resonance frequency analysis
Also written as: RFA — Resonance Frequency Analysis
A non-invasive diagnostic method that measures implant stability by analyzing the resonance frequency of a small transducer attached to the implant, expressed as an ISQ value.
Full Definition
Resonance frequency analysis (RFA) is an objective, non-invasive technique used to assess the primary and secondary stability of dental implants throughout the osseointegration process. A small magnetic or electronic transducer (Smartpeg) is attached to the implant or abutment, and a handheld device emits a magnetic pulse to measure the resonance frequency of the implant-bone system. The resulting value is reported on the ISQ scale (1–100). Editors encountering RFA in clinical documentation should confirm it is not conflated with radiographic assessment methods. It is commonly referenced in stability-monitoring protocols and implant research papers.
Usage
Usage note: Spell out in full on first mention; abbreviate as RFA thereafter. Do not conflate with 'resonance imaging' or MRI-related terminology.
In Context
- "Resonance frequency analysis was performed at implant placement and again at the four-week follow-up to track osseointegration progress." — Clinical Research Protocol
- "The RFA reading of 72 ISQ confirmed adequate stability prior to immediate provisionalization." — Patient Progress Note
