Corticotomy-assisted orthodontic treatment

Abstract

Objectives:To systematically review the literature to assess the quality of evidence related to corticotomy-assisted orthodontic treatment (CAOT) as adjunctive treatment in orthodontics.Methods:The study was conducted in the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia between 2013 and 2014. Various electronic databases were searched and abstracts were retrieved. Defined inclusion criteria were then applied to the obtained original articles for further evaluation by 2 examiners independently. The criteria of selection included human, or animal studies, which assessed some aspects of CAOT and/or the biological principles behind it. Case reports and series were excluded. The quality of the studies was evaluated by the methodological score for clinical trials developed.Results:Fourteen articles were retrieved initially, but only 12 articles were finally selected for the study. The CAOT was found to accelerate tooth movement by 2-2.5 folds when compared with conventional orthodontic tooth movement. The CAOT was found safe on periodontal health and exhibits no or little risk of root resorption. A localized turnover of alveolar spongiosa and the absence of a hyalinized zone was the acceptable biological explanation of CAOT. There is no evidence to support that CAOT enhances the movement of ankylosed teeth, closing old extraction sites, post-orthodontic stability, or transverse expansion.Conclusions:Corticotomy-assisted orthodontic treatment should be considered with caution. Long term randomized clinical trials are still needed.

Piezocision as an adjunct to orthodontic treatment of unilateral posterior crossbite

“…Stability was successfully maintained for 18 months, which could also be partially attributed to the piezocision procedure. Although our patient was successfully treated, the amount of evidence proving the effectiveness of piezocision-assisted orthodontics for the correction of posterior crossbite, especially the unilateral ones, remains inadequate 10. The report on the outcome of our case supports using piezocision for the treatment of unilateral cross-bites and bilateral cross-bites of unequal severity.…”

Corticotomy for orthodontic tooth movement

“…There are many terms for corticotomies for orthodontic treatment such as corticotomy-assisted orthodontic treatment (CAOT)3940, AOO67274142, PAOO672741424344454647, selective alveolar decortication (SAD), surgically facilitated orthodontic therapy (SFOT), and corticotomy-facilitated orthodontics (CFO) known as speedy orthodontics. The only difference is that SFOT, AOO, and PAOO involve bone grafting in addition to a corticotomy.…”

Periodontal accelerated osteogenic orthodontics technique for rapid orthodontic tooth movement: A systematic review

“…RAP has been defined as a re-organization activity and physiologic event that happened next to the site of injury, resulting in regional reduction in bone density in the healthy tissue. [20]…”

“…Authors reported that 6–8 months were the time required to treat orthodontic cases with the help of PAOO surgery, which was quite faster than the conventional orthodontic treatment. [20]…”
