A : 상악동 거상술을 위한 임플란트 드릴A: implant drill for maxillary sinus elevation

본 발명은 치과용 임플란트 드릴에 관한 것으로, 더욱 상세하게는 상악동내막의 손상 없이 손쉽고 간편하게 상악골을 천공할 수 있어 상악동 거상을 용이하게 술식할 수 있도록 하는 상악동 거상술을 위한 임플란트 드릴에 관한 것이다.The present invention relates to a dental implant drill, and more particularly, to an implant drill for maxillary sinus elevation that can easily perforate the maxillary bone without damaging the maxillary sinus lining.

최근 치과에서는 인공치아를 식립하는 임플란트 술식이 빠르게 보급되고 있다.In recent years, dental implants are rapidly being used to implant artificial teeth.

그러나, 환자 중 상당수는 임플란트를 시술하기 힘든 구강 구조를 갖고 있어 시술에 곤란함을 겪게 되며, 일부 의사들은 이러한 환자를 기피하게 된다However, many of the patients have oral structures that are difficult to implant, making it difficult for some patients to avoid such patients.

특히, 상악동이 위치한 구치부에서의 잔존골이 부족하여 임플란트를 식립하기 곤란한 경우에 많은 어려움을 겪게 되는데,In particular, it is difficult to implant the implant because of the lack of residual bone in the posterior region where the maxillary sinus is located.

이와 같은 경우 상악동내막을 거상시켜 공간을 형성한 후 확보된 공간에 골 이식을 하고 여기에 임플란트를 매식하는 방법을 이용하게 되며, 이는 수직접근법과 측방접근법 두 가지로 구분된다.In this case, after forming a space by elevating the maxillary sinus, the bone graft is implanted in the secured space and implanted therein, which is divided into two types of vertical approach and lateral approach.

먼저, 수직접근법은 임플란트 시술부위에 잔존골이 어느 정도 확보되었을 때(잔존골의 두께 4mm 이상)의 방법으로, 상악동내막에 손상이 발생하지 않도록 오스테오톰(끌과 망치) 이라는 기구로 상악골을 여러 횟수 두드려 직경 2~3mm의 구멍을 낸 다음 구멍을 통해 이식골을 조금씩 넣는 방식이며, First of all, the vertical approach is when the remaining bone is secured to the implant site (more than 4mm thick), so that the maxillary bone is broken by a mechanism called osteotomies (chisel and hammer) to prevent damage to the maxillary sinus. Tap the number of times to make a hole with a diameter of 2-3mm, and then insert the graft little by little through the hole.

이는 시술부위가 좁아 시술 후 환자에게서 부종 발생이 적은 장점이 있으나, 시술과정에서 상악동내막을 직접 볼 수 없기 때문에 그 과정을 엑스레이로 확인하면서 아주 조심스럽게 작업을 진행하게 되므로 시술 시간이 오래 소요되고, 시술과정에서의 타격으로 인해 환자에게 상당한 불쾌감이 따르게 되는 문제가 있었다.This has the advantage that the swelling occurs less frequently in the patient after the procedure because of the narrow surgical site, but because the maxillary sinus lining cannot be seen directly during the procedure, the procedure takes a long time because the procedure is performed very carefully while checking the process by X-ray. Due to the blow in the procedure there was a problem that the patient is accompanied by a significant discomfort.

다음으로, 측방접근법은 임플란트 시술부위의 잔존골이 매우 부족할 때(잔존골의 두께 4mm 이하)의 방법으로, 상악동의 측면에 구멍(윈도우)을 형성하여 상악동내막을 거상시킨 후 이를 통해 골 이식을 하는 방식이며,Next, the lateral approach is a method when the remaining bone of the implant site is very lacking (less than 4mm thickness of the remaining bone). A hole (window) is formed on the side of the maxillary sinus to elevate the maxillary sinus lining, and then bone graft is performed. Way,

이는 시술중에 상악동내막을 직접 보면서 들어올릴 수 있어서 상악동내막에 손상이 발생하는 경우가 적을 뿐 아니라 혹 손상이 발생한다 하더라도 후처리가 가능하고, 한꺼번에 원하는 양의 골이식재를 빨리 넣을 수가 있어서 신속한 진행이 가능한 장점이 있으나,It can be lifted up while looking directly at the maxillary sinus lining during the procedure, which means less damage to the maxillary sinus lining, and even post-treatment is possible even if damage occurs. There are possible advantages,

수술 자체가 어렵고 커다란 판막을 형성해야 하기에 수술후 심한 부종이 발생하는 문제가 있어 이러한 술식을 기피하고 있는 실정이다.Because the surgery itself is difficult and a large valve to form a severe edema occurs after the operation is avoiding this operation.

