Resonance Frequency Analysis
Resonance Frequency Analysis
Resonance Frequency Analysis or RFA is used to test the stability of a dental implant. This non-invasive test is based on lateral forces being applied to a dental implant with a vibrating transducer. It has been asserted that RFA corresponds to micro-motion of dental implants.
Unfortunately, implant length and macro-design impact the implant stability quotient (ISQ), micro-motion and insertion torque. Therefore, ISQ measurements and insertion toque have limited value as an indicator of micro motion. Kheur ID 2016
