Debonding of ceramic brackets by a new scanning laser method
American Journal of Orthodontics and Dentofacial Orthopedics, 2010The purpose of this in-vitro study was to develop a new method to debond ceramic brackets by scanning with an Er:YAG laser.Sixty bovine mandibular incisors were randomly divided into 2 groups of 30. Polycrystalline ceramic brackets were placed on their labial surfaces by using the orthodontic composite adhesive Transbond XT (3M Unitek, Monrovia, Calif)

The Method of Brackets in Experimental Mathematics
2018© 2018 by World Scientific Publishing Co. Pte. Ltd. All Rights Reserved. The method of brackets is a new method originally developed in the context of definite integrals coming from the evaluation of Feynman diagrams. It consists on a small number of heuristic rules. The work presented here describes these rules and illustrates the method. The example

New method of brackets positioning for orthodontic treatment of dentoalveolar anomalies
Stomatologiya, 2018The aim of the study was to improve the accuracy of the positioning of brackets in the conduct of orthodontic treatment of the anomalies of the dentoalveolar system. The developed method of positioning the brackets assumes a temporary fixation of the wire guides in accordance with the prospective longitudinal axis of the tooth before carrying out the ...

Distortion of edgewise orthodontic brackets associated with different methods of debonding
American Journal of Orthodontics and Dentofacial Orthopedics, 1989The effects of three different methods of bracket removal on the dimensions of the arch wire slot of edgewise brackets were examined. Gross distortion (visible to the naked eye) and microscopic distortion were found for all three methods. Gross bracket distortion was found infrequently with one method.

Comparative study of different methods for orthodotic bracket debonding
Novel Optical Systems, Methods, and Applications XXIII, 2020This study was designed to ceramic brackets debonding through conventional remove and two lasers (980 nm diode laser and 1064 nm Nd:YAG laser) irradiation on the interface between the teeth and the bracket. After bracket removal, the enamel surfaces were examined using a digital microscope and the corresponding adhesive remnant index (ARI) score was ...

[New indirect method of orthodontic bracket application].
Mondo ortodontico, 1991The latest improvements in orthodontic materials need an extremely accurate placement of brackets on the teeth. Such degree of precision, hardly obtainable with normal technique, led to develop many indirect techniques of bracket bonding: they had however many defects, limiting the clinical use such as: 1) impossibility to remove accurately the bonding

Numerical method for lightning transient analysis of photovoltaic bracket systems
Journal of Renewable and Sustainable Energy, 2020A calculating method is proposed for lightning transient analysis in photovoltaic bracket systems. The circuit parameters are evaluated for the conducting branches and grounding electrodes. On the ground of the circuit parameters, the equivalent circuit model is set up for photovoltaic bracket systems.

AN ALGORITHMIC COMPARISON OF DERIVATIVE-FREE VERSUS BRACKETED METHODS
This paper presents a numerical study comparing the performance of several iterative methods for solving nonlinear equations. We analyze the Bisection method, Newton-Raphson’s method, Secant method, Müller’s method and Regula falsi method. By applying these methods to a specific function, we compare their convergence rates and computational efficiency.Ria Sharma, Surabhi

[Enamel damage depending on the method of bracket removal].
Fortschritte der Kieferorthopadie, 1993Two different methods of removing brackets, on the one side by torsion and on the other by bending, were compared for the purpose of analyzing the respective enamel lesions. Each test group consisted of 19 extracted human molars with metal brackets attached to the molars by means of the "concise etching technique".