한편, 최근에는 상기의 방법과 더불어 도 4에 도시되어진 바와 같은 일반 임플란트용 드릴을 이용한 상악동 거상술이 연구되고 있는데,Meanwhile, recently, maxillary sinus elevation using a general implant drill as shown in FIG. 4 along with the above method has been studied.

임플란트용 드릴에 의한 술식은 환자의 거부감이 적고, 쉽고 빠른 시간에 상악골 천공이 가능한 장점은 있을 수 있으나, 드릴날 회전에 의해 상악골 천공이 완료되는 순간 드릴날 선단이 상악동내막과 접촉하는 것을 차단할 만한 수단이 마련되어 있지 않으므로 상악동내막이 드릴날 선단에 의해 찢기거나 말려드는 현상을 피할 수 없어 상악동내막에 손상이 발생하기 때문에 현재로서는 드릴을 이용한 상악동 거상술은 거의 불가능한 상태라 할 수 있다.The procedure of the implant drill may be advantageous in that the patient's discomfort is low and the maxillary perforation can be performed easily and quickly. However, the tip of the drill blade may block the contact with the maxillary sinus lining when the perforated maxillary perforation is completed by rotating the drill blade. Since no means is provided, the maxillary sinus lining is incapable of being torn or curled by the tip of the drill blade, resulting in damage to the maxillary sinus lining.

본 발명은 상기와 같은 실정을 감안하여 안출한 것으로, 상악동내막의 손상 없이 손쉽고 간편하게 상악골을 천공할 수 있어 상악동 거상술을 용이하게 진행할 수 있도록 하는 상악동 거상술을 위한 임플란트 드릴을 제공하는데 그 목적이 있는 것이다.The present invention has been made in view of the above situation, and it is an object of the present invention to provide an implant drill for maxillary sinus elevation to facilitate the maxillary sinus elevation by easily and simply puncturing the maxillary bone without damaging the maxillary sinus lining. .

상기의 목적을 달성하기 위한 본 발명의 상악동 거상술을 위한 임플란트 드릴은, 원통형 몸체 외주면에 컷팅홈이 형성되고 생크부를 구비한 중심축이 마련되어 치과용 일반 핸드피스에 장착되는 임플란트 드릴에 있어서, 상기 몸체에 탄력적으로 설치되어 드릴단부에서 길이방향으로 출몰하는 돌출부재를 가지는 것을 특징으로 한다.In the implant drill for maxillary sinus elevation of the present invention for achieving the above object, the cutting groove is formed on the outer peripheral surface of the cylindrical body is provided with a central axis provided with a shank in the implant drill mounted on a general dental handpiece, the body It is characterized in that it has a protruding member that is elastically installed in and protrudes in the longitudinal direction from the drill end.

이때 상기 돌출부재 선단은 라운딩처리되고, 돌출부재는 상기 몸체에 길이방향으로 형성된 관통공 내부에 스프링에 의하여 지지되도록 삽입된 것을 특징으로 한다.In this case, the tip of the protruding member is rounded, and the protruding member is inserted to be supported by a spring in the through hole formed in the longitudinal direction of the body.

그리고 상기 돌출부재에는 단턱이 형성되고 관통공에는 내턱이 형성되어, 상기 단턱과 내턱이 서로 맞물려 돌출부재가 관통공에서 이탈되지 않도록 한 것을 특징으로 한다.The protruding member is formed with a stepped jaw, and the through hole is formed with an inner jaw, so that the step and the inner jaw are engaged with each other so that the protruding member is not separated from the through hole.

한편 상기 몸체 외주면에는 플랜지가 구비되어 드릴이 삽입되는 길이가 일정하게 조절되는 것을 특징으로 한다.On the other hand, the outer peripheral surface of the body is provided with a flange is characterized in that the length of the drill is constantly adjusted.

이하, 첨부도면에 의거하여 본 발명에 따른 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1에 도시되어진 바와 같이 본 발명에 의한 상악동 거상술을 위한 임플란트 드릴(A)은 크게 연결체(10)와, 드릴날(20)과, 돌출부재(30)가 결합되어 이루어 진다.As shown in Figure 1, the implant drill (A) for maxillary sinus elevation according to the present invention is largely made by connecting the connector 10, the drill blade 20, and the protruding member 30.

