Description

임플란트 정밀식립용 매개부싱 및 이를 이용한 임플란트 정밀식립 장치Intermediate bushing for precise implant placement and precision implant device using the same
본 발명은 임플란트 정밀식립용 매개부싱 및 이를 이용한 임플란트 정밀식립 장치에 관한 것으로서, 천공용 드릴이 유도되며 스텐트에 고정된 유도부싱의 내주면에 결합하는 임플란트 정밀식립용 매개부싱 및 이를 이용한 임플란트 정밀식립 장치에 관한 것이다.The present invention relates to an intermediate implant bushing for precise implantation and an implant precision implantation device using the same, which is a drill for guide drilling and is coupled to the inner peripheral surface of the implant bushing fixed to the stent, and the implant precision implantation device using the same It is about.
임플란트는 본래 인체의 조직이 상실되었을 때 이를 회복시켜 주는 대치물을 의미하지만 치과에서는 인공치아 이식을 말한다. 상실된 치아의 치근을 대신할 수 있도록, 인체에 거부반응이 없는 티타늄으로 만든 인공치근을 이가 빠져나간 치조골에 심어서 유착시킨 뒤 인공치아를 고정시켜 치아의 원래 기능을 회복하도록 하는 첨단시술이다.Implant is a substitute that recovers when the tissue of the human body is lost, but in the dentistry, it refers to an artificial tooth implant. It is a cutting-edge procedure that restores the original function of teeth by fixing artificial teeth after implanting artificial tooth roots made of titanium without rejection to the human alveolar bone to replace the lost tooth roots.
치아이식은 본래 고대에도 시행되었고, 16∼17세기에는 금과 상아로 만든 인공치아를, 20세기 초반에는 금이나 은·납·이리듐·철·코발트 합금 등으로 제작한 금속 임플란트가 개발되었다. 1940년대 이후 골막하 임플란트와 티타늄 블레이드 임플란트가 개발되며 대중화되었으나 수명이 짧고 성공률이 낮았다. 이후 1982년 캐나다 토론토에서 스웨덴의 브레네마르크(Branemark)가 15년 동안 연구한 골유착 임플란트를 발표한 뒤 성공률이 90％를 넘어 세계적으로 널리 대중화되었다. Dental implants were originally performed in ancient times. In the 16th and 17th centuries, artificial implants made of gold and ivory were developed. In the early 20th century, metal implants made of gold, silver, lead, iridium, iron and cobalt alloys were developed. Subperiosteal and titanium blade implants have been developed and popularized since the 1940s, but have short life spans and low success rates. Later, in 1982, after a 15-year study of osteoadhesive implants by Branemark of Sweden in Toronto, Canada, the success rate exceeded 90% and became popular worldwide.
일반 보철물이나 틀니의 경우 시간이 지나면 주위의 치아와 뼈가 상하지만 임플란트는 주위의 치아 조직을 상하지 않게 하는 장점이 있다. 또한 자연 치아와 기능이나 모양이 똑같으면서도 충치가 생기지 않으므로 반영구적으로 사용할 수 있다. 그러나 관리를 잘못하면 플러그나 치석 등이 생겨 주위 조직에 염증을 일으켜 치주질환 등을 야기할 수 있다.In the case of a general prosthesis or denture, the surrounding teeth and bones are damaged over time, but the implant has the advantage of not damaging the surrounding dental tissue. In addition, it can be used semi-permanently because the same function and shape as natural teeth does not cause tooth decay. However, poor management can lead to plugs and tartar, which can cause inflammation of surrounding tissues, leading to periodontal disease.
치과에서 임플란트를 시술하는 작업을 할 때, 일반적으로 드릴을 이용하여 치조골에 픽스츄어가 매식될 홈을 드릴링하는 작업을 수행하게 된다.When dental implants are performed, a drill is generally used to drill a groove into which the fixture is buried in the alveolar bone.
픽스츄어를 포함하는 임플란트의 식립은 환자마다 많은 차이가 있는데, 이는 환자의 치아의 상태나 임플란트 시술이 필요한 치아의 위치, 환자의 치조골의 상태 등 다양한 요인을 고려하여 임플란트의 식립 위치 및 깊이와 방향을 결정해야 하기 때문이다. 이렇게 결정된 임플란트의 식립 위치와 방향 및 깊이가 결정되면 이에 따라 드릴을 이용하여 치조골을 천공하는 작업을 수행하게 된다.The placement of implants including fixtures varies greatly from patient to patient, which is based on the various factors such as the patient's teeth, the position of the teeth requiring implant treatment, and the condition of the patient's alveolar bone. Because you have to decide. When the position, direction and depth of implantation are determined, the drilling of the alveolar bone is performed by using a drill.
치조골 천공을 위한 드릴링 작업은 초심자뿐만 아니라 경험자에게도 작업 과정에서 깊이 및 방향을 정확하게 가늠하기가 상당히 어렵다는 난점이 있다. 특히, 시술 경험이 풍부하지 않은 초보자의 경우 시술 도중 별도의 특별한 측정 단계 없이 드릴링된 깊이를 가늠한다는 것은 매우 어려운 것이다.Drilling work for alveolar bone drilling is difficult for beginners as well as experienced users to accurately measure depth and direction in the process. In particular, it is very difficult for beginners who are not experienced in the procedure to measure the drilled depth without any special measuring step during the procedure.
