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 quasi-randomized 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.

A recent systematic review by Long et al. showed that corticotomy is an effective modality to accelerate tooth movement and is relatively safe compared to any other method (Long et al., 2013). Corticotomy is a surgical procedure to accelerate rate of orthodontic tooth movement by causing localized osteopenia and accelerated bone metabolism as a result of controlled surgical damage (Köle, 1959).

    ABSTRACT: Objective: To investigate the effect of Selective Alveolar Decortication (SADc) facilitated orthodontic tooth movement (OTM) on bisphosphonate burdened alveolar bone in a rodent model. Design: OTM was accomplished by protraction of the maxillary right first molars. Four groups were included of which two groups were pre-treated for three months with alendronate sodium (BP+TM+SADc and BP+TM group) and two groups were given saline (TM+SADc and TM group). Selective alveolar decortication surgery was performed on day 1 of appliance insertion. OTM measurements were obtained at 0, 4, and 8 weeks using in-vivo μCT. Tissues were analysed by histology and EPMA. Results: Tooth movement of 0.39mm and 0.75mm in the BP+TM+SADc group at 4 and 8 weeks respectively was achieved with 113% increase in tooth movement compared to BP+TM group at 4 weeks. In comparison, SADc+TM group showed 0.63mm and 2.1mm of tooth movement at 4 weeks and 8 weeks respectively with only 6% increase at 4 weeks and 2% increase at 8 weeks compared to TM group. Severe interproximal and buccal bone loss around the first permanent molar in the BP+TM+SADc group was seen with μCT imaging and histology. Animals in BP+TM+SADc group histologically showed signs of osteonecrotic bone with irregular borders, loss of osteocytes and absence of osteocytic lacunae. Conclusion: This study demonstrated selective alveolar decortication accelerates tooth movement in a bisphosphonate burdened alveolar bone in the short term but the potential of such an invasive injury can have adverse effects.

De plus, la revue systématique de Long, et al. en 2013 souligne l'absence d'études montrant un effet délétère des corticotomies sur le parodonte [14]. Une étude a montré un inconfort post-opératoire similaire entre instruments rotatifs et piézotomes, celui-ci étant limité dans les deux cas à la première semaine post-opératoire [5]. "

    ABSTRACT: Current orthodontic treatments must answer an increasing demand for faster yet as efficient treatments, especially in adult patients. These past years, the amelioration of orthodontic, anesthetic and orthognathic surgery techniques have allowed considerable improvement of orthodontico-surgical treatments and of adult orthodontic treatments. Alveolar corticotomy (an example of such techniques) accelerates orthodontic tooth movements by local modifications of bone metabolism, inducing a transient osteopenia. This osteopenia allows greater tooth movements than conventional techniques. Whereas there is a growing understanding of the underlying biological mechanisms of alveolar corticotomies, there is little data regarding the osteogenic potential of such technique. In the present article, we review the literature pertaining to alveolar corticotomies and their underlying biological mechanisms and present a clinical case underlining the osteogenic potential of the technique. © EDP Sciences, SFODF, 2015.

    • "Many adjunctive modalities are available to accelerate orthodontic tooth movement in humans, such as corticotomy [1–10], distraction osteogenesis [11], mechanical vibration [12], medication with local prostaglandins [13], and low-level laser treatment [14, 15]. Among these interventions, corticotomy is known to be the most effective means to accelerate orthodontic tooth movement [7, 16]. In experiments that used a split-mouth design, with corticotomy performed on one side and the other side serving as the control, the velocity of the tooth movement was accelerated on the corticotomy side [1, 17–19], and the amount of movement doubled over the duration of the experiments [17–20].

    ABSTRACT: Alveolar augmented corticotomy is effective in accelerating orthodontic tooth movement, but the effect only lasts for a relatively short time. Therefore, the purpose of this study was to investigate the underlying biology of the immediate periodontal response to orthodontic tooth movement after a corticotomy with alloplastic bone grafts. The results demonstrated that measurable tooth movement began as early as 3 days after the intervention in beagle dogs. Based on the results and histological findings, augmented corticotomy-facilitated orthodontic tooth movement might enhance the condition of the periodontal tissue and the stability of the outcomes of orthodontic treatment.
