일반적으로, 임플란트는 본래의 인체조직이 상실되었을 때, 인체조직을 대신할 수 있는 대치물을 의미하지만, 치과에서는 인공으로 만든 치아를 이식하는 것을 말한다. 상실된 치근을 대신할 수 있도록 인체에 거부반응이 없는 티타늄 등으로 만든 픽스츄어를 치아가 빠져나간 치조골에 심은 뒤, 인공치아를 고정시켜 치아의 기능을 회복하도록 하는 시술이다.In general, an implant means a substitute that can replace human tissue when the original human tissue is lost, but in the dentist, an implanted artificial tooth is implanted. In order to replace the lost tooth root, a fixture made of titanium, which does not have a rejection reaction on the human body, is planted in the alveolar bone where the tooth falls out, and the artificial tooth is fixed to restore the function of the tooth.
일반 보철물이나 틀니의 경우 시간이 지나면 주위 치아와 뼈가 상하지만, 임플란트는 주변 치아조직의 손상을 방지할 수 있으며 이차적인 충치 발생요인이 없기 때문에 안정적으로 사용할 수 있다. 또한, 임플란트는 자연 치아와 동일한 구조를 가지므로 잇몸의 통증 및 이물감이 전혀 없으며, 관리만 잘하면 반영구적으로 사용할 수 있는 장점이 있다. In the case of a general prosthesis or denture, the surrounding teeth and bones are damaged over time, but the implant can prevent damage to the surrounding dental tissue and can be used stably because there is no secondary decay factor. In addition, since the implant has the same structure as the natural teeth, there is no pain and foreign body feeling of the gums, and there is an advantage that can be used semi-permanently if you manage well.
도 1은 종래의 임플란트 시술과정을 나타낸 흐름도이다. 1 is a flowchart illustrating a conventional implant procedure.
도 1에서 보는 바와 같이, 종래의 임플란트 시술과정은 픽스츄어(fixture)를 치조골에 식립하는 1차 시술(s1,s2,s3,s4)과, 픽스츄어가 치조골에 골융합되는 시간(3~6개월)을 기다린 후 최종보철물(crown)을 고정시키는 과정(s5,s6)을 포함한다.As shown in Figure 1, the conventional implant procedure is a first procedure (s1, s2, s3, s4) to place the fixture in the alveolar bone (s1, s2, s3, s4), the time the bone is fused to the alveolar bone (3-6 months After waiting for), the process includes fixing the final prosthesis (crown) (s5, s6).
먼저, 1차 시술은 치아가 결손된 부분의 잇몸을 여는 잇몸 제거 단계(s1), 픽스츄어가 식립될 천공을 형성하는 다단계 드릴링 단계(s2), 그리고 픽스츄어 식립 단계(s3), 식립된 픽스츄어에 임시치아를 결합하는 단계(s4)로 이루어진다. First, the first procedure is a gum removal step (s1) of opening the gum of a portion where a tooth is missing (s1), a multi-stage drilling step (s2) for forming a perforation for fixing the fixture, and a fixture placement step (s3), the implanted fix Coupling the temporary teeth to the cheure (s4) is made.
상세히, 잇몸 제거 단계(s1)에서 티슈 펀치 등을 통해 잇몸을 제거하고 픽스츄어가 식립되는 위치의 치조골을 노출시킨다. 그리고, 치조골의 노출된 부분에 다단계 드릴링 단계(s2)를 거쳐 픽스츄어 식립을 위한 천공을 형성하게 된다. In detail, in the gum removal step (s1), the gum is removed through a tissue punch or the like, and the alveolar bone at the position where the fixture is placed is exposed. Then, through the multi-stage drilling step (s2) in the exposed portion of the alveolar bone to form a perforation for fixing the fixture.
이때, 상기 다단계 드릴링 단계(s2)는 초기 홀을 형성하는 단계, 홀을 확장하는 단계, 홀의 내부에 나사산을 형성하는 단계, 그리고 홀 내부의 잔존 치조골을 제거하는 단계 등으로 이루어질 수 있으며, 시술에 사용하는 드릴의 종류와 드릴링 방법에 따라 다양하게 이루어질 수 있다.At this time, the multi-stage drilling step (s2) may be formed by forming an initial hole, expanding the hole, forming a screw thread in the hole, and removing the remaining alveolar bone in the hole. It can be variously made according to the type of drill used and the drilling method.
