초록
본 연구에서는 주모형으로부터 인상체를 제거한 후 인상용 코핑이 인상체 내에 남아있는 개방형 트레이 인상법의 이용 시, 인상용 코핑의 연결고정에 따른 효과와 인상 채득 시 사용될 수 있는 수종의 트레이가 주모형의 정확성에 미치는 영향에 대해 비교 연구해 보고자 하였다. 자가중합형 트레이 레진으로 제작한 개인 트레이, 플라스틱 금속 복합 트레이 그리고 폴리카보네이트 기성 트레이 등의 3종류의 트레이가 사용되었고, 각 트레이 마다 인상용 코핑의 연결고정 여부에 따라 두 개의 군으로 나누었다. 이렇게 나누어진 총 6개의 군에서 각 실험군당 10개의 시편을 제작하였다. 임플랜트 유사체와 지대주 사이에 발생한 수직오차의 측정에는 1-screw test법을 이용하였다. 1시편 당 총 6부위를 측정하였고, 3회씩 측정하여 동일한 수치를 나타낼 경우에 기록하여 통계 처리하였다. 인상용 코핑의 연결고정 여부와 상관없이 개인 트레이군, 플라스틱 금속 복합 트레이군 그리고 폴리카보네이트 기성 트레이군 사이에 유의한 차이는 나타나지 않았다. 하지만 개인 트레이, 플라스틱 금속 복합 트레이 그리고 폴리카보네이트 기성 트레이를 이용하여 인상 채득한 경우 패턴 레진으로 연결고정한 군이 비연결고정 군보다 더 정확한 결과를 보여주었다 (p<0.05).
Abstract
The aim of this study was to evaluate the fixation effect by connecting impression copings and to compare the three types of impression trays which were used in open tray impression technique. Experimental groups used 3 types of impression trays which are custom tray, plastic metal combination tray and polycarbonate stock tray. These three groups were subdivided into splinted and non-splinted impression copings group. The total number of experimental groups was six. 10 specimens were made for each group. We used 1-screw test, observing the specimen on which only one side abutment of reference framework was fixated with 20 N㎝. The gap between implant analogue and abutment of the other side was observed by stereo microscope. It was measured at 6 points in each specimen. Measuring value was selected when same result was revealed 3 times. Recorded data were statistically analyzed. Whether impression copings were splinted or not, there was no significant difference among custom tray group, plastic metal combination tray group, and polycarbonate stock tray group. Significant statistical difference in vertical fit discrepancy was found between splinted and non-splinted impression copings group with custom tray, plastic metal combination tray and polycarbonate stock tray (p<0.05).
