또한,본발명은 매식을 위해 치조골에 형성된 매식홈의 입구를 경고하게 압착 마감하여, 매식후 치조골의 재생이 이루어지면 픽스쳐와 치조골이 거의 일체화 될 수 있는 구성을 제시하여 더욱 안정적이고 견고한 매식상태를 갖도록 함과 동시에 시술 후 외관이 미려하도록 한 개량된 매식구성을 갖는 임플란트 픽스쳐에 관한 것이다. In addition, the present invention warns and closes the entrance of the grooved groove formed in the alveolar bone for the endorsement, suggesting a configuration that can be almost integrated with the fixture and alveolar bone when the alveolar bone is regenerated after the alveolar bone to produce a more stable and solid manner The present invention relates to an implant fixture having an improved implant configuration, which has a beautiful appearance after the procedure.
치아가 빠진 경우 기존에는 틀니를 끼우거나,주변의 치아를 기둥으로 하여 빠진 부분을 금속 등으로 씌우는 시술을 수행하였다.In the case of missing teeth, a conventional method of fitting a denture or using a peripheral tooth as a pillar to cover the missing part with metal was performed.
그러나, 이와 같은 시술과정은 틀니나 브릿지 시술된 인공치아가 음식물을 씹는 힘이 약하고 주변의 치아에 악영향을 끼치는 등의 여러 문제점이 있었다.However, such a procedure has a number of problems, such as a false teeth or bridges artificial teeth chewing food and adversely affects the surrounding teeth.
이에,발전된 치과의료의 한 시술로 임플란트 시술이 등장 하게 되었다. As a result, an implant procedure has emerged as a procedure of advanced dental care.
이와 같은 임플란트 시술은 치조골 인공적인 치아뿌리를 형성하고,이를 이용하여 실제 치아와 흡사하게 제작된 인공치아를 결합하여 환자가 실제치아를 사용하는 효과를 얻게 된다This implant procedure is to create the artificial bone roots of the alveolar bone, by using the combined artificial teeth made similar to the actual teeth to obtain the effect of the patient using the actual teeth.
상기 임플란트 시술과정은 치아가 빠진 치조골에 픽스쳐를 매식 하기위해 드릴 등의 공구를 이용하여 매식 홈을 형성하고, 매식 홈 내부에 픽스쳐를 매식 한 후 픽스쳐에 어버트먼트를 결합하고, 어버트먼트에 인공치아를 결합하여 임플란트 시술이 완료된다. The implantation process is used to form a implantation groove using a tool such as a drill in order to implant the fixture in the alveolar bone missing teeth, and after implanting the fixture inside the implantation groove, combine the abutment with the abutment, The implant procedure is completed by combining artificial teeth.
상기와 같은 임플란트 시술과정에서 치조골에 매식된 픽스쳐는 치아의 뿌리기능을 수행하게 되며, 상기 어버트먼트는 인공치아와 픽스쳐를 일체화하는 연결구성이 된다. 상기 픽스쳐와 어버트먼트는 인공치아를 정위치에 견고히 고정시키기 위한 임플란트 구조물이 되며, 이와 같은 임플란트 구조물은 주로 물리적/화학적 강성이 우수한 티타늄 등의 금속재질로 제작된다. Fixtures embedded in the alveolar bone during the implantation process as described above to perform the root function of the teeth, the abutment is a connection configuration to integrate the artificial teeth and fixtures. The fixture and abutment become an implant structure for firmly fixing the artificial tooth in place, and such an implant structure is mainly made of a metal material such as titanium having excellent physical / chemical stiffness.
한편, 상기 픽스쳐를 치조골에 매식 후 견고하게 자리를 잡을 때까지는 픽스쳐를 매식한 상태에서 몇 개월간 치은을 다시 덮어두거나(서브머지드 타입) 또는 노출된 픽스쳐의 외측을 커버스크류에 의해 마감하게 되며(노출타입), 픽스쳐기 완전히 자 On the other hand, until the fixture is firmly seated in the alveolar bone, the gingival is again covered for several months with the fixture embedded (submerged type) or the outside of the exposed fixture is closed by a cover screw ( Exposed type), fixture fully sleeping
리를 잡으면 치은을 절개하거나, 또는 재차 커버스크류룰 제거하고 인공치아를 성형할 수 있는 지대치 즉, 어버트먼트를 픽스쳐에 안치하고 보철을 씌우게 된다.When the grip is held, the abutment, or abutment, is placed on the fixture, and the prosthesis is cut to remove the gingiva, or to remove the cover screw again and to form an artificial tooth.
