Comparison of Effectiveness of Corticotomy-assisted Accelerated Orthodontic Treatment and Conventional Orthodontic Treatment: A Systematic Review

To systematically review the comparative differences in the performance and timeliness of conventional orthodontic treatment with that of corticotomy-assisted accelerated orthodontic treatment.The electronic databases PubMed and Google Scholar were searched from January 2007 to January 2018 in English, with manual searches of reference lists and gray literature. Thirty-six articles were included in the study with inclusion criteria as prospective clinical studies of patients treated with fixed conventional appliance and the intervention was the corticotomy-assisted accelerated orthodontic treatment method.Two reviewers assessed independently the eligibility of the included articles. One investigator abstracted study design information, intervention details, and harms data from all included studies into a standardized evidence table. The accuracy of these data was checked by the second investigator. We resolved any disagreements through discussion with other authors.Different aspects of the corticotomy-assisted accelerated orthodontics treatment method were investigated including risk factors, advantages, and disadvantages as compared to that of conventional orthodontic treatment.There is limited available evidence about effectiveness of corticotomy-assisted accelerated orthodontics. Although the current review indicates that the corticotomy-assisted accelerated orthodontic treatment method can fasten the treatment duration by 2.2-3 folds compared to conventional orthodontic treatment, furthermore, the level of evidence needs well-conducted prospective research with big sample size to draw valid conclusions.Orthodontic treatment is a time-consuming process and due to noncompliance of patients, research has found different methods to accelerate the treatment, thus reducing the total treatment duration. Use of accelerated orthodontic techniques is expected to help clinicians in better treatment decisions for noncompliant patients.
