This study ascertained the influence of orthodontic appliances on subjective ratings for social competence (SC), intellectual ability (IA), psychological adjustment (PA), and attractiveness in young adult orthodontic patients. A cross-sectional analytical questionnaire study was conducted with 130 undergraduates from the UK. Each participant was asked to look at a single, randomly assigned colo...

objective: this in vitro study evaluated the fracture strength and bending amount of twotypes of fiber reinforced composite (frc) and cast metal frameworks used for fabrication of inlay fixed partial dentures (ifpds). materials and methods: seventy-two extracted first maxillary premolars and molars (36 each) were embedded in acrylic resin to represent a missing of second maxillary premolar. frc...

This article describes the construction of the FR-3 appliance classically used in cases of Class III malocclusion characterized by maxillary skeletal retrusion. Included is a description of proper impression technique, construction bite registration, preparation of the work models, and a complete description of the fabrication of the FR-3 appliance. Specific steps in the clinical management of ...

Power management in homes and offices requires appliance usage prediction when the future user requests are not available. The randomness and uncertainties associated with an appliance usage make the prediction of appliance usage from energy consumption data a non-trivial task. A general model for prediction at the appliance level is still lacking. In this work, we propose to enrich learning al...

The loss of multiple primary molars in the primary or transitional dentition will, in many instances, lead to disturbances of the developing dentition. To prevent this, an appliance can be constructed to maintain the relationship of the remaining teeth and to guide the eruption of the developing teeth. Traditionally, the treatment of choice for maxillary loss is the placement of a Nance applian...

JL he combination of acid-etching and bonding has led to dramatic changes in the practice of orthodontics. Newman began the revolution in orthodontics with the advent of epoxy-bonded attachments. Bonding has evolved and now is used for; placement of attachments, various types of retainers, and resin build-ups which address tooth size and shape problems encountered during orthodontic treatment. ...

Network Appliance recently began shipping a new kind of network server called an NFS file server appliance, which is a dedicated server whose sole function is to provide NFS file service. The file system requirements for an NFS appliance are different from those for a general-purpose UNIX system, both because an NFS appliance must be optimized for network file access and because an appliance mu...

Orthodontists from different backgrounds may have different opinions about removable and fixed orthodontic appliances, but there have been few objective comparisons of their relative treatment effectiveness. It is the purpose of the present study to analyze objectively the effectiveness of these two types of appliances. Eighty cases involving patients who had been treated with removable applian...
