The duration of post-orthodontic retention is a critical consideration following completion of teeth straightening treatment. It involves the continued use of a custom-made appliance to maintain the achieved alignment. Failure to adhere to recommended guidelines can result in relapse, where teeth shift back towards their original positions.
Retention plays a vital role in stabilizing the dentition after active orthodontic treatment. Newly straightened teeth are susceptible to movement due to the elasticity of periodontal fibers and ongoing skeletal growth. Consistent appliance usage mitigates these forces, preserving the investment made in achieving a corrected bite and esthetic smile. The principles of retention have evolved over time, with advancements in appliance design and a better understanding of the biological factors influencing tooth stability.
