Hypothesis
The study aims to evaluate the force extension relaxation of different brands and diameters of latex elastics under simulated oral conditions.
Conclusion
The study found that Morelli elastics maintained the greatest loads, while AO had greater loads than Tp for medium force elastics.
Supporting Evidence
- The study tested elastics from three different manufacturers.
- Force measurements were taken at multiple time intervals to assess decay.
- Statistical analysis showed significant differences among the brands.
Takeaway
This study looked at how well different rubber bands used in braces hold their strength over time. Some brands worked better than others.
Methodology
Five medium force orthodontic latex elastics were tested at six time intervals (0, 1, 3, 6, 12, and 24 hours) to measure force decay in a simulated oral environment.
Limitations
The study was limited by the time available for transferring elastics and measuring force, and artificial saliva was not used due to its viscosity.
