치아 임플란트란 치아의 결손이 있는 부위나 치아를 뽑은 자리의 턱뼈에 티타늄 등의 생체 적합성을 가진 소재로 제조된 임플란트 본체(픽스츄어)를 심어서 자연치의 기능을 회복시켜주는 치과 치료법이다. 오랫동안 치아의 이탈, 염증 등에 의해 픽스츄어가 식립될 치조골이 충분한 두께(양)를 가지지 못하는 경우, 식립된 픽스츄어가 충분히 지지될 수 없고 픽스츄어와 신경의 인접으로 인한 통증이 발생할 수 있으므로, 픽스츄어의 이식 전이나 또는 동시에 결손된 치조골 부위에 골이식재(Bone graft materials)를 이식하여 골조직 재생을 도모하는 골유도재생술(Guided bone regeneration, GBR)을 시행한다. 상기 골유도재생술의 시술은 시술부위의 잇몸을 절개하고 벌려 치조골을 노출한 다음, 결손된 치조골 부위에 골이식재를 이식하고 의료용 차폐막이 골이식재를 감싸도록 한 후, 절개된 잇몸을 늘여 봉합하는 방식으로 수행하게 된다. 상기 의료용 차페막은 하기의 특허문헌에 기재된 바와 같이, 골이식재를 커버하여 골이식재의 유동을 방지하고 외부압력으로부터의 보호하여 골이식재를 안정화하고, 잇몸과 골이식재를 차단하여 잇몸이 재생중인 뼈 부분에 침투하는 것을 방지한다.A dental implant is a dental treatment that restores the function of natural teeth by implanting an implant body (fixture) made of a biocompatible material such as titanium on the jawbone of a tooth defect or a tooth extraction area. If the alveolar bone to which the fixture is to be implanted due to tooth detachment or inflammation for a long time does not have a sufficient thickness (quantity), the implanted fixture cannot be sufficiently supported and pain may occur due to the proximity of the fixture and the nerve. Guided bone regeneration (GBR) is performed to promote bone tissue regeneration by implanting bone graft materials into the missing alveolar bone before or at the same time. The procedure of bone guided regeneration is to cut the gum at the surgical site and open the alveolar bone to expose the alveolar bone, and then implant the bone graft material into the defective alveolar bone area and allow the medical shield to wrap the bone graft material, and then suture the stretched gum. Will be performed. As described in the patent document below, the medical shielding film covers the bone graft material, prevents the flow of the bone graft material and protects it from external pressure to stabilize the bone graft material, and blocks the gum and the bone graft material to prevent the bone from being regenerated.

