Abstract
Myofunctional therapy plays a significant role in the orthopaedic correction of malocclusions, particularly in growing patients, by utilizing and modifying functional forces generated by the orofacial musculature. These therapies aim not only to correct dental irregularities but also to address underlying etiological factors such as abnormal muscle activity, tongue posture, and oral habits. Over time, myofunctional appliances have evolved from traditional functional devices to modern prefabricated systems, offering improved patient comfort, reduced chairside time, and enhanced clinical efficiency.
This review highlights the contemporary concepts of myofunctional therapy, focusing on various appliance systems including pre-orthodontic trainers, thermoformable and non-thermoformable trainer systems, Myobrace appliances, functional activators, and the Equilibrator Oral System Appliance (EQ O.S.A.). The mechanisms of action, clinical protocols, indications, and therapeutic effects of these appliances are discussed in detail. Additionally, conventional functional appliances such as the Bionator and Twin Block, including modified designs like the Essix Twin Block, are reviewed with respect to their skeletal, dentoalveolar, and neuromuscular effects.
Despite certain limitations such as dependence on patient compliance and restricted tooth movement capability, myofunctional therapy remains an essential component of interceptive and preventive orthodontics. Current approaches emphasize early intervention and correction of functional abnormalities to achieve stable, long-term outcomes. A comprehensive understanding of appliance selection, timing, and patient cooperation is crucial for optimizing treatment success.
