Abstract
BackgroundIn recent years, it has been a hot research topic to accelerate orthodontic tooth movement (OTM) through vibration. This review was therefore aimed to systematically evaluate the available evidences on the efficacy of vibrational stimulus to accelerate OTM.MethodsRandomized controlled trials and controlled clinical trials that evaluated the efficacy of vibration on OTM acceleration were searched through electronic and manual search. Two review authors independently conducted the study inclusion, quality assessment and data extraction. The quality of synthesized evidence was assessed according to GRADE system.ResultsEight clinical trials were included in this systematic review. Four studies found that vibration did not enhance the rate of OTM during alignment phase. Two studies revealed that the use of vibratory stimulation accelerated canine retraction. No deleterious effects including pain perceptions and root resorptions were reported.ConclusionsWithin the limitations of this review, weak evidence indicates that vibrational stimulus is effective for accelerating canine retraction but not for alignment. The effects of vibration on pain intensity and root resorption during orthodontic treatment are inconclusive. Future high-quality clinical trials are needed before warranting recommendations to clinical application.
Highlights
In recent years, it has been a hot research topic to accelerate orthodontic tooth movement (OTM) through vibration
Approaches to speed up orthodontic tooth movement (OTM) and the resulting reduction of treatment duration are always desirable to orthodontists and patients
Eligibility criteria The inclusion criteria were as follows: (1) The study should evaluate the effectiveness of vibrational stimulus on OTM; (2) Study design: the study should be randomized controlled trials (RCT) or clinical trials (CCT); (3) Participants: subjects should be systematically healthy patients who require orthodontic treatment; (4) Type of interventions: subjects should be assigned to experimental or control/placebo group based on receiving vibrational stimulus or not; (5) Type of outcomes: indicator of tooth movement velocity and related treatment parameters
Summary
It has been a hot research topic to accelerate orthodontic tooth movement (OTM) through vibration. The prolonged treatment duration could reduce the compliance of patients, and cause numerous adverse effects including white spot lesions, periodontal diseases and external root resorptions [3, 4]. Approaches to speed up orthodontic tooth movement (OTM) and the resulting reduction of treatment duration are always desirable to orthodontists and patients. Numerous surgical and nonsurgical adjunctive procedures to accelerate OTM have been introduced [5,6,7]. Several clinical reports have investigated the effects of vibrations on the rate of tooth movement [14,15,16,17,18,19,20,21,22,23].
