The use of visible light-curing composites in bonding ceramic brackets
1Department of Orthodontics, Universitäts Krankenhaus Eppendorf, West Germany.
Summary
Light-curing adhesives offer advantages for bonding ceramic brackets, showing adequate strength with proper consistency and no need for primer. No significant differences in bond strength were found among tested materials.
Area of Science:
- Dental Materials Science
- Orthodontic Adhesion Technology
Background:
- Ceramic brackets are widely used in orthodontics.
- Effective bonding of ceramic brackets is crucial for successful treatment.
- Current bonding materials require evaluation for optimal performance.
Purpose of the Study:
- To compare the bond strength of ceramic brackets bonded with various materials.
- To evaluate the efficacy of light-curing adhesives in orthodontic bonding.
- To determine if primer is necessary for bonding ceramic brackets.
Main Methods:
- Three hundred fifty bovine teeth were bonded with ceramic brackets using nine different adhesive materials.
- Materials included conservative composites, light-curing orthodontic adhesives, and chemically curing adhesives.
- Some materials were modified by resin dilution; bond strength was assessed after a 20-second curing time.
Main Results:
- Adequate bond strength was achieved with a 20-second curing time when proper consistency was maintained.
- Primer was not necessary for bonding when the material consistency was appropriate.
- No statistically significant differences in bond strength were observed among the nine tested materials.
Conclusions:
- Light-curing adhesives present several advantages for bonding ceramic brackets.
- Optimized material consistency can eliminate the need for primer.
- Various adhesive materials demonstrate comparable bond strengths in this study.
