)의 지지를 위한 슬롯(30)의 토크가 상향각(42)으로 형성되는 구조이다.The present invention consists of a combination largely divided into the A-type bracket 21 and the B-type bracket (22). The A-type bracket 21 has a torque of the slot 30 for supporting the calibration wire 20 at a downward angle 41, and the B-type bracket 22 is used for supporting the calibration wire 20. The torque of the slot 30 is a structure formed at an upward angle 42.
A형브래킷(21)와 B형브래킷(22)은 공히 치아(12)에 접합되는 베이스(23)를 구비하고, 베이스(23)는 성인 치아(12)의 평균적인 곡면으로 형성된다. 베이스(23)에서 연장되는 4개의 면을 '측면'이라 하고, 베이스(23)와 평행하게 형성되어 노출되는 면을 '전면'이라 한다. A형브래킷(21)과 B형브래킷(22)의 구분은 후술하는 것처럼 치아(12)의 토크각과 연계되는 것으로 베이스(23)에 대한 슬롯(30)의 자세로 구분되고 시술된다. 슬롯(30)은 교정와이어(20)가 안착되어 탄성력을 작용하는 부분으로서 치수가 정형화된다.The A-type bracket 21 and the B-type bracket 22 have a base 23 joined to the tooth 12, and the base 23 is formed with an average curved surface of the adult tooth 12. Four surfaces extending from the base 23 are referred to as 'sides', and a surface formed in parallel with the base 23 and exposed is referred to as a 'front'. The A-type bracket 21 and the B-type bracket 22 is divided into the posture of the slot 30 with respect to the base 23 to be associated with the torque angle of the tooth 12 as described below. The slot 30 is dimensioned as a portion on which the straightening wire 20 rests and exerts an elastic force.

It is preferable that the round dimension is formed to be at least 0.1 mm, but when it exceeds 1.0 mm, the mounting of the calibration wire 20 becomes unstable. The introduction groove 32 is formed to have a round while the entrance is wider to facilitate the entry and exit of the calibration wire 20.
본 발명의 세부 구성에 의하면, 상기 A형브래킷(21)의 하향각(41)은 슬롯(30)의 외단에서 내단으로 접근할수록 베이스(23)와의 높이가 동일 또는 축소되도록 형성되는 것을 특징으로 한다. 하향각(41)은 A형브래킷(21)의 베이스(23)를 수평면에 놓을 때 도입홈(32)의 형태에 관계없이 교정와이어(20)가 슬롯(30)에 안착되는 자세로 결정한다. 즉, 슬롯(30)의 중심선이 내단으로 갈수록 베이스(23)와의 거리가 축소되어 하향각(41)을 형성한다.According to the detailed configuration of the present invention, the downward angle 41 of the A-shaped bracket 21 is characterized in that the height with the base 23 is the same or reduced as the inner end approaches the outer end of the slot (30) . The downward angle 41 determines the posture of the straightening wire 20 seated in the slot 30 regardless of the shape of the introduction groove 32 when the base 23 of the A-type bracket 21 is placed on the horizontal plane. That is, the distance from the base 23 is reduced as the center line of the slot 30 toward the inner end forms a downward angle 41.
상기 B형브래킷(22)의 상향각(42)은 슬롯(30)의 외단에서 내단으로 접근할수록 베이스(23)와의 높이가 동일 또는 증가되도록 형성한다. B형브래킷(22)의 상향각(42)은 전술한 A형브래킷(21)의 하향각(41)과 반대되는 형태이다. 즉, 슬롯(30)의 중심선이 내단으로 갈수록 베이스(23)와의 거리가 증가되어 상향각(42)을 형성한다.The upward angle 42 of the B-shaped bracket 22 is formed so that the height with the base 23 is the same or increased as the inner end approaches the inner end of the slot 30. The upward angle 42 of the B type bracket 22 is opposite to the downward angle 41 of the A type bracket 21 described above. That is, the distance from the base 23 increases as the center line of the slot 30 goes to the inner end, thereby forming the upward angle 42.
