Interview - 김차동 국가과학기술위원회 상임위원
이은정,Lee, Eun-Jeong 한국과학기술단체총연합회 2011 과학과 기술 Vol.509 No.-
국가과학기술위원회(국과위)가 출범한 지 6개월이 지났다. 현 정부 출범 후 과학기술부가 교육과학기술부(교과부)로 통합되면서 '과학정책이 실종됐다'는 비판을 받기도 했는데 국과위가 출범해 정부 전체의 연구개발을 총지휘하기로 조직이 바뀐 것이다. 그동안 문제가 됐던 과학정책에서의 '컨트롤 타워' 역할을 국과위가 잘해낼 수 있을지, 김차동 상임위원을 만나 소회와 앞으로의 계획을 들어봤다.

Purpose: The objective of this systematic review was to obtain the comprehensive survival rates of short implants. Then it was examined that whether treatment using short implants has favorable results. Methods: A MEDLINE search was performed, the data obtained from many articles about length, diameter, site of placement, surface treatment and prosthetic design were analyzed. Results and discussion: The data obtained from many articles were analyzed, and it was found that the survival rate of short implants was 95.87%, short implants has similar outcomes to those reported for standard implants. On the other hand, in the comparison the survival rate of 3 groups divided by the diameter of implants under 4 mm, 4-5 mm, and above 5 mm, a statistically significant difference was detected in under 4mm group. In implant group with 6-7 mm length, a group with 5-6 mm diameter has survival rate of 97.01%, groups with 3.1-4.8 mm diameter has survival rate of 92.96%, which was statistically significantly different. In the result of surface feature, the roughed surface groups of short implant showed a higher survival rate by approximately 6.3% than machined surface group. In the result of prosthetic design, survival rate of short implant was considerably lower for the single implant crown group (94.3%) than splinting group (99.4%).