공개특허 제10-2014-0003942호(2014. 01. 10. 공개) "연조직 또는 골조직 성장이 우수한 의료용 차폐막"Patent Publication No. 10-2014-0003942 (published Jan. 10, 2014) "Medical shielding membrane with excellent soft tissue or bone tissue growth"
하지만, 골유도재생술에서 치조골의 결손된 부분이 많아 많은 양의 골이식재를 이식하는 경우, 잇몸을 늘려 의료용 차폐막을 감싸도록 봉합하더라도 잇몸이 늘어나는 것에는 한계가 있어, 잇몸의 봉합부위에서 벌어지는 부분이 발생하거나 봉합시 처음부터 절개부위가 벌어진 상태로 봉합할 수밖에 없는 상황이 발생할 수 있는데, 종래의 의료용 차폐막은 그 전체에 걸쳐 혈액 등이 통과할 수 있는 미세천공이 형성되어 있어, 잇몸의 봉합부위가 벌어지면 이 부분으로 침투한 타액 등의 이물질이 상기 의료용 차폐막의 미세천공을 통해 재생중인 뼈 부분에 침투하여, 재생중인 뼈 부분을 오염시키거나, 타액으로 인해 이식골의 소실을 발생시키거나 감염을 일으켜 치조골의 재생을 방해하는 문제가 있다. 또한, 공개특허 제10-2012-0074087호 "치조골의 골유도 재생술용 천공형 차폐막"이 개발됐지만, 이차폐막은 어떠한 크기의 천공도 존재하지 않은 밀폐부가 미세천공이 형성되어 있는 천공부로 전체면이 둘러싸여 있지 않아 상기 차폐막이 골이식술에 사용되었을 때 연조직 봉합부위가 벌어져 밀폐부가 노출되면 천공부로 밀폐부 전체가 둘러싸여 있지 않으므로, 천공부로 둘러싸인 부위는 천공부를 덮고 있는 연조직이 이 미세천공을 통해 하부조직과 연결되어 결합되므로서 촘촘한 방어벽을 만들고, 미세천공 사이의 아주 좁은 면적의 차폐막 표면과 연조직이 아주 긴밀하게 접촉하므로서 이 부위를 통한 이물질이나 기타 오염물질의 유입을 차단시키는 효과를 발휘하나, 천공부로 둘러싸여 있지 않은 부위는 연조직이 덮고 있어도 상기와 같은 차단효과가 전혀 없으므로 이 부위를 통해 오염물질이 침투하여 감염을 발생시키거나 이식골이 빠져나가는 일이 발생하여 치조골의 재생을 방해하는 문제가 있다. 즉, 종래의 차폐막은 미세천공이 형성되어 있는 천공부로 완전히 둘러싸인 밀폐부가 없으므로 봉합부위가 벌어졌을 때 골이식부위를 완벽하게 보존할 방법이 없는 문제가 있다.However, in the bone regeneration procedure, when there is a large portion of alveolar bone defects and a large amount of bone graft material is implanted, there is a limit to the extension of the gums even if the gums are stretched to cover the medical shield, so that the part of the gum sutures is limited. When it occurs or sutures, there may be a situation in which the incision is opened in a state where the incision is opened from the beginning, but the conventional medical shielding membrane has micropores through which blood, etc. can pass, and the suture region of the gum is formed. When opened, foreign matter such as saliva that penetrated into this part penetrates the regenerated bone through the microperforation of the medical shielding membrane, and contaminates the regenerated bone part, or the saliva causes loss of the graft or infection. There is a problem that interferes with the regeneration of the alveolar bone. In addition, Patent Publication No. 10-2012-0074087 "Perforated shielding membrane for osteoinductive regeneration of the alveolar bone" was developed, but the secondary shielding membrane is a perforated part in which the sealing portion in which no perforation of any size exists is formed with microperforations. When the shielding membrane is used for bone graft, when the soft tissue suture is opened and the sealing part is exposed, the entire sealing part is not surrounded by the perforation part. Therefore, the soft tissue covering the perforation part covers the microperforation. It connects to the lower tissue and connects to create a tight barrier. The close contact between the surface of the membrane and the soft tissue between the micropore and the very soft tissue blocks the inflow of foreign substances or other contaminants. , The area that is not surrounded by the perforation part has the same blocking effect even if the soft tissue is covered Since there is no contaminant penetrates through this site to cause an infection or the graft bones to fall out, there is a problem of preventing the regeneration of the alveolar bone. That is, the conventional shielding film has a problem that there is no method of completely preserving the bone graft site when the suture is opened because there is no sealing part completely surrounded by the perforation in which the microperforation is formed.

The very narrow area between the micropores is in close contact with the soft tissue to block the influx of contaminants and prevent the loss of the transplanted bone tissue. Therefore, the purpose is to provide a surgical shield that can be successful bone graft.

또한, 본 발명은 밀폐부 하부의 이식된 조직을 감염이나 오염으로부터 차단할 수 있는 기능으로 인해 치조골 재싱술뿐만 아니라 부착치은 확대술에도 사용하여 쉽게 부착치은을 확대할 수 있는 효과가 있다. 즉, 부착치은을 재생시키기 위해서는 기존에는 구강내 다른 부위에서 조직을 떼어내 부착치은 재생이 필요한 부위에 이식해야하는데, 이 기존 방법은 구강 내에 조직을 떼어내는 2차적인 수술부위가 발생하게 되고, 또한 떼어낼 수 있는 조직도 한계가 있으며 이식한 조직이 잘 생착되도록 기존 베이스 조직에 잘 밀착시켜야 하는 어려운 부분이 있는데 이 차폐막을 쓰게 되면 구강내에서 별도의 조직을 떼어낼 필요 없이 부착치은 재생술이 필요한 부위의 부착치은상에 절개부를 형성하고 치은을 박리한 후 Collar tape와 같은 제품화된 것을 위치시킨 후 이 차폐막으로 덮고 잇몸 늘리는 작업 없이 최소한 천공부만이라도 잇몸이 덮도록 봉합하게 되면 잇몸 조직은 약간 벌어진 상태로 봉합이 일어나고 밀폐부 밑에 위치한 조직이 부착치은으로 형성되게 된다.In addition, the present invention has an effect that can be easily enlarged by using the attached gingival enlargement as well as alveolar bone graft surgery due to the ability to block the implanted tissue in the lower portion of the sealing portion from infection or contamination. That is, in order to regenerate the attached gingiva, the tissue must be removed from other parts of the oral cavity and transplanted to the site requiring regeneration of the attached gingiva. This conventional method causes a secondary surgical site to remove the tissue from the oral cavity. In addition, there is a limit to the detachable tissue and there is a difficult part to adhere well to the existing base tissue so that the transplanted tissue adheres well. After making an incision on the gingiva and peeling the gingival, placing a commercialized product such as a collar tape, covering it with a shielding membrane and suturing the gum to cover at least the perforated part without stretching the gums. Sutures and tissues underneath the seal are formed into adherent gingiva The.
