Orthodontic tooth movement Periodontal ligament Precursor cells Mice Proliferation
2010/3/9
Objective: To understand the molecular basis of early orthodontic tooth movement by looking at the expression of KI-67, runt-related transcription factor 2 (Runx2), and tumor necrosis factor ligand su...
An M-CSF Receptor c-Fms Antibody Inhibits Mechanical Stress–Induced Root Resorption during Orthodontic Tooth Movement in Mice
c-Fms Odontoclast Root resorption Mouse Orthodontics
2010/3/5
Objective: To examine the effect of anti-c-Fms antibody on odontoclastogenesis and root resorption in an orthodontic tooth movement mouse model.
Materials and Methods: We used orthodontic tooth mov...
A Numerical Simulation of Orthodontic Tooth Movement Produced by a Canine Retraction Spring
Orthodontics Canine retraction Finite element method
2009/9/14
Tooth movements produced by a canine retraction spring were calculated. Although a gable bend and an anti-rotational bend were incorporated into the spring, the canine tipped and rotated initially. Re...

Long-term orthodontic tooth movement response to short-term force in the rat
Tooth movement Force duration Bone remodeling
2009/1/13
Both the amount of force applied and the duration of the application affect tooth movement. To study the effect of duration, adult male Sprague-Dawley rats were fitted with orthodontic appliances ...
Biomechanical behavior of the periodontium before and after orthodontic tooth movement
Tooth mobility Orthodontic tooth movement Biomechanical property Periodontium Noncontact sensor
2009/1/12
This study was designed to investigate the biomechanical behavior of the periodontium including the periodontal ligament (PDL) in terms of tooth mobility. Tooth mobility was measured in the canine...
The effect of acetaminophen, ibuprofen, and misoprostol on prostaglandin E2 synthesis and the degree and rate of orthodontic tooth movement
Prostaglandin E Tooth movement Inflammation Nonsteroidal anti-inflammatory drugs
2009/1/9
The present study compared the effect of acetaminophen, ibuprofen and misoprostol on PGE2 synthesis and orthodontic tooth movement. Guinea pigs were randomly assigned into one of three test groups or ...
Biological reaction of alveolar bone to orthodontic tooth movement
Orthodontic tooth movement Tissue reaction Bone remodeling Bone modeling
2009/1/4
Direct and indirect resorption are perceived as reactions to an applied force. This is in contrast to the view of orthopedic surgeons, who describe apposition as a reaction to loading of bone. A his...
Orthodontic Tooth Movement in the Prednisolone-Treated Rat
Prednisolone Orthodontic tooth movement Rat TRAP Root resorption
2008/12/29
Adverse effects of corticosteroids on bone metabolism raise concerns as to whether steroid treatment may influence orthodontic movement. This study examined the effect of prednisolone on orthodontic...
The Effect of Chronic Renal Insufficiency on Orthodontic Tooth Movement in Rats
Orthodontic tooth movement Renal insufficiency Rat
2008/12/29
The purpose of this study was to determine the effects of impaired renal function on the amount of orthodontic tooth movement (OTM) in a rat model of renal insufficiency (RI). The animals were div...
Growth Hormone Receptor and IGF-I Receptor Immunoreactivity During Orthodontic Tooth Movement in the Prednisolone-Treated Rat
Bone Corticosteroid Resorption
