Successful treatment of anterior openbite malocclusion is considered one of the most challenging areas in orthodontics. This study was designed to evaluate the treatment effects of the multiloop edgewise archwire therapy in openbite correction and to investigate the stability of correction during a 2-year follow-up period. The subjects consisted of 55 white patients who presented with anterior ...

This research is aimed at developing the sandwich structure with a hybrid composite facesheet and investigate its mechanical properties (tensile, edgewise compression, flexural). The combination of renewable synthetic materials appears to reduce weight, cost, environmental impact compared pure materials. facesheets were fabricated different ratios stacking sequence flax glass fibers. nonhybrid ...

This paper focuses on unsupervised modeling of morphological families, collectively comprising a forest over the language vocabulary. This formulation enables us to capture edgewise properties reflecting single-step morphological derivations, along with global distributional properties of the entire forest. These global properties constrain the size of the affix set and encourage formation of t...

An adult patient with proclination and spacing was performed orthodontic treatment combined with corticotomy and the burstone three piece intrusive arch who desired a shortened treatment period. The patient had Angle's Class I malocclusion with flaring of the maxillary and mandibular incisors. Pre adjusted edgewise appliance (MBT prescription) was fixed to the maxillary and mandibular teeth. Th...

Overeruption of maxillary molars due loss of opposing teeth creates occlusal and functional interferences. Before reconstruction can be initiated, intrusion of overerupted molars becomes essential. This report illustrates treatment of overerupted maxillary premolar and molar via direct use of miniscrew anchorage. A 24-year old female had lost first and second left mandibular molars due to pulpa...

Due to their size, small rotorcraft are vulnerable to external flow disturbances that are challenging to flight stability and control. This paper describes preliminary results from using onboard flow measurements to augment inertial sensors for attitude control. We derive a dynamic model that captures the aerodynamic effects of wind on a single degree-of-freedom tandem-rotor test stand. A pair ...

background: the extraction of teeth for orthodontic purpose has always been a controversial subject in the speciality. the aesthetics impact of the soft-tissue profile might play a key role in deciding on premolar extraction or non-extraction (ne) treatment, particularly in borderline patients. the purpose of this cephalometric study was to examine the soft-tissue treatment effects of class ii ...

A novel flattened bamboo-wood composite cross-laminated timber (CCLT) made from bamboo and hemlock lumber was developed, its mechanical performance investigated quantified in this work. The results demonstrated that the CCLT columns control CLT counterparts had nearly equal axial compression strength, but yielded a higher modulus of elasticity (MOE). Additionally, behaviors were not significant...
