Physiologic healing after implant placement varies from patient to patient and site to site. Surgeons must find balance between mechanical stability and avoiding excessive trauma to alveolar bone, especially the cortical bone found at the alveolar crest. The two measures of quantifying primary stability are insertion torque volume (ITV) and resonance frequency analysis (RFA). Implant stability quotient or ISQ is a value used to determine stability via RFA.

I was curious about the correlation between immediate insertion torque (IT) and ISQ and wanted to study it in my practice. This is a study I conducted and it was published in IJPRD recently. The study protocol and findings are posted here for you to read and comment on.

Thanks,

Barry Levin

#### About Us

We help clinicians improve patients' comfort and confidence by reducing treatment time and managing patients with risk factors. Osstell tells you when an implant is ready for loading. It helps you to objectively and non-invasively determine implant stability and to assess the progress of osseointegration – without jeopardizing the healing process. Osstell uses Resonance Frequency Analysis (RFA) to determine implant stability and osseointegration. The result is presented as an ISQ (Implant Stability Quotient) value of 1-100.
