Interventions for accelerating orthodontic tooth movement

Abstract

Objective: To evaluate the effectiveness of interventions on accelerating orthodontic tooth movement. Materials and Methods: We searched the databases of PubMed, Embase, Science Citation Index, CENTRAL, and SIGLE from January 1990 to August 2011 for randomized or quasirandomized controlled trials that assessed the effectiveness of interventions on accelerating orthodontic tooth movement. The processes of study search, selection, and quality assessment were conducted independently in duplicate by two review authors. Original outcome data, if possible, underwent statistical pooling by using Review Manager 5. Results: Through a predefined search strategy, we finally included nine eligible studies. Among them, five interventions were studied (ie, low-level laser therapy, corticotomy, electrical current, pulsed electromagnetic fields, and dentoalveolar or periodontal distraction). Six outcomes were evaluated in these studies (ie, accumulative moved distance or movement rate, time required to move tooth to its destination, anchorage loss, periodontal health, pulp vitality, and root resorption). Conclusion: Among the five interventions, corticotomy is effective and safe to accelerate orthodontic tooth movement, low-level laser therapy was unable to accelerate orthodontic tooth movement, current evidence does not reveal whether electrical current and pulsed electromagnetic fields are effective in accelerating orthodontic tooth movement, and dentoalveolar or periodontal distraction is promising in accelerating orthodontic tooth movement but lacks convincing evidence.

Evaluation of Low Intensity Laser on the Rate of Orthodontic Tooth Movement

“…The majority of published research outcomes indicate an increase in the rate of tooth movement after laser therapy compared to controls; however, there are other reports show no difference after laser application, while other investigations concludes that lasers negatively affect tooth velocity, so according to these findings the effect of low level laser on accelerating orthodontic tooth movement is a contra versial subject (4) .…”

Distraction Osteogenesis: Evolution and Contemporary Applications in Orthodontics

“…Past notable attempts to shorten orthodontic treatment time included Corticotomy Assisted Orthodontics (CAO) (Gantes, Rathbun & Anholm, 1990;Chung, Oh & Ko, 2001;Wilcko, Wilcko, Bouquot & Ferguson, 2001;Long, Pyakurel, Wang, Liao, Zhou & Lai, 2013) which is based on the principle of Regional Acceleratory Phenomenon, a term first coined by Frost (1981). Physiologically, this theory proposes that when the bone is decorticated, an exuberant bone remodelling phase occurs in which teeth can be rapidly moved through demineralized bone due to an enhancement in cell-mediated tooth movement.…”

“…To date, several innovative modalities have been reported to accelerate orthodontic tooth movement, including low-level laser therapy, pulsed electromagnetic fields, electrical currents, corticotomy, distraction osteogenesis, and mechanical vibration. Recently Long et al (2013) conducted a critical systematic review of randomized controlled trials to assess the effectiveness of these interventions where in they concluded that both corticotomy and distraction were effective and safe to accelerate orthodontic tooth movement. Kharkhar et al (2010) in their quasirandomized controlled trial to evaluate the best approach to reduce the overall orthodontic treatment time by means of distraction osteogenesis inferred that dentoalveolar distraction was superior to periodontal distraction in all areas of assessment.…”

Highlights on orthodontics literature

“…In an endeavor to elucidate which of the methods would be effective and safe for accelerating orthodontic movement, Chinese researchers developed a systematic review. 5 The authors concluded that low level laser therapy is safe, but incapable of accelerating orthodontic movement, whereas corticotomy is safe and capable of accelerating tooth movement. The other methods need further well designed studies in order to confirm their results.…”