상기 연결체(10)는 지름 4-5mm 내외인 원판형의 것으로, 그 하부면에 자체의 외경보다 작은 외경을 갖는 원형 걸림테(11)가 형성되어진 것이고, 그 상부 중심에 생크부(12a)를 구비한 중심축(12)이 마련되어진 것이며,The connecting body 10 has a disk shape having a diameter of about 4-5 mm, and a circular hook frame 11 having an outer diameter smaller than its outer diameter is formed on a lower surface thereof, and the shank portion 12a is formed at the upper center thereof. Is provided with a central axis 12 having,

상기 드릴날(20)은 연결체(10)에 비해 그 직경이 다소 작은 지름 3mm 내외인 원통형의 것으로, 몸체(20') 외주면에 나선형 컷팅홈(21)이 형성되어진 것이고, 수직방향 중심부에 상, 하로 이어지는 지름 2mm 내외인 관통공(22)이 형성되어진 것이며,The drill blade 20 is a cylindrical shape having a diameter of about 3mm and smaller than that of the connecting body 10, and a spiral cutting groove 21 is formed on the outer circumferential surface of the body 20 ', and the image is located at the center of the vertical direction. , A through hole 22 having a diameter of about 2 mm and extending downward is formed,

상기 돌출부재(30)는 드릴날(20)의 관통공(22) 직경과 동일하거나 이보다 작은 직경을 갖는 원형봉 형태의 것으로, 그 선단이 라운딩처리 되어진 것이고, 그 타단에는 스프링(32)과 접하는 형태의 것이어서 스프링(32) 탄성에 의해 일정범위 이내에서 전, 후진이 가능한 것이다.The protruding member 30 is in the form of a circular rod having a diameter equal to or smaller than the diameter of the through hole 22 of the drill blade 20, and its tip is rounded, and the other end is in contact with the spring 32. Since it is of a form, the spring 32 can be moved forward and backward within a predetermined range by elasticity.

여기서, 돌출부재(30)는 드릴날(20)의 관통공(22)에 내장 설치되는데,Here, the protruding member 30 is installed in the through hole 22 of the drill blade 20,

도 2에 도시되어진 바와 같이 라운딩처리된 선단이 드릴날(20)의 하단 외부로 드러나도록 설치되고, 반대 타단에 스프링(32)이 위치하며, 상기 스프링은 연결체에 의해 지지된다.As shown in FIG. 2, the rounded end is installed to be exposed to the outside of the lower end of the drill blade 20, and the spring 32 is positioned at the other end thereof, and the spring is supported by the connecting body.

그리고, 돌출부재(30)가 내장 설치된 드릴날(20)은 그 상단에 연결체(10)의 걸림테(11)가 결합되어 연결체(10)와 일체화되는데,And, the drill blade 20 is installed protruding member 30 is coupled to the engaging frame 11 of the connecting member 10 is integrated with the connecting member 10, the upper end thereof,

드릴날(20) 상단에 연결체(10)의 걸림테(11)가 결합되는 방식은 나사결합방식, 용접방식 등 어느 방식을 사용하여도 무방하며 이는 일정수준 이상의 체결력이 보장되는 것을 전제로 한다.The engaging frame 11 of the connector 10 is coupled to the upper end of the drill blade 20 may be any method such as a screw coupling method, a welding method may be used, which presupposes that a certain level of fastening force is ensured. .

상기와 같은 본 발명을 통해 상악골을 천공하는 과정은 도 3에 도시되어진 바와 같은 순서로 이루어지며 이를 상세히 설명하면 다음과 같다.The process of drilling the maxilla through the present invention as described above is made in the order as shown in Figure 3 described in detail as follows.

먼저, 연결체(10)의 생크부(12a)를 치과용 핸드피스 구동부에 장착하여 전원 인가시 드릴(A) 전체가 회전할 수 있도록 한 상태에서, 도 3a에 도시되어진 바와 같이 드릴날(20) 선단이 시술부위에 접근하도록 한다.First, in the state in which the shank portion 12a of the connecting body 10 is mounted on the dental handpiece driving unit so that the entire drill A can rotate when the power is applied, the drill blade 20 as shown in FIG. 3A. ) Make the tip close to the treatment area.

상기 상태에서 시술자가 힘을 가하여 드릴날(20) 선단이 시술부위에 밀착되도록 한 후 핸드피스에 전원을 인가하여 드릴(A)을 회전키키게 되면, When the operator in the above state by applying a force to the tip of the drill blade 20 is in close contact with the treatment site and then applying power to the handpiece to turn the drill (A),

도 3b에 도시되어진 바와 같이 드릴날(20) 전방으로 일부 드러나 있던 돌출부재(30)는 상악골(40)과의 접촉에 의해 그 후방에 위치한 스프링(32)이 압착되면서 뒤로 밀려나게 되므로 돌출부재(30)를 감싸고 있는 드릴날 선단이 상악골(40)을 파고들며 천공이 이루어지게 되는 것이고,As shown in FIG. 3B, the protruding member 30 partially exposed toward the front of the drill blade 20 is pushed backward while the spring 32 positioned at the rear thereof is compressed by the contact with the maxilla 40. 30) the end of the drill that surrounds the perforation is made by digging the maxilla (40),

