구강 내의 악골은 상악골과 하악골로 이루어지며, 상측 및 하측에 각각 상악골 및 하악골과 연결된 상부 치아 및 하부 치아가 형성되고, 턱관절 운동에 따라 상부 및 하부 치아가 서로 교합 되면서 음식물을 씹을 수 있는 구조로 이루어져 있다.The jaw in the oral cavity consists of the maxilla and mandible, and the upper and lower teeth connected to the maxilla and mandible are formed on the upper and lower sides, respectively, and the upper and lower teeth are occluded according to the motion of the jaw joint, so that food can be chewed. consist of.
일반적으로 정상인은 상악골이 하악골 보다 전방으로 더 돌출되도록 형성되어 있다. 그러나 종종 상악골이 하악골보다 작아서 상악골과 하악골이 반대로 물리는 부정 교합이 발생하는 경우가 있다.In general, in normal people, the maxilla is formed to protrude more forward than the mandible. However, the maxillary bone is often smaller than the mandible, so malocclusion occurs in which the maxillary and mandible are bitten oppositely.
상기와 같은 부정 교합이 발생하는 경우에는 상악골을 전방으로 빼냄과 아울러 상악골의 상부 치아를 확장시키는 교정 치료를 수행한다.When malocclusion as described above occurs, orthodontic treatment is performed to extend the upper teeth of the maxilla while pulling out the maxillary bone forward.
악궁 확장 장치는 상악골이 하악골에 비해 덜 발달한 부정 교합 환자의 교정 치료에 이용되는 장치로 상악골을 확장시켜 교정 치료를 용이하게 하기 위한 장치이다.The jaw extension device is a device used for orthodontic treatment of malocclusion patients whose maxillary bone is less developed than the mandible, and is a device for facilitating orthodontic treatment by expanding the maxillary bone.

Introducing the device.
이와 같은 종래 기술에 따른 악궁 확장 장치는 확장 스크루를 사용하여 본체의 간격을 확장시킴으로써 상·하악궁의 크기가 같도록 교정이 이루어지도록 한다. 상, 하악궁의 크기가 적절하게 교정된 후, 치아 면에 브라켓을 부착하여 치아교정치료를 하여 치열이 고르게 형성되도록 한다.In such a conventional arch extension device, by using an extension screw to extend the spacing of the main body, correction is made so that the sizes of the upper and lower arches are the same. After the sizes of the upper and lower arches are properly corrected, brackets are attached to the tooth surface to perform orthodontic treatment so that the teeth are evenly formed.
또한, 근래에는 공개특허 10-2015-0024245호의 미니 스크류를 이용한 악궁 확장 장치가 도 1 및 도 2에 나타낸 바와 같이 제공되었으며, 그 구성을 살펴보면 아래와 같다In addition, in recent years, as shown in Figs. 1 and 2, an arch expansion device using a mini-screw of Korean Patent Application Publication No. 10-2015-0024245 has been provided, and its configuration is as follows.

본 발명의 구개 확장장치(A)는, 도 3a 내지 도 6b에 나타낸 바와 같이 중앙에 나사 홀(11)이 형성되고, 그 나사 홀의 하부에는 납작한 가이드 홀(12)이 형성되며 후방 양측에 고정암(13)을 형성시킨 상태로 상호 마주보도록 마련된 한 쌍의 구개확장체(10); 상기 한 쌍의 구개확장체 사이에 위치하며, 중앙에 회전체(21)가 형성되고, 그 회전체의 양측에 볼트(22)를 형성시켜 된 확장스크루(20): 상기 납작한 가이드 홀에 양측이 끼워 결합 된 상태에서 상기 한 쌍의 구개확장체를 유동 없이 이동되게 하는 가이드(30); 로 이루어진다.Palate expansion device (A) of the present invention, as shown in Figures 3a to 6b, a screw hole 11 is formed in the center, a flat guide hole 12 is formed in the lower portion of the screw hole, and fixed arms on both sides of the rear A pair of palatal extensions 10 provided to face each other in a state of forming (13); An expansion screw 20 located between the pair of palatal expansion bodies and having a rotation body 21 formed in the center, and bolts 22 formed on both sides of the rotation body: both sides of the flat guide hole A guide (30) for moving the pair of palatal extension bodies without flow in a fitted state; Consists of
상기와 같은 구성의 구개 확장장치(A)에서 상기 한 쌍의 구개확장체(10)는, 좌/우 양측에 동일한 구성으로 상호 마주보게 마련되어 확장스크루(20)의 회전 방향에 따라 한 쌍의 구개확장체(10)가 좌/우 양측으로 멀어지거나 또는 좁여진다.In the palatal expansion device (A) of the configuration as described above, the pair of palatal expansion bodies 10 are provided to face each other in the same configuration on both left and right sides, and a pair of palate according to the rotation direction of the expansion screw 20 The expansion body 10 is moved away or narrowed to both the left and right sides.
