Ex vivo mechanical properties of dental implant bone cement used to rescue initially unstable dental implants: a rabbit study.

Purpose: Dental implant bone cement (DIBC) was developed to rescue unstable implants at the time of placement. The purpose of this study was to compare the mechanical properties of bone-cement-implant interfaces of cemented implants that were unstable initially and bone-implant interfaces of self-threaded implants placed in rabbit femurs after various healing periods. Interfaces and failure modes were also characterized using histology and scanning electron microscopy (SEM).
