Abstract

The present invention allows an orthodontic bracket to be manufactured so that a sufficient orthodontic force of an orthodontic wire can be transferred to the teeth of a subject, and in a base structure conforming to the teeth of the subject if necessary, even when the bracket is manufactured using a synthetic resin material not by conventional methods such as sinter-molding or a cutting process, but by other methods, thereby minimizing a feeling of irritation. As a means for achieving the objective, the present invention allows an orthodontic bracket to be manufactured using a synthetic resin having biocompatibility by a printing method of laminating a layer of a base and a layer of head constituting the bracket using a 3D printing technique, wherein two-stage orthodontic wires are installed and used by providing double slots on the head so that the orthodontic force applied to each slot is halved whereby no problem occurs in use.

Description

3D프린터기를 이용한 이중슬롯형 치열교정용 브라켓Double slot orthodontic bracket using 3D printer
본 발명은 치열교정용 브라켓에 관한 것으로서, 특히 3D프린터기를 이용하여 생체적합성을 갖는 합성수지로 브라켓을 제작하되, 헤드에 구성되는 슬롯을 이중으로 구성하여 합성수지로 브라켓을 구성하더라도, 파손되는 현상없이 교정용 와이어를 이용한 교정력이 치아에 원만하게 전달될 수 있게 한 것이다.The present invention relates to orthodontic brackets, in particular, the bracket is made of synthetic resin having biocompatibility using a 3D printer, even if the bracket is composed of a synthetic resin by constituting a double slot configured in the head, correction without damage Orthodontic force using the dragon wire to be able to be transmitted smoothly to the teeth.
일반적으로 치열의 교정이란 부정치열을 바르게 시술하는 것으로서, 접착제로 각 치아의 표면에 브라켓을 고정하고, 교정용 와이어를 다수의 브라켓에 연결하고, 상기 와이어의 탄성 또는 복원력을 이용하여 치아에 교정력이 부여되게 함으로서 틀어진 치아를 서서히 이동시켜 바르게 정열하는 것이다.In general, the orthodontic treatment is an incorrect dental treatment. The bracket is fixed to the surface of each tooth with an adhesive, the orthodontic wire is connected to a plurality of brackets, and the orthodontic force is applied to the tooth using the elasticity or the restoring force of the wire. By allowing them to be imparted, the wrong teeth are moved slowly to align them correctly.
상기에서 치아에 부착되어 교정력을 전달하는 브라켓의 제조는 주로 절삭가공기로 금속을 절삭하는 절삭가공방법이나, 성형틀에 성형물을 주입하여 소결하는 방법으로 브라켓을 제작하였다.In the manufacturing of the bracket to be attached to the teeth to transmit the corrective force is mainly produced by cutting the cutting method of cutting metal with a cutting machine, or by inserting the molding into the molding die and sintering.
따라서 상기한 브라켓의 경우 소재 자체가 금속 혹은 소결성형된 세라믹과 같은 재질로서 강성이 매우 강하기 때문에 단일슬롯에 교정용 와이어를 끼운 다음 틀어진 치아의 교정을 위한 교정력이 브라켓에 인가되게 하더라도 충분한 내력을 가지기 때문에 사용하는 문제가 발생하지 않는다.Therefore, in the case of the bracket, since the material itself is a material such as a metal or sintered ceramic, the stiffness is very strong. Because of this problem does not occur.
최근들어 3D프린팅 기술을 이용한 제품의 제조가 다양한 형태로 시도되고 있으며, 의료분야에서도 한정적인 범위내에서 일부 시도되고 있다.Recently, manufacturing of products using 3D printing technology has been attempted in various forms, and in the medical field, some attempts have been made within a limited range.
3D프린팅 기술을 이용하여 치열교정용 브라켓을 제작사용할 수도 있겠으나, 종래와 같이 헤드에 구성되는 슬롯이 단일구성일 경우 틀어진 치아에 교정력을 전달하기 위하여 각형으로 된 와이어를 슬롯에 끼운 다음 교정력이 인가되게 하면 수지로 된 브라켓의 헤드가 와이어의 탄성이나 복원력을 지탱하지 못하고 파손되므로 사실상 사용이 불가능하였다.Orthodontic brackets can be manufactured and used using 3D printing technology. However, if the slots in the head have a single configuration as in the prior art, a square wire is inserted into the slots to deliver orthodontic force to the distorted teeth, and then the orthodontic force is applied. In this case, the head of the resin bracket was broken because it could not support the elasticity or the restoring force of the wire, and thus was practically impossible to use.

