목적: 하악 부분 무치악 모형에서 pick-up type 인상용 코핑을 사용한 개방형 인상 채득법과 transfer type 인상용 코핑을 사용한 폐쇄형 인상 채득법, 개방형 인상 채득법에서 pick-up type 인상용 코핑 고정 재료에 따른 인상 채득 정확성을 비교 하고자 하였다. 연구 재료 및 방법: 하악 부분 무치악 모형의 좌측 구치부에 직경 4.5 mm, 길이 11.5 mm의 임플란트 고정체 두 개 식립 후 3D 프린터를 이용하여 개방형 개인 트레이 30개 폐쇄형 개인 트레이 10개를 제작하였다. 제작한 개인 트레이를 이용하여 PN군: 개방형 인상 채득법(non-splint), PG군: 개방형 인상 채득법(splint GC pattern resin), PH군: 개방형 인상 채득법(splint Herifix), TN군: 폐쇄형 인상 채득법으로 나누어 각 군당 10회씩 총 40회의 인상 채득을 진행하였다. 인상채득 후 석고 모형을 제작하여 모델 스캐너로 스캔 후 역설계 프로그램으로 스캔오차를 측정하여 95% 유의수준으로 평가하였다. 결과: 폐쇄형 인상 채득법 TN군이 개방형 인상 채득법 PN군 보다 더 낮은 오차값을 보였다. 개방형 인상 채득법(splint)에 사용된 인상용 코핑 고정 재료 간의 비교 결과에서는 PH군에서 가장 낮은 오차값을 보였으며 PN군, PG군 순으로 정확한 인상 채득 정확성을 보여주었다. 결론: 임플란트 인상 채득 방법이나 인상용 코핑의 연결 고정 유무에 따른 각 군 간의 정확성에 유의한 차이는 없다.

Abstract

Purpose: We investigated the effect of open tray impression using pick-up impression coping and close tray impression using transfer impression coping on the accuracy of impression in edentulous patients on their mandibular parts. the effect of material types of pick-up type impression copings for splinting in open tray impression on the accuracy of impression was also evaluated. Materials and Methods: Two implant fixtures were implanted in parallel in the left molar of the mandibular in the shape of a mandibular partial edentulous model. The 40 individual trays were fabricated using 3D printer. The prepared individual trays were classified into 4 groups (i.e., PN, PG, PH, and TN groups), and a total of 40 impression-takings were conducted. A master cast was connected to a Scan Body. The converted STL file was super-imposed on the scan images of the various groups. Results: The order of standard deviation values decreased as follows: PN (0.2343 ± 0.0844 mm), TN (0.2192 ± 0.0840 mm), indicating that the high accuracy of impression for TN group. In addition, for the comparison results between the material types used in splinting the open tray impression, the PH group showed a relatively lower standard deviation (0.1910 ± 0.1176 mm) than that of the PN group (0.2343 ± 0.0844 mm), PG group (0.2556 ± 0.1082 mm). Conclusion: The acrylic resin synthesized by light-induced polymerization exhibited a higher accuracy of impression taking than that of autopolymerizing acrylic resin. Meanwhile, the accuracy of impression taking was not dependent on the implant impression taking method or the presence of connection/fixation of impression copings.