그리고, 상기 다단계 드릴링 단계(s2)를 거쳐 형성된 천공에 픽스츄어를 식립하고(s3), 식립된 픽스츄어에 임시치아를 결합시키면(s4) 1차 시술과정은 마무리된다.Then, the fixture is implanted in the perforation formed through the multi-stage drilling step (s2) (s3), and the first procedure is completed by combining the temporary teeth with the implanted fixture (s4).
여기서, 상기 천공에 식립되는 픽스츄어는 인공치아의 뿌리역할을 하게 된다. 따라서, 치조골이 픽스츄어와 골융합을 형성하는 회복과정이 빠르고 안정적으로 진행되고, 골융합 후 치조골과 픽스츄어의 안정적인 결합력을 제공하기 위해서는 다단계 드릴링 단계(s2)에서 정확한 천공을 형성하는 것이 매우 중요하며, 임플란트 시술을 통한 인공치아 형성의 완성도를 좌우하게 된다. Here, the fixture placed in the perforation is to play the role of the root of the artificial tooth. Therefore, the recovery process of the alveolar bone forming the fixture and bone fusion is fast and stable, and in order to provide a stable coupling force between the alveolar bone and the fixture after the bone fusion, it is very important to form an accurate perforation in the multistage drilling step (s2), The completeness of the artificial tooth formation through the implant procedure will be influenced.
이때, 상기 임시치아는 힐링 어버트먼트 및 커버 스크류를 포함한다. 여기서, 상기 힐링 어버트먼트 및 상기 커버 스크류는 식립된 픽스츄어가 치조골에 골융합되는 동안 픽스츄어에 삽입되며, 상기 픽스츄어의 내측에 잇몸이나 이물질 등이 유입되는 것을 방지하여 픽스츄어 내부가 손상되는 것을 예방하게 된다.In this case, the temporary tooth includes a healing abutment and a cover screw. Here, the healing abutment and the cover screw are inserted into the fixture while the implanted fixture is fused to the alveolar bone, and the inside of the fixture is damaged by preventing gum or foreign matter from flowing into the inside of the fixture. Will be prevented.
그리고, 상기 픽스츄어에 상기 임시치아를 결합시키고 3개월 내지 6개월 정도의 기간 동안 치조골이 회복되는 것을 기다린 후, 상기 임시치아를 제거하고 지대부(abutment)를 결합하게 된다(s5). 마지막으로, 상기 지대부에 최종보철물(crown)을 결합하면 임플란트 시술이 완료될 수 있다(s6).Then, the temporary tooth is coupled to the fixture, and after waiting for the alveolar bone to recover for a period of about 3 to 6 months, the temporary tooth is removed and the abutment is coupled (s5). Finally, when the final prosthesis (crown) is coupled to the zone, the implant procedure can be completed (s6).
한편, 상술된 시술과정에서 픽스츄어가 식립될 위치에 정확한 깊이와 방향으로 천공을 형성하는 것은 초심자뿐만 경험자에게도 매우 어려운 작업이다. 따라서, 상기 천공 형성을 위한 드릴링 작업에는 스탠트라고 하는 수술 가이드 도구를 사용하여 시술이 진행된다.On the other hand, it is very difficult for beginners as well as experienced users to form perforations in the exact depth and direction at the position where the fixture is to be placed in the above-described procedure. Therefore, the drilling process for forming the perforation is performed using a surgical guide tool called a stent.
여기서, 상기 스탠트는 CT촬영을 통해 구강 내의 치조골 형상을 획득하고, 구강 내의 프로파일을 본떠 형성된 석고모델을 통해 치아 및 잇몸의 형상을 획득한다. 그리고, 이를 영상 정합하여 시뮬레이션을 통해 임플란트 시술을 계획하고, 상기 계획에 맞게 수술을 안내할 수 있는 스탠트를 제작하게 된다. Here, the stent acquires the alveolar bone shape in the oral cavity through CT imaging, and obtains the shape of the teeth and the gums through the plaster model formed after the profile in the oral cavity. And, by matching the image to plan the implant procedure through the simulation, to produce a stent to guide the operation in accordance with the plan.
이때, 상기 스탠트에는 구강 내에 고정된 상태에서 임플란트 시술 계획에 대응되는 픽스츄어의 식립 위치를 안내하는 안내공이 형성된다. 그리고, 상기 안내공의 내주는 천공 형성시 사용되는 드릴의 외주를 회전지지하여 드릴링 과정에서 천공이 정확한 방향과 깊이로 형성되도록 안내할 수 있다. At this time, the stator is formed with a guide hole for guiding the placement position of the fixture corresponding to the implant treatment plan in a fixed state in the oral cavity. In addition, the inner circumference of the guide hole may rotate to support the outer circumference of the drill used to form the perforation to guide the perforation to be formed in the correct direction and depth during the drilling process.
