Effectiveness and Safety of Minimally Invasive Orthodontic Tooth Movement Acceleration: A Systematic Review and Meta-analysis.
Doctors and patients attempt to accelerate orthodontic tooth movement with a minimally invasive surgery approach. The purpose of this systematic review was to evaluate the evidence of accelerated tooth movement in minimally invasive surgery and the adverse effects from it. A systematic search of the literature was performed in the electronic databases of PubMed, CENTRAL (Cochrane Central Register of Controlled Trials), Embase, Scopus, Web of Science, Science Direct, and Medline and was complemented by a manual search until February 2019. The inclusion criteria were prospective clinical studies of patients treated with a fixed appliance, and the intervention was accelerated orthodontic treatment with minimally invasive surgery. Nineteen articles (538 participants) were included in the review: 9 studies assessed the rate of upper canine movement; 5 considered the treatment time; 1 evaluated the en masse retraction time; and 4 studied adverse effects. We performed a meta-analysis for the rate of canine movement and treatment time and described the results for the adverse effects in a systematic review. The results of the subgroup analysis according to micro-osteoperforation and piezocision were included in the study. No accelerated tooth movement was found in the micro-osteoperforation group. After flapless corticotomy procedures, increased tooth movement rates were identified by weighted mean differences of 0.63 (95%CI = 0.22, 1.03, P = 0.003) and 0.64 (95% CI, -25 to 1.53; P = 0.16) for 1 and 2 mo, respectively. The mean treatment time was 68.42 d (95% CI, -113.19 to -23.65; P = 0.003) less that than for minimally invasive surgery. Moreover, no significant adverse effect was found. Because of the high heterogeneity of the meta-analysis, the results must be validated by additional large-sample multicenter clinical trials. There is not sufficient evidence to support that the single use of micro-osteoperforation could accelerate tooth movement, and there is only low-quality evidence to prove that flapless corticotomy could accelerate tooth movement.
