A removable appliance, fabricated from acrylic and wire, is designed to maintain the alignment of teeth following orthodontic treatment. This appliance encases the entire dental arch, offering comprehensive support to prevent relapse. It typically consists of an acrylic base that covers the palate or lingual aspect of the lower arch, with wires extending to secure the teeth.
Post-orthodontic retention is a critical phase in ensuring the long-term success of teeth straightening. Without adequate retention, teeth can gradually shift back towards their original positions. The described appliance plays a significant role in stabilizing teeth, preventing unwanted movement, and preserving the investment made in orthodontic treatment. Its full coverage design distributes forces evenly, promoting stability and minimizing the risk of relapse. Historically, such retainers have evolved from simpler designs to provide enhanced retention capabilities.