그러나, 종래에는 상기 안내공이 고속회전되는 드릴에 의해 쉽게 열화됨에 따라 천공 형성시 안정적으로 드릴의 회전을 지지하지 못하는 문제점이 있었으며, 이에 따라, 형성된 천공의 정확도가 감소하여 임플란트 시술의 전체적인 완성도를 저하시키는 문제점이 있었다.However, in the related art, as the guide hole is easily deteriorated by the high-speed rotating drill, there is a problem in that it does not stably support the rotation of the drill when forming the perforation. As a result, the accuracy of the formed perforation decreases, thereby lowering the overall completeness of the implant procedure. There was a problem letting.
또한, 드릴링 단계를 거쳐 형성된 천공에는 픽스츄어가 식립되는데, 픽스츄어의 내측에는 헥사홀이 형성되며, 상기 헥사홀에 임시치아(힐링 어버트먼트/커버 스크류)나 지대부(어버트먼트)의 헥사돌기가 삽입되어 고정된다. 이때, 상기 헥사홀의 내부에 접착제를 함께 삽입하여 고정시키게 된다. 그리고, 상기 헥사홀 및 상기 헥사돌기는 압력 분산에 유리한 벌집 형태로 구비되며, 상기 헥사돌기는 기설정된 방향으로 삽입될 때 상기 헥사홀의 내부에 정확하게 삽입될 수 있다. In addition, a fixture is implanted in the perforation formed through the drilling step, and a hexa hole is formed inside the fixture, and a temporary tooth (healing abutment / cover screw) or abutment part (abutment) is formed in the hexa hole. Hexadex is inserted and fixed. At this time, the adhesive is fixed together by inserting the inside of the hexa-hole. The hexa-holes and the hexa-projections are provided in a honeycomb form, which is advantageous for pressure dispersion, and the hexa-projections may be accurately inserted into the hexa-holes when inserted in a predetermined direction.
그러나, 종래에는 픽스츄어 내측의 헥사홀의 배치각도가 일정하게 정렬되지 못하기 때문에 픽스츄어가 식립된 각도에 따라 임시치아나 지대부의 삽입각도가 달라지게 되었다. However, in the related art, since the arrangement angle of the hexa hole inside the fixture is not aligned constantly, the insertion angle of the temporary tooth or the abutment portion is changed according to the angle at which the fixture is placed.
상기 임시치아 중 커버 스크류는 픽스츄어 내부의 텅빈 공간으로 음식물이 침투하여 감염을 발생시키거나 잇몸이 유입되어 픽스츄어와 치조골 사이의 결합력을 감소시키는 것을 방지하고, 힐링 어버트먼트는 커버 스크류의 역할과 함께 재생되는 잇몸의 형태를 잡아주기 위해 사용된다. The cover screw of the temporary tooth prevents food from infiltrating into the empty space inside the fixture, causing infection or influx of gums, thereby reducing the bonding force between the fixture and the alveolar bone, and the healing abutment serves as the cover screw. It is used to catch the shape of the gum that is being played with.
이때, 상기 픽스츄어의 식립된 각도가 임플란트 시술 계획에 따른 힐링 어버트먼트의 배치각도와 상이한 경우에 상기 픽스츄어의 배치각도를 바로 잡기 위해 여러번의 시행착오를 통해 끼웠다 뺐다하는 작업이 필요하고, 치조골이 손상되거나 치고골의 손실이 증가되는 경우에 발생하여 회복기간이 늘어나는 문제점이 있었다.In this case, when the angle of implantation of the fixture is different from the placement angle of the healing abutment according to the implant treatment plan, it is necessary to insert and reinsert it through several trials and errors to correct the placement angle of the fixture. When the alveolar bone is damaged or the loss of the pubic bone increases, there is a problem in that the recovery period is increased.
