초록

목적: 하악 제2소구치와 제2대구치를 지대치로 한 지르코니아 고정성 국소의치에서 지대치 간 거리가 파절저항성에 미치는 영향을 조사하였다. 연구 재료 및 방법: Cameleon S zirconia block과 Luxen S2 zirconia block으로 각 재료별 지대치 간 거리를 달리 하여 CS군과 S2군으로 나누어 표기하였으며, 소결된 지르코니아 고정성 국소의치를 임시접착시멘트를 이용하여 에폭시 레진 다이에 합착하였다. 이후, 가공치 교합면에 직경 6 mm 강철구를 위치시켜 로드셀 5.0 kN의 universal testing machine에서 크로스 헤드 속도 1.0 mm/min로 압력을 가하여 파절저항성을 측정하였다. 결과: 지르코니아 고정성 국소의치의 파절저항성은 지대치 간 거리에 큰 영향을 받지 않았다. CS군에서 지대치 간 거리가 15 mm인 경우가 13 mm와 17 mm인 경우보다 파절저항성이 유의하게 높았다(P < 0.05). S2군에서는 파절저항성이 세 군 간에 유의한 차이가 없었다(P > 0.05). 결론: 하악 제2소구치와 제2대구치를 지대치로 한 지르코니아 고정성 국소의치에서 지대치 간 거리는 지르코니아의 종류에 따라 파절저항성에 영향을 줄 수 있다.

Purpose: Zirconia fixed partial dentures with mandibular 2nd premolar and 2nd molar as abutments are fabricated and then the effects of inter-abutment distance on fracture resistance of zirconia fixed partial dentures is studied. Materials and Methods: The materials used in this study are Cameleon S zirconia block and S2 zirconia block, which are divided into CS Group and S2 Group applying different inter-abutment distance for each material, and the sintered zirconia fixed partial denture was luted to the epoxy resin die using a temporary luting cement, and then the fracture resistance was measured by placing a 6 mm diameter hardened steel ball on the occlusal surfaces of the pontics and applying pressure at a cross head speed of 1.0 mm/min on a universal testing machine with a load cell of 5.0 kN. Results: The fracture resistance of zirconia fixed partial dentures is not significantly affected by inter-abutment distance The fracture resistance of zirconia fixed partial dentures in CS Group was significantly higher in 15 mm of inter-abutment distance than in 13 mm and 17 mm of inter-abutment distance (P < 0.05). The fracture resistance of zirconia fixed partial dentures in S2 Group was not significantly different between the three groups (P > 0.05). Conclusion: The fracture resistance of zirconia fixed partial dentures with mandibular 2nd premolar and 2nd molar as abutments does not significantly affected by the inter-abutment distance.
