Resonance frequency analysis of osseo-integrated implants for bone conduction in a pediatric population - a novel approach for assessing stability for early loading.

Objectives: The purpose of our study was to directly measure the stability of a bone anchored hearing device (BAHD) abutment using resonance frequency analysis (RFA) in a pediatric population. RFA was used to guide early loading of the abutment following single stage surgery.

Methods: The principle behind RFA is to obtain a numerical value relating to stability.

Evidence for early loading of osseointegrated implants for bone conduction at 4 weeks.

Introduction: The purpose of our study was to directly measure the stability of the abutment using resonance frequency analysis (RFA) and to report on the change in stability over time for implants loaded 4 weeks postoperatively.

Materials And Methods: The principle behind RFA is to obtain a numerical value relating to stability. The Osstell RFA recording device measures the resonance in a magnetic field of a 1 cm commercially manufactured attachment (SmartPeg) that is screwed onto the bone conduction device abutment.
