Efficacy Of Modified Bidimensional Bracket System in Orthodontic Management of Bimaxillary Protrusion: A Comparative Analysis
Keywords:
Bidimensional system, Anchorage control, Orthodontic retractionAbstract
Background: bimaxillary protrusion is a common orthodontic concern that often requires extraction-based treatment followed by space closure. Efficient retraction mechanics with minimal anchorage loss are crucial for achieving optimal treatment outcomes. While the conventional MBT bracket system is widely used, the modified bidimensional bracket system has been proposed as an alternative to enhance control over anchorage while enabling faster tooth movement.
Objective: This study aimed to compare the rate of retraction and anchorage loss in patients with skeletal or dentoalveolar bimaxillary protrusion treated with the conventional MBT bracket system and the modified bidimensional bracket system.
Methods: A total of 10 patients with bimaxillary protrusion were selected and divided into two groups (n=5 per group). Group A was treated with the conventional MBT bracket system, while Group B received treatment with the modified bidimensional bracket system. Lateral cephalograms were used to evaluate the rate of retraction and anchorage loss for each patient.
Result: The findings revealed significant differences between the two groups in terms of retraction efficiency and anchorage control. The modified bidimensional bracket system demonstrated significant control over anchorage while maintaining an effective rate of retraction compared to the conventional MBT bracket system.
Conclusion: The modified bidimensional bracket system may offer clinical advantages in cases requiring efficient space closure with minimal anchorage loss. Further studies with larger sample sizes are recommended to validate these findings
