Safety Outcomes and Related Tolerability and Biological Responses of Vibration-Assisted Orthodontic Tooth Movement: A Harm-Focused Systematic Review of RCTs. [PDF]

Int J Dent
Vibration‐assisted orthodontic tooth movement (VA‐OTM) has been promoted as an adjunct with the potential to accelerate treatment, yet its safety profile—together with related tolerability and biological responses—remains uncertain. This harm‐focused systematic review of randomized controlled trials (RCTs) primarily appraised clinical safety end points
