ISQ – is a number (based on a scale from 1 to 100) which measures the lateral stability of the dental implant and thereby indirectly the degree of osseointegration achieved through linear mapping of resonance frequency analysis (RFA). While the actual values are expressed in Hertz, the ISQ number has been developed to facilitate communication regarding implant micromobility through a more user-friendly scale using implant-specific SmartPegs. (ISQ x 1,000 = RFA in Hz) nylon, or teflon-coated instrument tips are recommended for titanium surfaces.
