Comparison of removal torque of saline-soaking RBM implants and RBM implants in rabbit tibias / 대한치과보철학회지

ABSTRACT

PURPOSE: The purpose of this study is to investigate the effect of the titanium implant soaked in saline after RBM surface treatment on the initial osseointegration by comparing the removal torque and the surface analysis compared to the titanium implant with only RBM surface treatment. MATERIALS AND METHODS: The control group was RBM surface treated implants (RBM), and the test group was implants soaked in saline for 2 weeks after RBM surface treatment (RBM+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 no significant difference in insertion torque and removal torque between RBM surface treated titanium implants and saline-soaked titanium implants after RBM surface treatment. CONCLUSION: Saline soaking after RBM surface treatment of titanium implants did not positively affect the initial osseointegration as compared to titanium implants with only RBM surface treatment.
