British Journal of Orthodontics, 1990
Ceramic brackets have been understandably welcomed by patients; they are the best attempt so far at producing an orthodontic appliance which combines the aesthetic needs of the patient with the technical performance required by the orthodontist.

American Journal of Orthodontics and Dentofacial Orthopedics, 1994
The purpose of this study was to evaluate whether shear, tensile, or torsional forces were best suited for debonding ceramic brackets. Four commercially available ceramic brackets were evaluated. The brackets included both polycrystalline and monocrystalline types with either chemical or mechanical retention in the bracket bases.

Methods of Debonding Ceramic Brackets
British Journal of Orthodontics, 1992The problem of debonding ceramic brackets is still one which concerns the orthodontist. It is advisable to use the manufacturers recommended method of debonding each particular type of bracket. The risks of using such brackets need to be carefully assessed against the benefits. Risks can be minimized by carefully assessing the patient and the dentition,

The effect of topical fluorides on ceramic brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 1994Topical fluorides are frequently prescribed to orthodontic patients to minimize development of initial carious lesions around brackets and bands. However, various topical fluorides are reported to cause surface changes and weight loss of dental materials composed of ceramic elements. Little is known of the effects of these fluorides on ceramic brackets.

Diode laser debonding of ceramic brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 2010Our objective was to investigate the effectiveness of debonding ceramic brackets with a diode laser.Two types of ceramic brackets (monocrystalline and polycrystalline) were bonded to bovine maxillary central incisors. The diode laser was applied to brackets in the experimental groups for 3 seconds.

Shear bond strength of metal brackets compared with a new ceramic bracket
American Journal of Orthodontics and Dentofacial Orthopedics, 1988One hundred twenty bovine teeth were bonded with two types of metal brackets and a new ceramic bracket for comparison. Two different adhesives were used, a so-called no-mix and a paste/paste adhesive. The shear bond strength of the ceramic bracket was found to be superior for both adhesives.

Direct light transmittance through ceramic brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 1995The objective of this study was to investigate the degree of direct light transmittance (%T) of various types of esthetic brackets and to correlate these values with their structure, morphologic factors, and composition. Eight types of brackets were used in the study; six brackets of each type were tested.

Debonding orthodontic ceramic brackets by ultrasonic instrumentation
American Journal of Orthodontics and Dentofacial Orthopedics, 1995Breakage of ceramic brackets because of brittleness may cause such problems as aspiration of fragments and injury by flying debris. Portions remaining on the tooth must be laboriously ground off with a handpiece. This study investigated a potential method of lowering the force required to remove ceramic brackets, i.e., use of an ultrasonic chisel ...

Enamel fracture caused by ceramic brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 1991I n the past few years orthodontists have given more attention to the esthetic aspect of the appliances they use to achieve tooth movement, especially brackets. Recently, the demand for esthetic appliances has been answered by the introduction of translucent and transparent alumina brackets . ' Ceramic brackets (single crystal and polycrystall ine) are

Laser-aided debonding of orthodontic ceramic brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 1992The removal of ceramic brackets from the enamel surface by means of laser heating was investigated with the use of CO2 and YAG lasers. The two bracket types investigated were polycrystalline alumina and monocrystalline alumina. The average torque force necessary to break the adhesive between the polycrystalline ceramic brackets and the tooth was ...