또한, 상기 지대부의 상측에는 최종보철물이 결합되는 다각 돌기가 형성되는데, 상기 다각 돌기의 방향이 지대부의 삽입각도에 따라 달라지게 된다. 이에 따라, 최종보철물 제작시 픽스츄어 식립 후 지대부의 방향을 반영하여 제작해야 하므로 준비기간 및 제작기간이 길어지게 되는 문제점이 있었다.In addition, the upper side of the abutment portion is formed a polygonal projection to which the final prosthesis is coupled, the direction of the polygonal projection will vary depending on the insertion angle of the abutment portion. Accordingly, when the final prosthesis is manufactured, the preparation period and the production period become longer because the fabrication of the final prosthesis should be performed by reflecting the direction of the zone.
상기와 같은 문제점을 해결하기 위하여, 임플란트 시술과정에서 픽스츄어의 식립 위치 및 상기 픽스츄어의 식립을 위한 천공 형성을 안내하되, 픽스츄어 식립 및 보철물 결합의 편의성과 정확성이 향상되는 치아 임플란트용 가이드 스탠트를 제공하는 것을 해결과제로 한다. In order to solve the above problems, the guide stand for the dental implant that improves the positioning and positioning of the fixture in the implantation procedure and the formation of the perforation for the implantation of the fixture, the convenience and accuracy of the fixture placement and prosthesis coupling Providing a test is a challenge.

Here, the guide protrusions are aligned at a predetermined placement angle so that the hexa-projections of the abutments to be fitted to the hexa-holes of the fixture are aligned with the placement angles of the crowns manufactured according to the 3D image acquisition data. It is preferable to be fixed to the edge of the coupling hole.
그리고, 상기 3차원 이미지 획득데이터에 따라 제조되는 크라운의 배치각도에 대응하여 상기 픽스츄어의 헥사홀에 형합되는 어버트먼트의 헥사돌기가 정렬되도록, 상기 가이드 돌기부의 원주방향 폭은 상기 어버트먼트의 가이드면 폭과 대응됨이 바람직하다. The circumferential width of the guide protrusion may be aligned so that the hexa protrusions of the abutments formed in the hexa-holes of the fixture are aligned with the arrangement angles of the crowns manufactured according to the 3D image acquisition data. It is preferable to correspond to the width of the guide surface of the.

상기의 해결 수단을 통해서, 본 고안에 따른 치아 임플란트용 가이드 스탠트는 다음과 같은 효과를 제공한다. Through the above solution, the guide stent for dental implants according to the present invention provides the following effects.
첫째, 상기 가이드 스탠트는 가이드 돌기부가 상기 3차원 이미지 획득데이터에 따라 제조되는 크라운의 배치각도에 대응하여 결합되므로, 상기 가이드 돌기부에 픽스츄어/어버트먼트를 정렬함으로써 크라운이 기설정된 배치각도로 상기 어버트먼트에 정확하게 결합될 수 있다. First, the guide stent is combined with the guide protrusion corresponding to the arrangement angle of the crown manufactured according to the 3D image acquisition data, so that the crown is aligned with the preset placement angle by aligning the fixture / abutment to the guide protrusion. It can be coupled precisely to the abutment.
이를 통해, 픽스츄어의 식립각도에 대응하여 크라운을 제조하는 것이 아니라 가이드 스탠트를 제작할 때 크라운의 배치각도를 설정하여 제조할 수 있으므로 임플란트 시술을 준비하고, 각종 보철물을 제작하는 시간을 현저히 절감할 수 있으며, 한번의 시술로 잇몸 제거, 픽스츄어 식립 천공 드릴링, 픽스츄어 식립 및 어버트먼트/크라운 설치를 완료할 수 있는 기반기술장치를 제공할 수 있다.Through this, it is possible not to manufacture the crown corresponding to the implantation angle of the fixture, but to manufacture by setting the placement angle of the crown when manufacturing the guide stent, thus preparing the implant procedure and significantly reducing the time for manufacturing various prostheses. It can provide a base technology device that can complete the removal of gum, fixation drilling drilling, fixation placement and abutment / crown installation in one operation.
둘째, 상기 가이드 돌기부의 원주방향 폭은 어버트먼트의 가이드면 폭과 대응되도록 구비되어, 시술자가 가이드면을 가이드 돌기부에 맞춰 정렬하기만 하면 픽스츄어의 헥사홀, 어버트먼트의 헥사돌기가 자동으로 정렬되므로 손쉬운 정렬이 가능하여 시술시간이 절감될 수 있다. Second, the circumferential width of the guide protrusion is provided to correspond to the width of the guide surface of the abutment, so that the operator can align the guide surface with the guide protrusion, the hexa hole of the fixture and the hexa protrusion of the abutment are automatically Because it is aligned with, easy alignment is possible, so the procedure time can be reduced.
