INVESTIGATION OF THE ANCHORAGE BEHAVIOR OF HEADED REINFORCING BARS USING THE FINITE ELEMENT METHOD By
A headed reinforcing bar is a new type of reinforcement with a T-shaped anchor connected to the end of a reinforcing bar. Conceptually, the bar is usually a tension member or compression one depending on structural engineering applications. The T-shaped anchor, referred to as head in the rest of this report is a relatively stiff steel "plate" in terms of its structural behavior. When embedded i...
متن کاملComparison of Movement of the Upper Dentition According to Anchorage Method: Orthodontic Mini-Implant versus Conventional Anchorage Reinforcement in Class I Malocclusion
Objective. To compare the amounts of anchorage loss in the upper first molar (U6) and of retraction of the upper central incisor (U1) in cases with Class I malocclusion between orthodontic mini-implants (OMIs) and conventional anchorage reinforcements (CARs). Methods. The subjects were 40 female adult patients with Class I malocclusion who were treated with extraction of the first premolars and...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Finite element analysis of dental implant as orthodontic anchorage.
AIM The purpose of this three-dimensional (3D) finite element study was to investigate orthodontic loading simulation on a single endosseous implant and its surrounding osseous structure, to analyze the resultant stresses and to identify the changes in the bone adjacent to the implant following orthodontic loading. MATERIALS AND METHODS Two models were constructed using finite element method ...
متن کاملTemporary Anchorage Device: An Epitome of Anchorage in Orthodontic Treatment
One of the most important phases of oral health is the form and function of the oral mechanism. Recently, pediatric dentists are concerned with the obvious esthetic disabilities and the pathologic implications of the malposed teeth. Interceptive and functional orthodontic treatment is playing a major role in these discrepancies. Anchorage is an important consideration in orthodontics, particula...
