Summary
Colored elastomeric chains initially provide adequate force for tooth movement. However, their force delivery and dimensional stability degrade after prolonged exposure to simulated oral environments, varying by manufacturer.
Area of Science:
- Orthodontics
- Biomaterials Science
Background:
- Elastomeric chains are standard orthodontic tools.
- Colored elastomeric chains are a recent addition by manufacturers.
- Their clinical performance requires investigation.
Purpose of the Study:
- To evaluate the force delivery capabilities of colored elastomeric chains.
- To assess the dimensional stability of colored elastomeric chains.
- To compare different colors and manufacturers under simulated oral conditions.
Main Methods:
- Tested four colors from three manufacturers.
- Assessed force delivery at multiple time points (0-3 weeks) in air, distilled water, and artificial saliva.
- Measured dimensional stability after simulated oral exposure.
- Utilized a universal testing machine and factorial analysis of variance.
Main Results:
- All chains initially generated sufficient force for tooth movement.
- Force delivery significantly decreased after 24 hours in liquid environments.
- Dimensional measurements increased after one week and remained stable thereafter.
- Variations in performance were observed among manufacturers.
Conclusions:
- Colored elastomeric chains demonstrate initial efficacy but exhibit reduced force over time.
- Degradation in simulated oral environments impacts long-term force delivery.
- Manufacturer and color may influence the stability and performance of these orthodontic materials.
