Description
본 발명은 치과 임플란트용 서지컬 가이드 조성물에 관한 것으로, 픽스츄어 식립을 위한 드릴링 공정의 편의성 및 정확성이 개선을 위한 되는 치아 임플란트용 치과 임플란트용 서지컬 가이드 조성물에 관한 것이다.The present invention relates to a surgical guide composition for dental implants, and to a surgical guide composition for dental implants for improving convenience and accuracy of a drilling process for fixture placement.
일반적으로, 임플란트는 본래의 인체조직이 상실되었을 때 인체조직을 대신할 수 있는 대치물을 의미하지만, 치과에서는 인공으로 만든 치아를 이식하는 것을 말한다. In general, the implant refers to a substitute that can replace the human tissue when the original human tissue is lost, but in dentistry refers to the implantation of artificially made teeth.
즉, 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 other words, it is a procedure that restores the function of teeth by implanting a fixture made of titanium, etc., which does not have a rejection reaction in the human body, in the alveolar bone from which the teeth have escaped, and then fixing the artificial teeth to replace the lost root.
보가 상세히 언급하면, 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. As Beh mentions in detail, in the case of general prostheses or dentures, surrounding teeth and bones are damaged over time, but implants can prevent damage to surrounding dental tissues and can be used stably because there is no secondary cause of caries.
또한, 임플란트는 자연 치아와 실질적으로 동일한 구조를 가지므로 잇몸의 통증 및 이물감이 전혀 없으며, 관리만 잘 하면 반영구적으로 사용할 수 있는 장점이 있다.In addition, since the implant has substantially the same structure as a natural tooth, there is no pain or foreign body feeling in the gums, and it has the advantage of being semi-permanent if well managed.
한편, 임플란트 시술은 드릴을 이용하여 치조골에 천공을 형성하고 상기 천공에 픽스츄어를 식립하여 수행되는데, 천공을 형성하는 드릴링 및 픽스츄어를 식립하는 시술은 환자마다 각각 상이하다. On the other hand, the implant procedure is performed by forming a perforation in the alveolar bone using a drill and placing a fixture in the perforation. Drilling for forming the perforation and the procedure for placing the fixture are different for each patient.
이는 환자의 치아 상태나 임플란트 시술이 필요한 치아의 위치, 환자의 치조골의 상태 등 다양한 요인을 고려하여 임플란트의 식립 위치 및 깊이와 방향을 결정해야 하기 때문이다.This is because it is necessary to determine the implant placement location, depth, and direction in consideration of various factors such as the patient's dental condition, the position of the tooth requiring implant treatment, and the patient's alveolar bone condition.
이처럼, 치조골 천공을 위한 드릴링 작업은 초심자뿐만 아니라 경험자에게도 작업 과정에서 깊이 및 방향을 정확하게 가늠하기가 상당히 어려운 난점이 있다.As such, the drilling operation for perforating the alveolar bone has a very difficult difficulty in accurately estimating the depth and direction in the working process not only for beginners but also for experienced users.
더욱이, 시술 경험이 풍부하지 않은 초보자의 경우 별도의 측정단계 없이 시술 도중 드릴링 될 깊이를 가늠하여 시술한다는 것은 매우 어려운 것이다.Moreover, it is very difficult for beginners who do not have abundant surgical experience to estimate the depth to be drilled during the procedure without a separate measurement step.
또한, 치조골에 천공을 형성시 시술자가 드릴에 힘을 가하여 드릴링 작업을 수행하면서 현재 어느 정도까지 깊이로 드릴링 작업이 이루어졌는지 판단하기가 어려운 문제점이 있었다. In addition, when forming a perforation in the alveolar bone, there is a problem in that it is difficult to determine how deep the drilling operation is currently performed while the operator applies a force to the drill to perform the drilling operation.
더욱이, 일정 깊이 이상으로 드릴이 삽입되면 치조골의 신경을 손상시키는 심각한 문제점이 발생할 수 있다.Moreover, when the drill is inserted to a certain depth or more, a serious problem of damaging the nerve of the alveolar bone may occur.
이와 반대로, 일정한 깊이에 도달하기 전에 드릴링 작업을 종료한 경우에는 드릴된 천공이 깊이가 얕아서 픽스츄어 고정에 과도한 힘이 소요된다. 뿐만 아니라, 천공 주위의 나사산이 손상되거나 픽스츄어가 완벽하게 고정되지 못해 추후 재시술을 하게 되는 문제가 발생하기도 한다.Conversely, if the drilling operation is terminated before reaching a certain depth, the drilled perforation is shallow and requires excessive force to fix the fixture. In addition, the screw thread around the perforation may be damaged or the fixture may not be perfectly fixed, resulting in a problem of subsequent re-treatment.
이에 따라, 천공 작업을 수행할 정확한 위치 및 방향을 파악할 수 있도록 서지컬 가이드(surgical guide)라고 하는 보조 기구를 사용한다.Accordingly, an auxiliary instrument called a surgical guide is used to determine the exact position and direction to perform the drilling operation.
이에 대해 상세히 설명하면, 상기 서지컬 가이드는 성형이 용이한 합성수지 재질로 제조되되 환자의 구강 내부에 고정된 상태에서 천공의 위치에 대응되는 일측에 안내공이 형성된다.In detail, the surgical guide is made of a synthetic resin material that is easy to mold, and a guide hole is formed on one side corresponding to the position of the perforation while being fixed in the patient's oral cavity.
이때, 상기 안내공은 상기 천공 및 픽스츄어의 식립 각도에 대응되어 관통 형성되며 상기 안내공의 내주에 임플란트용 드릴의 외주가 회전지지되어 드릴링 내지 픽스츄어의 식립이 이루어질 수 있다.At this time, the guide hole is formed through the drilling corresponding to the insertion angle of the fixture, and the outer periphery of the implant drill is rotationally supported on the inner periphery of the guide hole, so that drilling or placement of the fixture can be made.
