Abstract:
본 발명은 치과용 임플란트에 관한 것으로, 보다 구체적으로는 생체적합성에 유용한 유전자와 상기 유전자를 효과적으로 전달하기 위한 유전자 전달체가 결합된 유전자-유전자 전달 복합체가 표면에 코팅된 것을 특징으로 하는 치과용 임플란트에 관한 것이다. 본 발명에 의하면, 분자 생물학적인 방법에 의해 임플란트 표면에 유전자를 직접코팅시킴으로서, 임플란트 식립 이후, 상기 유전자가 직접 골아세포 내에서 지속적으로 세포를 증식시킴으로서 임플란트 소재의 생체적합성을 획기적으로 향상 시킬 수 있다. 따라서, 선택적 유전자를 골아세포 등에 직접전달이 가능하기 때문에, 지금까지 임플란트 시술시 동반되었던 염증반응 등의 치주질환과 관련하여 임플란트 시술이 부적합하였던 환자들에게도 다양한 맞춤형 유전자 선별을 통하여, 보다 폭넓고 성공적인 시술이 가능하다.
