Title The Use of Corticotomies Can Effectively Reduce Treatment Time in Adult Patients
Clinical Question In a young adult patient who needs canines retracted into premolar extraction spaces, is the use of surgically assisted orthodontic techniques to retract the canines more efficient than non-surgically assisted techniques?
Clinical Bottom Line Studies suggest that surgically assisted orthodontics can be used to decrease treatment time by accelerating tooth movement without causing root resorption, loss of tooth vitality, or periodontal problems.

Key resultsA total of 286 patients were involved in the studies. The studies found that there was a reduction in treatment times, which ranged from 30% to 70% compared to control groups. There were no reported complications involving tooth vitality, root resorption, and PDL compromise in any study.

Key results101 patients underwent treatment using different methods to accelerate tooth movement. These methods include low-level laser therapy, corticotomy, electrical current, magnetic fields, and dentoalveolar distraction vs. periodontal distraction. The authors concluded that low-level laser therapy was unable to accelerate tooth movement. Also, the authors concluded that current evidence on electrical current, magnets, dentoalveolar distraction, and periodontal distraction did not indicate accelerated tooth movement. Finally, the authors did conclude that corticotomies are safe and produce accelerated tooth movements.

The Evidence
Validity: Hoogeveen et al searched Pubmed, Embase, Cochrane databases for randomized controlled trials, controlled clinical trials, and case series with 5 or more patients. Two authors individually assessed 45 articles using inclusion criteria, which resulted in 18 eligible studies to be reviewed for the study. Long et al searched PubMed, Embase, Science Citation Index, CENTRAL, and SIGLE for randomized controlled trials and quasi-randomized controlled trials. Two authors independently searched and examined the results. 9 studies met the inclusion criteria.
Applicability The evidence shows that surgically assisted orthodontic techniques, particularly the use of corticotomies, have the potential to accelerate tooth movement with few complications (tooth vitality, periodontal problems, and root resorption) associated with the procedure. Due to differing methodologies, small number of patients per study, and, overall, a lack of comparable data, further research is needed to strengthen the claim that surgically-assisted procedures are more effective.
