One of the most essential clinical concepts learned by a future orthodontist is the effective placement of orthodontic brackets. This skill is present at the core of any orthodontic residency clinical curriculum; yet research documenting the most effective methods of teaching this indispensable skill is lacking. The purpose of this pilot study is to assess the impact of different pedagogical mo...

introduction: one of the most common problems we confront in orthodontic therapy is periodontal diseases. initial factor which causes these diseases is colonization of anaerobic microorganisms in subgingival plaque. technically, local environmental changes related to orthodontic band and brackets may influence the bacterial species in periodontal plaque. however, it seems necessary to assess va...

The application of bleaching agents before placement of resin-bonded fixed appliances significantly, but temporarily, reduces bond strength to tooth structure. Antioxidants have been studied as a means to remove residual oxygen that compromises bonding to bleached enamel. This in vitro study evaluated whether green tea (GT) could restore the shear bond strength between bonded orthodontic bracke...

This article describes a new method of preparing trays for indirect bracket bonding. Computer-aided technology is used to design the individualized trays, which are then produced with a rapid prototyping procedure. Application in clinical practice and the advantages of time savings and accurate bracket placement are discussed.

BACKGROUND So far, a few studies have tried to investigate the relationship between the placement of fixed orthodontic appliances and the change of nonmicrobial salivary properties, mostly with conflicting outcomes and short-term assessment (up to 6 months from bracket placement). The purpose of this study was to evaluate the salivary flow rate, pH and buffer capacity prior to the beginning of ...

The accuracy of brackets placement is a key factor in successful orthodontic therapy. An in vitro study was conducted in ten models from a natural maxillary teeth model in order to compare the accuracy of brackets placement between two direct bonding instruments: the pole-like Bracket Positioning Gauge and the star-like Bracket Positioning Gauge. Our results have shown that: the star-like Brack...
