초록

목적: Resorbable blasting media (RBM) 표면처리 후 산처리한 티타늄 임플란트와 동일한 표면처리 후 생리식염수에 적신 티타늄 임플란트에서 생리식염수에 적신 경우 초기 골유착에 미치는 영향을 제거회전력 및 표면분석을 통해서 알아보고자 하였다. 연구 재료 및 방법: 대조군은 RBM 표면처리 후 산처리된 임플란트(RBM + HCl)이고, 실험군은 대조군과 동일한 표면처리 후 생리식염수에 2주간 적신 임플란트(RBM + HCl + Sal)이다. 토끼 10마리의 좌우측 경골에 각각 대조군 및 실험군 임플란트를 식립하고, 동시에 식립회전력(ITQ)을 측정하였다. 10일 후 임플란트 식립부위를 노출시켜 제거회전력(RTQ)을 측정하였다. 실험에 사용된 임플란트 시편의 표면분석을 위해 field emission-scanning electron microscopy (FESEM), energy dispersive X-ray Spectroscopy (EDS), 표면거칠기 측정 및 Raman 분광분석을 시행하였다. 결과: RBM 표면처리 및 산처리하여 생리식염수에 적신 티타늄 임플란트에서 대조군에 비해 높은 제거회전력을 나타냈으며, 통계적으로 유의미한 값을 보였다(P = 0.014 < 0.05). 표면거칠기는 실험군에서 더 높은 거칠기를 나타냈다. 결론: 티타늄 임플란트에 RBM 표면처리 및 산처리 후 생리식염수에 적신 것이 생리식염수를 적시지 않은 것 보다 초기 골유착을 향상시키는 것으로 생각된다.

Purpose: The purpose of this study is to investigate the effect of the titanium implant soaked in saline after RBM and acid etched surface treatment on the initial osseointegration by comparing the removal torque and the surface analysis compared to the titanium implant with only RBM and acid etched surface treatment. Materials and Methods: The control group was RBM and acid etched surface treated implants (RBM + HCl), and the test group was implants soaked in saline for 2 weeks after RBM and acid etched surface treatment (RBM + HCl + Sal). The control and test group implants were placed in the left and right tibiae of 10 rabbits, respectively, and at the same time, the insertion torque (ITQ) was measured. After 10 days, the removal torque (RTQ) was measured by exposing the implant site. FE-SEM, EDS, Surface roughness and Raman spectroscopy were performed for the surface analysis of the new implant specimens used in the experiments. Results: There was significant difference in insertion torque and removal torque between control group and experimental group (P = 0.014 < 0.05). Surface roughness of experimental group is higher than control group. Conclusion: Saline soaking after RBM and acid etched surface treatment of titanium implants were positively affect the initial osseointegration as compared to titanium implants with only RBM and acid etched surface treatment.