본 발명은 3D프린팅을 통하여 브라켓(10)을 제작하되 생체적합성을 갖는 열가소성 수지로 제작하게 되므로 절개부(31)를 갖는 탄지형 슬롯의 제작이 가능하게 될 뿐 아니라, 탄지형 슬롯에 교정용 와이어(60)를 결합할때에서 절개부(31)를 구성하는 탄지편(32)이 적절한 탄성으로 확개되므로 와이어의 결합이 가능하게 된다.In the present invention, the bracket 10 is manufactured through 3D printing, but is made of a thermoplastic resin having biocompatibility, so that not only the production of the hardened slot having the cutout portion 31 is possible, but also the wire for correction in the hardened slot. When engaging the 60, the finger piece 32 constituting the cutout portion 31 is expanded to an appropriate elasticity, so that the coupling of the wires is possible.
특히 본 발명에는 3D프린터를 이용하여 브라켓(10)을 제작하되, 피시술자의 치아에 맞는 맞춤형 브라켓(10)을 직접 제작사용할 수 있다.Particularly, in the present invention, the bracket 10 is manufactured using the 3D printer, but the customized bracket 10 suitable for the tooth of the subject can be manufactured and used directly.
즉 교정하고자 하는 피시술자의 치아부분을 3D스캐너를 이용하여 피시술자의 치아 각각의 구조 데이터를 확보하고, 확보된 치아구조 데이터를 그림파일로 변환시킨다.That is, the tooth part of the subject to be corrected by using a 3D scanner to secure the structural data of each of the subject's teeth, and converts the obtained tooth structure data into a picture file.
그림파일로 변환시킨 상태에서 브라켓(10)이 부착되는 치아(70)의 외형을 본뜬 다음 본떠진 형상에 헤드(30)을 붙여 3D도면을 작성하고, 이를 컴퓨터에 정해진 데이터양식으로 입력하고, 입력된 데이터를 3D프린터로 프린팅하면 도 3 내지 도 6에서와 같이 베이스(20)의 접촉면(21)이 피시술자의 치아(70) 외형과 일치되는 형태로 제작된다.After converting to a picture file, the shape of the tooth 70 to which the bracket 10 is attached is modeled, and then the 3D drawing is created by attaching the head 30 to the distal shape, and inputting the data in a predetermined data form on a computer. When the printed data is printed on the 3D printer, as shown in FIGS. 3 to 6, the contact surface 21 of the base 20 is manufactured to match the appearance of the tooth 70 of the subject.
이상에서 설명한 바와 같이 본 발명은 인체적합성을 갖는 열가소성 합성수지를 이용하여 3D프린팅장치로 브라켓(10)을 제작하되, 헤드(30)에 구성되는 슬롯을 헤드(30) 중심을 기준으로 양측에 제1슬롯(40)과 제2슬롯(50)이 나란히 이중구성되게 함으로서, 슬롯에 끼워지는 교정용 와이어(60)를 이중설치하여 필요한 교정력을 1/2로 분산시킬 수 있게 되므로 3D프린터로 제작된 합성수지 브라켓의 경우에도 교정력을 충분히 지탱할 수 있게 된다.As described above, in the present invention, the bracket 10 is manufactured by the 3D printing apparatus using the thermoplastic synthetic resin having human body compatibility, and the slots of the head 30 are firstly formed on both sides of the head 30. Since the slot 40 and the second slot 50 are configured to be duplex side by side, by double-installing the calibration wire 60 to be inserted into the slot, it is possible to disperse the required calibration force in half, so that the synthetic resin produced by the 3D printer In the case of brackets, it is possible to fully support the corrective force.
뿐만 아니라 필요한 경우 도 1 내지 도 4의 제2슬롯(50)과 같이 절개부(31)가 형성된 탄지형 슬롯으로 제작할 수 있고, 슬롯에 교정용 와이어(60)를 끼우고자 절개부(31)에 밀어넣으면 탄지편(32)이 확장되면서 절개부(31)를 통하여 와이어(60)가 제2슬롯(50)에 간단하게 끼워지게 되고, 와이어(60)가 끼워지면 탄지편(32)은 원복하여 절개부(31)가 다시 좁아지게 되므로 와이어(60)의 이탈이 방지된다.In addition, if necessary, as shown in the second slot 50 of FIGS. 1 to 4, the cutout part 31 may be manufactured as a cardiac slot in which the cutout part is formed, and the cutout part 31 to insert the calibration wire 60 into the slot. When it is pushed in, the bombardment piece 32 is expanded and the wire 60 is simply inserted into the second slot 50 through the cutout 31. When the wire 60 is fitted, the burnt piece 32 is rolled back. As the cutout 31 is narrowed again, the separation of the wire 60 is prevented.
또한 제1,2슬롯(40)(50)은 헤드(30) 중심부를 기준으로 양측에 나란히 구성되어 있고, 상기 제1,2슬롯(40)(50)에 와이어(60)가 이중설치되어 적절한 교정력을 부여하게 되므로 원형와이어(60)로도 틀어진 치아(70)에 교정력을 전가할 수 있게 된다.In addition, the first and second slots 40 and 50 are configured side by side on both sides of the center of the head 30, and the wires 60 are doublely installed in the first and second slots 40 and 50 so as to be appropriate. Since the orthodontic force is given, the orthodontic force can be transferred to the distorted tooth 70 even with the circular wire 60.
제1슬롯(40)과 같은 개방형 슬롯에는 원형와이어나 사각와이어를 선택사용할 수도 있다.An open slot such as the first slot 40 may be used by selecting a circular wire or a square wire.
또한 베이스(20)의 접촉면(21)을 피시술자의 치아(70) 표면형상과 동일하게 제작하여 브라켓(10) 부착시 이물감을 최소화할 수 있을 뿐 아니라 견고한 접착성을 기대할 수 있다.In addition, by making the contact surface 21 of the base 20 to be the same as the surface shape of the tooth 70 of the subject, it is possible to minimize the foreign matter when the bracket 10 is attached, as well as to expect a firm adhesiveness.
본 발명에서 제공하고자 하는 치열교정용 브라켓(10)은 치아(70)의 내외측, 즉 설측과 순측 모두 적용가능하다. Orthodontic bracket 10 to be provided in the present invention is applicable to both the inner and outer sides, that is, lingual and labial side of the tooth (70).
