“…Estrogen inhibits osteoblastic differentiation and reinforces the apoptosis of osteoblasts and prevents alveolar resorption. This effect of estrogen decelerates the process of bone remodeling in OTM and decreases the rate of OTM as such [ 39 ].…”

Objectives. Several studies have investigated the effects of different medications on orthodontic tooth movement (OTM). This study assessed the effect of caffeine injection on OTM in rats. Materials and Methods. Thirty-five male Wistar rats were randomly divided into five groups. Their first molars and central incisors were attached with a nickel-titanium closed coil spring with 50 g load. The rats in the three experimental groups received 25, 50, and 75 mg/kg caffeine intraperitoneally for 21 days. The negative control group did not receive any injection and did not undergo orthodontic treatment. The positive control group underwent orthodontic treatment and received 0.9% NaCl (saline) injection. After 21 days, all rats were sacrificed by chloroform inhalation, and the maxilla was resected. The mean number of Howship’s lacunae, blood vessels, osteoclasts, and root resorption lacunae was histologically measured. The bone volume-to-total volume ratio (BV/TV) in maxillary molars was calculated by microcomputed tomography (micro-CT) to quantify bone loss. Results. The amount of OTM and the number of osteoclasts, blood vessels, and Howship’s lacunae significantly increased in rats under caffeine therapy, while the number of root resorption lacunae did not increase. Lower BV/TV in the caffeine groups was in accord with the increased count of osteoclasts. Conclusion. Caffeine injection can significantly increase OTM in rats.

When the duration of orthodontic treatment is shortened, the patient may have a number of benefits, including an increase in the number of dental cavities, root resorption, and gingival irritation, all of which are associated to a higher degree of decalcification. In addition to drugs, magnets, and other therapies, they include surgical methods (corticotomies, piezosurgery), mechanical/physical stimulation techniques (vibration, lasers), and other forms of therapy. These methods, each of which has been validated by extensive research, have been shown to reduce treatment times.

“…1, 25-dhcc and PTH is capable of promoting differentiation of osteoclast and accelerate orthodontic teeth movement by regulating the expression of nuclear factor-κB receptor-activating factor ligand (rank-l) [34][35]. In addition, estrogen acts on estrogen receptor (ERα) to inhibit osteoclast differentiation and stimulates the differentiation of osteoblast [36][37]. The estrogen level in women changes rhythmically as a result of the menstrual cycle: the level is low during the menstrual period when the orthodontic teeth move quickly, therefore, choosing the menstrual period as the re-visits time may effectively shorten the orthodontic duration.…”

Traditional orthodontic treatment is a long process that usually takes 2-3years.Such sophisticated orthodontic equipment as well as long term treatment duration may not only buck the cutting edge trend of "comfort, aesthetics, function and efficiency" in the orthodontic field but contribute to higher risks of complications. Thus, it is pivotal to give top priority to normal dentofacial functions, facial aesthetics as well as short treatment duration under the premise of comfort treatment. Nowadays, numerous adjunctive interventions have been developed by domestic and foreign researchers to accelerate orthodontic teeth movement, which are mainly divided into two categories: surgical intervention and non-surgical intervention. The authors of this thesis have reviewed multiple vital factors accelerating the speed of orthodontic teeth movement to provide readers with wide clinical inspirations so as to optimize the experience of the patient and reduce the incidence of orthodontic complications.
