Objective: To test the hypothesis that the there is no difference between the shear bond strengths of different base designs of ceramic brackets bonded to glazed feldspathic porcelains. Materials a...
The mechanical properties of ceramic brackets, particularly fracture toughness, are so different from those of metal brackets that their selection and handling requires a completely different set ...
The purpose of this study was to compare the fracture strength of different ceramic brackets under different surface conditions and ligation methods using a torsional wire bending force. Five differ...
The purpose of this investigation was to determine the shear and tensile bond strengths of various ceramic and ceramic-filled brackets in combination with commonly used bonding systems, One monocr...
Ceramic brackets became popular as esthetic appliances which could withstand orthodontic forces and resist staining better than plastic brackets. Several clinical complications may arise from the us...
This study tested the strength of ceramic orthodontic brackets subjected to mesial-distal tipping forces on five types of pre-adjusted, maxillary right central incisor ceramic twin brackets for bo...
Debonding ceramic brackets is an area of concern to clinicians. Reports of enamel fractures and cracks have raised questions about the safety of the procedures used to remove these attachments.
Improper orthodontic bracket position may necessitate bracket removal and rebonding to establish correct bracket position. This procedure is necessary to use efficient orthodontic mechanics. The p...
The present study compared tooth-bracket bond strengths using two types of ceramic brackets and three methods of polymerization: argon laser, conventional light, and chemical. Ninety extracted hum...
Shear bond strengths of a light-cured composite resin, a light-cured glass ionomer cement, and a light-cured compomer used with metal and ceramic brackets were compared, and ARI scores were evalua...
The aim of this in vitro investigation was to test whether disinfecting with Chlorhexamed® fluid had an influence on the shear bond strength of metal and ceramic orthodontic brackets. Metal and ...
The objectives of this study were to test the efficiency of LED curing devices in bonding ceramic brackets to porcelain surfaces and to compare the effects of LED and halogen curing techniques on ...
The aim of this study was to examine the shear bond strength between Hyaline brackets, a new type of calcium phosphate ceramic bracket, and human enamel using various types of adhesive resin and to ...
Objective: To compare the level of friction resistance (FR) of conventional and silica-insert ceramic brackets using various bracket-wire combinations and angulations.Materials and Methods: Four types...
