Orthodontic tooth movement (OTM) relies on the orchestration of clinical and biologic events that include the application of clinical force followed by a cascade of cellular and molecular responses. Our understanding about OTM today has evolved from, and is largely based on historic studies. However, the advances in bone biology and clinical orthodontics today continue to pave the pathway towards an improved knowledge base, and state of the art therapeutics in OTM. Osteoblasts and osteoclasts have been the primary cells analyzed in OTM...

Vibration as a non-invasive method is currently available for clinical use with the potential to accelerate the rate of tooth movement in orthodontics. The aim of this review was to evaluate the basic science and clinical literature on the effects of vibration on the axial and appendicular skeleton including the craniofacial bone. Vibration as a dynamic load consisting of high oscillatory forces of low magnitude has shown osteogenic and anti-catabolic effects on bone. These effects have been observed in the craniofacial skeleton including the alveolar bone as increases in sutural width and alveolar bone formation...

Asthma is a chronic inflammatory disease, and its prevalence is relatively high among children. Optimal management of asthma often requires long-term pharmacotherapy; however, the effects of these medications on orthodontic treatment is uncertain. We evaluated the effects of the leukotriene LTD4 receptor antagonist montelukast on orthodontic tooth movement in an animal model. Eight mongrel dogs were given montelukast for periods up to 4 weeks. An orthodontic force of 150-200 g was applied to move the second and fourth premolars toward the site of the extracted third premolar...

Orthodontic tooth movement is accompanied by inflammatory responses in the periodontal ligament. Chemical mediators such as interleukin-1β have key roles in nociception around teeth. Such nociceptive inputs to the periodontal ligament continue for several days and potentially induce plastic changes in higher brain regions, including the cerebral cortex. This review summarizes research on orthodontic treatment-induced modulation of neural activities in the central nervous system. Furthermore, we describe our recent findings on the spatiotemporal effects of orthodontic treatment in the somatosensory and insular cortices...

As the number of elderly orthodontic patients increases, the impact of postmenopausal osteoporosis on orthodontic tooth movement (OTM) has attracted a great deal of attention because OTM relies on alveolar bone remodeling. The question of whether OTM causes subsequent alveolar bone loss and is harmful to alveolar bone health under osteoporotic conditions remains to be answered. The present study aimed to clarify the influences of OTM on alveolar bone in osteoporotic rats. OTM was accelerated in ovariectomized (OVX) rats as a result of increased bone resorption in the pressure area...

The connection of a device for the registration of mandibular movements depends on the coupling of the teeth with a paraocclusal adapter. This is normally done by individualizing a prefabricated metal support, either directly on the patient or in the dental laboratory. The goal was to create an individual paraocclusal adapter by means of additive computer-assisted design/computer-assisted manufacturing (CAD/CAM) procedures, and to test it clinically. Starting from intraoral scans of the maxillary and mandibular teeth, an individual paraocclusal adapter was constructed by combining an adapter piece adapted to the tooth and jaw shape with a prefabricated standard part...

Joubert syndrome (JS) is a recessive neurodevelopmental disorder characterized by hypotonia, ataxia, abnormal eye movements, and variable cognitive impairment. It is defined by a distinctive brain malformation known as the "molar tooth sign" on axial MRI. Subsets of affected individuals have malformations such as coloboma, polydactyly, and encephalocele, as well as progressive retinal dystrophy, fibrocystic kidney disease, and liver fibrosis. More than 35 genes have been associated with JS, but in a subset of families the genetic cause remains unknown...

INTRODUCTION: Systematic reviews have shown that powered toothbrushes (PTs) are more effective than manual toothbrushes (MTs), but with only minor effect sizes. Whether PTs are used adequately, however, has not been investigated so far. The aim of the present study was therefore to analyse motion habits with PT in comparison to MT toothbrushes by video observation. MATERIALS AND METHODS: One hundred subjects were enrolled in this observational trial and brushed their teeth in randomised order with a MT and PT while being video-filmed, resulting in 95 analysable sets of recordings...

PURPOSE: The measurement of excursive jaw movements is an important instrument for evaluating the functional condition of the temporomandibular system. Dento-maxillofacial development differs widely within different age, weight or height clusters. Tooth eruption is part of the development of the temporomandibular system. Therefore, the dental developmental stage might reflect temporomandibular development more appropriately. The aim of this study was to investigate whether the dental age is a more suitable parameter for evaluating the mandibular movement range of children in the mixed dentition stage than chronological age...

Early orthodontic tooth movement following regenerative surgery is controversial. In this case, during protraction of the maxillary right first premolar to substitute for the long-term missing maxillary right canine, Bio-Oss and Bio-Gide were used for lateral ridge augmentation at the area of the maxillary right lateral incisor and to cover the denuded surface at the buccal side of the first premolar. Orthodontic tooth movement (OTM) commenced 2 weeks after regenerative surgery. After 8 months, new bone formation was observed on the root surface of the first premolar during implant surgery...

Mutations in the small heat shock protein Hsp27, encoded by the HSPB1 gene, have been shown to cause Charcot Marie Tooth Disease type 2 (CMT-2) or distal hereditary motor neuropathy (dHMN). Protein aggregation and axonal transport deficits have been implicated in the disease. In this study, we conducted analysis of bidirectional movements of mitochondria in primary motor neuron axons expressing wild type and mutant Hsp27. We found significantly slower retrograde transport of mitochondria in Ser135Phe, Pro39Leu and Arg140Gly mutant Hsp27 expressing motor neurons than in wild type Hsp27 neurons, although anterograde movement velocities remained normal...
