A dental retainer maintaining a less secure fit on one lateral aspect indicates an imbalance in the forces it exerts on the teeth. This perceived looseness suggests that the appliance is not uniformly engaging with the dentition as intended following orthodontic treatment.
Understanding the reasons behind this uneven fit is crucial for preserving the stability achieved through prior orthodontic intervention. Addressing this issue promptly can prevent potential relapse, where teeth begin to shift back towards their original positions. Regular and consistent fit of the retainer ensures continued alignment and bite stability.
