We describe our experience with conservative condylectomy for the correction of facial asymmetry in five patients with osteochondroma of the mandibular condyle. All five patients presented with malocclusion and facial asymmetry, which are common clinical findings of osteochondroma involving the mandibular condyle. We performed conservative condylectomy without additional orthognathic surgery fo...

Mandibular fractures are among the most common facial injuries. This case report demonstrates the efficacy of simultaneous usage of miniscrews and direct bonding techniques without open reduction in an extensive traumatized patient. A 25-year-old girl with multiple injuries in the head and facial region 1 month after a plane crash accident was referred to manage the mandibular fractures. Due to...

been used to direct the eruption of an impacted tooth by applying force to an attachment on the tooth. One such attachment is the versatile “loop-button” or bondable eyelet, a 1mm helix of round wire welded or brazed to a small bondable base. The Monkey Hook* is a simple auxiliary with an open loop on each end for the attachment of intraoral elastics or elastomeric chain, or for connecting to a...

We attempt to give a bird’s eye view of the physical mechanisms leading to anomalous relaxation, and the relation of this phenomenon with anomalous diffusion and transport. Whereas in some cases these two notions are indeed deeply related, this needs not to be the case. We review several models for stretched exponential relaxation (diffusion in traps, broad distribution of relaxation times, two...

INTRODUCTION Space closure is one of the most challenging processes in Orthodontics and requires a solid comprehension of biomechanics in order to avoid undesirable side effects. Understanding the biomechanical basis of space closure better enables clinicians to determine anchorage and treatment options. In spite of the variety of appliance designs, space closure can be performed by means of fr...

Introduction. Numerous devices have been introduced for correction of Class III malocclusion and maxillary deficiency. Aim. To assess the dentoskeletal effects of miniplates combined with Class III traction in treating Cl III malocclusion and maxillary deficiency in growing patients. Methods. This case describes the treatment of a maxillary-deficient 11-year-old boy by using miniplates. The pat...

UNLABELLED The present report describes the application of a miniplate in the hard palate of a 36-year-old patient with a large anterior maxillary defect. The combination of orthodontic elastics with a titanium miniplate improved the stability of the prefabricated prosthesis. This structure retained the ointment gauze covering the wounds and maintained the facial contour. In addition, contractu...

the aim of this research is to calculate the elastic constants and bulk modulus of cu-20 wt% ni random nanoalloy. the molecular dynamics simulation technique was used to calculate the mechanical properties in npt ensemble. the interaction between atoms as well as cohesive energy in the nanoalloy modeled systems was calculated by morse et al. two body potential. also the temperature of the syste...

In this study the effect of thermal stress on the torsional buckling of double walled carbon nanotubes is investigated. Moreover based on nonlocal continuum mechanic the buckling governing equations are obtained and equilibrium of Equations is generalized to double wall nanotubes. Also in this study the elastic medium, small scale effect and van der Walls force are considered. Also for simulati...