셋째, 상기 가이드 스탠트의 결합홀 상부 테두리에 형성된 정렬홈부는 상기 3차원 이미지 획득데이터에 따라 제조되는 크라운의 배치각도에 대응하여 상기 가이드 돌기부를 정확하게 삽입하여 고정할 수 있으므로 픽스츄어 및 어버트먼트 정렬의 정확성이 향상될 수 있으며, 가이드 스탠트 제작 시점에서 제조된 크라운을 임플란트 시술계획에 맞게 구강 내에 정확하게 결합시킬 수 있다.Third, the alignment groove formed on the upper edge of the coupling hole of the guide stent can be accurately inserted and fixed to the guide protrusion corresponding to the arrangement angle of the crown manufactured according to the 3D image acquisition data, so that the fixture and abutment Alignment accuracy can be improved, and crowns made at the time of guide stent fabrication can be precisely incorporated into the oral cavity to fit the implant procedure.
넷째, 상기 슬리브는 가이드 돌기부가 상기 결합홀의 정렬홈부에 삽입되어 회전되지 않도록 고정되며, 상기 결합홀의 내주면에 돌설된 이탈방지돌기가 중공형 부싱부의 이탈방지홈부에 삽입되어 걸림 고정됨에 따라 단순히 방향을 맞춰 끼워 삽입하는 것으로 견고하게 결합되며, 가이드 돌기부가 설정된 위치로 자동 정렬되므로 제품의 조립성이 향상될 수 있다. Fourth, the sleeve is fixed so that the guide protrusion is inserted into the alignment groove of the coupling hole so as not to rotate, and the separation prevention protrusion protruding from the inner circumferential surface of the coupling hole is simply inserted into the separation prevention groove of the hollow bushing to lock the direction. It is firmly coupled by inserting and fitting, and the assembly of the product can be improved because the guide protrusion is automatically aligned to the set position.

도 2 내지 도 5c에서 보는 바와 같이, 본 고안의 일실시예에 따른 치아 임플란트용 가이드 스탠트(100)는 스탠트 몸체(10)와 슬리브(20)를 포함한다. 여기서, 상기 치아 임플란트용 가이드 스탠트(100)는 구강 내부의 3차원 정보와 이미지 정보를 통해 획득된 3차원 이미지 획득데이터로 설정된 프로파일로 형성되며, 이후 행해지는 제반 임플란트 시술을 안내하는 역할을 한다.2 to 5c, the guide stent 100 for a dental implant according to an embodiment of the present invention includes a stent body 10 and a sleeve 20. Here, the guide implant 100 for the dental implant is formed of a profile set by the three-dimensional image acquisition data obtained through the three-dimensional information and the image information in the oral cavity, and serves to guide the overall implant operation to be performed thereafter .
상세히, 환자의 CT촬영을 수행하여 통해 구강 내의 치조골 및 치아 등에 대한 3차원 정보를 획득한다. 또한, 오랄 스캐닝이나 모델 스캐닝 혹은 석고모델을 통해 치아, 잇몸 등 환자의 치주조직의 외형에 대한 이미지 정보를 획득한다. 이후, 상기 3차원 이미지 획득데이터는 상기 3차원 정보 및 이미지 정보를 정합하여 얻어질 수 있다. In detail, CT imaging of the patient is performed to obtain 3D information about alveolar bone and teeth in the oral cavity. In addition, image information about the appearance of the patient's periodontal tissue such as teeth and gums is obtained through oral scanning, model scanning, or plaster model. Thereafter, the 3D image acquisition data may be obtained by matching the 3D information and the image information.
그리고, 상기 3차원 이미지 획득데이터에 따라 환자의 해부학적 보철관계를 고려하여 시뮬레이션 후 임플란트 시술 계획을 수립할 수 있다. In addition, an implant procedure plan can be established after simulation in consideration of the anatomical prosthetic relationship of the patient according to the 3D image acquisition data.
이때, 상기 3차원 이미지 획득데이터에 따라 구강 내 치주 조직의 형상을 가지도록 설정된 프로파일로 가이드 스탠트(100)의 스탠트 몸체(10)를 형성한다. 상기 스탠트 몸체(10) 내에는 상기 임플란트 시술 계획에 따른 픽스츄어 식립 위치를 안내하고 상기 픽스츄어 식립 위치에 천공을 형성하기 위한 드릴링을 안내하는 슬리브(20)가 구비된다.At this time, the stent body 10 of the guide stent 100 is formed with a profile set to have the shape of the periodontal tissue in the oral cavity according to the 3D image acquisition data.

