Comparison of Delayed Implant Placement vs Immediate Implant Placement Using Resonance Frequency Analysis: A Pilot Study on Rabbits
Ten identical implants were equally divided into 2 groups. In the immediate placement (control) group, implants were placed immediately following osteotomy preparation, and in the delayed placement (test) group, implants were placed 2 weeks following osteotomy preparation, in rabbit femurs. Implant stability quotient values for both groups were measured using resonance frequency analysis immediately following placement and at day 40. Results were statistically analyzed and indicate that delayed placement of implants leads to faster rates of osseointegration.
