| Title |
Resonance Frequency Analysis at Implant Placement is not Able to Predict Implant Failure in Immediately Loaded Implants |
| Clinical Question |
In adults, can resonance frequency analysis at the time of implant placement forecast implant failure in immediate loaded implants? |
| Clinical Bottom Line |
Resonance frequency analysis taken at time of surgery is not sufficient to identify risk of failure in immediately loaded implants. This is well supported by a systematic review and meta analysis. |

| #1) 22720282 | Atieh/2012 | 2236 immediately load implants in 15 studies | Systematic Review/Meta-Analysis | | Key results | “The sensitivity of RFA in predicting failure of immediately loaded implants was 0.38 (95% confidence interval [CI]: 0.22 to 0.56), the specificity was 0.73 (95% CI: 0.71 to 0.75), and the diagnostic odds ratio was 2.10 (95% CI: 0.79 to 5.57).” RFA is not accurate in identifying failure risk in immediately loaded implants when taken at the time of placement. | | #2) 23113597 | Atieh/2012 | 28 immediately loaded molar implants | Case series | | Key results | RAF at the time of surgery is not a significant predictor of implant failure in immediate loaded molar implants in the posterior mandible. The Area under the curve for RAF taken at surgery was 0.45 with non-significant p-value of 0.70. RAF measurements are more accurate when taken 8 weeks after implant placement. | | #3) 17066633 | Al-Nawas/2006 | Beagle dogs | Animal study | | Key results | In beagle dogs RAF and insertion torque were not predictive of implant loss when during the loading phase. Higher IQU values were present in successful implants. | |

Comments on
The Evidence |
The systematic review/meta analysis provides a high level of evidence to suggest RAF at time of placement is not able to predict failure of immediately loaded implants. The decision to immediately load implants should use radiographic interpretation, insertion torque, and clinical experience to help overcome low sensitivity of RFA. There is some data to suggest that RAF becomes more significant 8 weeks after implant placement. |
| Applicability |
RAF machines are relatively inexpensive, do not cause harm to the patient, but one time measurements have a limited ability to predict implant failure in immediately loaded implants. This limits there application in a private practice. |
