Bond Strength of Orthodontic Adhesives
The objective of this study was to evaluate and compare bond strength of four adhesives used in orthodontics for bonding brackets to tooth enamel. The adhesives used in this investigation were resin-reinforced glass-ionomer cement (Fuji Ortho LC-GC Corporation, Japan), light cured composite resin adhesives (ConTec LC-Dentaurum, Germany and Enlight Bonding system-Ormco, USA) and dual cured compo...
متن کاملThe inappropriateness of conventional cephalometrics.
1. Cephalometric conventions today may have little basis in either biology or biometrics. 2. There is no theory of cephalometrics, only conventions which involve landmarks and straight lines only. These fail to capture the curving of form and its changes, exclude proper measures of size for bent structures, and misrepresent growth, portraying it as vector displacement rather than a generalized ...
متن کاملComparison in Shear Bond Strength of Orthodontic Brackets between Biofix and Conventional Bonding Systems
Background and objectives: The aim of the study was to evaluate the shear bond strength of brackets bonded with three bonding systems under laboratory conditions and to compare resin tag penetration after debonding. Materials and methods: The study was done on 60 extracted human premolar teeth, divided into three groups of 20 teeth each. Each group was bonded with three different types of bondi...
متن کاملLaser Etched vs Conventional Etched Enamel: Effect on Shear Bond Strength of Orthodontic Brackets
Aim: The purpose of this study was to assess the shear bond strength of the teeth prepared for bonding with different power outputs of Erbium, Chromium doped: Yttrium-ScandiumGallium-Garnet (Er,Cr:YSGG) laser etching and to compare different power outputs of laser etching with 37% phosphoric acid. Materials and methods: A total of 105 premolars, extracted for orthodontic purposes were randomly ...
متن کاملShear bond strength comparison between two orthodontic adhesives and self-ligating and conventional brackets.
OBJECTIVE To evaluate and compare the shear bond strengths of two adhesives using two types of brackets: a conventional and a self-ligating bracket system. MATERIALS AND METHODS Sixty extracted human premolars were collected. The premolars were randomly divided into three groups of 20 teeth. All three groups were direct bonded. Groups 1 and 2 used light-cured adhesive and primer (Transbond XT...
