Sentence examples for bracket interface from inspiring English sources
The chisel was positioned parallel to the vestibular surface of the tooth and bracket interface to allow force transmission in the occlusal-gingival direction.
In demineralised enamel, microleakage occurred mainly at the enamel-adhesive than the adhesive bracket interface, proposing a greater risk of enamel demineralisation upon occurrence of microleakage.
Space closure may be more dependent on the second order wire-to bracket interface than on the first order, where design differences between brackets are apparent.
A mounting jig was used to align the tooth-bracket interface parallel to the testing device.
The frictional test of each archwire-bracket interface was carried out using a universal testing machine (Model 5848 Micro Tester, Instron Corporation, Norwood, MA, USA).
Corrosion and its effect of increasing surface roughness have the potential to increase frictional force at the wire-bracket interface [11].
Group 4 (demineralised/SEP) also revealed significantly more microleakage than group 3 (demineralised/NaOCl) at the adhesive-bracket interface of the gingival side (P < 0.005; Table 1).
When the adhesive-bracket interface was considered, group 4 (demineralised/SEP) displayed significantly higher microleakage values than did groups 2 (demineralised/control) and 5 (demineralised/NaF) along both occlusal and gingival margins (P < 0.005; Table 1).
In this study, preparation of hypomineralised enamel with Transbond Plus self-etching primer caused significantly higher microleakage at the adhesive-bracket interface than when the conventional acid-etching or NaF treatment were used.
The authors also found that Aegis Ortho had lower flexural strength, which would explain for the material failure at the adhesive-bracket interface rather than the enamel adhesive interface [54].
However, in the above mentioned studies [22, 23], the statistical difference between the microleakage scores of self-etching and conventional acid etching was noted at the enamel-adhesive rather than the adhesive-bracket interface.
