Do commercial osseodensification systems differ in bone compaction capacity? A volumetric microCT and biomechanical ex vivo assessment

Key Points

• This study aims to evaluate the differences in bone compaction capacity among various osseodensification systems compared to conventional drilling.
• Conducted an ex vivo comparison of three osseodensification systems and conventional drilling.
• Utilized volumetric micro-CT subtraction analysis to assess structural changes in bone specimens.
• Measured biomechanical metrics to evaluate the primary stability of implant sites in low-density bone.
• Identified significant variations in total area and volume of bone compacted by each system.
• Different osseodensification systems showed varying efficiencies in densification compared to conventional methods.
• Quantified the number of bone particles generated during the compaction process.
