Efficacy of implant removal procedures. Primary efficacy (most stringent definition): Implant successfully removed without implant breakage, and additionally for device procedures, without scalpel or forceps, P < 0.0001
Secondary efficacy: Implant successfully removed yet allowing implant breakage, and additionally for device procedures, without scalpel or forceps, P < 0.0001
Tertiary efficacy: Implant successfully removed yet allowing implant breakage, and additionally for device procedures, without the use of a scalpel, P = 0.017. Note: the standard procedure was 100% effective on all three efficacy measures.