또한, 픽스츄어를 식립하기 위한 홈을 치조골에 드릴링할 때에, 시술자가 드릴에 힘을 가하여 드릴링 작업을 수행하면서 현재 어느 정도까지 깊이로 드릴링 작업이 이루어졌는지 판단하기가 용이하지 않은 관계로 소정의 깊이를 넘어서서 드릴링을 하게 되면 드릴이 치조골에 있는 신경을 손상시킬 우려가 있다.In addition, when drilling a groove for placing a fixture into the alveolar bone, the operator may apply a force to the drill to drill the drilling operation to a certain depth because it is not easy to determine to what extent the drilling operation is currently performed. If you drill beyond the drill may damage the nerves in the alveolar bone.
그 반대로 소정의 드릴링 깊이에 도달하기 전에 드릴링 작업을 종료한 경우에는 드릴된 홈의 깊이가 얕아서 픽스츄어 고정에 과도한 힘이 소용될 뿐만 아니라 이로 인해 홈 주위의 나사산이 손상되거나 홈에 고정될 픽스츄어가 완벽하게 고정되지 못하게 되어 추후 재시술을 하게 되는 문제가 발생한다.On the contrary, if the drilling operation is terminated before reaching the predetermined drilling depth, the drilled groove is shallow in depth, and excessive force is used to fix the fixture, which may damage the thread around the groove or fix the fixture to the groove. May not be completely fixed, causing problems in the future.
이러한 문제점을 해결하기 위하여, 스텐트라고 하는 보조 기구를 사용하게 된다.In order to solve this problem, an auxiliary device called a stent is used.
종래 통상적으로 사용한 스텐트의 제작 과정과 사용방법은 다음과 같다.The manufacturing process and the method of use of the conventionally used stent is as follows.
먼저, 임플란트 시술 전에 고무재질의 인상 재료를 이용하여 피시술자의 상악 또는 하악의 음형을 획득한 후 상기 음형에 석고를 부어 피시술자의 상악 또는 하악의 형상과 동일한 석고모형을 제작한다.First, before the implant procedure, using the impression material of the rubber material to obtain the sound of the maxillary or mandible of the subject and then pour gypsum on the sound to produce the same plaster model as the shape of the maxillary or mandible of the subject.
이어서, 이를 인공 교합기에 결합시켜 피시술자의 것과 거의 유사한 턱관절 및 상하악 치아를 구강 밖에서 재현한다.It is then coupled to an artificial articulator to reproduce outside the oral cavity of the jaw and maxillary teeth, which are almost similar to that of the subject.
이어서, 치아가 상실되어 임플란트를 시술할 위치에 투명한 재질의 가상의 치아 모형을 제작하며, 이것이 스텐트로 사용된다.Subsequently, the tooth is lost and a virtual tooth model is made of a transparent material at the position where the implant is to be treated, which is used as a stent.
이와 같이, 완성된 스텐트 중 드릴이 삽입될 위치에 소정의 마크를 하고, 스텐트의 외부에 천공할 방향을 지시하는 표시를 한 후, 상기 마크와 표시를 참고로 시술자는 드릴 등의 천공 도구를 이용하여 천공작업을 수행하게 된다.In this way, a predetermined mark is made at the position where the drill is to be inserted among the completed stents, a mark indicating the direction to be drilled to the outside of the stent, and the operator uses a drilling tool such as a drill with reference to the mark and the marking. To perform the drilling operation.
그러나, 상기 스텐트는 직접적으로 임플란트 드릴을 유도하지 못하는 문제점이 있다.However, there is a problem that the stent does not directly induce an implant drill.
따라서, 이러한 문제점을 해결하기 위해 스텐트의 몸체부에 유도부싱을 고정한 스텐트가 소개된다. 상기 유도부싱 내부로 다양한 크기의 천공용 드릴을 유도하기 위해 상기 천공용 드릴이 관통하는 매개부싱을 상기 유도부싱에 결합시킬 수 있다.Therefore, in order to solve this problem, a stent having an induction bushing fixed to the body portion of the stent is introduced. An intermediate bushing through which the drilling drill penetrates may be coupled to the induction bushing to guide the drilling drill of various sizes into the induction bushing.
일반적으로 상기 매개부싱은 중공 원통 형상으로 이루어지며 그 크기가 매우 작기 때문에 상기 매개부싱을 상기 유도부싱에 결합시키기가 용이하지 않다.Generally, the intermediate bushing has a hollow cylindrical shape and its size is very small, so that the intermediate bushing is not easily coupled to the induction bushing.
따라서, 상기 매개부싱을 유도부싱에 쉽게 결합시킬 수 있도록 상기 매개부싱의 구조변경이 요청된다.Therefore, a structural change of the intermediate bushing is required so that the intermediate bushing can be easily coupled to the induction bushing.
본 발명은 상기한 바와 같은 문제를 해결하기 위해 안출된 것으로, 임플란트를 정밀하게 식립하기 위해 스텐트에 고정된 유도부싱에 매개부싱을 용이하게 결합시킬 수 있는 임플란트 정밀식립용 매개부싱 및 이를 이용한 임플란트 정밀식립 장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the problems as described above, the intermediate bushing for precise implant placement and implant precision using the same that can easily combine the intermediate bushing in the induction bushing fixed to the stent in order to accurately implant the implant The purpose is to provide an implantation device.
