The Power of Precision: T-Mixer™ Colibri™ Proves Superior in Resin Cement Polymerization

In restorative dentistry, the effectiveness of resin cement relies heavily on its degree of polymerization, which directly impacts the material's strength, durability, and long-term performance.** A recent evaluation conducted by Prof. Dr. Alexandre Coelho Machado at the Universidade Federal de Uberlândia underscores the critical role of mixing methods in achieving optimal polymerization. The study compared three mixing techniques—manual (spatula), helical mixing tips, and the T-Mixer Colibri mixing tip—revealing how advanced technology enhances clinical outcomes.

Study Highlights: Evaluating the Conversion Degree of Resin Cement

The primary objective of the study was to analyze the conversion degree (CD) of a dual-cure resin cement under different mixing methods and curing conditions. The conversion degree, expressed as a percentage, reflects the transformation of monomers into polymers, indicating the quality of polymerization. The study considered two curing methods: chemical polymerization and dual polymerization (chemical and light curing).

Mixing Methods Evaluated:

  1. Manual mixing with a spatula
  2. Helical mixing tip (type S)
  3. T-Mixer™ Colibri™ mixing tip

Key Findings

  1. Superior Chemical Polymerization with T-Mixer Colibri
    Among the three mixing methods, the T-Mixer Colibri achieved the highest conversion degree during chemical polymerization (50.79%)*, significantly outperforming both manual mixing (25.93%)* and helical mixing tips (41.57%)*. This highlights the T-Mixer's efficiency in challenging clinical situations where light access may be limited.
  2. Enhanced Conversion with Mixing Tips vs. Manual Techniques
    Both the T-Mixer Colibri and helical mixing tips showed substantially higher conversion degrees compared to manual mixing with a spatula. This demonstrates that mixing tips are essential for achieving optimal chemical polymerization, especially in scenarios where light curing may not penetrate thick cement layers or hard-to-reach areas.*
  3. Dual Polymerization Achieves Comparable Results Across Techniques
    When dual polymerization was used, all three mixing methods resulted in similar conversion degrees. However, in complex clinical situations where light curing is insufficient, the superior performance of the T-Mixer Colibri during chemical polymerization remains a critical advantage.*