Meanwhile, referring to FIGS. 2 to 3, the sleeve 20 is inserted into and coupled to each of the coupling holes 11, and includes a hollow bushing 23 and a guide protrusion 21. Here, the coupling hole 11 is formed corresponding to the fixture placement position, the hollow bushing portion 23 is formed with a guide hole 22 for rotating the implant drill is supported along the inner circumference. In addition, the guide hole 22 is rotatably supported by a drill for forming a hole in which the fixture is to be placed, and the depth, formation direction, diameter, etc. of the hole may be guided by the guide hole 22.
따라서, 상기 가이드홀(22)은 상기 드릴의 외주면에 접하여 안내할 수 있는 직경으로 구비되는 것이 바람직하며, 상기 가이드홀(22)의 상측 테두리는 상기 드릴의 삽입깊이를 조절할 수 있는 높이범위에 형성되는 것이 바람직하다.Therefore, the guide hole 22 is preferably provided with a diameter that can be in contact with the outer peripheral surface of the drill, the upper edge of the guide hole 22 is formed in the height range that can adjust the insertion depth of the drill It is desirable to be.

Of course, the separation prevention groove portion 23a may be formed along the circumferential direction on the outer circumferential surface of the hollow bushing portion 23. At this time, the separation prevention groove portion 23a may be inserted into the separation prevention projection formed along the circumferential direction on the inner circumferential surface of the coupling hole 11 and locked.
이로 인해, 상기 슬리브(20)는 상기 가이드 돌기부(21)에 의해 회전되지 않도록 고정되며, 상기 이탈방지홈부(23a)와 상기 이탈방지돌기가 상호 결합되어 상기 결합홀(11)에 고정될 수 있다. 따라서, 단순히 방향을 맞춰 끼워 삽입하는 것으로도 이들이 상호 견고하게 결합될 뿐만 아니라, 가이드 돌기부가 설정된 위치로 자동 정렬되므로 제품의 조립성이 향상될 수 있다. Thus, the sleeve 20 is fixed so as not to rotate by the guide protrusion 21, and the separation preventing groove 23a and the separation preventing protrusion may be coupled to each other and fixed to the coupling hole 11. . Therefore, by simply inserting them in the right direction, they are not only firmly coupled to each other, but also the assembly of the product can be improved since the guide protrusions are automatically aligned to the set position.

이에 따라, 상기 천공에 식립된 픽스츄어(3)에 어버트먼트(4)가 결합된 후에 상기 어버트먼트(4)에 배치각도에 따라 크라운을 제조하는 것이 아니라, 가이드 스탠트(100)를 제작하는 단계에서 상기 크라운의 배치각도를 설정할 수 있으므로 임플란트 시술을 준비하고, 각종 보철물을 제작하는 시간을 현저히 절감할 수 있다.Accordingly, after the abutment 4 is coupled to the fixture 3 placed in the perforation, the guide stand 100 is not manufactured according to the placement angle of the abutment 4. Since the arrangement angle of the crown can be set in the manufacturing step, it is possible to significantly reduce the time for preparing the implant procedure and manufacturing various prostheses.
이에 따라, 어버트먼트/크라운이 기제조된 경우에 한번의 시술로 잇몸 제거, 픽스츄어 식립 천공 드릴링, 픽스츄어 식립 및 어버트먼트/크라운 설치를 완료할 수 있는 기반기술장치를 제공할 수 있다.Accordingly, in the case where the abutment / crown is manufactured, it is possible to provide a base technology device capable of completing gum removal, fixation drilling, drilling fixation, and abutment / crown installation in one operation. .
또한, 상기 가이드 돌기부(21)는 상기 중공형 부싱부(23) 외주의 단일 개소에 돌출됨이 바람직하다. 이에 따라, 상기 가이드 돌기부(21)는 기설정된 상기 크라운의 배치각도에 따라 상기 픽스츄어의 배치각도, 상기 어버트먼트의 배치각도를 정확하게 안내할 수 있다. In addition, the guide protrusion 21 is preferably protruded in a single location on the outer circumference of the hollow bushing 23. Accordingly, the guide protrusion 21 may accurately guide the placement angle of the fixture and the placement angle of the abutment according to the preset placement angle of the crown.
