Incidence of orthodontic brackets detachment during orthodontic treatment: A systematic review

Abstract

Objectives:To evaluate the incidence of orthodontic brackets detachment during orthodontic treatment.Methods:Using electronic databases; eligible studies up to January 2018 were retrieved, independently reviewed, and screened. The Coleman Methodology Scoring System (CMS) and Cochrane Collaboration’s tool were used to assess quality and risk of bias in the included studies.Results:Of the seventeen studies included in the final synthesis, thirteen were categorized as randomized clinical trials (RCTs), one prospective cohort and retrospective survey each, whereas two studies could not be categorized. The number of patients in the selected studies ranged between 19 and 153; the mean age was between 10.5 to 38.7 years, and male to female ratio was 353:495. Almost all studies had a high risk of bias, and more than half of the studies had CMS score of 70 or above. The numbers of brackets examined in the studies ranged between 361 and 3336. The incidence of brackets detachment ranged from 0.6 to 28.3%.Conclusions:The incidence of brackets detachment during orthodontic treatment is high.

Relative Assessment of Bonding Strength of Orthodontic Adhesives

“…The results attained were in accordance to those evaluated by Ryou (Ryou et al, 2008). However, contradictory results were shown by to Northrup et al and Lee et al where they reported an ARI score of 3 in 90% and 40% respectively (Almosa and Zafar, 2018;Soonthodu et al, 2018). The difference in the ARI scores could be due to the in luence of other variables such as study design, bracket base, and enamel pre-treatment.…”

A Retrospective Clinical Audit of Bracket Failure among Patients Undergoing Orthodontic Therapy

“…There are a number of steps involved during the bonding of attachments on the tooth surface. Overall, bonding failure was found to be as low as 0.6% and as high as 28% [ 10 , 17 – 23 ]. In general, a bracket failure rate below 10% has been suggested to be clinically acceptable.…”

Comparison of frictional coefficient and surface roughness between three different active self-ligating brackets: An experimental in vitro study

“…Orthodontic treatment using fixed appliances is based on the specific forces that is applied to the teeth through the attachment of brackets. [1] Extreme friction forces will impede the teeth movement and detract the efficacy of the appliances. [2] Friction is affected by biological factor-such as saliva, debris, and biodegradation of the appliance's components that has been used-and physical factor as the using of brackets, archwires, and ligations.…”
