Evaluation of corticotomy-facilitated orthodontics and piezocision in rapid canine retraction

Efficacy of piezocision on accelerating orthodontic tooth movement: A systematic review

“…In total, 4 studies were included in this review. [14][15][16][17] The kappa score regarding the agreement level was .94, which could serve as the indicator of low interexaminer bias. 20 The details of study inclusion are shown in the PRISMA flow diagram (Figure 1).…”

“…Among the four studies, two were CCTs 14,15 and the other two were RCTs. 16,17 A total of 67 patients were enrolled in this review, with the sample size of individual studies ranging from 10 to 24.…”

“…In terms of types of tooth movement, the two CCTs 14,15 used canine retraction as the study model while the two RCTs 16,17 focused on the alignment phase and entire treatment, respectively. One study 15 compared the efficacy between piezocision and conventional corticotomy. Sample size calculation was adopted in the 2 RCTs.…”

“…Of the four studies, three were identified as having an unclear risk of bias, [15][16][17] and the other one was assessed as high risk of bias. 14 Randomization was performed in two RCTs 16,17 and partially in one CCT.…”

“…12 Moreover, several clinical reports have determined the effectiveness of piezocision in accelerating OTM. [13][14][15][16][17] However, the methodological heterogeneity and inconclusive results of these studies could bias the evidence and mislead clinical practice. Therefore, a critical systematic review addressing this topic would be beneficial to clinicians.…”
