Summary
Glass ionomer cement (GIC) offers a viable alternative for bonding orthodontic brackets, significantly reducing enamel decalcification. This clinical study details the successful chairside technique for GIC bracket bonding.
Area of Science:
- Orthodontics
- Dental Materials Science
Background:
- Composite resin is the conventional orthodontic bracket adhesive.
- Glass ionomer cement (GIC) has been underutilized in orthodontics.
- GIC offers potential benefits in reducing enamel decalcification.
Purpose of the Study:
- To evaluate the clinical experience of using GIC for bonding orthodontic brackets.
- To compare the incidence of enamel decalcification with GIC versus composite resin.
- To define critical factors and chairside techniques for successful GIC bracket bonding.
Main Methods:
- A clinical study involving seven practitioners over six years.
- Bonding of approximately 99% of metal orthodontic brackets using GIC.
- Documentation of clinical advantages, disadvantages, and bonding technique.
Main Results:
- High success rate (99%) in bonding orthodontic brackets with GIC.
- Significantly lower incidence of tooth enamel decalcification compared to composite resin adhesives.
- Identification of critical factors for successful GIC bonding.
Conclusions:
- GIC is a clinically effective alternative for orthodontic bracket bonding.
- GIC use is associated with a reduced risk of enamel decalcification.
- A defined chairside technique ensures successful GIC bracket bonding.
