Orthodontic tooth movement and neurotrophins in the rat dento-alveolar complex.
During orthodontic tooth movement, stress is applied on the dento-alveolar complex, initiating a biological response. This response results in the remodelling of the periodontal ligament and the alveolar bone. When a force is placed on a tooth, the periodontal ligament is stretched and compressed …

The Characterization of Osteocyte Apoptosis in a Mouse Model of Orthodontic Tooth Movement
… regularly observed in the alveolar bone during orthodontic tooth movement (OTM). In this study, we wanted to further investigate its occurrence and localization.</p> <p>Method: Sixteen 10-12 week old male CD1 mice were loaded with NiTi springs between the right first maxillary molar and incisor …

The Effect of Corticision on The Rate of Orthodontic Tooth Movement in Rats
<p>Minimal treatment time is a primary goal for orthodontic therapy. Reducing treatment time decreases risk of caries, periodontal disease, root resorption, and increases patient satisfaction. Orthodontic tooth movement (OTM) is a result of bone resorption and apposition; factors influencing the …

CBCT Evaluation of Morphological Changes to Alveolar Bone Due to Orthodontic Tooth Movement
… process is the anatomic factor that limits the orthodontic movement of the mandibular incisors, and awareness of this structural limitation may reduce the risk of potential damage to tooth roots and alveolar bone. A decision regarding the correct placement of the lower incisors will be largely …

Speed of Human Orthodontic Tooth Movement and Reported Pain When Applied Loads are Changed
… experience (intensity and quality) and rates of tooth movement during controlled human tooth movement, specifically where stresses are changed from relatively light (4 kPa) to heavy (52 kPa) and heavy to light. In a split mouth design, maxillary first premolars were extracted, posterior anchorage …

A Study of the Physical Properties of Latex as Related to Orthodontic Tooth Movement
Latex elastics have long been used in orthodontics, and force decay has always been a disadvantage. Reports differ on the load-deflection properties of rubber. Decay in elastic bands has ranged from 8% to 74.9%, depending on test conditions. A study was designed to ascertain (1) whether better …

Association of vitamin D (1,25OHD, 25OHD and vitamin D binding protein) and alkaline phosphatase with orthodontic tooth movement and osteoblast function
… we identified the association of Vitamin D with orthodontic tooth movement and the impact of Vitamin D 1,25OHD and 25OHD forms on osteoblast function. MATERIALS AND METHODS: This study is comprised of two parts; a clinical and a laboratory part. In part I, saliva samples were collected from …

Modulation of RANKL and Osteoprotegerin in Adolescents Using Orthodontic Forces
<p>Orthodontic tooth movement is mediated by interactions between PDL cells and those of the alveolus. One protein--the receptor activator nuclear factor kappa B ligand (RANKL)--is critical for osteoclastogenesis, and osteoprotegerin (OPG) is a decoy ligand that competitively inhibits RANKL. A …

RANKL and Osteoprotegerin Levels in Response to Orthodontic Forces
<p>Orthodontic tooth movement is mediated by interactions between PDL cells and those of the alveolus. One protein—the receptor activator nuclear factor kappa B ligand (RANKL)—is critical for osteoclastogenesis, and osteoprotegerin (OPG) is a decoy ligand that competitively inhibits RANKL. A higher …

The role of autophagy in protecting periodontium integrity, and lipopolysaccharide-induced osteoclast differentiation
… is key to the physiological outcome are orthodontic tooth movement and inflammatory-induced periodontal disease. This thesis aims to investigate the hypothesis that autophagy is involved in bone remodeling during orthodontic tooth movement and periodontal disease. While the stem cells …

Morphological Changes in Alveolar Bone Following Orthodontic Space Closure
… occurring in anterior alveolar bone following orthodontic tooth movement are controversial. Some research has shown that orthodontic tooth movement results in the adaptation of cortical bone; others have shown that it results in dehiscence and fenestrations.</p> <p><em>Purpose: </em>The purpose …

The Effect of Orthodontic Treatment on Sagittal Root Position of the Maxillary Central Incisor
… around the maxillary incisors. The effect of orthodontic tooth movement, specifically changes in inclination, on SRP is of interest in potentially facilitating immediate implant placement. Purpose: The purpose of this study was to use Cone Beam Computed Tomography (CBCT) to evaluate the …

Changes of the Marginal Periodontium as a Result of Labial Tooth Movement in Monkeys
<p>Orthodontic tooth movement was performed on five monkeys (Macaca nemistrina). Oral health was established and exploratory surgery was performed to assess the level of the connective tissue attachment and marginal bone. Measurements of the gingival margin and mucogingival junction were taken and …

Influência clínica e tecidual do diazepam no periodonto de sustentação durante o movimento ortodôntico
… hydrolysis, on the tissue reactions related to orthodontic tooth movement. There is evidence suggesting that cAMP plays an important role as intracellular mediator of bone remodeling induced by mechanical stress. The sample consisted of thirty-six guinea pigs (Cavia porcellus), 9 weeks of age, …

Apoptosis and Osteoblast Differentiation in the Periodontal Lignament in and in vivo Orthodontic Relapse Mouse Model
<p>The phenomenon of orthodontic relapse adds time, cost, and frustration to an orthodontic case. Little is known about the biological basis of relapse. Proper characterizations and quantification of osteoblast differentiation in a mouse model of orthodontic relapse have yet to be demonstrated. It …

Digital Radiographic Analysis of Mineral Density of Adjacent Alveolar Bone in Relation to the Molar Translation Rate After Use of Retromolar Implant Anchorage
… an unique opportunity to measure the rate of orthodontic tooth movement, because implants do not permit any reactive movement from the force. Contrast-corrected digital radiography was utilized to investigate the rate of molar translation related to the mineral density of adjacent alveolar …

Age-related proliferative behavior of mandibular osteoblasts : an in vitro study
… for orthodontists because the performance of an orthodontic tooth movement requires a sufficient remodeling ability of the affected bony tissue. This could be affected by several local and systemic factors which influence the proliferative activity of the osteoblast with increasing age. As the …