상기와 같은 임플란트 시술과정에서 인체의 치조골은 외측의 피질골과 그 내측의 망상골로 이루어져 내측의 약한 망상골을 외측의 단단한 피질골이 보호하는 형태로 되어 있기 때문에, 픽스쳐도 이에 대응하여 외면의 나사부가 피질골에 접촉되는 지점에서 더 조밀한 피치를 갖도록 하고 픽스쳐 자체의 외경이 확장형성 되도록 하여 안정적이고 견고하게 매식하도록 하고 있다. Since the alveolar bone of the human body is made of the outer cortical bone and the inner reticular bone in the implant procedure as described above, the outer cortical bone is protected by the outer cortical bone. At the point of contact with the more dense pitch and the outer diameter of the fixture itself is expanded to form a stable and firmly fed.
그러나, 상기와 같은 픽스쳐의 구성은 매끄러운 나사산으로 구성되어 초기 고정력이 취약하며, 매식 후 또는 임플란트 시술완료 후 상당한 시간이 경과하거나 미세한 시술상의 실수가 발생될 경우,픽스쳐의 나사부가 치조골에서 풀려 재시술을 수행해야 하는 문제점이 발생된다. However, such a fixture is composed of smooth threads, which are weak in the initial fixation force, and if a considerable time passes after the implantation or the completion of the implant procedure, or if a fine procedure mistake occurs, the screw of the fixture is loosened from the alveolar bone and then retreated. The problem arises that you need to do this.
또한,상기와 같은 픽스쳐의 매식은 드릴 등에 의해 치조골 내측으로 매식홈을 형성해야 하기 때문에, 매식홈의 입구주변은 불규칙한 내주형태 및 불량한 미관이 관찰된다. In addition, since the implantation of the fixture as described above should form a grooved groove in the alveolar bone by a drill or the like, irregular inner circumference and poor aesthetic appearance are observed around the entrance of the grooved groove.
이로인해 상기 불규칙한 내주형태에 의해 픽스쳐의 매식 후 또는 임플란트의 시술 Due to this irregular circumferential shape after implantation of the fixture or implantation procedure
후에 픽스쳐의 나사부가 치조골과 유지하는 결합력을 낮추게 되며, 동시에 치은 및 치조골이 복원될 때의 회복력이 떨어지고 미관이 불량한 문제점이 노출된다. Later, the screw portion of the fixture lowers the bonding force that is maintained with the alveolar bone, and at the same time, the recovery force when the gingiva and the alveolar bone are restored is poor and the problem of poor aesthetics is exposed.
또한, 매식 홈 주위의 치조골이 재생되더라도 픽스쳐와 치조골은 나사산에 의해서만 결합되어 있으므로 무리한 힘을 받았을 경우에는 임플란트가 흔들리거나 빠져버리는 심각한 문제가 발생되었다. In addition, even if the alveolar bone around the groove is regenerated, the fixture and the alveolar bone are coupled only by the screw thread, so when the force is applied to the implant caused a serious problem of shaking or falling out.
특히 시술을 끝낸 초기에 치조골 재생이 완전치 않을 경우에는 외력에 따른 즉시하중(인공치가 받는 힘)이 많이 작용하기 때문에 임플란트 전체가 흔들리거나 빠지는 문제가 많이 발생하였으며,이에 재시술을 해야 하는 문제점이 많이 발생되었다. In particular, when the alveolar bone regeneration is not complete at the beginning of the procedure, the immediate load (force applied by the artificial force) acts a lot because of the external force, causing a lot of problems such as the whole implant shaking or falling out. It occurred a lot.
본 발명은 상기 문제점을 해소하기 위해 발명한 것이다. The present invention has been invented to solve the above problems.