그러나, 종래에는 고속회전되는 드릴에 의해 상기 안내공이 쉽게 열화 변형됨에 따라 상기 천공 형성시 드릴을 실질적으로 안정적으로 지지하지 못하는 문제점이 있었다. However, as the guide hole is easily deteriorated and deformed by the high-speed rotating drill in the related art, there is a problem in that the drill cannot be substantially stably supported when the hole is formed.
이에 따라, 드릴링 된 천공의 방향 및 각도에 대한 정확도가 낮아져 임플란트 시술의 전체적인 완성도를 저하시키는 문제점이 있었다.Accordingly, there was a problem in that the accuracy of the drilling direction and angle of the drilled perforation was lowered, thereby reducing the overall completeness of the implant procedure.
이러한 문제를 해결하고자, 상기 안내공의 내주면에 상기 드릴을 안정적으로 회전지지하면서도 열에 의한 변형이 최소화되는 금속재질로 형성된 슬리브를 체결하여 사용하였다.In order to solve this problem, a sleeve formed of a metal material in which deformation due to heat is minimized while stably rotating and supporting the drill is used on the inner circumferential surface of the guide hole.
그러나, 종래의 상기 슬리브는 상기 서지컬 가이드와 별도의 부재로 이루어짐에 따라 상기 드릴의 회전시 연동 회전되는 문제점이 있었으며 이로 인해, 상기 슬리브의 외주와 상기 안내공의 내주 사이에 발생된 마찰열로 안내공이 변형되고 드릴의 정확한 회전 지지가 불가능한 문제점이 있었다.However, as the conventional sleeve is formed of a separate member from the surgical guide, there is a problem in interlocking rotation during rotation of the drill, which leads to frictional heat generated between the outer periphery of the sleeve and the inner periphery of the guide hole. There was a problem in that the ball was deformed and it was impossible to accurately support the rotation of the drill.
한편, 천공을 형성하는 드릴링 공정은 잇몸 제거, 치조골 위치 설정, 평탄화, 초기홀 형성 및 확장, 나사산 형성 등 다양한 단계로 이루어지며, 각 드릴장치는 일방향으로 회전되며 각 공정에 대응되는 타공을 형성한 후 타방향으로 회전되며 타공으로부터 분리될 수 있다.On the other hand, the drilling process for forming the perforation consists of various steps such as gum removal, alveolar bone positioning, planarization, initial hole formation and expansion, and thread formation. It is then rotated in the other direction and can be separated from the perforation.
이때, 드릴장치의 타방향 회전시 슬리브가 함께 회전되어 안내공으로부터 탈거되므로 상기 드릴장치와 함께 분리된 슬리브를 재결합하는 불필요한 추가 작업이 요구되어 임플란트 시술 시간이 증가되는 문제점이 있었다.At this time, since the sleeve is rotated together and removed from the guide hole when the drill device is rotated in the other direction, unnecessary additional work of recombining the sleeve separated with the drill device is required, thereby increasing the implant operation time.
더욱이, 상기 슬리브의 재결합시 서지컬 가이드의 고정 위치 내지는 슬리브의 결합 방향이 변경되는 경우가 잦아 드릴링 공정의 정확도가 저하되는 문제점이 있었다.

한편, 본 발명의 실시 예들에 따른 조성물로 이루어진 치과 임플란트용 서지컬 가이드는 자외선으로 중합되는 종래기술과는 달리, 가시광선으로 중합되며 보다 구체적으로는 구강 내에서 가시광선을 이용하여 1차 중합이 이루어진 후, 구강 외부에서 가시광선에 의한 2차 중합이 이루어져 제품의 투명도 및 강도를 향상시킬 수 있다On the other hand, the surgical guide for dental implants made of the composition according to the embodiments of the present invention is polymerized with visible light, and more specifically, primary polymerization using visible light in the oral cavity, unlike the prior art that is polymerized with ultraviolet light. After being made, secondary polymerization by visible light is made outside the oral cavity to improve the transparency and strength of the product
이처럼 가시광선을 이용하여 구강 내,외부에서 1, 2차 중합을 하는 이유는 다음과 같다.The reason for the primary and secondary polymerization inside and outside the oral cavity using visible light is as follows.
먼저, 종래기술과 같이 구강 내에서 자외선을 이용하여 중합을 완료하면 단단하게 굳어진 서지컬 가이드가 치아에서 용이하게 분리되지 않는 문제점이 발생하였다.First, as in the prior art, when polymerization is completed using ultraviolet rays in the oral cavity, there is a problem in that the hardened surgical guide is not easily separated from the teeth.
이에 본 발명은 상술한 문제점을 해결하기 위하여 구강 내에서 서지컬 가이드가 약간의 유동성을 갖도록 가시광선을 이용하여 1차 중합한 후, 구강 외부로 분리시켜 2차 중합함으로써 치아에서 분리가 용이하며 투명성 및 강도가 우수한 서지컬 가이드를 제조할 수 있다.Therefore, in order to solve the above-mentioned problems, the present invention performs primary polymerization using visible light so that the surgical guide has some fluidity in the oral cavity, and then separates it to the outside of the oral cavity and secondary polymerization to facilitate separation from teeth and transparency. And it is possible to manufacture a surgical guide excellent in strength.
이하에서는 본 발명의 실시 예들에 따른 치과 임플란트용 서지컬 가이드 조성물의 효과에 대해 상세히 설명한다. Hereinafter, the effect of the surgical guide composition for dental implants according to embodiments of the present invention will be described in detail.