상악골(40) 천공이 완료되어 드릴날(20) 선단이 빈공간을 감싸고 있는 형태의 상악동내막(50)에 이르는 순간 돌출부재(30)를 누르고 있던 상악골(40)에 의한 압력이 순간적으로 해제되므로 도 3c에 도시되어진 바와 같이 돌출부재(30)는 스프링(32) 탄성에 의해 전방으로 돌출되면서 상악동내막(50)을 빈공간으로 들어올리게 되므로 골이식재를 투입할 수 있는 공간을 손쉽게 확보할 수 있게 되는 것이다.When the maxillary bone 40 is completed and the tip of the drill blade 20 reaches the maxillary sinus lining 50 of the shape surrounding the empty space, the pressure by the maxillary bone 40 holding the protruding member 30 is released momentarily. As shown in FIG. 3c, the protruding member 30 protrudes forward by the elasticity of the spring 32 and thus lifts the maxillary sinus lining 50 into the empty space so that the bone graft material can be easily provided. Will be.

여기서, 돌출부재(30)가 드릴날(20)의 관통공(22) 내부로부터 돌출되어 상악동내막(50)과 접하는 동안에 돌출부재(30) 선단이 상악동내막(50)을 손상시킬 우려가 있을 수 있으나, 본 발명에서는 돌출부재(30) 선단을 라운딩처리 하였으므로 돌 출부재(30) 선단에 의해 상악동내막(50)이 손상되는 것을 방지할 수 있게 되는 것이며,Here, the tip of the protruding member 30 may damage the maxillary sinus lining 50 while the protruding member 30 protrudes from the inside of the through hole 22 of the drill blade 20 to contact the maxillary sinus lining 50. However, in the present invention, since the tip of the protruding member 30 is rounded, the maxillary sinus lining 50 may be prevented from being damaged by the tip of the protruding member 30.

이때, 돌출부재(30)에는 길이방향 중간에 단턱(31)이 형성되어 있고, 드릴날(20)의 관통공(22) 길이방향 중간에 내턱(22a)이 형성되어 있으므로 상기 단턱(31)과 내턱(22a)의 맞물림으로 인하여 돌출부재(30)는 관통공(22) 내부로부터 이탈되지 않으면서 돌출부재(30)의 돌출정도가 일정범위 이내에서 이루어질 수 있게 되는 것이다.At this time, the step member 31 is formed in the middle of the longitudinal direction in the protruding member 30, and the inner step 22a is formed in the middle of the longitudinal direction of the through hole 22 of the drill blade 20. Due to the engagement of the inner jaw 22a, the protruding member 30 may be formed within a predetermined range without protruding from the inside of the through hole 22.

한편, 드릴날(20)이 상악골(40)을 천공하고 돌출부재(30)가 상악동내막(50)을 들어올린 이후에도 시술자는 드릴(A)을 밀고 있는 상태이므로 시술자가 힘을 가하는 방향 즉, 상악동을 향해 드릴날(20)이 더 진행할 수 있으나, 도 3d에 도시되어진 바와 같이 드릴날(20)이 더 진행한다 하더라도 드릴날(20) 보다 더 큰 직경을 갖는 연결체(10)가 천공 시발점 둘레의 상악골(40)에 걸리게 되므로 더 이상의 진행은 이루어질 수 없어 드릴날(20)이 상악골(40) 내부로 삽입되는 정도를 제한할 수 있게 되는 것이다.On the other hand, even after the drill blade 20 drills the maxillary bone 40 and the protruding member 30 lifts the maxillary sinus lining 50, the operator pushes the drill A, so that the operator applies the force, that is, the maxillary sinus. Although the drill blade 20 may proceed further toward, the connector 10 having a larger diameter than the drill blade 20 has a periphery starting point even if the drill blade 20 proceeds further, as shown in FIG. 3D. Since the upper jaw (40) is caught so that no further progress can be made to the extent that the drill blade 20 is inserted into the maxilla (40).

이상에서는 본 발명의 적용부위를 상악동으로 하였으나 이에 한정되는 것은 아니므로 하치조신경이 지나가는 하악구치부 등 적용부위를 변경하여 사용하는 것이 가능한 것이고, 그 형태 및 크기 또한 한정되지 아니하므로 청구범위에서 청구하는 본 발명의 요지를 벗어나지 않는 범위 안에서 변형 가능한 것이며, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.In the above, the application site of the present invention is the maxillary sinus, but the present invention is not limited thereto.
