Abstract

Purpose : This study was designed to evaluate the influence of implant abutment materials on detorque value and screw joint stability before and after dynamic fatigue test. Materials & Methods : The external hexagonal fixture and three different groups of abutment (titanium abutments, zirconia abutments, and UCLA abutments) were used. The detorque value before loading and after loading (cyclic loading up to $10^5$ cycles) of the abutment screw were measured. Result : 1. There was no significant difference in detorque value before loading among the each group. 2. There was no significant difference in detorque value after loading among the each group. 3. Detorque values before and after cyclic loading in each group were not significantly different. 4. There was no significant difference in loss percentage of removal torque before loading among the each group. 5. There was no significant difference in loss percentage of removal torque after loading among the each group. 6. There was no significant difference in loss percentage of removal torque according to loading among the each group. Conclusion : Short term screw loosening of three types of abutment was not significantly different. When bite force was applied, there was no significant difference in screw loosening between before loading and after loading.

연구목적 : 본 연구는 임플랜트 지대주에 동적하중을 가하기 전, 후의 풀림토크 변화를 측정함으로써 수종의 지대주에 가해진 단기간의 교합력이 임플랜트-지대주의 안정성에 영향을 미치는지를 연구하고자 하였다. 재료및 방법 : 임플랜트 고정체는 외부육각구조를 사용하였고, 티타늄합금 지대주, 지르코니아 지대주, 주조 금합금 지대주인 UCLA plastic abutment를 사용하였다. 초기 풀림회전력을 측정하고, 하중을 $10^5$ 회 가한후, 풀림회전력을 측정하였다. 초기 풀림회전력 상실률, 하중후 풀림회전력 상실률, 동적하중에 의한 풀림회전력 상실률을 계산하였다. 결과 : 초기 풀림회전력, 동적 하중후 풀림회전력, 초기 풀림회전력 상실률, 동적 하중후 풀림회전력 상실률, 동적 하중에 의한 풀림회전력 상실률은 각 지대주간 유의한 차이를 나타내지 않았다. 또한, 각 지대주 내에서 동적 하중 전후의 풀림회전력은 통계적으로 유의한 차이를 나타내지 않았다. 결론 : Titanium, zirconia, UCLA 지대주의 초기 나사풀림은 지대주간 유의한 차이가 없음을 알 수 있었고, 초기의 저작력은 하중전후 나사풀림에 큰 영향을 주지 않는다고 생각된다. 또한, UCLA, zirconia, titanium 지대주의 선택시 초기 나사풀림과 관련하여 특정 종류의 지대주 선택을 기피할 필요는 없다고 생각된다.
