Communication practices and preferences between orthodontists and general dentists.
Abstract Objective: To evaluate similarities and differences in orthodontists' and general dentists' perceptions regarding their interdisciplinary communication. Materials and Methods: Orthodontists (N  =  137) and general dentists (N  =  144) throughout the United States responded to an invitation to participate in a Web-based and mailed survey, respectively. Results: The results indicated that orthodontists communicated with general dentists using the type of media general dentists preferred to use. As treatment complexity increased, orthodontists shifted from one-way forms of communication (letters) to ...

In vitro evaluation of microbial contamination of orthodontic brackets as received from the manufacturer using microbiological and molecular tests.
Conclusions: Brackets of two brands (Morelli and Abzil-3M Unitek) were found to be contaminated by bacteria in the original packages supplied by the manufacturers, which suggests a risk for patient contamination. These data suggest that the manufacturers of these materials should improve the quality control of the packaging used, including sterilization, for the security of patient health.

Effects of variable attachment shapes and aligner material on aligner retention.
Conclusions: Ellipsoid attachments had no significant influence on the force required for aligner removal and hence on aligner retention. Essix ACE showed significantly less retention than CA-hard on the models with attachments. Furthermore, beveled attachments were observed to increase retention significantly, compared with ellipsoid attachments and when using no attachments.

Conclusions: Class II correction using an XBow or Twin-block followed by fixed appliances occurs through a relatively similar combination of dental and skeletal effects. An increase in mandibular incisor inclination for the XBow group and an increased corpus length for the Twin-block group were notable exceptions. No overall treatment length differences were seen.

A pilot clinical study of Class III surgical patients facilitated by improved accelerated osteogenic orthodontic treatments.
This study was also designed to determine whether or not an IAOO procedure affects the tooth-moving pattern during extraction space closure. Materials and Methods: The samples in this study consisted of 24 Class III surgical patients.
