Introduction: The purpose of this study was to evaluate whether the external application of pulsed electromagnetic fields (PEMF’s) could enhance the amount of orthodontic tooth movement in young

Millions of people worldwide have orthodontic therapy for the treatment of dental malocclusions, craniofacial disorders, and simply to improve their appearance. However, orthodontic treatment has several major problems, including the long time braces must be worn, the pain involved during treatment, and the need to wear retainers to prevent relapse. Orthodontics could be improved. Understanding...

Orthodontic forces deform the extracellular matrix and activate cells of the paradental tissues, facilitating tooth movement. Discoveries in mechanobiology have illuminated sequential cellular and molecular events, such as signal generation and transduction, cytoskeletal re-organization, gene expression, differentiation, proliferation, synthesis and secretion of specific products, and apoptosis...

Figure 2. Extrusion after 1 week. A subgingivally fractured incisor presents a restorative challenge. Orthodontic eruption is a good alternative to crown lengthening for restoring the biological width, maintaining the alveolar bone, and restoring esthetics. The technique requires a hook to serve as the attachment system, fixed to the fractured tooth root, and an anchorage bar to allow movement ...

Introduction Eruption of deciduous teeth remains a rather sophisticated process. This paper gives a general overview of the process and explores on its implications. Overview Eruption of deciduous teeth may be divided into preeruptive tooth movement, eruptive tooth movement and post-occlusal tooth movement. Emergence of deciduous teeth is usually accompanied by teething symptoms. Mechanisms for...

Corticotomy-assisted orthodontic treatment is an established and efficient orthodontic technique that has recently been studied in a number of publications. It has gradually gained popularity as an adjunct treatment option for the orthodontic treatment of adults. It involves selective alveolar decortication in the form of decortication lines and dots performed around the teeth that are to be mo...

OBJECTIVES Various methods have been introduced for evaluation of tooth movement in orthodontics. The challenge is to adopt the most accurate and most beneficial method for patients. This study was designed to introduce analysis of digital photographs with AutoCAD software as a method to evaluate tooth movement and assess the reliability of this method. MATERIALS AND METHODS Eighteen patients...

Clodronate, a non-N-containing bisphosphonate, strongly inhibits bone resorption and also has anti-inflammatory properties. The purpose of this study was to examine the effect of the local administration of clodronate on orthodontic tooth movement. Both the right and left upper first molars of 26 7-week-old male Wistar rats were moved buccally with a standardized expansion spring. Clodronate so...

Newton’s third law of motion states that whenever a force is applied an equal and opposite force occurs in the opposite direction of applied force. Orthodontic tooth movement (OTM) being a biological phenomenon; sound knowledge of biomechanics is required. Sliding mechanics is a common approach in orthodontics to achieve tooth movement for closure and gaining of space.1,2 Sliding mechanics invo...
