Debonding characteristics of a polymer mesh base ceramic bracket bonded with two different conditioning methods.
The aim of this study was to compare the shear bond strength (SBS) and debonding characteristics of a polymer mesh base ceramic bracket bonded with two different surface conditioning methods. InVu Readi-Base ceramic brackets were bonded to 100 human premolars with different etching protocols. With conventional method (CM), the teeth were etched with 37 per cent phosphoric acid for 30 seconds, w...
متن کاملHandling characteristics of precoated and operator-coated brackets.
introduced in 1991 to save the clinician the time spent in preparing the adhesive for direct bonding and applying it to the bracket.1 The APC brackets, which are packaged in individual capsules for ease of identification and infection control, are applied with finger pressure.2 A uniform factory precoating purportedly ensures an even amount and consistency of composite beneath each bracket. Any...
متن کاملLED vs halogen light-curing of adhesive-precoated brackets.
OBJECTIVE To test the hypothesis that bonding with a blue light-emitting diode (LED) curing unit produces no more failures in adhesive-precoated (APC) orthodontic brackets than bonding carried out by a conventional halogen lamp. MATERIALS AND METHODS Sixty-five patients were selected for this randomized clinical trial, in which a total of 1152 stainless steel APC brackets were employed. In or...
متن کاملShear bond strength of ceramic brackets with various base designs bonded to aluminous and fluorapatite ceramics.
This study was conducted to evaluate the shear bond strength (SBS) of various ceramic bracket base designs bonded to glazed aluminous (Vitadur Alpha) and fluorapatite (IPS e.max Ceram) ceramics, to examine the mode of failure, and to determine the debonding characteristics of the brackets and the ceramic surfaces after bond failure. Forty ceramic discs (15 mm in diameter and 1.5 mm thick) of ea...
متن کاملEnergy harvesting performance of piezoelectric ceramic and polymer nanowires.
Energy harvesting from ubiquitous ambient vibrations is attractive for autonomous small-power applications and thus considerable research is focused on piezoelectric materials as they permit direct inter-conversion of mechanical and electrical energy. Nanogenerators (NGs) based on piezoelectric nanowires are particularly attractive due to their sensitivity to small-scale vibrations and may poss...
