The adhesive material used to bond orthodontic brackets to teeth should neither fail during the treatment period, resulting in treatment delays, untoward expenses or patient inconvenience nor should it damage the enamel on debonding at the end of the treatment. Although the effectiveness of a bonding system and any unfavorable effects on the enamel may be studied by conducting in-vivo studies, ...

A Novel Bioactive Glass-Enhanced Orthodontic Bonding Resin: A shear bond strength study By Cole R. Johnson, D.D.S. A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Dentistry at Virginia Commonwealth University. Virginia Commonwealth University, 2011 Thesis Director: Eser Tüfekçi, D.D.S, M.S., Ph.D Associate Professor, Department of Orthodontic...

strength, flexural modulus, and contraction stress of one orthodontic composite and two flowable composites. Orthodontic brackets were bonded to 45 human maxillary premolars with the composites Transbond XT, Filtek Z-350 flow and Opallis flow and tested for shear bond strength. For measurement of flexural strength and flexural modulus, specimens were fabricated and tested under flexion. For the...

AIM The study was undertaken to measure the changes within the mesh pad associated with reconditioning process, measure the bond strength of new and reconditioned orthodontic brackets and correlate the changes in mesh strand diameter with changes in bond strength. MATERIAL AND METHODS 120 clinically normal premolar teeth extracted for orthodontic reasons, were divided equally for bonding with...

Introduction A great number of techniques have been used for bonding orthodontic brackets to the tooth surfaces. Glass ionomer cements are frequently used material for this purpose. The aim of this study was to measure the shear bond strength of orthodontic brackets bonded with glass ionomer cement Ortho Fuji LC and remained adhesive on the enamel surface after brackets debonding. Material and ...

OBJECTIVE Increased number of adult patients requesting orthodontic treatment result in bonding bracket to ceramic restorations more than before. The aim of this study was to evaluate and compare the shear bond strength of orthodontic brackets bonded to two types of ceramic bases with conventional orthodontic bonding resin and a new nano-filled composite resin. MATERIALS AND METHODS Twenty fo...

The aim of this study was to compare the in vitro bond strength to enamel measured in shear of the light-activated bonding agent Heliosit-Orthodontic with the shear bond strength of the two-paste bonding resin Concise and the 'no-mix' bonding resin Right-On. In a number of separate tests involving 205 teeth and 267 bonds, the Heliosit-Orthodontic is shown to form a stronger bond to canine teeth...

the purpose of this study was to compare shear bond strength (sbs) of orthodontic brackets bonded to enamel prepared by er:yag laser with two different powers and conventional acid-etching.forty-five human premolars extracted for orthodontic purposes were randomly assigned to three groups based on conditioning method: group 1- conventional etching with 37% phosphoric acid; group 2- irradiation ...

OBJECTIVES Satisfactory bonding of orthodontic attachments to amalgam is a challenge for orthodontists. The aim of this in vitro study was to compare the shear bond strength of stainless steel orthodontic brackets to silver amalgam treated with sandblasting and Er,Cr:YSGG laser. STUDY DESIGN Fifty-four amalgam discs were prepared, polished and divided into three groups: In group 1 (the contro...
