Comparison of canine retraction by conventional and corticotomy-facilitated methods: A split mouth clinical study

Adverse Effects of Surgically Accelerated Orthodontic Techniques: A Systematic Review

“…Out of the 39 included studies, 33 were RCTs [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ], from which 17 had a split-mouth study design [ 34 , 37 , 41 , 45 , 48 , 53 , 55 , 56 , 57 , 58 , 59 , 60 , 62 , 64 , 65 , 66 ] and 6 were CCTs [ 22 , 67 , 68 , 69 , ...…”

“…Twelve studies had identified problems with the randomization practices [ 34 , 35 , 36 , 38 , 39 , 40 , 45 , 48 , 49 , 53 , 55 , 65 ]. Twenty-one of the thirty-three included RCTs with a sufficiently stated randomization process [ 37 , 41 , 42 , 43 , 44 , 46 , 47 , 50 , 51 , 52 , 54 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 66 ]. In these trials, randomization was performed with coin tosses, computer-generated random numbers, block randomization, or identical, opaque, sealed envelopes to prevent selection bias.…”

“…In these trials, randomization was performed with coin tosses, computer-generated random numbers, block randomization, or identical, opaque, sealed envelopes to prevent selection bias. The blinding of outcome assessment (detection bias) was possible in 13 trials [ 29 , 37 , 44 , 45 , 46 , 47 , 48 , 58 , 60 , 61 , 62 , 63 , 66 ]; participants and operators (performance bias) could be blinded from each surgical technique in four studies [ 42 , 43 , 57 , 59 ]. Inadequate reporting was identified and was also associated with deviations from intended interventions and measurement of the outcomes.…”

“…From the total of thirty-three included studies, five articles tested corticotomy [ 34 , 35 , 37 , 67 , 71 ], two examined PAOO [ 38 , 39 ], two studied corticision [ 43 , 44 ], eleven investigated piezocision [ 40 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 68 , 70 ], eight evaluated the accelerated tooth movement with the MOPs technique [ 57 , 59 , 60 , 61 , 62 , 63 , 64 , 69 ], and two trials tested lasercision [ 22 , 66 ]. Two studies compared corticotomy with corticotomy combined with bone graft procedures [ 36 , 42 ], one compared corticision with corticotomy [ 45 ], two compared corticotomy with flapless corticotomy using piezotome (piezocision) [ 46 , 47 ], one evaluated MOPs and corticotomy [ 65 ], two tested both MOPs and piezocision [ 56 , 58 ], and one study evaluated corticotomy, piezocision, and corticotomy versus piezocision [ 41 ].…”

“…The majority of the studies that assessed the adverse effects on root length and possible root resorption suggested that there was no evidence of substantial apical root resorption [ 36 , 39 , 40 , 41 , 42 , 44 , 46 , 49 , 50 , 55 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 68 , 71 ]. One trial assessed the amount of root resorption according to CBCT scans after performing corticotomy [ 37 ]. This study reported a statistically significant decrease in canine root resorption on the corticotomy side compared with the control side ( p < 0.05) [Control: Mean ± SD (mm) = 0.53 ± 0.10, 95% CI (0.47, 0.59), corticotomy: Mean ± SD (mm) = 0.24 ± 0.10, 95% CI (0.12, 0.36)].…”