이와 같이 구개확장체(10)가 좌/우 양측으로 멀어지는 것은, 도 7에 나타낸 바와 같이 상악골 또는 하악골을 확장시키기 위함이고, 그 확정되는 과정에서 납작한 가이드 홀(12)에 그 가이드 홀과 부합하는 형상의 가이드(30) 양측이 결합되기 때문에 안정적이고 견고한 이동에 따른 확장이 이루어진다.In this way, the extension of the palatal body 10 to the left and right sides is to expand the maxilla or mandible, as shown in FIG. 7, and in the process of being determined, the flat guide hole 12 coincides with the guide hole. Since both sides of the guide 30 of the shape are coupled, the expansion according to the stable and solid movement is made.
그리고 상기 구개확장체(10)의 후방 양측에는 고정암(13)이 설치되는데, 그 고정암(13)은, 구개확장체(10)의 위치를 조정한 후 치아에 걸어 고정하는 것으로, 상기 치아에는 고정암(13)의 단부를 걸어 고정할 수 있는 고정부재(도면 미도시)가 설치된다.In addition, there are fixed arms 13 installed on both rear sides of the palatal expansion body 10, and the fixing arms 13 are fixed to the teeth after adjusting the position of the palatal expansion body 10, and the teeth A fixing member (not shown) capable of fastening the end of the fixing arm 13 is installed.
종래에는 도 1 및 도 2에 나타낸 바와 같이 가이드가 원형의 축 형태로 형성되기 때문에 구개확장체가 유동할 수 있는 단점이 있고, 또 확장 후 구강 내에 고정한 상태에서 다양한 각도에서 힘이 발생하기 때문에 그에 따른 구개확장체가 유동 되어 악골의 확장이 정교하게 이루어지지 못하는 문제점이 발생할 수 있으며, 그와 아울러 원형의 축이 2개 설치되는 문제점이 있다.Conventionally, as shown in Figs. 1 and 2, since the guide is formed in a circular shaft shape, there is a disadvantage in that the palatal extension body can flow, and since the force is generated at various angles while being fixed in the oral cavity after expansion, There may be a problem that the extension of the jaw cannot be elaborated due to the movement of the palatal extension, and there is a problem in that two circular shafts are installed.
그러나 본 발명에서는 가이드 홀(12)을 납작하게 형성시키고 그 가이드 홀(12)에 결합되는 가이드(30)의 양측도 상기 가이드 홀(12)과 부합하며 긴밀하게 결합 되도록 납작하게 형성시킴으로써 상기 종래의 문제점을 해결할 수 있는 장점이 있는 것이다.However, in the present invention, the guide hole 12 is formed flat, and both sides of the guide 30 coupled to the guide hole 12 are formed flat to match the guide hole 12 and closely coupled. There is an advantage that can solve the problem.
또한, 상기 구개확장체(10)를 확장시키는 것은, 확장스크루(20)의 회전과 함께 이루어지고, 상기 확장스크루(20)는, 상기 한 쌍의 구개확장체 사이에 위치하며 중앙에 회전체(21)가 형성되고, 그 회전체(21)의 양측에 볼트(22)가 형성되어 그 양측의 볼트(22)가 상기 각각의 나사 홀(11)에 나사 결합된다.In addition, expanding the palatal expansion body 10 is made with the rotation of the expansion screw 20, and the expansion screw 20 is located between the pair of palatal expansion bodies and is a rotating body ( 21) is formed, and bolts 22 are formed on both sides of the rotating body 21 so that the bolts 22 on both sides thereof are screwed into the respective screw holes 11.
한편, 상기 회전체(21)의 일실시 예 구성은, 외주 면을 따라 적어도 5개 이상의 평면부(21a)가 상호 연이어지게 형성된 다각형으로 이루어지고, 상기 일 측의 볼트(22) 선단에는 공구결합부(22a)를 형성시켜 사용할 수 있다.On the other hand, the configuration of an embodiment of the rotating body 21 is made of a polygon formed so that at least five or more flat portions 21a are connected to each other along the outer circumferential surface, and a tool coupling at the tip of the bolt 22 on one side It can be used by forming the part 22a.
상기 회전체(21)를 5개 이상의 평면부(21a)가 상호 연이어지게 형성된 다각형으로 형성시키는 이유는, 구개확장체(10)를 확장완료 후 스토퍼(40)가 상기 평면부(21a)를 지지하여 확장스크루(20)의 회전을 제어하기 위함이다.The reason for forming the rotating body 21 in a polygonal shape in which five or more flat portions 21a are connected to each other is, the stopper 40 supports the flat portion 21a after the palatal extension 10 is expanded. This is to control the rotation of the expansion screw (20).
상기 구개확장체(10)는, 확장 후 고정한 상태에서 다양한 각도로 힘이 가해지기 때문에 그에 따른 상기 확장스크루(20)가 회전하여 구개확장체(10)가 고정 위치로부터 이동하여 구개확장이 목적하는 바와 다를 수 있음으로 상기 스토퍼(40)가 확장스크루(20)를 지지하며 견고하게 고정시켜 주어 구개확장체(10)의 견고한 지지를 유지해 준다.Since the palatal expansion body 10 is fixed after expansion, the force is applied at various angles, so that the expansion screw 20 rotates to move the palatal expansion body 10 from the fixed position, so that the palatal expansion is desired. As it may be different from that, the stopper 40 supports the expansion screw 20 and securely fixes it to maintain the firm support of the palatal expansion body 10.
